Slocomb Windows Review 2025: Prices, Quality & Real Homeowner Insights

If you’re shopping for replacement windows and have come across Slocomb Windows, you might wonder whether this regional manufacturer offers good value for your home. Slocomb isn’t as widely known as ProVia or Simonton, but they’ve been quietly building a loyal following for over four decades — and there’s a good reason for that.

This 2025 Slocomb Windows Review will give you everything you need to know about pricing, performance, efficiency ratings, warranty coverage, and how they stack up against competitors.


🏆 Quick Verdict

Slocomb Windows are a solid, made-in-the-USA vinyl window option for homeowners in the Mid-Atlantic and Northeast. However you should not ignore the risk of working with a small manufacturer like this.
They offer dependable performance, ENERGY STAR efficiency, and a fair price point. While not luxury-grade, their 677 Series provides one of the best cost-to-value ratios in the region. In my opinion there is no need to take a gamble on a company like this as they don’t offer anything that is really unique.

Best for: Homeowners looking for a dependable, affordable vinyl replacement window.
Not ideal for: Those who want premium finishes or nationwide availability.

About Slocomb Windows

Slocomb Windows & Doors, headquartered in Pennsylvania, has been manufacturing vinyl windows for more than 40 years. The company focuses on energy-efficient designs and custom-sized replacement windows.

They serve a mostly regional customer base — primarily in the Mid-Atlantic and Northeast U.S. — but have grown steadily thanks to solid quality and reliable service.

Their product lineup includes:

  • Slocomb 177 Series – Entry-level, budget-friendly replacement windows
  • Slocomb 557 Series – Mid-range option with improved glass and frame efficiency
  • Slocomb 677 Series – Premium model with better insulation and hardware upgrades

Build Quality: 78/100

Slocomb’s construction quality is respectable for its price point. Each window features fusion-welded vinyl frames for strength and rigidity. In higher-end models like the 677 Series, you’ll also find foam-enhanced frames for better thermal insulation.

Notable features include:

  • Stainless steel constant-force balances for smooth operation
  • Sloped sills for water drainage
  • Interlocking meeting rails to improve air tightness
  • Dual weatherstripping for enhanced performance

While Slocomb doesn’t match top-tier brands like Soft-Lite or ProVia, it’s reliable and easy to maintain — ideal for budget-conscious homeowners.


Energy Efficiency: 82/100

Energy efficiency is one of Slocomb’s strengths. With Low-E glassargon gas-filled chambers, and warm-edge spacers, their windows perform on par with other mid-range vinyl options.

  • U-Factors: As low as 0.27
  • SHGC Values: Down to 0.20 (depending on glass package)
  • ENERGY STAR 7.0 Certified: Yes, for most configurations

These ratings mean many Slocomb models qualify for the Federal Energy Efficient Home Improvement Credit (IRS 25C).

Slocomb windows efficiency ratings and reviews
Here you can see the efficiency ratings for the Slocomb 677 series windows. These numbers are fine for a triple pane window, but they’re not remarkable or unique. Some folks who appear to be salespeople selling Slocomb windows have written in to say these are raitings for double pane windows. I’ve asked for further clarification / confirmation of that and haven’t received a reply.

You can also explore official performance requirements on the ENERGY STAR website.

Design & Options: 75/100

Slocomb offers a modest range of design choices. You’ll find standard colors like white, almond, and clay, plus interior woodgrain finishes on select models.

Available styles include:

  • Double-hung
  • Casement
  • Slider
  • Awning
  • Bay & Bow
  • Garden windows

While customization options are limited compared to premium manufacturers like Marvin, the 677 Series still offers enough variety for most homeowners seeking traditional or modern looks.

Common Slocomb Window Complaints

Most homeowner reviews are positive, but common feedback includes:

  • Limited availability outside core regions
  • Longer lead times for custom colors
  • Occasional seal failures in older models

These issues are not unique to Slocomb — they’re typical of smaller, regional manufacturers.
To avoid headaches, always work with an authorized installer and verify their workmanship warranty.

“Slocomb might not be the most famous brand, but they’re quietly dependable. The big is comes from their being a much smaller company than their competitors. Their windows are sturdy, energy-efficient, and affordable — exactly what most homeowners need. The 677 Series in particular performs better than you’d expect for the price. If you’re looking for good value and made-in-America construction, Slocomb deserves a closer look.”

Crown Windows Reviews

If you’re looking for Crown windows reviews you’re probably in Michigan as they claim to be “The Michigan Window”. In fact they talk quite a bit about being the Michigan replacement window on their website. Are they offering a good deal? Let’s find out.

Before we get too far into this review I should note that my company does offer windows in Detroit and Grand Rapids. We don’t offer Crown windows so one might say we’re a competitor. If you’d like an easy online quote from my company we’d be happy to help. We can send a quote by email with no pushy salesman. Welcome to the future.

In looking at their website a few things jump out. First they say they manufacture and install the windows. They also say they’ve been in business since 1955. These sound like great reasons to work with them. They might also be downsides. In my experience the small local manufacturers who produce and install their own windows are some of the more expensive options around. I also write a lot about the risks of small manufacturers and those same risks would apply to Crown Windows.

The next thing we notice in working on the Crown windows reviews is that they make a lot of qualitative statements without much info to back it up. Here’s one example:

crown windows air infiltration

As you can see they say they “stop air infiltration”, but without an actual rating it’s impossible to know if they’re doing better than any other window. If you’re considering Crown Windows my advice is to ask them for the specific rating for the window you’d be getting. Generally speaking an air infiltration rating under 0.10 is pretty decent and under 0.05 is better. If the air infiltration rating is over 0.10 it’s not so great after all.

Here’s another example:

crown windows foam filled frames

You can see they say their special foam offers exceptional resistance to thermal transfer but we don’t really have any information about what that means. If you’re considering these windows ask for the U-Factor to understand how these windows will compare with other options. To be Energy Star rated in the northern climate zone the U-Factor needs to be under 0.30 and there are other ratings, like the SHGC, that will also be important to consider.

What else to consider with Crown Windows reviews?

There are several other selling points they use that may sound fancy but aren’t really unique. These features will be offered by many companies. Features like Super Spacer, or high-performance vinyl are very widely available and aren’t really unique to Crown at all.

If the salesman goes on and on about how they offer these super special features I’d discount most of what he has to say. These are fine features but really not very special at all.

Are Crown windows the same as Earthwise windows?

Yes. Crown is a manufacturer that makes windows under the Earthwise brand.

crown windows earthwise reviews

We’ve written about Earthwise before. As you can see in the comments on that page, some of the Earthwise salespeople don’t always agree with my assessments. That can be common. At the end of the day I don’t think it’s a great program.

What’s the bottom line?

Crown windows are perfectly fine, but there’s nothing about them that is particularly remarkable. The risks of working with a small window manufacturer are substantial. I’m not aware of any reason to take the gamble. The features they offer are perfectly nice but not unique.

If the salesman hasn’t explained why you should take the gamble of working with a small window manufacturer I’d suggest looking elsewhere. You can get the same replacement window features and many more elsewhere.

How can you find a great window company?

When shopping for windows I do always suggest finding a great installation company before you fall in love with any particular window model. There are plenty of great window options out there but not as many local companies that are great to work with.

To know which companies to avoid you can find common window sales tactics here. That’s become one of the most popular sections on the site.

Remember, for more great window company info you can find our suggestions for the best local companies in Michigan and beyond right here. There’s no need to work with a company that gives you the run-around or makes the process difficult. There are plenty of fish in the sea as they say. The best way to get started is to check out our list of great window companies here.

Cascade Windows Reviews

Here you can find detailed Cascade windows reviews. Cascade is a window manufacturer in the west and southwest. They have facilities in Washington, Oregon, Utah and Arizona. You’ll find their dealers primarily located in the same areas.

In 2020 Cascade windows purchased the assets of Amerimax windows which had manufacturing facilities in Loveland, CO and Woodland, CA. This acquisition gave Cascade coverage in a wide swath of the western US.

The Cascade window options we’ll be looking at include:

  • Cascade Windows Reviews
  • WinPro Windows Reviews
  • Folding Windows
  • Multi-Slide Doors
  • Corner Doors
  • Folding Doors
  • Swing Doors
  • Patio Doors

What about the Cascade Windows warranty?

The warranty for these windows is pretty solid. It’s a lifetime warranty, but it does have some limitations to be aware of. For example, they don’t cover corrosion if the windows are within 2 miles of saltwater. For folks in Seattle that may be pretty important.

They also don’t cover glass breakage and only cover stress cracks in the glass for 60 days after the windows are installed. I could see that being a problem for some folks.

How can you find a great window company?

Alliance Window Systems Reviews 2026 – Honest Expert Take

If you’ve ended up on this page, you’ve probably run across Alliance Window Systems. They don’t have the name recognition of Andersen or Pella, but they show up again and again in local dealer quotes.

After twenty years around window sales, installation, and manufacturer reps, I’ve seen what happens when marketing claims meet real-world homes.
Alliance lands somewhere between “underrated workhorse” and “buyer-beware small manufacturer.”


Here’s the full picture so you can decide if they’re the right fit for your house.


Alliance Windows Quick Summary (2026)

  • Manufacturer: Alliance Window Systems – part of the American Window Alliance
  • Product Lines: Hawthorne (flagship), Belmont (premium), plus regional new-construction models
  • Price Range: $700 – $1,050 installed per window (typical)
  • Warranty: Limited lifetime – coverage varies by regional manufacturer
  • Best For: Homeowners wanting mid-tier vinyl performance and local service
  • Watch Out For: Small-manufacturer risk – warranty and parts support depend on the local factory
  • Comparable Brands: Gentek, Soft-Lite, Vinylmax, Andersen, Pella

Belmont windows reviews made by Alliance Window Systems

Who Makes Alliance Windows?

Alliance isn’t one giant corporation.
It’s a co-op of regional manufacturers that build windows under shared specifications from the American Window Alliance.
Your windows are made by the Alliance member closest to you.

That setup offers shorter lead times and a “buy local” story — but it also means warranty and service quality can differ from state to state.
A homeowner in Michigan and one in Georgia could own “Alliance Hawthorne” windows built by two different factories. The salesman may tell you this isn’t a problem, but it could be.


Alliance Window Product Lines

Hawthorne Series – The Flagship

The Hawthorne line is Alliance’s bread-and-butter double-hung replacement window. It checks the usual boxes: fusion-welded frames, dual weather seals, Low-E glass, argon gas fill, and a lifetime limited warranty.


Think of it as a solid middle-class vinyl window — practical, efficient, and widely available.

Belmont Series – The Upgrade

The Belmont series adds heavier reinforcement, optional foam fills, and triple-pane glass. It’s built for harsher climates and homeowners who plan to stay put.

You’ll see lower (better) U-factors and a broader color palette, but you’ll also pay a bit more.

Regional New-Construction Lines

Products like Prairie or WindowPro target builders, not replacement projects.
They use slimmer frames, fewer color options, and builder-grade hardware. In my experience lower end new construction windows are something to avoid.

For remodeling projects, Hawthorne or Belmont remain the smart picks.


Reviews of replacement windows from Alliance Window Systems

  • Hawthorne replacement windows
  • Belmont replacement windows
  • Replacement patio doors
Alliance Window Systems use the duracell spacer system in Mass.
It looks like the different manufacturers may be using different spacers to seal the glass. We found the manufacturer in Massachusetts showing a brochure with DuraSeal and the company in Chicago advertising InnovativeE.

Energy Performance and Efficiency

Alliance windows can meet or beat Energy Star standards if you choose the right glass package.
Typical numbers:

Glass TypeU-Factor ↓ is BetterSHGCNotes
Double-pane Low-E / argon≈ 0.29 – 0.300.27 – 0.30Standard package
Triple-pane Low-E / argon≈ 0.22 – 0.250.20 – 0.24Cold climate upgrade

Air infiltration ratings around 0.10 – 0.15 CFM are respectable for this price tier.
Just remember — the installer’s foam seal and caulking matter as much as the glass.

(External reference: Energy Star Certified Window Criteria)


What about the Alliance Window Systems warranty?

This business model has been tried before with mixed results. The biggest problem in the past has been the warranty. Customers will sometimes get the impression that the warranty is backed by this whole system of 6 or 7 manufacturers but in reality that’s not always the case.

Alliance Window Systems warranty

In the case of the Alliance Window Systems warranty, the warranty is only offered by the individual manufacturer who made your windows. That is listed in the written warranty. I’d say that’s not the best for the customer, but it does make sense for the business.

Warranty and Support

Alliance promotes a limited lifetime warranty for the original homeowner, covering frames, sashes, hardware, and IGU seal failures.
But each Alliance manufacturing member administers its own warranty.

What to check before you buy:

  • Is labor included for service calls or materials only?
  • Can the warranty transfer if you sell the home?
  • Who handles claims — your dealer or the factory?

If your local Alliance member ever closes, you’ll depend on another member’s goodwill for future service.


That’s the biggest variable in the whole equation.

(See BBB.org – Alliance Window Systems Regional Profiles)


Real-World Homeowner Feedback

Alliance windows generally earn 3½ to 4 stars out of 5 across review platforms.

Common positives:

  • Noticeable comfort and energy bill improvement.
  • Clean appearance and easy operation.
  • Appreciation for buying from local dealers.

Common negatives:

  • Seal failures within 5 – 8 years on some units.
  • Warranty response time depends on region.
  • Fewer design options than big brands like Pella.

Like any vinyl window, performance comes down to installation quality and dealer support.


On the Alliance website they talk about being a national operation, but they only list operations in a handful of states in the midwest and northeast. They’re not franchises. Rather they’re independent companies all making windows under the same brand.

Note Alliance Window Systems is not the same company as the bankrupt Alliance Vinyl Windows or Alliance Window Co, all with similar names but different companies.

Caption: Alliance Window Systems compared with Gentek, Andersen, Pella, Soft-Lite, VinylMax, and Window World for 2026 homeowners.


Alliance vs Andersen

  • Andersen’s Fibrex and wood-clad windows are a different animal.
  • They cost two to three times as much but offer superior fit, finish, and resale appeal.
  • Alliance wins on price; Andersen wins on design and longevity.

Pella vs Alliance

  • Pella sells style and branding.
  • If you want wood interiors or architectural detail, Pella is worth it.
  • For basic vinyl replacements, Alliance delivers similar energy performance for less.

Alliance vs Gentek

  • Gentek is one of the most underrated names in the industry.
  • Backed by Associated Materials, they have the corporate stability that Alliance lacks. If long-term warranty security matters most, Gentek wins.
  • If you want to buy local and save a bit, Alliance can still be a fair choice.

Alliance vs Soft-Lite

  • Soft-Lite outperforms Alliance on air leakage and thermal ratings but costs more.
  • If you’re chasing maximum efficiency, go Soft-Lite; for everyday value, Alliance works.

Vinylmax vs Alliance

  • Both target value-driven buyers.
  • Vinylmax has more unified manufacturing; Alliance leans on local factories.
  • Service will depend entirely on your dealer.

Alliance vs Window World

  • Window World is about price first, everything else second.
  • If budget rules, Window World wins.
  • If you care about materials and fit, Alliance is the better buy.

Pricing and Value

Expect to see quotes like:

  • Hawthorne: $700 – $950 installed
  • Belmont: $850 – $1,050 installed
  • New construction: $500 – $650 installed

Upgrades — triple-pane glass, foam fills, custom colors — add $100 – $200 per window.
That puts Alliance in the upper-middle of the vinyl market — cheaper than Andersen or Pella, but a step up from builder grade.

(External reference: NFRC Certified Product Directory)


The Small-Manufacturer Risk

Alliance’s decentralized model is its strength and its Achilles’ heel.
Every factory is independent. If one goes under, customers lose their warranty and access to matching parts.
I’ve watched dozens of respected small manufacturers disappear over the years, leaving homeowners with no recourse.

That’s why I often recommend choosing a window from a large, financially stable company like Gentek if you’re planning to stay in your home long-term.
It’s not about build quality — Alliance windows themselves are fine — it’s about the odds that someone will still answer the phone in 15 years.


Installation Matters More Than Brand

Even the best window can fail if installed poorly.
Look for dealers who detail their installation steps: foam insulation, flashing, shimming, and sealant.
Avoid “today only” discounts and quotes without scope details.

Pros and Cons Summary

Pros

  • Solid mid-range energy efficiency
  • Local manufacturing and support
  • Competitive pricing
  • Lifetime limited warranty (on paper)
  • Clean styling and custom sizes

Cons

  • Warranty and service vary by region
  • Inconsistent quality control across factories
  • Small-manufacturer risk if a member closes
  • Limited design upgrades
  • Labor not covered under manufacturer warranty

When Alliance Makes Sense

Good fit if you:

  • Want a fair-priced, American-made vinyl window.
  • Prefer local service and short lead times.
  • Plan to stay in the home 5–10 years.

Better to look elsewhere if you:

  • Expect long-term warranty support (> 15 years).
  • Live in harsh weather zones or coastal areas.
  • Want maximum energy efficiency and airtightness.
  • Are investing in a forever home and want corporate backing.

Final Verdict – Are Alliance Windows Worth It in 2026?

Yes — Alliance Windows offer solid value for the price, provided you understand what you’re buying.
The Hawthorne and Belmont lines are dependable vinyl windows that perform well when installed properly.
Just go in with open eyes about the small-manufacturer risk and make sure you’re working with a dealer that will stand behind the installation.

If you want rock-solid long-term security, brands like Gentek or Soft-Lite are safer bets.
If you want a good, locally made window at a reasonable price, Alliance can still be a smart choice.


Alliance Windows FAQs (2026)

Q: Are Alliance windows good quality?

Q: Who makes Alliance windows?
They’re produced by regional members of the American Window Alliance co-op, each manufacturing locally under shared specs.

Q: How much do Alliance windows cost installed?
Most homeowners pay $700–$1,050 per window installed depending on series, size, and options.

Q: What’s the biggest downside of Alliance windows?
Warranty and parts support depend on which regional factory made them. If that factory closes, coverage can be limited.

Q: What are some alternatives to Alliance windows?
Gentek and Soft-Lite for long-term security, VinylMax for regional value, or Andersen/Pella for design and brand prestige.


Why would you buy windows from Alliance Window Systems?

It’s important to remember that if you’re considering buying windows from a small manufacturer like this you’d want to be clear about why you think that’s a good choice. It’s inherently risky to work with a small manufacturer. Maybe there’s some reason you want to take that risk, but if there isn’t then I’d suggest working with a larger and more well established outfit.

That’s not because I don’t like Alliance Window Systems. It’s just because I’ve seen many small window manufacturers vanish. We’ve written many posts about many bankrupt companies. That’s a vary bad outcome for their customers.

I know the salesman will say they’ve been in business for so many years and his customers are all thrilled. That’s probably true, but it doesn’t make the risk go away. In my mind that’s not a good enough reason. You can certainly make your own choice.

Alliance Vinyl Windows Out of Business

If you’re looking for info on Alliance Vinyl windows I have some bad news. It looks like they’ve headed off into the distance and they are permanently closed.

It is important to note that this is Alliance Vinyl Windows Co, not Alliance Window Systems. Alliance Window Systems a network of small window manufacturers. Similar name, different operation.

The picture above shows the google listing we found for Alliance Vinyl Windows. A call to their phone number went to a recording saying the number was out of service.

What happened?

Unfortunately this can be a risk when dealing with the small window manufacturers out there. I know the in-home salespeople can tell a convincing story but there’s a real risk in working with these little manufacturers and I think that risk is often under appreciated.

I think the salespeople can get away with selling some of these products because most customers aren’t familiar with window manufacturers. You probably don’t know who is a worthwhile manufacturer and who is a little too risky. That’s a lack of information that the salespeople will exploit.

We can help.

Does it matter if you bought windows from a company that is now bankrupt?

Yes. Hopefully your windows work just fine and you won’t have any problems down the road. Unfortunately you now have no warranty at all. Worse than that there’s no access to spare parts. That can be the most challenging part.

What about my warranty from Alliance Vinyl Windows?

Unfortunately it’s gone. If you find yourself in this boat I wouldn’t get too worried about it. There’s nothing you can do anyway so worrying won’t help.

Some repairs can still be made. For example if you have a window break or if you get a seal failure in an Alliance Vinyl Window Co window a third party company can likely fix it.

You’d be paying out of pocket for that repair but it can be done easily enough.

If you have a problem that requires new parts like a new lock, a new screen frame or a new vinyl frame or sash the repair will be more difficult, or impossible.

In that situation you’ll likely be buying a new window from a different manufacturer. That’ll be the only solution.

Andersen Windows Sells Silver Line and American Craftsman brands

This is a deal that happened a little while back and at the request of some commenters who may be Renewal by Andersen salespeople we’ve posted it here.

We used to find it funny that the Renewal by Andersen salespeople would pick on vinyl windows while their company was producing thousands of them, but now they’ve sold these vinyl brands.

Why did Andersen sell these brands?

Maybe they took our advice that producing cheap vinyl windows didn’t help their sales pitch for more expensive options. Either way, below you’ll find the press release they issued back on August 28th.

Now that the American Craftsman and Silver Line window brands are owed by Ply-Gem windows we’ll see if there are any updates to the product lines. Ply Gem has a lot of experience producing vinyl windows so perhaps we’ll see some much needed upgrades.

Here’s their press release

BAYPORT, Minn., Aug. 28, 2018 /PRNewswire/ — Andersen Corporation, America’s premier window and door manufacturer, today announced that it has signed a definitive agreement to sell its hollow core vinyl window and patio door business, including the Silver Line and American Craftsman brands, to Ply Gem, a leading manufacturer of building products used in both new construction and home repair and remodeling across the United States and Canada. 

Andersen has been leading the window and door industry for more than 115 years by creating different and better products and services and building brands people value and trust. In recent years, the company has achieved unprecedented growth, driven by its Andersen®, Renewal by Andersen® and specialty brands. 

“This divestiture is part of Andersen’s broader strategy to sharpen our focus on our Andersen, Renewal by Andersen and specialty brands, continue to make the significant investments required to support our fast-growing, proprietary, Fibrex® engineered composite products, and deliver exceptional value to our customers for years to come,” said Andersen Corporation Chairman and CEO Jay Lund. “In addition, we believe the Silver Line and American Craftsman brands and the talented employees who have built these brands will have continued growth opportunities under Ply Gem’s stewardship.”

Ply Gem will acquire the four Silver Line manufacturing plants, associated distribution and support services for $190 million, which represents a 10X multiple of Silver Line’s trailing 12-month EBITDA through the second quarter of 2018. The more than 4,000 employees working in these locations and functions will transition to Ply Gem with the business.

“The Silver Line and American Craftsman brands are industry leading brands and have been trusted by customers and consumers for over 60 years and Ply Gem is excited to add them to our existing portfolio of quality window products,” said Gary E. Robinette, Ply Gem’s Chairman and CEO.

The transaction is expected to close by early in the fourth calendar quarter of 2018, subject to regulatory review and approval.

Vista Window Company Closes Their Doors

Unfortunately another smaller window manufacturer has closed their doors for good.  It looks like Vista Window Company is gone.  Their voicemail says they closed due to unforeseen circumstances and their google listing says they’re closed for good.  We always hate to see a company struggle.  Unfortunately, I think it’s going to continue to get more difficult for smaller window companies to compete.

What happens with the Vista Windows Warranty?

We’ve reached out to Vista Window Company and asked about the status of any pending orders and if there is any process for warranty claims as I’m sure our readers will be asking.

Right now, I would guess that there is no warranty and owners of these windows may be out of luck.  If we hear back with any info I’ll update this page right away.

What about pending orders for Vista Windows?

If you have an order pending for Vista windows I’d reach out to your contractor or dealer right away to make sure they can offer you something else.  Most reputable contractors will have credit terms established with manufacturers so they likely haven’t actually paid for your windows.  That means the contractor still has any deposit you’ve given them and you can (hopefully) order something else.  If they tell you the deposit is spent you might want to check with an attorney as you’ll probably have a hard time getting that money back.

If you hear any info that is different than what we’re written here please let us know asap.  You can post a comment or contact us privately.  I’m sure many folks will have questions about the status of Vista Window Company so any info you have to share will be helpful.

What if I was about to order Vista Windows?

Consider yourself lucky!  It’s time to order something else.  I’d look towards larger manufacturers.  You never know what the future may hold for any company, but there are plenty of large and we’ll established companies out there.  There’s no need to take a gamble on a smaller player.

If/when we receive any new information on Vista Windows we’ll post it on this page so feel free to bookmark this page and check back for updates anytime.

What to look for in a Window Warranty

Replacement Window Warranty Factors

When shopping for replacement windows, one of the majors factors that folks consider is the window warranty.  The warranty coverage on your new windows is significant for many reasons, not the least of which is that you want some security in knowing that you will have long term support on a purchase of thousands of dollars. Like many things in the marketplace, window warranties are part real concern, and part sales and marketing. I like to break warranties down to two primary areas: Product Warranty and Installation/Workmanship Warranty.

Product Warranty:

The product warranty on a replacement window is exactly that. It is the length of time that a manufacturer will provide warranty coverage for manufacturer defects. Generally that will not include items such as damage from abuse, failure to maintain, etc.  However, it does provide for replacement parts should anything fail due to a manufacturer defect. Common items include failed glass seals in an insulated glass unit, defective hardware, warpage, etc.  Some manufacturers offer accidental glass breakage as part of their coverage as well. Most vinyl window manufacturers offer a lifetime warranty, while wood windows generally have some variation of a 20/10 warranty, meaning 20 years on glass and 10 years on everything else including the wood.

Things to watch for:

Transferability  is important if you are considering selling the home any time soon. This means that you will be able to transfer the product warranty to one or more future owners of the home. Proration is an often overlooked factor. “Prorated” means that while there is coverage for the entire warranty term, it goes down over time. This is similar to a car battery or roofing shingle, where you have 100% coverage for say the first 10 years, then the coverage starts dropping in increments where you are paying an increasing portion of that as time goes on.  Ideally, a warranty that is fully transferrable and not prorated is best.

What product warranties typically do not cover:

Abuse, acts of God (ie: fires, storms, etc. that would be covered be homeowner’s insurance). Product warranties typically will not cover any labor needed to install the replacements parts. That falls on you as the homeowner, or on the installation company if they offer that service, whether it be paid or at no charge to you. The “fail to maintain” provision can be tricky on wood windows where condensation can damage or rot the wood before the 10 years and potentially be denied as a claim.

Workmanship/Labor/Installation Warranty:

The installation warranty on your replacement windows while important, can vary wildly from one dealer to the next. One company may offer one year on workmanship/installation, while the next offers lifetime, and a third still somewhere in between. The fact of the matter is that most installation related issues will manifest themselves visually within the first year or two after install, so something like a 5 or 10 year warranty is generally adequate. That said, many companies offer 20+ years all the way through lifetime. A lifetime workmanship warranty may sound great in marketing, but remember that the installation warranty is only as good as the company offering it. If all else is equal, certainly a longer term only benefits you as a consumer.

Things to watch for:

Service call/diagnosis charges, coverage to install the parts that are provided under the manufacturer’s warranty and for how long, a list of items that are included or excluded.

What installation warranties typically do not cover:

Installation warranties are intended to cover any poor or defective installation practices. Therefore common things that would be considered maintenance items like caulking, cleaning tracks and such which could hinder operation, etc., are typically not covered or the coverage is limited.

BOTTOM LINE:

Every window warranty is not created equal. “Lifetime warranty” whether on product or installation may not mean the same thing from one company to the next, so take a look at the details and make sure that you are getting the protection that you are expecting. Also keep in mind that those warranties are only as strong as the companies offering them. Company history and reputation are important tools to look at. Lastly, “Lifetime” does have a quantifiable definition in most states. Here in Wisconsin, “Lifetime” for warranty purposes is defined as 30 years. It is recommended that you determine how this is specifically defined in your own location.

Single Hung vs Double Hung Windows

Here’s a little bit of terminology that is often misunderstood.  What are the differences between single hung vs double hung windows?  Here we’ll take a look at the basic definition and we’ll look at some of the other advantages and disadvantages including the cost, the operation, the screens, how they function and the typical price.

best replacement windows of 2015

First things first!  The basic definition:

Both single hung and double hung windows open up and down.  The difference is that in a single hung window the bottom sash opens up and down, but the top does not move.

In a double hung window the bottom sash slides up and down AND the top sash also opens and closes.

Perhaps this picture will help:

Here is the difference between a single hung and a double hung window.

So there it is, the difference is in how the window operates.  People often confuse double hung with double pane.  For the difference between double pane and triple pane windows check this out.

Ok, so how important is this difference?

Well, that’s really up to you.  One important thing to keep in mind is that a single hung window does not allow the top sash to tilt in for easy cleaning.  That means the bottom will tilt in, but the top will not.  Is that a big deal?  Only you can decide.

Beyond that many people don’t open the top very often so the difference is not important to them.  We open the top quite a bit in my house as the window dog is a redbone coonhound from the hills of West Virginia and he would go straight through a screen if he saw a varmint in the yard.  For us it is very important that the top opens, but you may have different priorities.

What is the price difference between single hung vs double hung windows?

This is a question we get asked a lot.  The difference typically isn’t huge, but it can add up.  The two windows are essentially the same with the single hung having less hardware.  The cost difference between the two will depend on the manufacturer, but it wouldn’t be uncommon to see a price difference of $20-$40 per window.

If you have 20 windows in your house that amount can add up.  We’ll often suggest switching to single hung windows as a way to save a few bucks, but it really just depends on how you plan on using them.
