Okna windows, do they live up to the hype, are they worth the cost? Let’s find out.
Generally speaking Okna windows is a relatively small manufacturer based in PA. They produce a range of vinyl replacement windows for residential use.
Some in-home window salespeople may make claims that aren’t backed up by reality but that’s not Okna’s fault. Let’s get down to it. Manufacturer site: oknawindows.com

Okna windows reviews:
Okna 400 Series windows also called Precision Weld
It’s important to note that Okna is a pretty small company as far as vinyl window manufacturers go. Small companies in this arena don’t always fare very well as our old friends at Gorell Windows found out.
Unfortunately, window manufacturing requires relatively high fixed costs to support the operations, machinery and management of a window plant. This cost structure combined with the financing costs typically associated with such a business makes these smaller manufacturers vulnerable when faced with a slowdown in sales or gross profit. We don’t know anything about Okna’s finances as they’re a private company, but this is generally the case with any smaller manufacturer.
Okna windows has also been involved in some questionable marketing in the past which may or may not be relevant to todays window shoppers. They settled a class action lawsuit that was brought by over 1000 angry customers in New Jersey just a few years ago.
The lawsuit stemmed from the fact that there were false marketing claims made during the sales process. One of their largest dealers went bankrupt as a result and all of those homeowners spent time and energy on the matter. This is settled and behind them now, but it is probably worth considering.

We know our readers in St Louis are looking for great windows installed by a great company which is why I’m happy to recommend my friend my friends Dennis and Rhonda, the owners of Zen Windows in St Louis.

Dennis and Rhonda will be publishing guest posts as their company has become a supporter of our site and they’re working hard to make the window business easy for folks in St Louis.
How did they get into the window business?
Glad you asked! Both of them have been in the home building and remodeling business in St Louis for years. Of course neither of them like being on the either end of the high pressure sales process so when they heard about the Zen Windows business model they knew it was a great fit for them.
Luckily for all of you in St Louis the business is booming and they’re making the process of buying new windows absolutely as easy as possible.
How do they make the process easy?
They do many things differently than a traditional window company. For one, they don’t need to come to your house and camp out in your living room to get you a detailed quote for your project. You can send them and email or give them a ring and they’ll explain how things work. It’s really easy.
What areas do they service?

The Andersen 400 Series windows are not great. Let’s find out why.
These are windows we installed for a good friend of mine. He picked them out and was sure that these were the windows for him. Shortly after they were installed he painted them himself and they sure do look pretty. When writing this review of Andersen 400 series windows I will be including pictures, pricing information and specific details.
What are the advantages of Andersen 400 Series windows?
For starters the Andersen 400 series windows look great. They look like nice wood windows. Once they’re painted to match the interior trim they certainly do look like part of the house rather than something that was installed after the house was built (you can just ignore the interesting paint colors that were picked on this project).
Next, another positive attribute of the Andersen 400 series is the tilt latch mechanisms. The sashes tilt in for easy cleaning like many new windows do these days. The way they operate is a little unique. Andersen has skipped the typical tilt latches on the meeting rail and opted for nearly invisible plastic clips that release the sash. This is a design that is also seen on other Andersen windows and it is very effective.
This is the mechanism that releases the sash on these Andersen 400 series windows
As you can see in the picture, all you do is slide the plastic clips down to the top of the sash and pull it in. This is a neat feature of the Andersen 400 series tilt-wash double hung model. You don’t find this mechanism from any other manufacturers.
What about the top sash?
The top sash, shown above, is even easier. It has the more traditional tilt latch mechanism on the top of the top sash. They do it this way because these latches are invisible when the window is closed.
These mechanisms give the window the ability to tilt in while maintaining the traditional look of a wood window. Perhaps it’s a small detail, but it does make the window look great and operate well.
The exterior of this Andersen 400 series window is vinyl clad and the exterior trim has been capped as you can see here. This leaves the exterior completely finished and maintenance free. Some folks prefer the look of wood brickmould or exterior trim and that would be an option, but it would then require painting. This homeowner wanted to go maintenance free and he achieved his desired result.
What are the downsides?
After living with these windows for a while some less than positive attributes of the Andersen 400 series have come into focus as well. For example, it’s clear that the owner ordered these windows unfinished and painted them himself. That means you can see areas where he was not able to get the brush. To get it perfectly finished he’ll need to go back and repaint all of these windows to get them looking great and that’s a chore.
Next, you can see the interior grids on these windows. They are flimsy and they bend when you try to pull down the top sash. We opened the windows from the top to get a picture of the tilt latch and we almost broke one. There is no other way to lower the top sash which means at least some will likely break in the future. This design alone is a serious shortcoming.
Last and certainly not least, these windows are drafty! When I was sitting on the couch during a winter storm sorting through the pictures to make sure I had everything I needed. I could feel cold air on the back of my neck coming from the window behind me. I pulled up the air infiltration ratings for this model and they say it’s <0.30. We know from the previous post on air infiltration ratings that this is pretty weak.
To sum it all up: this is a nice looking window. The specifics of the windows installed in this house are just details. For example the flimsy looking interior only grids are an option and you could order another type.
What about the air infiltration of Andersen 400 series windows?
The air infiltration on the other hand is a real problem. These windows are drafty and there is no way to change that. You don’t want to spend thousands of dollars for new windows to have a cold family and these windows just don’t provide a good seal. After observing these windows for a few months I can’t recommend them. Our good friend will be replacing these relatively new wood windows with another model that gets a much tighter seal.
The Andersen 400 series windows look great, but they do not seal well. If your goal was to look pretty with no concern for anything else then go for it. Most folks want a balance of beauty and efficiency. This window does not accomplish that goal.

Do not buy Pella windows for a replacement project. They’re just not a good choice.
Most folks only know the names of a few window manufacturers and Pella is typically one of them. Does that mean that Pella windows are any better than any other windows. No, it really doesn’t, but it doesn’t mean they’re any worse either. Manufacturer’s site: pella.com
Pella Windows 2025 Scores:
Quality: 71
Efficiency: 80
Options: 77
Warranty: 94*
Price: 64
Overall: 70 C-
Explanations of scores are shown below. Post a comment at the end to let us know if you agree or disagree with these ratings. We use this feedback to inform future ratings.
We recently wrote a post about Pella window complaints that you might also find interesting.
As you read through our Pella windows reviews keep in mind that a large company like Pella makes many options. They make cheap windows and they make nice windows. Sometimes we meet folks who had cheap Pella new construction vinyl windows in their home when it was built and they’re sure that all Pella windows are junk. Then we’ll meet people who had high quality Pella windows for 30 years and they’ll think Pella is the greatest company out there. In reality, both of them are wrong.
Pella doesn’t produce the best or the worst replacement windows available today, but they do have some interesting options. As you might expect they produce vinyl, wood and fiberglass options.
Pella Windows 2025 Scores:
Quality: 71
Pella windows get a 71 quality score from us partly because they’re sold through box stores. We’ve seen a lot of negative feedback from customers who ordered windows through a Home Depot or Lowes type of store. The quality just isn’t there sometimes and it hurts everyone.
Efficiency: 80
Overall the efficiency offered by Pella windows is decent but not remarkable. We’re not aware of anything unique or special that they offer in terms of efficiency. Air infiltration rates can also be slightly lower than what you’ll see from other companies. Overall the efficiency is fine, but not remarkable.
Options: 77
We’re just looking at replacement windows here and the options from Pella are a little limited. One might say this score is low and a decent argument could be made. Their new construction windows offer a very wide range of choices, but in terms of typical replacement windows we don’t find the options too exciting.
Warranty: 94*
We give the Pella window warranty great marks with an asterisks. It’s critical that you read and understand the actual warranty when you buy the windows. I know some salesman made some promise but he’ll be working somewhere else in 15 years when you have a problem with your windows. The warranty is solid but it doesn’t cover promises made by a commission based salesman.
Price: 64
The prices for Pella replacement windows like the Pella 250 are often not so great. It feels a little like they’re trading on their well known name and really trying to charge a premium. Whether you’re buying from a Pella store or a hardware store, in our experience you can often find a better value.

Overall: 70 C-
Pella gets a C- for our 2025 score but it’s not because the products are horrible. Overall the windows are decent and the efficiency is typical. The problem is that the value isn’t necessarily there because the prices are high and the products aren’t really special enough to justify the cost. New construction can be a different story, but we’re talking about replacement windows here.

Pella 350 Series- My favorite Pella option, now discontinued.
If you take one thing away from these Pella window reviews we hope it’s the fact that no company out there is either always great or always horrible. Just like every other company Pella makes options and the local company selling and installing the windows will have a very large impact on your overall experience.
It is the local installation company, not Pella, who sets the sale price, performs the installation, and provides follow up service. We hear about local installation companies all over the country who try very hard to trade on the Pella windows name. They try to charge a premium for the lower end windows because consumers know the name. Don’t be one of the people who fall for those tricks.
What should you avoid doing when shopping for new windows?
I tend to suggest you should avoid thinking that the only good windows are window brands that you’ve heard of before. for most people Pella, Andersen and Marvin are the only window manufacturers that they’re familiar with.
That means those companies tend to spend more money on advertising than their competitors. It doesn’t necessarily mean they’re the best options available.

If you’re researching Simonton Windows for your home in 2025, you’re in the right place. This review breaks down Simonton’s quality, efficiency, warranty, price, and performance.
Simonton has been a mainstay in the replacement window industry for decades, and they continue to hold their spot in the mid-range tier — not the cheapest option out there, but not top-of-the-line either. If you’ve ever walked into a Home Depot and seen Simonton displays, you already know how widely available they are.
Let’s dig in and see whether these windows still hold up in 2025.

A dependable mid-range window for homeowners on a budget
Bottom Line: Simonton makes dependable vinyl replacement windows with fair pricing, a strong warranty, and solid energy performance. They aren’t fancy, but they get the job done for most homeowners.
🪟 Who Is Simonton Windows?
Simonton has been building windows since the 1940s and remains one of the most recognized vinyl window brands in America. They focus on affordable, efficient, and practical replacement windows that are available nationwide through Home Depot, contractor networks, and regional distributors.
They are part of Cornerstone Building Brands, one of the largest building material companies in North America. That’s important — it means Simonton has backing and stability behind its warranty and manufacturing operations.
You can visit their manufacturer website here: simonton.com
⚙️ Simonton’s Window Lines and Models
Simonton produces a wide lineup, covering both replacement and new construction windows.
🔹 Replacement Window Lines
Reflections 5500: A popular flagship model with multiple glass packages.
Impressions 9800: More upscale, featuring thicker vinyl walls and stylish hardware.
Asure: A slim-frame, budget-friendly model for affordability.
StormBreaker Plus: Designed for hurricane zones and high-wind regions.
💡 Note: Not every Simonton model is available everywhere. Distribution varies by region, so your local Home Depot or contractor may only carry certain series.
🧱 Quality – Score: 80/100
Let’s be clear — Simonton makes solid windows, but they’re not built to compete with the high-end crowd.
You might see small cosmetic flaws (vinyl weld marks, minor inconsistencies) that you won’t find on brands like ProVia or Gentek. But the structural integrity and functionality are dependable. For the price, they hold up well over time — assuming proper installation.
Most quality issues homeowners report stem not from manufacturing, but from improper installation by smaller dealers. Always make sure your installer is certified and reputable — and not just “a guy with a truck.”
🌡️ Energy Efficiency – Score: 83/100
Simonton’s ProSolar glass packages offer respectable thermal performance and are ENERGY STAR® qualified in most configurations.
Their efficiency options include:
Low-E glass coatings to reflect infrared heat
Argon gas-filled IGUs (insulated glass units)
Warm-edge spacers to reduce condensation and energy loss
Where Simonton falls slightly short is in air infiltration performance. Their frame designs are a bit older compared to brands like ProVia Endure or Revere Berkshire Elite, meaning they may let in slightly more air under pressure testing.
That said, most homeowners will still see solid comfort and lower utility bills — especially if upgrading from single-pane or aluminum windows.
🎨 Options and Customization – Score: 72/100
Customization is where Simonton plays it safe.
You’ll find:
A limited palette of exterior colors
Standard hardware finishes
A few decorative glass and grid patterns
It’s enough for most projects but not ideal if you want architectural or design flexibility.
If you want interior woodgrain, custom colors, or decorative glass, you’ll find more variety from Gentek or ProVia.
🧾 Warranty – Score: 90/100
Simonton offers one of the better limited lifetime warranties in the mid-range category.
It typically covers:
Vinyl frames and sash
Hardware
Glass seal failures
The warranty can usually be transferred once to a new homeowner, which adds resale value.
Just remember that labor and installation coverage comes from your dealer — not Simonton — so always get those terms in writing.
Simonton’s pricing has remained consistently competitive.
In 2025, expect to pay approximately:
$550–$950 per installed window, depending on model and region
DIYers may find some models at $350–$600 through Home Depot
Price variation often depends more on dealer markup than manufacturing cost. Smaller local installers sometimes inflate quotes or bundle labor and upgrades into vague “package deals.”
We recommend asking for an itemized quote showing:
Window series and model
Glass package
Frame color and options
Installation cost
That transparency makes it much easier to compare your Simonton quote to alternatives from ProVia, Soft-Lite, or Gentek.

🧠 Final Verdict: Are Simonton Windows Worth It in 2025?
If you’re looking for a solid, dependable, mid-priced vinyl window, Simonton is still a smart pick in 2025.
They’re readily available, backed by a strong warranty, and built by a company that’s likely to be around for decades.
However, if you want maximum efficiency, premium finishes, or cutting-edge performance, you’ll find better options with ProVia, Gentek, Soft-Lite or Sunrise.
In short: ✅ Great for affordability, reliability, and wide availability. ❌ Not ideal for premium builds or design-heavy renovations.

If you’re comparing Alside replacement windows to the rest of the field in 2025, you’re probably seeing a lot of marketing and not a lot of straight answers. This review cuts through the noise. We’ll cover actual installed prices, which Alside models are worth considering, how the warranty really works, common complaints, and how Alside stacks up to ProVia, Simonton, and Gentek.
Quick reminder: Alside is a long-running vinyl window brand under Associated Materials (AMI), which also includes the higher end Gentek and Preservation brands and several other lines. That corporate backbone matters for warranty support and parts availability over time.
Quick Verdict
Alside makes solid mid-tier vinyl windows with broad availability and fair pricing. If you want dependable, no-drama replacement windows and you’re shopping on value, Mezzo is typically the sweet spot. If you’re expecting premium fiberglass performance or luxury fit/finish, look at higher-end vinyl or fiberglass.

Who Makes Alside Windows?
Alside is part of Associated Materials, LLC (AMI), a large North American manufacturer and distributor of exterior building products. AMI’s scale helps with distribution, parts, and warranty continuity—key differences versus small regional brands. You can read more on Alside’s site or AMI’s corporate pages if you like, but the short version is: Alside is a stable, mainstream choice backed by a big manufacturer.
Official site: alside.com Certifications database: nfrc.org (search specific models for ratings)
Build Quality & Materials (What You’ll Notice at Home)
Alside windows are vinyl, not fiberglass or composite. That sets realistic expectations:
Hardware: reliable, not flashy; smooth enough when installed correctly
Weatherstripping: standard vinyl-class seals; choose better glass to push efficiency
Aesthetics: narrower profiles on the better lines (e.g., Mezzo), cleaner welds, acceptable sightlines
Bottom line: they’re built to hit a price point and hold up reasonably well. As with all vinyl, installation quality is the make-or-break factor for longevity and drafts.
Energy Efficiency & 2025 Tax Credit (Still Time)
With the right configuration (Low-E coatings, argon fill, warm-edge spacer), most Alside models meet ENERGY STAR® in every U.S. region. That matters because the Federal Energy Efficient Home Improvement Credit (25C) in 2025 still offers up to 30% back (max $600 per year) for qualifying window upgrades. To be safe, confirm the exact NFRC ratings on your quote match your climate zone requirements.
If you want deep color palettes, wood-look interiors, or designer hardware, you may be happier with a premium vinyl or fiberglass line. If you want clean, simple, and affordable, Alside’s options make sense.
Warranty (What’s Actually Covered)
Alside typically includes a limited lifetime warranty on vinyl frame/sash for the original owner, with specific terms for:
Insulated glass seal failure (defined years)
Hardware (defined years)
Transferability (often limited and time-bound)
Labor (usually excluded—comes from your installer)
Tip: Ask your dealer to provide the exact written warranty for your model before you sign. Don’t assume glass breakage or on-site labor are included (they usually aren’t).
Common Complaints (and What They Mean)
You’ll see these themes in homeowner feedback across most vinyl brands, Alside included:
Seal Failure / Fogging (years down the road) Happens with many insulated glass windows over time. Choosing a reputable installer and proper glass package helps minimize risk.
Sash Sag / Warping More common in large units or in homes with big temperature swings. Proper shimming and reinforcement make a difference.
Air Infiltration Entry-level models and sloppy installs can draft. Always ask for the air infiltration (AI) rating and upgrade if yours is high.
Service Delays Warranty parts come through Alside/AMI, but scheduling is dealer-dependent. Ask your dealer about their average service turnaround.
None of these are deal-breakers, but they reinforce the biggest lesson in windows: a great installer + clear specs beats brand hype every time.
Alside vs ProVia, Simonton & Gentek (2025)
Alside vs ProVia (Endure)
Price: Alside usually costs less installed.
Performance: ProVia Endure often posts lower air-infiltration and more robust options.
Finishes: ProVia wins on color/laminate and hardware selection.
Verdict: If budget is tight, Alside is fine. If you’ll live with these windows for 20+ years and want a more refined product, ProVia Endure is often worth the upgrade. Read: https://thewindowdog.com/provia-windows-review/
Alside vs Simonton (Reflections / 5500)
Price: Similar; Alside sometimes cheaper due to promotions.
Availability: Both widely available through dealers; Simonton also shows up in big-box channels.
Performance: Very comparable mid-tier vinyl. Edge goes to whichever quote is itemized, has better AI rating, and comes from the better installer. Read: https://thewindowdog.com/simonton-windows-review/
Verdict: While there are some similarities, the Gentek Signature Elite will be a higher end product with better components and is often offered by more professional dealers. The Alside Mezzo line is a fine choice, but a step down from the Gentek option. Read: https://thewindowdog.com/gentek-signature-elite-review/
How to Shop Alside the Smart Way (and Avoid Sales Tricks)
Insist on itemized quotes. Model, glass package, color, grids, capping, disposal—line by line.
Ignore “today-only” pricing. If they can sell it today, they can sell it next week.
Ask for ratings in writing. U-factor, SHGC, and air infiltration (rarely volunteered).
Verify tax-credit eligibility before signing. The wrong glass combo can knock you out.
Choose the installer first. A great installer with Alside beats a mediocre installer with any “premium” brand.
FAQs: Alside Replacement Windows (2025)
Are Alside windows good? Yes. They’re good mid-tier vinyl windows. Not luxury, not junk—fair value when installed well.
How much do Alside windows cost in 2025? $500–$1,400 installed per window depending on model, size, glass, and region. Mezzo typically lands $600–$1,000.
Which Alside model is best? For most projects, Mezzo balances price, efficiency, and appearance well. See our full Alside Mezzo review: https://thewindowdog.com/alside-mezzo-review/
Do Alside windows qualify for the 2025 tax credit? They can—if the specific configuration meets ENERGY STAR for your zone. Confirm NFRC values on your quote.
What about the warranty? Limited lifetime on vinyl, with defined terms on glass/hardware. Labor is usually not included—that’s your installer.
Alside vs ProVia—who wins? ProVia Endure is more refined, but it costs more. Alside wins on price/availability.
Find the Best Window Companies (Nationwide)
If you’re considering Alside—or weighing options like ProVia, Simonton, or Gentek—the best first step is picking a great company to work with. We maintain a list of recommended window companies across the country that offer transparent pricing and no pressure.
We’ve been helping homeowners navigate window replacements since 2012, and we take accuracy seriously. If you see anything here that looks off or outdated, send us the specifics (with documentation if possible) and we’ll review and update promptly.
What if I don’t see an Alside window model listed here?
The 8000 or 9000 series windows are often sold under “private label” programs offered by contractors across the country. Many times these contractors will claim to produce the window themselves or they will claim that it was specifically produced for them. In reality this is a window that has been produced by Alside for years. So, if the contractor lied to you about making these windows you should probably look elsewhere.
The Alside 8000 and 9000 series windows have some drawbacks. If any company is showing you a product with a model number that starts with 8xxx it would be from this family. If they’re using some funny model name just ask them for the model number and we can help to show you what it actually is. Model numbers that are in the 8000 or 9000 range (Preservation windows) likely will not be the best options.

As you can see Alpine windows only currently produces one line of replacement windows and two lines of new construction windows. This makes understanding the options much easier than it is with many manufacturers. The 70 and 80 series are designed for new construction. The Montrose line is designed for remodeling projects along with the Westbridge 6500 sliding patio doors.
Do Alpine windows qualify for the federal tax credits?
Yes, maybe. Alpine offers efficient glass packages that do qualify for the federal tax credits for energy efficient windows and doors. All options do not quality.
If you’re interested in this you’ll want to talk to the dealer or installer to make sure the option you’re ordering will qualify. These options do come with additional costs which may cost more than the tax credit you’ll get, but you also get very efficient windows.
The qualifying packages are called SolarTherm PriME. Despite their ridiculous capitalization they are very efficient packages.
What is the warranty from Alpine Windows?
The warranty is pretty solid and that’s one of the strong points for this brand. These windows come with a lifetime warranty that is backed by a billion dollar company with a 70+ year history in the building products business.
The warranty includes lifetime coverage for the windows and the labor required to repair a problem. That’s pretty good, better than the warranty you’ll see from some other companies.
One problem we’ve heard about affects people who bought windows from Alpine before they were purchased by Associated Materials. Customers from the old days have had trouble with their warranty claims. If your windows are 15+ years old you may be in that boat. In my experience that will only impact customers who bought windows before the company was acquired by Associated Materials which was around 2003 give or take.
Be sure to let us know how it goes. We’re especially interested to hear from you if your warranty claim was denied. Let us know how the windows failed and what the folks at Alpine said about it.
Why order Alpine windows?
One real advantage is that they’re now backed by a billion dollar manufacturing company. When you’re purchasing products with a long-term warranty it’s important to consider the financial strength of the company itself. In recent years we’ve seen many small regional manufacturers go under leaving all of their past customer with no warranty at all. Examples of this include Gorell windows, Kensington Windows, Republic Windows and more.
Many of these little window companies can look great in a brochure, but they’re not so great in real life. In my opinion people routinely undervalue the risk associated with a little manufacturer which is why it’s always my recommendation to work with a larger and more well established company.
You can be relatively confident that a large company like Associated Materials will be around for the long haul which will be important if you ever need to use your warranty.
Overall these windows are decent. Like most manufacturers they make cheaper new construction windows and nicer replacement windows. The Montrose line is a solid choice for a replacement window with a solid warranty.
Remember, before you fall in love with a window manufacturer you should find a good local dealer who can help to make recommendations.
We commonly see people put the cart before the horse by deciding which window model they want before they find someone to install it. This is understandable, but it’s not a good strategy.
It’s possible that the product you’ve decided you love is only offered in your area by someone you don’t want to work with. In that case you’ll be frustrated, I guarantee it.
Your best bet is to find a great local company and talk to them about what they recommend. You can find our listing of great local replacement window companies here.
