Install & Repair Windows

So you want to install replacement windows on your own?  That is certainly an option.  The process is relatively straightforward, but there are several factors you should consider when deciding to install replacement windows.

We’ll discuss several factors including:

  • Evaluating the project before you commit
  • How to measure replacement windows
  • How to measure sliding patio doors
  • How to order replacement windows
  • Selecting replacement window options
  • Typical cost of replacement windows
  • Removing old wood windows
  • Removing old metal windows
  • Removing old vinyl windows
  • Removing sliding patio doors
  • Using foam insulation around the new windows
  • Installing windows into a wood frame
  • Installing windows into a drywall pocket
  • Installing sliding patio doors
  • Will your old blinds fit with your new windows?
  • Capping or exterior trim
  • Finishing details & adjustments
  • Replacement window warranty and manufacturer service

Some people think they’re going to save a fortune when they install replacement windows on their own.  The amount of money you may save on your project very much depends on how you value your time.  There is also a certain personal satisfaction that comes from completing a home improvement project and that has value as well.

It is not uncommon to find a solid company that will install efficient vinyl windows for around $300-$400 per window.  On your own you can probably purchase custom made energy efficient vinyl windows at a cost of $200-$300 so there certainly are savings to be had.  Replacement window prices can vary quite a bit, but you’ll find prices are often not directly related to quality.

When considering the options remember that a professional installation team can install 10-20 windows in a day complete with caulking and exterior trim or capping.  A typical do it yourself project will be much slower.

If your expected cost savings is about $100 per window, you can only install 2 windows per day and you only have time for the project on the weekends, you would take 5 weeks and 5 consecutive weekends to install 20 windows.  In addition you probably don’t have the equipment to install the exterior trim or capping.  WIth some bad weather or other delays the project could easily take 2 months.  A professional team could knock that project out in a day or two and you can spend your weekends on something else.

Should you install replacement windows on your own?  That’s completely up to you.  If you decide to go for it, we’ll be glad to help out.  Keep an eye on the posts linked above.  We’ll continue to add more information along with pictures and descriptions.  If you have any questions or if you’d like any more info just let us know.

    I just had a Sunrise Vanguard sliding window installed in my bedroom. It was so hard to open till they sprayed a silicone material onto the bottom of the window. Is that normal for a new window to be so hard to open?

      Hi Larry, it could be a sign of a problem, but it might not be an issue at all. The worst case scenario would be that the sash is a little too big for the frame or that the window was measured a little big and forced into the opening. Those could present longer term problems. So, I’d keep an eye on it over the next month or two. If the windows work fine 90 days from now I’d say there’s probably no issue. If they become harder to open over time I’d touch base with Sunrise and with the dealer to make sure there’s documentation of the issue. Don’t want 3 or 4 years to think about it again because by that point they probably won’t want to deal with it at all.

    I have many windows that are failing with seals and other issues. The house is 2006 and has new construction windows with flanges installed. How would you use replacement windows to ensure there is a watertight seal or would you need to use new construction windows again? The house is vinyl siding. Some companies have said they would remove the frame but cutting the flanges and leaving them in place and then flashing to the old flanges. Curious for your input.

      There are two ways to replace windows like that. You can cut the flanges, remove the old frame and install a replacement window. Or, you can remove the exterior trim, remove the flanges and install a new construction window with new flanges. It’s more common to use a replacement window. Doing it that way doesn’t require new exterior and interior trim and many thousands of windows are installed that way every single day. Typically I’d recommend a replacement window. If you happen to also be replacing the siding and you want to replace interior trim and sills as well you could use a new construction window with a nail flange.

      In my experience the end result is basically about the same either way so no need to incur all of the additional costs of trying to use a new construction window in a replacement project.

    I have to replace an Andersen hopper type window (model 2817?). This will be a job I do myself having replaced several windows throughout my home. The sill is rotted as concrete for a walk was poured up to and covering the face of the sill. A vinyl replacement is the way to go.
    I’ve read the reviews on your site for the vinyl windows at HD and Lowes and am not overly impressed. Our local lumberyard stocks Duo-Corp Aristoclass hopper windows. I didn’t see them on your list of companies and wondered if you had any experience with these windows. Any other suggestions would be appreciated.
    Thank you.

      Hi Tom, I haven’t dealt with Duo-Corp windows so I’m not much help there. Where are you located? I might be able to make a recommendation.
