The Window Source Installation Process

What to expect on your window installation day

Many of the homeowners we work with don’t fully understand how simple window installations can be. The thought of having your windows replaced can be a bit overwhelming if you don’t understand the process, so we want to hear your concerns and answer your questions.

Common questions that you might have:

We want our customers to be fully informed on what to expect from the installation process. These are a few of the most common questions we get from customers before they pull the trigger on replacement windows.

  • Will my interior window trim be damaged or need to be replaced?
  • Are my window blinds still going to fit with new windows?
  • Will the installation process take days or even weeks to complete?
  • How much is the installation going to cost me?
  • How long will it take to get my windows installed after placing my order?


A good quality installation is just as important as a quality window. It starts with an accurate measurement and ordering the properly sized replacement window to allow for a good fit with enough tolerance to plumb and square the new window in place.


After your window consultant inspects and measures your openings, your new windows are custom manufactured for a precise fit. Before leaving our state of the art manufacturing facility your new windows are inspected to insure your complete satisfaction. All units leave the plant with an NFRC label attached so that you can verify the performance of you new windows.

New windows are ready to be put in place

The installation crew will make sure the window opening is clean and clear of any debris. Next, your new vinyl double-hung windows will be installed in the existing opening and checked for proper alignment. The window will be plumb, level, and square while fastening the window to the frame. The window will be tested to make sure it is operating correctly. Finally, the window stop will be reinstalled to its original position and caulked for an airtight seal. The installation crew will make sure the window has been insulated on the exterior of the home also.

That’s it!

Our installation crew will do a walk through with you to make sure you are 100% satisfied with the job that has been completed. The installers will not leave the job site until you sign off that you are completely satisfied with the installation and product.
