What Services do Window Installers Offer?

The first question to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?

A full-frame installation is a replacement of the full window. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.

If you’re still trying to decide which kind of installation to get, you can talk to your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage present.

We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including cost, quality of installation, professionalism, warranty, quality of parts and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a sizable investment, so you’ll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
