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?

Full-frame installations entail replacing the total window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has significant damage. Because these installations are more involved, they will increase the total cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re still trying to decide which kind of installation you need, you can talk to your provider and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Waukesha

EcoWatch reviews differ from other reviews since we examine these companies through a sustainability lens. We have decided to assess the best window installers in Waukesha mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Waukesha, we paid more attention to companies that serve the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Waukesha.

Work Quality

When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

This one is a give-and-take: similar to most services, cheap window installers may not provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a wide range 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 be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
