Requesting free quotes from multiple providers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first step when planning a window replacement is to figure out whether you want a full-frame or pocket installation.

Full-frame installations are usually recommended when you want a new style or your window has a lot of deterioration. With this service, your installers will replace the total window, including the frame, sill and trim. Pocket installations are simpler and won’t cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re still trying to decide which kind of installation you need, you can consult with your installer and get their advice. The decision mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Lancaster

The EcoWatch Reviews team is different from most reviewers since we assess these companies through a sustainability lens. We’ve evaluated the best window installation companies in Lancaster mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Lancaster, we only included companies that cover the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Lancaster.

Work Quality

When it comes to 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 choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don’t have good feedback about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window companies may not provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
