What Services do Window Installers Offer?

When it comes to window replacements, there are generally two kinds that your provider will offer: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which increase 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 are on the simpler end and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Harwich, the choice will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Harwich

EcoWatch differs from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Harwich and ranked them using the following methodology:

Service Area

Since this is a guide for Harwich, we only included companies that serve the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Harwich.

Work Quality

When picking new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have nice things to say about their experience with a certain installer, it won’t be featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Harwich’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Harwich window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
