How Installing Energy-Efficient Windows in Harlem Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could help you:

• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on electricity bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your home.
• Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 449 pounds.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.

Getting free quotes from several installers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

In general, there are two kinds of window installation services companies offer: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, like 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. A pocket installation involves replacing a window without replacing the frame. This means instead of removing the whole unit and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Harlem, the decision 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 Harlem

EcoWatch reviews differ from other reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Harlem so you can find the best window installation company near you.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you choose. 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 very important review factor is customer feedback. If most customers don’t have nice feedback about their service from a certain installer, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, 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 to many homeowners. That’s why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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