How Installing Energy-Efficient Windows in Glens Falls Saves You Money

When you switch to energy-efficient windows, you may see several perks, including:

• Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 65 pounds per year on average.
• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
• Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?

A full-frame installation replaces the full window, such as the sill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations are on the simpler end and won’t carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you’re still debating which kind of installation you should get, you can consult with your installer 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 Glens Falls

The EcoWatch Reviews team differs from most reviewers since we look at these companies through a sustainability lens. We’ve reviewed the top window replacement companies in Glens Falls mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Glens Falls, we gave more points to companies that cover the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Glens Falls.

Work Quality

When selecting new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive feedback about their experience with a certain window installation company, it won’t be featured on EcoWatch.

Cost

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

Warranty

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

Years of Experience

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