How Installing Energy-Efficient Windows in Brewster Saves You Money

When you upgrade to energy-efficient windows, you may see some perks, including:

• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Brewster, that’s about 139 pounds per year on average.
• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Switching to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Brewster

Let’s take a look at the cost of updating your windows and the types of services offered by installers.

How Much Do New Windows Cost?

Generally, Brewster homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at around $600. These estimates vary based on specific characteristics of your installation, such as type, number of windows, material, size, the location of your home and more.

Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in Brewster

EcoWatch reviews differ from other reviews because we’re examining these companies through a sustainability lens. We’ve reviewed the top window installers in Brewster mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Brewster, we paid more attention to 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 Brewster.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, quality of installation, professionalism, cost, quality of parts and more.

Cost

This one is a give-and-take: similar to other services, cheap window installers are not going to provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. 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 Brewster’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Brewster window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
