How Installing Energy-Efficient Windows in Boston Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could help you:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
• Save on power bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that amount, which helps you save $451 a year on your bills.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Boston, that’s about 139 pounds per year on average.

Estimated Cost of Window Replacement in Boston

Each window installer offers varying services and has different prices based on several factors.

How Much Do New Windows Cost?

Typically, Boston homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. These estimates vary based on the specifics of your installation, including type, number of windows, size, material, the location of your home and more.

It’s important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Boston homeowners $451+ a year when replacing single-pane windows.

Asking for free quotes from multiple companies is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

There are generally two types of window installation services: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve other materials, such as insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

Your window replacement company will be able to help you choose what’s best for your needs. In Boston, the decision will mostly be based on how old your home is and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Boston

EcoWatch is different from other reviewers, as we assess these companies through a sustainability lens. We have evaluated the best window replacement companies in Boston primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Boston so you can find a quality window installation company near you.

Work Quality

When selecting new windows, the quality and variety 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 consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If most customers don’t have nice feedback about their experience with a certain company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer 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 be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
