20 Best Window Companies in Wellesley, MA (2025 Reviews)

How Installing Energy-Efficient Windows in Wellesley Saves You Money

By upgrading to energy-efficient windows, you can benefit in several ways, such as:

• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
• Save money on power bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of household energy use. Switching to energy-efficient windows can help reduce that amount, which helps you save $454 a year on your bills.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
• Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 139 pounds.

Estimated Cost of Window Replacement in Wellesley

Let’s go over the cost of installing new windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

Typically, homeowners in Wellesley can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. This is because window installations are based on several factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.

It’s important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Wellesley homeowners $454+ a year when replacing single-pane windows.

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 total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves other materials, such as 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 entails replacing a window within the existing frame. This means instead of taking out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to help you decide what’s best for your needs. In Wellesley, the decision will mostly depend on the age of your windows and if there’s any moisture damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Wellesley

The EcoWatch Reviews team differs from other reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Wellesley and ranked them using the following methodology:

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured on this list to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.

This one is a give-and-take: similar to most services, cheap window installation companies may not 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 well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
