Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Whether you're doing renovations or have damaged windows, windows play a key role in conserving your home's energy. According to the Department of Energy, heat gained or lost through old or damaged windows could account for 25-30% of residential energy climate control usage.

Installing upgraded, efficient windows on your house can help you save money each month on your electric bills — and you can help the environment as well.

Efficient windows are of particular importance in Westford, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $464 each year.

How Installing Energy-Efficient Windows in Westford Saves You Money

By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:

  • Save on power bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll use less energy to heat or cool your home.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
  • Reduce your carbon footprint: In Westford, you can lower your indirect greenhouse gas emissions by about 139 pounds per year once you switch to energy-efficient windows.

Estimated Cost of Window Replacement in Westford

Let's take a look at the cost of installing new windows and the types of services you may need for your home.

How Much Do New Windows Cost?

Generally, homeowners in Westford can anticipate that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which will make your project cost more.

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

Requesting free quotes from multiple companies is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

Generally, there are two types of window replacement services companies offer: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has significant rot. With this service, your installers will replace the total window, including the trim, frame and sill. A pocket installation means replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

If you're still trying to decide which type of installation you should get, you can ask your provider and get their advice. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Westford

EcoWatch reviews differ from most reviews because we look at these companies through a sustainability lens. We have decided to assess the top window replacement companies in Westford primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can reduce your 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 Westford, we only included companies that serve the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Westford.

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company included in our guide to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

This one is a give-and-take: similar to most services, cheap window installers won't always provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that offer a range 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 provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Westford, MA Window Replacement FAQs

How much should window installation cost?

The national average cost of replacing a window is about $600 but can range between $200 and $1,200, based on several factors. The price is often influenced by the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

Which type of window is the best?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.

What services do window replacement companies offer?

Window installation professionals cover the entire process — from replacing your old windows with brand new ones to cleaning up after the windows have been put in place. In addition, a lot of companies offer window manufacturing, customization and repairs.

How do you know it's time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.

Should I replace all my windows at once?

If you want to get more efficient windows and save money on energy costs, replacing all of your windows at the same time is the only way to gain that benefit. On the other hand, if you have just one or two windows that are broken or leaky, you can replace just those.
