How Installing Energy-Efficient Windows in Westford Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to consider making the switch:

  • Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 139 pounds per year on average.
  • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Upgrading to energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Westford

Let’s go over the cost of window replacement and the types of services offered by installers.

How Much Do New Windows Cost?

The average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. This is due to the fact that window installations depend on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

It’s also worth noting that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your Westford home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

In general, there are two types of window replacement services you can get: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, including insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves replacing a window without taking out the complete frame, which tends to be less expensive than a full-frame installation.

Your window installation company should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Westford

In our search to make your home improvements easier and more eco-friendly in Westford, EcoWatch examined dozens of companies before deciding on these. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company included in our guide 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

We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, quality of parts, cost, warranty, quality of installation and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the highest quality service. Still, 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 offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of 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 these issues. If a company has less than 10 years of experience, it loses points in this category.
