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.

Although green energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your home’s efficiency can also have a considerable impact on home energy conservation. When it’s the middle of summer, your old and drafty windows could be making your home more difficult to cool and more uncomfortable for you.

That’s also bad news for the environment, as the additional energy used by leaky windows increases your carbon footprint.

Efficient windows are of particular importance in Williamstown, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $309 per year.

How Installing Energy-Efficient Windows in Williamstown Saves You Money

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

  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
  • Save on electricity bills: Because energy-efficient windows decrease the amount of energy needed to heat or cool your home, they can help you save around $309 annually on your energy bills in Williamstown.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Williamstown, that’s about 206 pounds per year on average.

Estimated Cost of Window Replacement in Williamstown

Windows come in different shapes and sizes, so costs and services will vary considerably. Here are the average costs and services that you’ll find from the average window installation company.

How Much Do New Windows Cost?

Typically, homeowners in Williamstown can expect that most window installations will cost between $250 and $1,200, with the average cost sitting at about $600. But costs will vary considerably based on your location, the number of windows you need, the current condition of your home and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $309 a year on your energy bills in Williamstown.

Requesting free quotes from several providers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first step when considering a replacement is to figure out whether you need a full-frame or pocket installation.

Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot. With this service, your professionals will replace the full window, including the trim, frame and sill. 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 carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

If you’re still trying to decide which kind of installation you should get, you can ask your installer and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Williamstown

In our search to find the most reliable, eco-friendly window installers in Williamstown, EcoWatch examined many companies before landing on these. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:

Service Area

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

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer in our guide to make sure its technicians 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 online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, quality of parts, warranty, cost, professionalism and more.

Cost

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

Warranty

As discussed, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
