How Installing Energy-Efficient Windows in Somerville Saves You Money

There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Somerville, that’s about 139 pounds per year on average.
• Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that number, which helps you save more on your bills.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Somerville

Each window installer offers varying services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

On average, Somerville homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. But costs will differ significantly based on the quality of your products, your location, the current condition of your home and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.

It’s also worth bearing in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Somerville home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

We recommend getting free quotes from several window installation companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first question to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?

Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the complete window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

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

How We Choose the Best Window Installers in Somerville

In our hunt to find the most reliable, eco-friendly window installers in Somerville, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated several window installers in Somerville and ranked them based on the following methodology:

Service Area

Because this is a guide for Somerville, we only included companies that cover the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Somerville.

Work Quality

When selecting new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good things to say about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a sizable investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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