How Installing Energy-Efficient Windows in Tewksbury Saves You Money
There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Better temperature control in your home: Residing in a hot place like Tewksbury can often mean needing your AC to keep your home cool. Energy-efficient windows can lower the amount of cool air lost through your windows when cooling your home.
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease that number, therefore saving you about 12% more on your bills.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Tewksbury
When considering window installation, each company offers different services and prices. Let's go over some average costs and services.
How Much Do New Windows Cost?
The national average cost to replace a single window is about $600 but can range from $200 to $1,200. But costs will vary significantly depending on the number of windows you need, the quality of your products, the current condition of your home and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts 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. These savings vary depending on your local climate, energy rates and individual home characteristics.
How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are generally the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
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 also involves other materials, such as insulation and drip edges, which raise the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won't carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
Your window installation company should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Tewksbury
The EcoWatch Reviews team is different from most reviewers since we're examining these companies through a sustainability lens. We have evaluated the top window replacement companies in Tewksbury mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Tewksbury area so you can find a quality window installation company near you.
Work Quality
When choosing 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 rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have good feedback about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers may not provide the highest quality service. On the other hand, we want to ensure 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 to many homeowners. That's why window installation companies with 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 are going to earn higher rankings by our standards. We like to see at least ten years of experience.
