Why you can trust EcoWatch
A review of the top window installation companies in Westborough may not seem like the most interesting article on the EcoWatch site, but trust us, windows have a more direct impact on your life than you might realize. Drafty windows could lead to having higher electricity bills during the winter or summer months.
That's also bad for the environment because the additional energy used by leaky windows increases your carbon footprint.

How Installing Energy-Efficient Windows in Westborough Saves You Money
When you upgrade to energy-efficient windows, you may see a few perks, such as:
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 139 pounds.
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save some money on your bills.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Westborough
Let's go over the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Although the average to install a single window is about $600, it can range anywhere from $200 to $1,200. But costs will differ significantly depending on the number of windows you need, your location, the quality of your products and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.
It's also worth bearing in mind that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your Westborough home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We advise requesting free quotes from multiple window companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which increase the total cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing out the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Westborough, the decision will mostly be based on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Westborough
EcoWatch reviews differ from other reviews because we assess these companies through a sustainability lens. We have assessed the best window replacement companies in Westborough mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve Westborough so you can find the right 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 on this list to make sure its contractors 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 the majority of customers don't have nice things to say about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Westborough, MA Window Replacement FAQs
How much does window installation cost?
The national average cost to replace a window is about $600 but can range between $200 and $1,200, depending on several factors. The price is generally influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the different types of windows?
The most common kinds of windows for homes include: double-hung and single-hung windows, picture windows, casement windows, bay windows, transom windows, awning windows and slider windows.
When should I use a window installation company?
Unless you have experience with home improvement projects and have the time needed to replace your own windows, we recommend hiring a professional installer. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and much safer alternative.
What time of year is a good time to replace my windows?
Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
Should I replace my windows all at once?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
