Why you can trust EcoWatch
A review of the best window installation companies in Mendon may not seem like the most compelling article on EcoWatch, but trust us, windows have more of an impact on your life than you might realize. Drafty windows can cost you in electric bills. In fact, the Department of Energy estimates that about 30% of your home's heat or cool air could be lost through your windows.
That's also bad news for the environment because the additional energy used by damaged windows increases your carbon footprint.
Unlike other review sites, EcoWatch ranks window installation companies based on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Mendon Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Reduce your carbon footprint: In Mendon, you can lower your indirect greenhouse gas emissions by about 139 pounds per year after you upgrade to energy-efficient windows.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Mendon
When considering window installation, each company offers different services and prices. Let's go over some typical costs and services.
How Much Do New Windows Cost?
Although the typical to replace one window is about $600, it can range from $200 to $1,200. This is because the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially during the winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Mendon homeowners $440+ each year after replacing single-pane windows.
How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are usually the most expensive, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat 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 on installing new windows is: Do you want a full-frame installation or a pocket installation?
Full-frame installations entail replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable rot. Because full-frame installations are more involved, they will raise the overall cost. 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 will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Mendon
EcoWatch reviews are different from most reviews, as we examine these companies through a sustainability lens. We have assessed the best window replacement companies in Mendon mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Mendon so you can find the right window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured on this list to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good feedback about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a proven track record in the industry. 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.
Mendon, MA Window Replacement FAQs
How much does window installation cost?
The average cost of replacing a window ranges from $450 to $650. There are many factors that affect the cost, such as styles and sizes of windows, your property's location, the materials used in designing the windows, the number of windows, how energy-efficient the windows are and local labor costs.
What kind of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
When should I use a window installation company?
Unless you're handy and have all the tools you need to replace your own windows, we recommend hiring the pros. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.
What time of year is a good time to replace my windows?
While you can install windows any time of year, warmer weather is generally better for replacing windows. Additionally, the weather should be dry, since rain can make the installation more difficult.
Should I replace my windows all at once?
If you're upgrading your windows to get more efficient windows, replacing all your windows at once is the only way to gain that benefit. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
