How Installing Energy-Efficient Windows in Belmont Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Save on electricity bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $464 annually on your energy bills in Belmont.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 139 pounds per year on average.
Estimated Cost of Window Replacement in Belmont
When considering window installation, each company provides different services and costs. Let’s look at some typical costs and services.
How Much Do New Windows Cost?
The average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. How much it will cost varies based on several factors, including the location of your home, type, number of windows, material, size and more.
Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $464 a year on your energy bills in Belmont.
Another factor that influences the total cost is the material you select for your frame. Aluminum frames are generally the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In regard to window installations, in general there are two types that your provider will offer: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation entails installing a new window within the existing frame. So, instead of taking out the whole window and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you’re not sure which type of window installation service you should get, your installer should be able to assist you. Typically, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Belmont
EcoWatch reviews differ from most reviews, as we assess these companies through a sustainability lens. We’ve reviewed the top window replacement companies in Belmont 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 cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Belmont, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Belmont.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, warranty, quality of parts, professionalism, cost and more.
Cost
This one is a give-and-take: similar to other services, cheap window installers are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That’s why 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 been in the industry for quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Belmont, MA Window Replacement FAQs
How much does window installation cost?
The national average cost to replace a window is around $600 but can range from $200 to $1,200, based on several factors. The price is often dependent on the type and material of the window, the location of your property and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which type of window is the best?
A window’s energy efficiency is influenced by several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window installation companies offer?
Window installers visit your home to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is finished.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is often better for replacing windows. In addition, the weather should be dry, as rain can make the installation harder.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
