How Installing Energy-Efficient Windows in Cambridge Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, such as:
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient windows can help lower that number, which helps you save $469 a year on your bills.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Cambridge, that's about 139 pounds per year on average.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Cambridge
Each window replacement company offers various services and has different price points based on a few factors.
How Much Do New Windows Cost?
Generally, homeowners in Cambridge can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. But prices vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which will add extra costs to your project.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Cambridge homeowners $469+ per 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, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
In regard to window installations, in general there are two kinds that your provider will have: full-frame and pocket installations.
A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
If you're unsure which window installation service you need, your installer can advise you. Typically, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Cambridge
The EcoWatch Reviews team is different from most reviewers since we examine these companies through a sustainability lens. We've reviewed the best window installers in Cambridge mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Cambridge, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Cambridge.
Work Quality
When selecting new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you choose. 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
We analyzed trends in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including warranty, quality of installation, cost, quality of parts, professionalism 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. Still, 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
As discussed, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Cambridge's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Cambridge window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Cambridge, MA Window Replacement FAQs
What is the typical cost to install new windows?
The average cost of installing a single window ranges from $450 to $650. There are a variety of factors that affect the cost, including styles and sizes of windows, your property's location, how energy-efficient the windows are, the materials used in designing the windows, local labor costs and the number of windows.
What type of window is the best for energy efficiency?
A window's energy efficiency depends on several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Do I really need to use a window installation company?
You should use a window installation professional whenever you want to replace your windows. Installing windows is a complex process that can take a lot of time, so it's best left to the professionals.
Should I replace my windows all at once?
If your windows are more than 20 years old, it's most likely time to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
