How Installing Energy-Efficient Windows in Cambridge Saves You Money
By switching to energy-efficient windows, you can take advantage of several benefits, such as:
- Protect your valuables: Many energy-efficient 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.
- Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
- Save on power bills: Because energy-efficient windows lower 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 Cambridge.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty.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.
Estimated Cost of Window Replacement in Cambridge
When looking into window installation, each company provides varying services and prices. Let’s take a look at some average costs and services.
How Much Do New Windows Cost?
On average, Cambridge homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. These numbers are based on the specifics of your installation, including number of windows, material, size, the location of your home, type and more.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Something else that affects the total cost is the material you choose for your frame. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they provide 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?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the complete window, including the sill, trim and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot. These installations are more involved and will raise overall costs. Pocket installations are on the simpler end and won’t cost as much because they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
Your window installation company can recommend the best type for your project. In Cambridge, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Cambridge
EcoWatch reviews are different from other reviews, as we’re examining these companies through a sustainability lens. We’ve decided to review the best window installation companies in Cambridge mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your electricity 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 Cambridge so you can find a quality window installation company near you.
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 company on this list to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, professionalism, warranty, cost, quality of installation and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that provide lengthy warranties for products, parts and labor 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 years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Cambridge, MA Window Replacement FAQs
What is the average cost to replace windows?
The national average cost to replace one window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often dependent on the location of your property, the type and material of the window and the size of the window.

What are the kinds of windows?

Can I install my own windows?
If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. But if you don’t have the time or know-how, we recommend getting a professional to do it for you.
What time of year is a good time to replace my windows?
Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.
