20 Best Window Companies in Cambridge, MA (2025 Reviews)

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• Protect your investment: When you have an older home, your windows could also be outdated or drafty.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.
