How Installing Energy-Efficient Windows in Cambridge Saves You Money

When you switch to energy-efficient windows, you may see some perks, including:

• Save on electricity bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save about $217 annually on your energy bills in Cambridge.
• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
• Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 249 pounds per year on average.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.

Estimated Cost of Window Replacement in Cambridge

Each window installer offers various services and has different price points depending on several factors.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. These estimates are based on specific characteristics of your installation, such as size, the location of your home, number of windows, material, type and more.

It’s important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Cambridge homeowners $217+ a year when replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

When considering window installations, in general there are two kinds that your installer will offer: full-frame and pocket installations.

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

If you’re still trying to decide which kind of installation to get, you can consult with your provider and get their advice. The decision mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Cambridge

In our search to find the most reliable, eco-friendly window installers in Cambridge, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings based on the following methodology:

Service Area

Since this is a guide for Cambridge, we gave more points to companies that cover the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Cambridge.

Work Quality

When selecting new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, quality of parts, quality of installation, cost, warranty and more.

Cost

This one is a give-and-take: as with other services, cheap window installers are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why 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, water damage and rot. We factored in local experience to reflect the ability of Cambridge window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
