How Installing Energy-Efficient Windows in Brookline 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 switch include the following:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on electricity bills: Because energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save about $454 annually on your energy bills in Brookline.
• Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
• Reduce your carbon footprint: By using less energy after you switch to Energy Star certified windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Brookline

Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the average costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

Typically, homeowners in Brookline can expect that most replacement window installations will range from $250 to $1,200, with the average cost sitting at around $600. But costs differ remarkably 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 provide door installations, which will add extra costs to your project.

Whether or not you opt for energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $454 a year on your energy bills in Brookline.

Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using 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 provide decent insulation for your home.

What Services do Window Installers Offer?

Generally, there are two kinds of window installation services companies provide: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant damage or rot. These installations are more involved and will increase the total cost. A pocket installation involves replacing a window without replacing the frame. So, instead of removing the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company will be able to help you choose what’s best for your needs. In Brookline, the decision will mostly be based on the age of your windows and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Brookline

EcoWatch reviews are different from other reviews, as we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:

Service Area

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

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer featured in our guide to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive things to say about their service from a certain company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers are not going to provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Brookline’s climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Brookline window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
