How Installing Energy-Efficient Windows in Boston Saves You Money
There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Save money on energy bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $368 annually on your energy bills in Boston.
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Boston
Each window installer offers various services and has different price points based 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. 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 replacements, which will add extra costs to your project.
Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when planning a replacement is to clarify whether you need a full-frame or pocket installation.
Full-frame installations involve replacing the entire 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 rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation entails installing a new window within the frame that's already there. So, instead of tearing out the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're unsure which window installation service you need, your installer can advise you. Generally, the decision depends 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 Boston
The EcoWatch Reviews team is different from most reviewers because we evaluate these companies through a sustainability lens. We've evaluated the top window installation companies in Boston mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Boston, 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 Boston.
Work Quality
When picking new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, cost, quality of installation, quality of parts, warranty and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Boston's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Boston window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Boston, NY Window Replacement FAQs
How much does window installation cost?
The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
When do I need to use a window installation company?
You should hire a window installation company whenever you want to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best handled by the professionals.
How long does it take to install windows?
Because a window takes about 30 minutes to install, about 16 windows can be installed during an 8-hour work day.
What time of year is a good time to replace my windows?
Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.
