How Installing Energy-Efficient Windows in Watertown Town Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:
- Save money on electricity bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll need less energy to heat or cool your home.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
- Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 139 pounds per year on average.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Watertown Town
Let’s go over the cost of window installation and the types of services you may need for your home.
How Much Do New Windows Cost?
On average, homeowners in Watertown Town can expect that most replacement window installations will cost between $250 and $1,200, with the average cost at around $600. These estimates are based on specific characteristics of your installation, like material, size, type, number of windows, the location of your home and more.
Keep in mind that energy-efficient windows may cost more, but Energy Star estimates 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 replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide 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 considering a replacement is to figure out whether you should get a full-frame or pocket installation.
Full-frame installations involve replacing the full window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable deterioration. These installations are more involved and will increase the overall cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company can help you choose which type of installation you need.

How We Choose the Best Window Installers in Watertown Town
The EcoWatch Reviews team differs from most reviewers, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Watertown Town and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, cost, professionalism, quality of installation, warranty and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. Still, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a sizable investment, so you’ll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) 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 installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Watertown Town, MA Window Replacement FAQs
How much should a window install cost?
The national average cost of installing a window is around $600 but can range from $200 to $1,200, based on a variety of factors. The price is often influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What type of window is the most energy-efficient?
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 get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.
What do window installers do?
Window installers travel to your house to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is done.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, it shouldn’t be raining, since rain can make the installation more difficult.
How long does it take to install windows?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
