How Installing Energy-Efficient Windows in Belmont Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
- Reduce your carbon footprint: In Belmont, you can reduce your indirect greenhouse gas emissions by about 152 pounds per year when you install energy-efficient windows.
- Save on energy bills: Installing energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Belmont
When researching window installation, each company offers different services and prices. Let's look at some average costs and services.
How Much Do New Windows Cost?
According to our market research, the typical cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. But costs will differ considerably depending on your location, the number of windows you need, the quality of your products and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.
It's also worth keeping in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Belmont home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
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 a bit more 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 provide decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot. With this service, your professionals will replace the total window, including the frame, sill and trim. A pocket installation involves replacing a window without replacing the frame. So, instead of tearing out the whole window and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Belmont, the choice will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Belmont
In our hunt to find the most reliable, eco-friendly window installers in Belmont, EcoWatch evaluated dozens of companies before deciding on these. We've decided to assess the top window installation companies in Belmont mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, quality of parts, quality of installation, professionalism, cost and more.
Cost
This one is a give-and-take: as with other services, cheap window companies won't always provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, 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 are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Belmont, NH 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 few different 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, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
The most common kinds of windows for homes include: slider windows, awning windows, transom windows, bay windows, double-hung and single-hung windows, casement windows and picture windows.
When should I use a window installation company?
Unless you're handy and have the tools needed to replace your own windows, we recommend hiring a professional. The window installation process is complicated and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.
How do you know it's time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, it's most likely time to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
