20 Best Window Companies in Claremont, NH (2025 Reviews)

How Installing Energy-Efficient Windows in Claremont Saves You Money

By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:

• Reduce your carbon footprint: In Claremont, you can reduce your indirect greenhouse gas emissions by about 152 pounds per year when you switch to energy-efficient windows.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Replacing your windows with energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Claremont

Each window installation company offers various services and has different prices depending on a few factors.

How Much Do New Windows Cost?

Even though the national average cost to replace one window is about $600, it can range from $200 to $1,200. These numbers are based on specific characteristics of your installation, such as material, size, number of windows, the location of your home, type 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 you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

Requesting free quotes from several providers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can help you choose which type of installation you should get.

The EcoWatch Reviews team differs from other reviewers, as we’re examining these companies through a sustainability lens. We’ve reviewed the top window installation companies in Claremont primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

When installing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you get. 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 find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of installation, cost, quality of parts, warranty, professionalism and more.

Cost

This one is a give-and-take: as with other services, cheap window installation companies won’t always provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
