How Installing Energy-Efficient Windows in Keene Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could benefit you:
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on power bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $489 annually on your energy bills in Keene.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Keene
Each window installer offers various services and has varying costs based on several factors.
How Much Do New Windows Cost?
On average, homeowners in Keene can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. But prices 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 companies also provide door installations, which have a higher price tag.
It's important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Keene homeowners $489+ a year when replacing single-pane windows.
Requesting free quotes from several providers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
Generally, there are two kinds of window replacement services companies offer: 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. Because full-frame installations are more involved, they will increase the overall cost. A pocket installation involves replacing a window without replacing the frame. This means instead of removing the whole window and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still trying to decide which kind of installation to get, you can consult with your provider and get their recommendation. The decision mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Keene
EcoWatch reviews are different from other reviews, as we look at these companies through a sustainability lens. We've decided to assess the top window installation companies in Keene mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Keene, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Keene.
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 in our guide to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have nice things to say about their service from a certain company, it won't be featured on EcoWatch.
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 providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Keene, NH Window Replacement FAQs
What is the average cost to install new windows?
The national average cost of installing a window is about $600 but can range from $200 to $1,200, depending on several factors. The price is typically influenced by the type and material of the window, the location of your property and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the different kinds of windows?
The most common types of windows for homes are transom windows, bay windows, casement windows, double-hung and single-hung windows, picture windows, awning windows and slider windows.
What do window installers do?
Window installers visit your property to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.
What time of year is a good time to replace my windows?
Even though you can install windows any time of year, warmer weather is typically better for installing replacement windows. Additionally, it shouldn't be raining, since rain can make the installation harder.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all of the windows together is the only way to see a noticeable difference. However, if you have just a few windows that are broken or leaky, you can replace just those.
