How Installing Energy-Efficient Windows in Exeter Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to think about making the switch:
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
- Save money on energy bills: Since energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save around $435 annually on your energy bills in Exeter.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Exeter, that's about 152 pounds per year on average.
Estimated Cost of Window Replacement in Exeter
Each window replacement company offers varying services and has different price points based on a few factors.
How Much Do New Windows Cost?
According to our market research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. But costs will vary significantly based on the quality of your products, the current condition of your home, your location and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. These extra services will increase your overall project costs.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
Getting free quotes from several installers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
When it comes to window replacements, there are typically two types that your installer will have: full-frame and pocket installations.
A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations are on the simpler end and won't carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
Your window installation company will be able to recommend the best type for your project. In Exeter, the decision will mostly be based on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Exeter
In our search to find the most reliable, eco-friendly window installers in Exeter, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We have decided to evaluate the best window installation companies in Exeter mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Exeter so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good things to say about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a wide range 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 that offer 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 experience earn higher rankings by our standards. We like to see at least ten years of experience.
Exeter, NH Window Replacement FAQs
What is the average cost to install new windows in a home?
The average cost of installing a window ranges between $450 and $650. There are many factors that influence how much it costs, such as styles and sizes of windows, the materials used in designing the windows, the number of windows, local labor costs, your property's location and how energy-efficient the windows are.
What type of window is the most energy-efficient?
Generally, double-pane windows are 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 attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies do?
Window installation professionals cover the entire process — from replacing your old windows with new ones to cleaning up afterward. Additionally, a lot of companies offer window manufacturing, customization and repairs.
When is the best time of year to replace 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 ensure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably 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.
