Why you can trust EcoWatch
A review of the best window installation companies in Exeter may not seem like the most captivating article on EcoWatch, but trust us, windows have a more direct impact on your life than you might realize. Outdated windows can cost you in energy bills. As a matter of fact, the Department of Energy estimates that 25-30% of your home's heat or cool air could be lost through your windows.
That's also bad news for the environment, as the extra energy required by drafty windows increases your carbon footprint.
Efficient windows are especially important in Exeter, where winters are long and cold. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $435 a year.

How Installing Energy-Efficient Windows in Exeter Saves You Money
There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Better temperature control in your home: Living in a cold city like Exeter can often mean depending on your heater to keep your home cool. Energy-efficient windows can cut back on the amount of heat lost through your windows when heating your home.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
- Save money on energy bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $435 annually on your energy bills in Exeter.
Estimated Cost of Window Replacement in Exeter
Let's take a look at the cost of window replacement and the kinds of services you may need for your home.
How Much Do New Windows Cost?
On average, Exeter homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost you is based on several factors, including material, the location of your home, size, type, number of windows and more.
It's also worth bearing in mind that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that upgrading the windows on your Exeter home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Asking for free quotes from several installers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
In general, there are two types of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations are usually recommended when you want a new style or your window has a lot of rot. With this service, your installers will replace the complete window, including the sill, trim and frame. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company will be able to help you choose what's best for your needs. In Exeter, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Exeter
EcoWatch reviews differ from other reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for Exeter, we gave more points to companies that cover the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Exeter.
Work Quality
When installing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have good things to say about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a hefty investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Exeter's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Exeter window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Exeter, NH Window Replacement FAQs
What is the average cost to replace windows?
The typical cost of installing one window ranges from $450 to $650. There are a variety of factors that influence how much it costs, such as local labor costs, the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are, the number of windows and your property's location.
What are the different kinds of windows?
There are several different types of windows you can get for your home, including casement windows, transom windows, bay windows, slider windows, awning windows, double-hung and single-hung windows and picture windows.
What do window installers do?
