Why you can trust EcoWatch
Whether you're updating for aesthetics or have old windows, windows play a crucial role in conserving electricity in your home. Drafty windows can cost you in electric bills. In fact, the Department of Energy estimates that 25-30% of your house's heat or cool air could be lost through your windows.
That's also bad for the environment because the extra energy required by damaged windows increases your carbon footprint.
We've put together this guide on the top installation companies to help you in your research, so you can not only benefit from brand new windows, but also save money on your electricity bills.

How Installing Energy-Efficient Windows in Hampton Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, such as:
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- More efficient energy use in your home: In Hampton where the winters can be cold, energy-efficient windows lower the amount of heat that is lost through your windows, which makes it easier to keep your house warm.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Hampton
Each window installer offers various services and has different costs based on several factors.
How Much Do New Windows Cost?
Typically, Hampton homeowners can expect their window installations to range from $250 to $1,200. The average cost is at about $600. These numbers vary depending on the specifics of your installation, including the location of your home, size, number of windows, material, type and more.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $435 a year on your energy bills in Hampton.
The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are generally the most expensive, but it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation means replacing a window within the existing frame, which is usually less expensive than a full-frame installation.
If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Hampton, the choice will mostly depend on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Hampton
EcoWatch reviews differ from most reviews because we evaluate these companies through a sustainability lens. We have reviewed the top window installation companies in Hampton primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to lower power 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 Hampton so you can find the right window installation company near you.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer in our guide to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, warranty, quality of parts, quality of installation, cost and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a serious investment, so you'll want to make sure that investment is protected. 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Hampton, NH Window Replacement FAQs
How much should window installation cost?
The national average cost to install a window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is typically dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the most common types of replacement windows?
There are various kinds of windows you can get for your home, such as transom windows, double-hung and single-hung windows, awning windows, slider windows, casement windows, picture windows and bay windows.
What do window installers do?
Window installation companies cover the entire process — from replacing your old windows with brand new ones to cleaning up afterward. In addition, some companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the house, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
