How Installing Energy-Efficient Windows in Hampton Saves You Money
There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful 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- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 152 pounds per year on average.
Estimated Cost of Window Replacement in Hampton
Each window installation company offers varying services and has different prices based on a few factors.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. Costs will differ significantly based on the quality of your products, the current condition of your home, the number of windows you need and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.
With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly during the winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Hampton homeowners $435+ each year after replacing single-pane windows.
We advise requesting free quotes from several window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
In general, there are two types of window replacement services you can get: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your installers will replace the whole window, including the frame, trim and sill. A pocket installation entails replacing a window within the existing frame. So, instead of removing the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to help you decide what’s best for your needs. In Hampton, the decision will mostly be based on how old your windows are and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Hampton
The EcoWatch Reviews team is different from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:
Service Area
Because this is a guide for Hampton, we gave more points to companies that serve 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 Hampton.
Work Quality
When it comes to new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window 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 very important review factor is customer feedback. If the majority of customers don’t have nice feedback about their experience with a certain company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installation companies won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a sizable investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Hampton’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Hampton window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Hampton, NH Window Replacement FAQs
What is the average cost to install windows?
The average cost of replacing one window ranges between $450 and $650. There are a variety of factors that influence how much it costs, such as the number of windows, how energy-efficient the windows are, your property’s location, styles and sizes of windows, local labor costs and the materials used in designing the windows.
What are the most common types of replacement windows?
The most common types of windows for homes include: bay windows, slider windows, casement windows, transom windows, double-hung and single-hung windows, awning windows and picture windows.
What services do window replacement companies offer?
Window installers go to your home to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation is done.
Should I replace all my windows at once?
If you’re upgrading your windows to save on your energy bills, replacing all the windows at the same time is the only way to gain that benefit. However, if you have only one or two windows that are broken or leaky, you can replace just those.
How long does window installation usually take?
Because a window takes about 30 minutes to install, around 16 windows can be installed in a typical 8-hour work day.
