Why you can trust EcoWatch
The EcoWatch Reviews team is all about finding solutions for eco-conscious homeowners in Hampstead. Damaged or outdated windows can cost you in energy bills. As a matter of fact, the Department of Energy estimates that 25-30% of your house's heat or cool air could be lost through your windows.

How Installing Energy-Efficient Windows in Hampstead Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could benefit you:
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Hampstead, that's about 152 pounds per year on average.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
- Save on electricity bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $435 annually on your energy bills in Hampstead.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Hampstead
Windows come in different shapes, styles and purposes, so costs and services will differ greatly depending on your project. Below, we go over the typical cost and services that you'll find from window installers.
How Much Do New Windows Cost?
The average cost to replace a single window is about $600 but can range from $200 to $1,200. How much it will cost you is based on several factors, like material, type, number of windows, size, the location of your home and more.
With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly during the winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Hampstead homeowners $435+ each year after replacing single-pane windows.
Another factor that affects the total cost is the material of the frame you select. Aluminum frames are usually the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In regard to window replacements, in general there are two kinds that your provider will have: full-frame and pocket installations.
A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. A pocket installation means replacing a window without taking out the complete frame, which tends to be less expensive than a full-frame installation.
Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Hampstead
The EcoWatch Reviews team differs from other reviewers since we assess these companies through a sustainability lens. We have reviewed the best window installers in Hampstead mostly 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 reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Hampstead area so you can find the right window installation company near you.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer featured on this list to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including cost, quality of parts, warranty, professionalism, quality of installation and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try 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
As discussed previously, windows are a sizable investment, so you'll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Hampstead's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Hampstead window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Hampstead, NH Window Replacement FAQs
What is the typical cost to install new windows?
The national average cost of replacing one window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is often dependent on the location of your property, the size of the window and the type and material of the window. Also, keep 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 types of windows?
The most common kinds of windows for homes include: awning windows, casement windows, bay windows, transom windows, picture windows, double-hung and single-hung windows and slider windows.
When do I need to use a window installation company?
You should use a window installation professional whenever you want to upgrade your windows. Installing windows is a involved process that can be difficult and time-consuming, so it's best handled by the professionals.
How long does it usually take to install windows?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.
What time of year is the best time to replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of 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 doesn't necessarily matter that much. What's most important is that the weather should be dry.
