How Installing Energy-Efficient Windows in Portsmouth Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, including:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if your home is on the older side.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Portsmouth, that’s about 131 pounds per year on average.
- Save on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that amount, which helps you save more on your bills.
Estimated Cost of Window Replacement in Portsmouth
Let’s go over the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Typically, Portsmouth homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. These figures vary based on the specifics of your installation, like number of windows, material, the location of your home, type, size and more.
It’s important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Portsmouth homeowners $378+ a year when replacing single-pane windows.
We recommend requesting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. As this kind of installation is more involved, it will be more expensive than a pocket installation. A pocket installation means replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
If you’re not sure which window installation service you should get, your installer should be able to advise you. Typically, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Portsmouth
EcoWatch reviews are different from other reviews because we’re examining these companies through a sustainability lens. We have evaluated the top window replacement companies in Portsmouth mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Portsmouth, we gave more points to companies that cover the city. There are certainly reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Portsmouth.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, professionalism, cost, warranty, quality of parts and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Portsmouth’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Portsmouth window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Portsmouth, RI Window Replacement FAQs
What is the typical cost to install windows in a home?
The national average cost of replacing a single window is around $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 location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What kind of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.
When do I have to use a window installation company?
You should use a window installation professional whenever you want to replace your windows. Installing windows is a complex process that can take a lot of time, so it’s best handled by the professionals.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you most likely need to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
