• Save money on energy bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you'll need less energy to heat or cool your house.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Stratham, that's about 152 pounds per year on average.

Estimated Cost of Window Replacement in Stratham

Let's take a look at the cost of window replacement and the kinds of services offered by installers.

How Much Do New Windows Cost?

Typically, Stratham homeowners can expect their window installations to range from $250 to $1,200. The average cost is at around $600. But costs will differ significantly depending on the number of windows you need, the quality of your products, the current condition of your home and your location. Many window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.

It's important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Stratham homeowners $435+ a year when replacing single-pane windows.

We advise requesting free quotes from several window installation companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first question to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?

A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.

Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Stratham

In our hunt to find the most reliable, eco-friendly window installers in Stratham, the EcoWatch Reviews team assessed many companies before deciding on these. Along with energy efficiency, we evaluated several window installers in Stratham and assigned rankings using the following methodology:

Service Area

Since this is a guide for Stratham, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Stratham.

Work Quality

When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in 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

Cheaper windows certainly don't mean better windows, but we know many of our readers want 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

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Stratham's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Stratham window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
