How Installing Energy-Efficient Windows in Windham Saves You Money
When you switch to energy-efficient windows, you may see several benefits, such as:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
- 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.
- 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. Upgrading to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Windham
Windows come in various shapes and sizes, so costs and services will differ tremendously. Here are the average costs and the primary services that you'll find from window installers.
How Much Do New Windows Cost?
Though the national average of installing a single window is about $600, it can range from $200 to $1,200. These estimates are based on the specifics of your installation, including number of windows, material, the location of your home, size, type and more.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Windham homeowners $435+ each year after replacing single-pane windows.
Something else that influences the total cost is the material of the frame you pick. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.
Full-frame installations entail replacing the full window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has significant deterioration. Full-frame installations are more involved and will increase the overall cost. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.
If you're still debating which type of installation to get, you can talk to your installer and get their advice. The choice mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Windham
EcoWatch is different from other reviewers, as we assess these companies through a sustainability lens. We have assessed the best window installation companies in Windham 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 electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Windham, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Windham.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, professionalism, warranty, quality of installation, quality of parts and more.
Cost
This one is a give-and-take: as with other services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies that provide 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 a good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Windham, NH Window Replacement FAQs
What is the typical cost to install new windows in a home?
The national average cost of replacing a window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is often 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 initially but can save you a decent amount of money a year in energy bills.
What type of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
Do I really have to use a window installation company?
Unless you have home repair skills and have all of the necessary tools to replace your own windows, we recommend hiring the pros. The process of installing windows is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer alternative.
How long does it take to install windows?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you have a lot of windows that have to be installed.
What time of year is a good time to replace my windows?
While you can install windows any time of year, warmer weather is often better for replacing windows. In addition, the weather should be dry, since rain can make the installation harder.
