How Installing Energy-Efficient Windows in Windham Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch are the following:
- More efficient energy usage in your home: Because the summers can get pretty warm in Windham, homeowners usually depend on their air conditioner during that time. Energy-efficient windows lower how much cool air is lost through your windows, making it easier to keep your house cool.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of household energy use. Installing energy-efficient windows can help decrease that number, which helps you save $396 a year on your bills.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
- Better temperature control in your home: When you reside in a city like Windham where the winters can get cold, you often have to depend on your heater to keep your home warm. Energy-efficient windows can reduce the amount of heat lost through your windows when heating your home.
Estimated Cost of Window Replacement in Windham
Each window installer provides varying services and has different costs based on a few factors.
How Much Do New Windows Cost?
On average, Windham homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at approximately $600. How much it will cost you is based on several factors, including material, type, number of windows, size, the location of your home and more.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material you pick for your window frames. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first step when considering a replacement is to think about whether you should get a full-frame or pocket installation.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations are simpler and won't carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.
Your window replacement company will be able to help you figure out what's best for your needs. In Windham, the decision will mostly be based on the age of your home and if there's any moisture damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Windham
The EcoWatch Reviews team is different from other reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Windham area so you can find the right window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you get. 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
Customer feedback is another super important review factor. If the majority of customers don't have nice things to say about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a substantial 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
Due to Windham's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Windham window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
