How Installing Energy-Efficient Windows in East Lyme Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, such as:
- Save money on energy bills: Once you upgrade to 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 home.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
- More efficient energy usage in your household: Because the winters can get very cold in East Lyme, homeowners often depend on their heater during that time. Energy-efficient windows lower how much heat is lost through your windows, making it easier to keep your house warm.
Estimated Cost of Window Replacement in East Lyme
Let's go over the cost of window replacement and the types of services offered by installers.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200. This is because window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.
Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will typically cost more than other windows, but on the other hand, you can save about $424 a year on your energy bills in East Lyme.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two types of window installation services companies provide: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant rot. With this service, your professionals will replace the full window, including the sill, frame and trim. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you're still trying to decide which type of installation to get, you can consult with your installer and get their advice. The decision 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 East Lyme
EcoWatch reviews are different from other reviews because we look at these companies through a sustainability lens. We've assessed the best window installation companies in East Lyme mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the East Lyme area so you can find a quality window installation company near you.
Work Quality
When picking new windows, the quality and range of services often plays 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
We analyzed trends in recent customer feedback to determine the companies with the most consistent 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, quality of installation, warranty, quality of parts and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven 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.
East Lyme, CT Window Replacement FAQs
How much should a window install cost?
The national average cost of installing a window is about $600 but can range between $200 and $1,200, depending 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, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll get 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.
What services do window installation companies provide?
Window installation professionals cover the entire process — from replacing old windows with brand new ones to cleaning up after the windows have been put in place. In addition, a lot of companies offer window manufacturing, customization and repairs.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
