How Installing Energy-Efficient Windows in East Lyme Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to consider making the switch:
- Save money on power bills: Installing energy-efficient windows lowers your energy bills by about 12% since you need less energy.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In East Lyme, that's about 147 pounds per year on average.
Estimated Cost of Window Replacement in East Lyme
Windows come in all shapes and sizes, so costs and services will differ greatly. Here are the typical costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
The national average cost to install one window is about $600 but can range from $200 to $1,200. But costs will vary considerably based on the number of windows you need, your location, the quality of your products and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.
It's important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save East Lyme homeowners $424+ a year when replacing single-pane windows.
We advise requesting free quotes from multiple window installers to find the right windows and the company that works best for you.
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.
What are the most common kinds of replacement windows?
There are various kinds of windows you can get for your house, including awning windows, bay windows, slider windows, picture windows, transom windows, casement windows and double-hung and single-hung windows.
When should I use a window installation company?
You should hire a window installation professional whenever you need new windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best handled by the professionals.
How long does window installation generally take?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all your windows together is the only way to see a noticeable difference. On the other hand, if you have only a few windows that are damaged or drafty, you can replace just those.
