How Installing Energy-Efficient Windows in East Lyme Saves You Money
When you upgrade to energy-efficient windows, you may see a few benefits, such as:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if your home is on the older side.
- Decrease your carbon footprint: In East Lyme, you can lower your indirect greenhouse gas emissions by about 147 pounds per year when you switch to energy-efficient windows.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Save money on power bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save around $424 annually on your energy bills in East Lyme.
Estimated Cost of Window Replacement in East Lyme
Each window installation company provides varying services and has varying price points based on several factors.
How Much Do New Windows Cost?
Typically, homeowners in East Lyme can expect that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. This is because window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $424 a year on your energy bills in East Lyme.
How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. A pocket installation entails replacing a window within the existing frame. So, instead of tearing out the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can recommend the best type for your project. In East Lyme, the decision will mostly be influenced by how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in East Lyme
The EcoWatch Reviews team differs from other reviewers since we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:
Service Area
Because this is a guide for East Lyme, we only included companies that provide services to the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in East Lyme.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included on this list to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, quality of installation, professionalism, warranty, quality of parts and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we awarded higher scores 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 give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of East Lyme’s climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of East Lyme window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
