How Installing Energy-Efficient Windows in East Hartford Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to make the switch:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In East Hartford, that’s about 147 pounds per year on average.
Estimated Cost of Window Replacement in East Hartford
Windows come in varying shapes and sizes, so costs and services will vary greatly. Here are the typical costs and the primary services that you’ll find from window installation companies.
How Much Do New Windows Cost?
According to our research, the average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 a window. These numbers vary depending on specific characteristics of your installation, like number of windows, type, size, material, the location of your home and more.
It’s also worth noting that energy-efficient windows will cost more upfront, but Energy Star predicts that switching out the windows on your East Hartford home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Another factor that affects the overall cost is the material of the frame you choose. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In regard to window installations, there are generally two types that your provider will offer: full-frame and pocket installations.
Full-frame installations entail replacing the full window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable damage or rot. Because these installations are more involved, they will raise the total cost. 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 rot or deterioration, you should opt for a full-frame installation instead.
Your window installer should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in East Hartford
In our search to make your home improvements easier and more eco-friendly in East Hartford, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured in our guide to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, professionalism, warranty, quality of parts, cost 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 providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to East Hartford’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of East Hartford window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
East Hartford, CT Window Replacement FAQs
What is the average cost to install new windows?
The average cost to install a window ranges from $450 to $650. There are several factors that influence how much it costs, including the materials used in designing the windows, how energy-efficient the windows are, the number of windows, local labor costs, styles and sizes of windows and your property’s location.
What are the kinds of windows?
There are several different types of windows you can get for your home, including picture windows, casement windows, slider windows, transom windows, awning windows, bay windows and double-hung and single-hung windows.
Can you replace your own windows?
Although you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window installation company can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your house, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.
