Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home's efficiency can also have a considerable impact on home energy conservation. If your house has old or damaged windows, your HVAC system could be working overtime to heat or cool your house. This means spending more on electricity bills.
That's also bad news for the environment, as the extra energy required by old windows increases your carbon footprint.
Because windows have such a considerable impact on your home, selecting the best company for you is a big decision to make. That's why the EcoWatch team has put together this list of the best window replacement companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in East Hartford Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could help you:
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save $446 a year on your bills.
- Reduce your carbon footprint: By using less energy once you upgrade to energy-efficient windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- 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.
Estimated Cost of Window Replacement in East Hartford
Each window installer provides varying services and has different prices based on several factors.
How Much Do New Windows Cost?
According to our market research, the national average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. These figures vary depending on the specifics of your installation, such as material, type, the location of your home, number of windows, size and more.
It's important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save East Hartford homeowners $446+ a year when replacing single-pane windows.
Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.
A full-frame installation replaces the complete window, such as the sill, frame, trim and the window panes. As this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you're not sure which type of window installation service you need, your installer can help you out. In general, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in East Hartford
In our hunt to find the most reliable, eco-friendly window installers in East Hartford, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for East Hartford, we only included companies that cover the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in East Hartford.
Work Quality
When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you choose. 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 good things to say about their experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies are not going to provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
East Hartford, CT Window Replacement FAQs
How much does window installation cost?
The average cost of installing a single window ranges from $450 to $650. There are a variety of factors that influence the cost, which include the materials used in designing the windows, your property's location, the number of windows, how energy-efficient the windows are, styles and sizes of windows and local labor costs.
What type of window is the most energy-efficient?
A window's energy efficiency is influenced by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
Can you replace your own windows?
If you're handy and have experience with installing a replacement window, it's possible to install your own windows. But if you don't have the time or experience, we don't recommend it.
Should I replace all my windows at once?
If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
