How Installing Energy-Efficient Windows in East Haven Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how switching out your windows could benefit you:
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
- Save on energy bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll require less energy to heat or cool your home.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Decrease your carbon footprint: By using less energy after you upgrade to energy-efficient windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in East Haven
Windows come in all shapes and sizes, so costs and services will vary considerably. Here are the typical costs and the primary services that you’ll find from window installers.
How Much Do New Windows Cost?
Typically, homeowners in East Haven can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. These estimates vary depending on specific characteristics of your installation, such as material, the location of your home, type, number of windows, size and more.
It’s also worth keeping in mind that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your East Haven home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Asking for free quotes from several companies is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two types of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails replacing a window without taking out the whole frame, which tends to be cheaper than a full-frame installation.
Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in East Haven
The EcoWatch Reviews team is different from most reviewers, as we’re examining these companies through a sustainability lens. We have evaluated the top window installers in East Haven mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for East Haven, we gave more points to companies that cover the city. There are certainly reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in East Haven.
Work Quality
When installing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you choose. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, cost, professionalism, quality of parts, quality of installation and more.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
East Haven, CT Window Replacement FAQs
What is the average cost to install windows?
The national average cost of replacing a window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What type of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies do?
Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
How often do you need to replace windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
