How Installing Energy-Efficient Windows in New Haven Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to make the switch:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that number, which helps you save $541 a year on your bills.
- Reduce your carbon footprint: In New Haven, you can reduce your indirect greenhouse gas emissions by about 147 pounds per year after you switch to energy-efficient windows.
Estimated Cost of Window Replacement in New Haven
When looking into window installation, each company offers different services and costs. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
On average, New Haven homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at around $600. How much it will cost depends on several factors, such as size, the location of your home, type, number of windows, material and more.
Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
We advise getting free quotes from several window installers to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?
A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. Because this type of installation is more involved, it will be more expensive than a pocket installation. A pocket installation entails installing a new window within the existing frame. So, instead of taking 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 will be able to help you understand what's best for your needs. In New Haven, the decision will mostly depend on how old your home is and if there's any moisture damage. Wood can decay if not maintained properly over the years, so it's a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in New Haven
In our search to make your home improvements easier and more eco-friendly in New Haven, EcoWatch chose the above companies as the top window installation companies in the city. We've decided to assess the top window installation companies in New Haven mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for New Haven, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in New Haven.
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 company featured on this list to ensure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have good feedback about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers won't always provide the most quality service. Still, we want to ensure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, 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 been in the industry for quite some time. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
New Haven, CT Window Replacement FAQs
What is the average cost to install windows in a home?
The typical cost to install a window ranges from $450 to $650. There are many factors that influence the price, which include styles and sizes of windows, how energy-efficient the windows are, local labor costs, your property's location, the number of windows and the materials used in designing the windows.
Which kind of window should I get?
A window's energy efficiency is affected by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
Can you install 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 job is done properly and that you can avoid spending the time and effort of doing it yourself.
What time of year should I replace my windows?
Replacement windows can be installed during any season, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
How do you know it's time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
