How Installing Energy-Efficient Windows in East Haven Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 147 pounds.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Installing energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
Estimated Cost of Window Replacement in East Haven
Windows come in different purposes, shapes and styles, so costs and services will vary tremendously depending on your project. Below, we go over the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
Although the average of replacing a single window is about $600, it can range from $200 to $1,200. How much it will cost varies depending on several factors, like number of windows, type, material, size, the location of your home and more.
It's important to keep in mind 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 Haven homeowners $522+ a year when replacing single-pane windows.
Asking for free quotes from multiple providers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. 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 damage or rot, you should opt for a full-frame installation instead.
Your window installer can help you figure out which type of installation you need.

How We Choose the Best Window Installers in East Haven
EcoWatch is different from most reviewers since we evaluate these companies through a sustainability lens. We've reviewed the best window replacement companies in East Haven mainly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window 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
We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including cost, professionalism, warranty, quality of parts, quality of installation and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a considerable investment, so you'll want to make sure that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to East Haven's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of East Haven window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
