How Installing Energy-Efficient Windows in East Haddam Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, including:
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
- Reduce your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you'll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Replacing your windows with energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in East Haddam
Windows come in varying styles, shapes and purposes, so costs and services will differ remarkably based on your project. Below, we describe the typical cost and services that you'll find from window installers.
How Much Do New Windows Cost?
Although the typical of replacing one window is around $600, it can range anywhere from $200 to $1,200. These numbers vary based on the specifics of your installation, including material, the location of your home, type, size, number of windows and more.
With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save East Haddam homeowners $460+ a year after replacing single-pane windows.
We recommend getting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
The first step when planning a window replacement is to figure out whether you need a full-frame or pocket installation.
Full-frame installations entail replacing the complete window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable rot. Full-frame installations are more involved and will increase the overall cost. A pocket installation involves installing a new window without replacing the frame. So, instead of taking out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in East Haddam
In our hunt to make your home improvements easier and more eco-friendly in East Haddam, EcoWatch landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty 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
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company featured on this list to ensure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, quality of installation, cost, professionalism, warranty and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as 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 serious investment, so you'll want to be certain 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
Because of East Haddam's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of East Haddam window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
East Haddam, CT Window Replacement FAQs
How much does a window install cost?
The average cost of replacing one window can range between $450 and $650. There are many factors that influence the cost, such as how energy-efficient the windows are, styles and sizes of windows, your property's location, the number of windows, the materials used in designing the windows and local labor costs.
Which type of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies do?
Window installation professionals go to your home to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
How long does it usually take to install windows?
Each window takes around 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, 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 the house, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
