How Installing Energy-Efficient Windows in Windsor Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to consider making the switch:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Decrease your carbon footprint: In Windsor, you can lower your indirect greenhouse gas emissions by about 147 pounds per year when you switch to energy-efficient windows.
- Save on energy bills: Installing energy-efficient windows lowers your energy bills by about 12% since you use less energy.
Estimated Cost of Window Replacement in Windsor
Each window replacement company provides varying services and has different prices based on a few factors.
How Much Do New Windows Cost?
The national average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which carry a higher price tag.
Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $446 a year on your energy bills in Windsor.
We advise getting free quotes from several window companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
In general, there are two types of window installation services companies provide: full-frame and pocket installations.
Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your professionals will replace the whole window, including the sill, trim and frame. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're unsure which type of window installation service you should get, your installer can help you out. In general, the choice is influenced by 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 Windsor
In our hunt to find the most reliable, eco-friendly window installers in Windsor, EcoWatch examined dozens of companies before settling on these. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Windsor, we only included companies that cover the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Windsor.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer on this list to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, professionalism, cost, warranty, quality of installation and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Windsor's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Windsor window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Windsor, CT Window Replacement FAQs
How much does a window install cost?
The typical cost to replace one window can range between $450 and $650. There are a variety of factors that affect how much it costs, such as local labor costs, how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, your property's location and the number of windows.
Which type of window should I get?
Generally, double-pane windows are 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 that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
When do I need to use a window installation company?
You should use a window installation professional whenever you need to upgrade your windows. Installing windows is a complicated process that can be difficult to do on your own, so it's best left to the professionals.
What time of year is the best time to replace my 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 make sure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's probably time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
