How Installing Energy-Efficient Windows in Windsor Locks Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could benefit you:
- Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 147 pounds per year on average.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on electricity bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $446 annually on your energy bills in Windsor Locks.
Estimated Cost of Window Replacement in Windsor Locks
Windows come in different shapes, purposes and styles, so costs and services will differ greatly 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?
Generally, Windsor Locks homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at about $600. But costs will vary significantly based on the current condition of your home, your location, the number of windows you need and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.
Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $446 a year on your energy bills in Windsor Locks.
Something else that affects the total cost is the material you pick for your frame. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
Generally, there are two types of window installation services companies offer: full-frame and pocket installations.
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 damage or rot. Because full-frame installations are more involved, they will increase the overall cost. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company can help you choose which type of installation you need.

How We Choose the Best Window Installers in Windsor Locks
In our hunt to find the most reliable, eco-friendly window installers in Windsor Locks, EcoWatch chose the above companies as the best window installation companies in the city. We've reviewed the top window installers in Windsor Locks primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
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 a quality window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, professionalism, cost, quality of installation, quality of parts 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 points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Windsor Locks, CT Window Replacement FAQs
How much does window installation cost?
The typical cost to install one window ranges between $450 and $650. There are many factors that affect the price, including styles and sizes of windows, your property's location, local labor costs, how energy-efficient the windows are, the materials used in designing the windows and the number of windows.
What kind of window is the most energy-efficient?
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're getting 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 offer?
Window installation professionals travel to your property to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How long does window installation typically take?
Each window takes around 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
What time of year is a good time to replace my windows?
Replacement windows can be installed at any time, 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 house, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
