How Installing Energy-Efficient Windows in West Hartford Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 147 pounds.
- Save money on energy bills: Since energy-efficient windows reduce the amount of energy used to heat or cool your home, they can help you save around $446 annually on your energy bills in West Hartford.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
Estimated Cost of Window Replacement in West Hartford
Windows come in different purposes, shapes and styles, so costs and services will vary tremendously depending on your project. Below, we detail the typical cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
On average, homeowners in West Hartford can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost at around $600. Costs will vary significantly based on the quality of your products, the number of windows you need, your location and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.
It's important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save West Hartford homeowners $446+ a year when replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first question to ask yourself when getting new windows is: Do you want a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the total window. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation means replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
Your window installation company should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in West Hartford
EcoWatch differs from most reviewers since we look at these companies through a sustainability lens. We have assessed the top window replacement companies in West Hartford mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for West Hartford, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in West Hartford.
Work Quality
When picking new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type 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
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have nice feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want 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 with 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
West Hartford, CT Window Replacement FAQs
What is the typical cost to install new windows?
The national average cost of installing one window is around $600 but can range from $200 to $1,200, based on several factors. The price is generally influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which type of window is the best?
A window's energy efficiency depends on several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Can you install your own windows?
Although it is possible to install your own windows, doing so requires a lot of time and handiness. 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.
How often should you replace your windows?
Windows typically last about 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them checked by an expert to see if they are in need of a repair or replacement.
