How Installing Energy-Efficient Windows in West Hartford Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Protect your valuables from fading: When you upgrade 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.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
- Save money on power bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
Estimated Cost of Window Replacement in West Hartford
Windows come in various shapes and sizes, so costs and services will vary tremendously. Here are the average costs and the primary services that you can find from the average window installation company.
How Much Do New Windows Cost?
According to our research, the national average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which have a higher price tag.
It’s also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that upgrading the windows on your West Hartford home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
When considering window installations, in general there are two types that your installer will have: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant deterioration. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company should be able to help you understand what’s best for your needs. In West Hartford, the decision will mostly be based on the age of your windows and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in West Hartford
The EcoWatch Reviews team differs from other reviewers because we evaluate these companies through a sustainability lens. We’ve evaluated the best 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 Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for West Hartford, we only included companies that serve the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in West Hartford.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don’t have positive things to say about their experience with a certain window installation company, it won’t be featured on EcoWatch.
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 previously, windows are a considerable 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
Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
