Why you can trust EcoWatch

Fortunately, saving you energy with more efficient windows also helps our goals of conserving energy and the resources it takes to make it.
Unlike other review sites, EcoWatch ranks window companies based on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in West Hartford Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to take the plunge and make the switch:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Better temperature control in your home: When you live in a place like West Hartford where the winters can be very cold, you often need to rely on your heater to keep your house warm. Energy-efficient windows can lower how hard your heater needs to work to heat your home.
- Decrease your carbon footprint: In West Hartford, you can reduce your indirect greenhouse gas emissions by about 147 pounds per year after you upgrade to energy-efficient windows.
Estimated Cost of Window Replacement in West Hartford
Each window installation company offers varying services and has varying prices depending on a few factors.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range from $200 to $1,200. But costs will vary significantly based on the current condition of your home, the quality of your products, the number of windows you need and your location. A lot of window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. Additional services will increase your overall project costs.
With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save West Hartford homeowners $446+ per year after replacing single-pane windows.
Getting free quotes from multiple installers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
In regard to window installations, there are generally two types that your installer will offer: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot. With this service, your installers will replace the total window, including the trim, sill and frame. 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.
What are the most common types of replacement windows?
The most common kinds of windows for homes include: awning windows, bay windows, transom windows, casement windows, picture windows, slider windows and double-hung and single-hung windows.
What services do window replacement companies offer?
Window installers travel to your property to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is done.
What time of year is a good time to replace my windows?
Replacement windows can be installed during any season, but autumn might be best. Regardless of 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 more important than the temperature is that the weather should be dry.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, it's most likely time to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
