Why you can trust EcoWatch
A review of the best window installation companies in Southington may not seem like the most compelling article on the EcoWatch site, but trust us, windows have a more direct impact on your life than you might think. The Department of Energy estimates that heat gained or lost through outdated or drafty windows could make up about 30% of heating and cooling costs. In Southington, where the energy bills are an average of $36 per month, that's almost $$129 per year wasted.
That's also bad news for the environment, as the additional energy used by drafty windows increases your carbon footprint.
Efficient windows are especially important in Southington, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $446 a year.

How Installing Energy-Efficient Windows in Southington Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to consider making the switch:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Save on electricity bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $446 annually on your energy bills in Southington.
Estimated Cost of Window Replacement in Southington
Each window replacement company offers varying services and has different prices depending on a few factors.
How Much Do New Windows Cost?
According to our market research, the average cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. How much it will cost depends on several factors, like type, number of windows, size, material, the location of your home and more.
It's also worth bearing in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Southington home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
Full-frame installations entail replacing the total window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot or deterioration. Because full-frame installations are more involved, they will increase the overall cost. A pocket installation involves replacing a window within the existing frame, which is usually less expensive than a full-frame installation.
Your window installation company can recommend the best type for your project. In Southington, the decision will mostly be influenced by the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Southington
EcoWatch is different from other reviewers, as we're examining these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the Southington area so you can find the best window installation company near you.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company in our guide to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, warranty, professionalism, quality of installation, cost and more.
Cost
This one is a give-and-take: similar to other services, cheap window installers are not going to provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a sizable 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 been in the industry for a while. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Southington, CT Window Replacement FAQs
What is the average cost to install new windows?
The average cost to replace one window ranges between $450 and $650. There are a variety of factors that affect how much it costs, such as styles and sizes of windows, local labor costs, the materials used in designing the windows, the number of windows, how energy-efficient the windows are and your property's location.
What type of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
Even though it is possible to install your own windows, doing so requires a lot of time and handiness. Using a window replacement company can help ensure that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but autumn might be best. 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 the home, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
When is it time to replace your windows?
Windows generally last about 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have an expert take a look at them to determine if they are in need of a repair or replacement.
