How Installing Energy-Efficient Windows in Southington Saves You Money
When you switch to energy-efficient windows, you may see a few perks, including:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
- Save on electricity bills: Since energy-efficient windows lower the amount of energy used to heat or cool your home, they can help you save about $446 annually on your energy bills in Southington.
- More efficient energy usage in your home: Because the winters can get very cold in Southington, homeowners often rely on their heater during that time. Energy-efficient windows cut back on how much heat is lost through your windows, making it easier to keep your home warm.
Estimated Cost of Window Replacement in Southington
Windows come in varying shapes, styles and purposes, so costs and services will differ remarkably based on several factors. Below, we go over the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
Though the national average of replacing one window is around $600, it can range from $200 to $1,200. How much it will cost varies based on several factors, such as the location of your home, number of windows, size, type, material and more.
It's important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Southington homeowners $446+ a year when replacing single-pane windows.
Asking for free quotes from several installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first thing to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant damage. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installer can help you choose which type of installation you need.

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.
When do I have to use a window installation company?
You should hire a window installation professional whenever you want new windows. Installing windows is a complex process that can take a lot of time, so it's best handled by the professionals.
How do you know it's time to replace your windows?
Windows generally last 20 to 30 years, but anytime you see damage on your windows, it's a good time to have them checked by an expert to see if they need any repairs or replacements.
