Why you can trust EcoWatch
Although eco-friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house’s efficiency can also have a big impact on home energy conservation. The Department of Energy estimates that heat gained or lost through old or damaged windows could be responsible for nearly 30% of heating and cooling usage. In Torrington, where the energy bills are an average of $36 per month, that’s almost $$129 per year wasted.
That’s also bad for the environment, as the additional energy required by old windows increases your carbon footprint.
Because windows are so important for your home, selecting the best company for you is a big decision to make. That’s why the EcoWatch team has curated this list of the top window replacement companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in Torrington Saves You Money
There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Reduce your carbon footprint: In Torrington, you can lower your indirect greenhouse gas emissions by about 147 pounds per year when you install energy-efficient windows.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Save 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 $486 annually on your energy bills in Torrington.
Estimated Cost of Window Replacement in Torrington
Let’s take a look at the cost of window replacement and the kinds of services offered by installers.
How Much Do New Windows Cost?
On average, homeowners in Torrington can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. Costs will differ significantly based on the current condition of your home, your location, the number of windows you need and the quality of your products. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.
It’s also worth bearing in mind that energy-efficient windows will usually cost more initially, but Energy Star predicts that switching out the windows on your Torrington home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We recommend requesting free quotes from several window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. As this kind of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.
If you’re not sure which type of window installation service you should get, your installer can assist you. Typically, the choice is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Torrington
EcoWatch reviews are different from most reviews, as we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state 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 a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured on this list to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, professionalism, cost, quality of installation, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies won’t always provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a significant investment, so you’ll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Torrington, CT Window Replacement FAQs
What is the average cost to replace windows in a home?
The typical cost of replacing a window ranges between $450 and $650. There are many factors that influence the price, which include your property’s location, the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are, local labor costs and the number of windows.
What are the most common types of replacement windows?
The most common types of windows for homes are bay windows, double-hung and single-hung windows, picture windows, casement windows, transom windows, awning windows and slider windows.
Can I install my own windows?
Even though you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the job is done properly and that you won’t have to spend the time and effort to do it yourself.
What time of year is a good time to replace my windows?
While you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, the weather should be dry, since rain can make the installation more difficult.
When is it time to replace your windows?
Windows generally have a lifespan of around 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 determine if they are in need of a repair or replacement.
