How Installing Energy-Efficient Windows in New Fairfield Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Save money on electricity bills: Since energy-efficient windows lower the amount of energy used to heat or cool your home, they can help you save around $441 annually on your energy bills in New Fairfield.
Estimated Cost of Window Replacement in New Fairfield
Let's take a look at the cost of window replacement and the types of services offered by installers.
How Much Do New Windows Cost?
On average, homeowners in New Fairfield can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at around $600. How much it will cost varies depending on several factors, including size, number of windows, type, material, the location of your home and more.
It's also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star predicts that upgrading the windows on your New Fairfield home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Getting free quotes from several installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
When it comes to window installations, there are generally two types that your installer will have: full-frame and pocket installations.
Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your installers will replace the full window, including the trim, sill and frame. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window replacement company will be able to help you understand what's best for your needs. In New Fairfield, the decision will mostly be based on how old your home is and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in New Fairfield
In our hunt to find the most reliable, eco-friendly window installers in New Fairfield, the EcoWatch team chose the above companies as the best window installation companies in the city. We've reviewed the top window installation companies in New Fairfield primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve New Fairfield so you can find the right window installation company near you.
Work Quality
When installing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, professionalism, cost, quality of parts, warranty and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a sizable investment, so you'll want to make sure that investment is well protected. Window installation companies that have 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 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.
New Fairfield, CT Window Replacement FAQs
What is the typical cost to install new windows?
The average cost to install a single window ranges between $450 and $650. There are many factors that influence how much it costs, such as how energy-efficient the windows are, your property's location, local labor costs, the materials used in designing the windows, the number of windows and styles and sizes of windows.
What are the types of windows?
There are various kinds of windows you can get for your home, including double-hung and single-hung windows, casement windows, slider windows, picture windows, bay windows, transom windows and awning windows.
Do you really need to use a window installation company?
Unless you have home repair skills and have the time to replace your own windows, we recommend hiring a professional installer. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and much safer alternative.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. 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 isn't necessarily a big factor. Most importantly, the weather should be dry.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
