How Installing Energy-Efficient Windows in New Canaan Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Upgrading to energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- Reduce your carbon footprint: In New Canaan, you can reduce your indirect greenhouse gas emissions by about 147 pounds per year when you upgrade to energy-efficient windows.
Estimated Cost of Window Replacement in New Canaan
Let's go over the cost of updating your windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
According to our market research, the average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. These figures are based on specific characteristics of your installation, like number of windows, the location of your home, type, material, size and more.
Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Asking for free quotes from several providers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
Full-frame installations are necessary when you want a new style or your window has a lot of rot. With this service, your installers will replace the total window, including the sill, trim and frame. A pocket installation entails replacing a window within the old frame. So, instead of removing the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In New Canaan, the decision will mostly be influenced by how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in New Canaan
EcoWatch is different from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in New Canaan and ranked them using the following methodology:
Service Area
Since this is a guide for New Canaan, we only included companies that cover the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in New Canaan.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also consider 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 positive things to say about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installers won't always provide the most quality service. On the other hand, 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
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of New Canaan's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of New Canaan window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
New Canaan, CT Window Replacement FAQs
What is the average cost to install new windows in a home?
The typical cost to install a window ranges from $450 to $650. There are a variety of factors that affect the cost, such as local labor costs, how energy-efficient the windows are, styles and sizes of windows, the number of windows, the materials used in designing the windows and your property's location.
What are the most common kinds of replacement windows?
There are various kinds of windows you can get for your home, including double-hung and single-hung windows, bay windows, awning windows, picture windows, slider windows, transom windows and casement windows.
What do window installers do?
Window installation professionals travel to your property to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How long does window installation typically take?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed in a typical 8-hour work day.
How do you know it's time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
