How Installing Energy-Efficient Windows in New Canaan Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could benefit you:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In New Canaan, that's about 147 pounds per year on average.
- Save on energy bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, they can help you save about $459 annually on your energy bills in New Canaan.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
Estimated Cost of Window Replacement in New Canaan
Windows come in varying styles, shapes and purposes, so costs and services will differ considerably based on your project. Below, we describe the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
The typical cost to install one window is about $600 but can range from $200 to $1,200. But costs will vary significantly based on the number of windows you need, the quality of your products, the current condition of your home and your location. A lot of window companies also offer door installations and other add-ons like baths, coating, shutters and more. Additional services will increase overall project costs.
It's important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save New Canaan homeowners $459+ a year when replacing single-pane windows.
We advise getting free quotes from multiple window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
Generally, there are two kinds of window installation services companies provide: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. It involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won't cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
Your window installation company can advise you on the best type for your project. In New Canaan, the decision will mostly be influenced by the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in New Canaan
EcoWatch reviews are different from most reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in New Canaan and ranked them using the following methodology:
Service Area
Because this is a guide for New Canaan, we gave more points to companies that provide services to 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
We're certain 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 technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why 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 quite some time. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
New Canaan, CT Window Replacement FAQs
What is the average cost to install windows?
The typical cost to replace one window can range from $450 to $650. There are many factors that influence the price, including the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are, your property's location, local labor costs and the number of windows.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes are casement windows, transom windows, picture windows, awning windows, bay windows, slider windows and double-hung and single-hung windows.
Can I install my own windows?
If you're handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don't have the time or skills, we don't recommend doing it on your own.
How long does it take to install windows?
Because the average installation time is 30 minutes per window, around 16 windows can be installed in an 8-hour work day.
What time of year is the best time to replace my windows?
Replacement windows can be installed any time of the year, 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 doesn't necessarily matter that much. What's most important is that the weather should be dry.
