Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home’s efficiency can also have a considerable impact on home energy conservation. Drafty, leaky windows can cost you in energy bills. As a matter of fact, the Department of Energy estimates that about 30% of your house’s heat or cool air could be lost through your windows.
Installing energy-efficient windows on your property can help you save money each month on your energy bills — and you can help the environment as well.
Efficient windows are particularly important in Fairfield, where summers are long and hot. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $640 each year.

How Installing Energy-Efficient Windows in Fairfield Saves You Money
When you switch to energy-efficient windows, you may see a few benefits, such as:
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Fairfield, that’s about 117 pounds per year on average.
- Save on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Fairfield
Windows come in varying shapes, styles and purposes, so costs and services will vary tremendously depending on your project. Below, we go over the typical cost and services that you’ll find from window installers.
How Much Do New Windows Cost?
Typically, homeowners in Fairfield can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. But prices differ considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which will add extra costs to your project.
It’s important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Fairfield homeowners $640+ a year when replacing single-pane windows.
We recommend getting free quotes from multiple window installation companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step when considering a window replacement is to figure out whether you want a full-frame or pocket installation.
A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which raise the overall 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 (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can recommend the best type for your project. In Fairfield, the choice will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Fairfield
The EcoWatch Reviews team is different from most reviewers because we look at these companies through a sustainability lens. We’ve assessed the best window installers in Fairfield mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Fairfield, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Fairfield.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer in our guide to ensure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don’t have nice feedback about their service from a certain company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers may not provide the highest quality service. Still, we want to make sure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Fairfield’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Fairfield window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
