Why you can trust EcoWatch
A guide on the best window installation companies in Westport may not seem like the most compelling article on the EcoWatch site, but trust us, windows have a more direct impact on your life than you might realize. Outdated windows can cost you in energy bills. In fact, the Department of Energy estimates that 25-30% of your home’s heat or cool air could be lost through your windows.
That’s also bad for the environment, as the additional energy required by drafty windows increases your carbon footprint.
As windows have such a large impact on your home, selecting the best company for you is a big decision to make. That’s why the EcoWatch team has created this list of the top window replacement companies, so you can more easily make an informed decision.

How Installing Energy-Efficient Windows in Westport Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could help you:
- Save on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 147 pounds.
Estimated Cost of Window Replacement in Westport
Windows come in various shapes and sizes, so costs and services will differ remarkably. Here are the average costs and the primary services that you’ll find from the average window installation company.
How Much Do New Windows Cost?
Although the national average cost to replace one window is around $600, it can range anywhere from $200 to $1,200. Costs will vary considerably based on the current condition of your home, the quality of your products, the number of windows you need and your location. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.
It’s also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Westport home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We recommend getting free quotes from multiple window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
In regard to window replacements, in general there are two types that your provider will offer: full-frame and pocket installations.
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails replacing a window without replacing the frame. So, instead of taking out the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can help you choose which type of installation you need.

How We Choose the Best Window Installers in Westport
In our search to make your home improvements easier and more eco-friendly in Westport, the EcoWatch Reviews team assessed dozens of companies before settling on these. We have evaluated the top window installers in Westport primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Westport, we gave more points to companies that cover the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Westport.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer in our guide to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including cost, professionalism, quality of parts, warranty, quality of installation and more.
Cost
This one is a give-and-take: as with most services, cheap window companies won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Westport’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Westport window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Westport, CT Window Replacement FAQs
How much should a window install cost?
The national average cost to replace a single window is around $600 but can range between $200 and $1,200, depending on several factors. The price is typically dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the most common types of replacement windows?
There are various types of windows you can get for your home, such as casement windows, awning windows, bay windows, slider windows, double-hung and single-hung windows, picture windows and transom windows.
What services do window replacement companies provide?
Window installation companies cover the entire process — from replacing old windows with brand-new ones to cleaning up after the installation. In addition, some companies offer window manufacturing, customization and repairs.
Should I replace all my windows at once?
If your windows are more than 20 years old, it’s probably time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
How long does it usually take to install windows?
Since the average installation time is 30 minutes per window, around 16 windows can be installed during a typical 8-hour work day.
