How Installing Energy-Efficient Windows in Stamford Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how switching out your windows could help you:
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: By using less energy once upgrading to energy-efficient windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
- 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: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
Estimated Cost of Window Replacement in Stamford
Windows come in various shapes, purposes and styles, so costs and services will vary tremendously depending on several factors. Below, we describe the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. These estimates vary based on the specifics of your installation, such as number of windows, size, material, the location of your home, type 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 per year when you install single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Another factor that affects the total cost is the material you pick for your frame. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which increase the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.
If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Stamford, the decision will mostly depend on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Stamford
EcoWatch is different from other reviewers, as we evaluate these companies through a sustainability lens. We’ve assessed the best window replacement companies in Stamford mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Stamford, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Stamford.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have good things to say about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you’ll want to be certain 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 a proven track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Stamford, CT Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost to install one window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is typically influenced by the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
There are several different types of windows you can get for your house, including picture windows, awning windows, slider windows, double-hung and single-hung windows, casement windows, bay windows and transom windows.
Can you install your own windows?
While it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window replacement company can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to 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.
Should I replace all my windows at once?
If you’re upgrading your windows to get more efficient windows, replacing all the windows at once is the only way to see a noticeable difference. However, if you have just a few windows that are broken or leaky, you can replace just those.
