Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's energy efficiency can also have a big impact on home energy conservation. Drafty or leaky windows can cut your home's energy efficiency by up to 30%, according to the Department of Energy. In Stafford, that's about $437 per year that you could save on your power bills after making the switch.
That's also bad news for the environment, as the additional energy used by outdated windows increases your carbon footprint.
We've made this guide on the best installation companies to help you in your search, so you can not only enjoy brand new windows, but also save money on your electricity bills.

How Installing Energy-Efficient Windows in Stafford Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to consider making the switch:
- Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 147 pounds per year on average.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save on power bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of household energy use. Upgrading to energy-efficient windows can help lower that amount, which helps you save some money on your bills.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Stafford
Each window installer provides various services and has varying prices depending on a few factors.
How Much Do New Windows Cost?
Typically, homeowners in Stafford can expect that most window installations will range from $250 to $1,200, with the average cost sitting at around $600. This is because window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.
It's important to note that windows with higher 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 Stafford homeowners $437+ a year when replacing single-pane windows.
Another factor that affects the total cost is the material you pick for your frame. Aluminum frames are usually the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because 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?
In general, there are two kinds of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your professionals will replace the total window, including the frame, trim and sill. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Stafford
EcoWatch reviews differ from most reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for Stafford, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Stafford.
Work Quality
When picking new windows, the quality and range of services often plays just as important of a role in insulation 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
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of parts, warranty, cost, professionalism, quality of installation and more.
Cost
This one is a give-and-take: as with other services, cheap window installers won't always 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
As discussed, windows are a substantial investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Stafford's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Stafford window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Stafford, CT Window Replacement FAQs
How much should a window install cost?
The average cost of installing a single window can range between $450 and $650. There are many factors that affect how much it costs, such as styles and sizes of windows, the materials used in designing the windows, your property's location, how energy-efficient the windows are, local labor costs and the number of windows.
What are the kinds of windows?
There are various types of windows you can get for your home, such as casement windows, transom windows, picture windows, bay windows, awning windows, double-hung and single-hung windows and slider windows.
What services do window replacement companies offer?
Window installation companies will do the entire process — from replacing old windows with brand new ones to cleaning up after the installation. Additionally, a lot of companies offer window manufacturing, customization and repairs.
What time of year is a good 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 ensure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
When is it time to replace your windows?
Windows usually last around 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have an expert take a look at them to see if they are in need of a repair or replacement.
