How Installing Energy-Efficient Windows in North Stonington Saves You Money
When you switch to energy-efficient windows, you may see a few perks, including:
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that number, which helps you save $424 a year on your bills.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 147 pounds.
Estimated Cost of Window Replacement in North Stonington
Windows come in different purposes, shapes and styles, so costs and services will vary tremendously based on several factors. Below, we describe the average cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
Typically, homeowners in North Stonington can expect that most replacement window installations will cost between $250 and $1,200, with the average cost at about $600. Costs will differ significantly depending on your location, the quality of your products, the number of windows you need and the current condition of your home. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save North Stonington homeowners $424+ per year after replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
When it comes to window installations, in general there are two kinds that your installer will offer: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has a great amount of rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
Your window installation company can help you choose which type of installation you should get.

How We Choose the Best Window Installers in North Stonington
In our hunt to find the most reliable, eco-friendly window installers in North Stonington, EcoWatch examined many companies before settling on these. We have evaluated the best window installation companies in North Stonington primarily based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for North Stonington, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in North Stonington.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included in our guide to make sure its contractors are well-qualified and that the company has gotten plenty 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 most other categories, including professionalism, warranty, cost, quality of parts, quality of installation and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. Still, we want to make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of North Stonington's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of North Stonington window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
North Stonington, CT Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost to install a window is around $600 but can range from $200 to $1,200, based on several factors. The price is generally influenced by 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 initially but can save you a decent amount of money a year in energy bills.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
When do I have to use a window installation company?
You should hire a window installation professional whenever you want to replace your windows. Installing windows is a complex process that can be difficult to do on your own, so it's best handled by the professionals.
How long does it typically take to install windows?
Each window takes about 30 minutes to install based on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
How often should you replace your windows?
Windows usually have a lifespan of 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to determine if they are in need of a repair or replacement.
