How Installing Energy-Efficient Windows in Waterford Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Decrease your carbon footprint: By using less energy once switching to energy-efficient windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of residential energy use. Installing energy-efficient windows can help lower that amount, which helps you save $424 a year on your bills.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Waterford
Windows come in various shapes, styles and purposes, so costs and services will vary tremendously based on several factors. Below, we detail the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Even though the typical cost of installing one window is about $600, it can range from $200 to $1,200. But costs will vary significantly depending on the quality of your products, your location, the number of windows you need and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.
It’s also worth keeping in mind that energy-efficient windows will cost more upfront, but Energy Star estimates that switching out the windows on your Waterford home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
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 provide poor insulation. Vinyl frames are a bit more expensive and provide 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 provide decent insulation for your home.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable rot. These installations are more involved and will raise the overall cost. 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 should opt for a full-frame installation instead.
If you’re not sure which type of window installation service you need, your installer can advise you. Typically, the decision depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Waterford
In our search to find the most reliable, eco-friendly window installers in Waterford, EcoWatch evaluated many companies before landing on these. Along with energy efficiency, we reviewed window companies all across the state and ranked them using the following methodology:
Service Area
Since this is a guide for Waterford, we paid more attention to companies that serve the city. There are certainly reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Waterford.
Work Quality
When installing 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 choose. We do rate window installers higher if they offer high-quality products, but we also factor in 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, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, cost, quality of parts, professionalism, warranty 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 ensure we’re highlighting companies that provide a 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. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Waterford, CT Window Replacement FAQs
What is the typical cost to install windows?
The typical cost of replacing one window ranges between $450 and $650. There are many factors that affect the cost, such as your property’s location, local labor costs, how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows and the number of windows.
What type of window is the most energy-efficient?
A window’s energy efficiency is influenced by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
Do I really have to use a window installation company?
You should use a window installation professional whenever you want new windows. Installing windows is a complex process that can take a lot of time, so it’s best left to the professionals.
What time of year should I replace my windows?
Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your home, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
How long does window installation take?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
