How Installing Energy-Efficient Windows in Stonington Saves You Money

When you switch to energy-efficient windows, you may see some benefits, such as:

  • Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 147 pounds.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
  • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save $424 a year on your bills.

Estimated Cost of Window Replacement in Stonington

Windows come in all shapes and sizes, so costs and services will differ remarkably. Here are the typical costs and services that you'll find from the average window installation company.

How Much Do New Windows Cost?

According to our research, the typical cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which carry a higher price tag.

Keep in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates 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 you install double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Getting free quotes from multiple providers is the best way to find out which one is right for you.

What Services do Window Installers Offer?

The first step of a window installation is to figure out whether you want a full-frame or pocket installation.

A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. Because this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations are simpler and won't carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

Your window installation company should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Stonington

In our hunt to find the most reliable, eco-friendly window installers in Stonington, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We have reviewed the top window installers in Stonington mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve Stonington so you can find a quality window installation company near you.

Work Quality

When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If most customers don't have nice feedback about their service from a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window companies may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum 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 make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Stonington, CT Window Replacement FAQs

What is the average cost to replace windows?

The average cost to install one window can range from $450 to $650. There are many factors that affect how much it costs, including your property's location, styles and sizes of windows, the materials used in designing the windows, how energy-efficient the windows are, the number of windows and local labor costs.

Which type of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. If you want to be sure you'll have 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.

Can you replace your own windows?

If you're handy and know how to replace a window, it's possible to install your own windows. However, if you don't have the time or skills, we recommend hiring a professional.

How long does it typically take to install windows?

Because a window takes about 30 minutes to install, around 16 windows can be installed during an 8-hour work day.

What time of year is the best time to replace my windows?

Even though you can install windows any time of year, warmer weather is typically better for installing replacement windows. Additionally, it shouldn't be raining, since rain can make the installation more difficult.
