Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although clean energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home’s efficiency can also have a large impact on home energy conservation. Potential leaks or drafts from your windows can make your home uncomfortable in the summer or winter.

That’s also bad news for the environment, as the additional energy required by leaky windows increases your carbon footprint.

Efficient windows are especially important in Southbury, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $420 each year.

How Installing Energy-Efficient Windows in Southbury Saves You Money

When you upgrade to energy-efficient windows, you may see a few perks, including:

  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
  • Save money on electricity bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll require less energy to heat or cool your home.

Estimated Cost of Window Replacement in Southbury

Let’s go over the cost of installing new windows and the types of services you may need for your home.

How Much Do New Windows Cost?

According to our research, the national average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. This is because the cost of window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

It’s important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Southbury homeowners $420+ a year when replacing single-pane windows.

Another factor that affects the overall cost is the material of the frame you select. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

In general, there are two kinds of window installation services companies provide: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve other materials, such as insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame 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 installer can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Southbury

In our hunt to find the most reliable, eco-friendly window installers in Southbury, the EcoWatch team chose the above companies as the top window installation companies in the city. We’ve decided to review the best window replacement companies in Southbury primarily based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Southbury, we only included companies that provide services to the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Southbury.

Work Quality

When choosing new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window you opt for. 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 positive things to say 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 most services, cheap window companies won’t always provide the highest quality service. On the other hand, 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 considerable investment, so you’ll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor 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 installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Southbury, CT Window Replacement FAQs

How much does window installation cost?

The typical cost of replacing a window can range from $450 to $650. There are many factors that affect how much it costs, which include the materials used in designing the windows, the number of windows, your property’s location, how energy-efficient the windows are, local labor costs and styles and sizes of windows.

What type of window is the most energy-efficient?

Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.

What services do window replacement companies do?

Window installers travel to your house to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.

How long does window installation take?

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