How Installing Energy-Efficient Windows in Waterbury Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways switching out your windows could benefit you:

  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Better temperature control in your home: Energy-efficient windows can lower the amount of heat lost through your windows when heating your home.
  • Save on energy bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.

Estimated Cost of Window Replacement in Waterbury

Let's go over the cost of updating your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

Generally, homeowners in Waterbury can expect that most replacement window installations will range from $250 to $1,200, with the average cost sitting at about $600. This is because of the fact that window installations are based on several factors specific to your home, including 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 upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Waterbury homeowners $420+ a year when 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 using 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?

The first thing to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the complete window, including the sill, trim and frame. Pocket installations are simpler and won't carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

If you're still trying to decide which type of installation you should get, you can talk to your installer and get their recommendation. The decision mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Waterbury

EcoWatch reviews are different from other reviews, as we look at these companies through a sustainability lens. We've decided to evaluate the top window replacement companies in Waterbury mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

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 on this list to ensure its technicians are well-qualified and that the company has gotten tons 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, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including cost, quality of installation, warranty, quality of parts, professionalism and more.

Cost

This one is a give-and-take: similar to other services, cheap window installers won't always provide the highest quality service. On the other hand, 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. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Waterbury's climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Waterbury window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Waterbury, CT Window Replacement FAQs

How much does window installation cost?

The national average cost to replace one window is around $600 but can range between $200 and $1,200, based on several factors. The price is usually influenced by the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What kind of window is the most energy-efficient?

Generally, double-pane windows will be 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're getting the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.

Can you replace your own windows?

While you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help ensure that the installation is done properly and that you won't have to spend the time and effort to do it yourself.

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

Though you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, it shouldn't be raining, since rain can make the installation more difficult.
