How Installing Energy-Efficient Windows in Sterling Saves You Money

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

  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save on energy bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save about $457 annually on your energy bills in Sterling.
  • Better temperature control in your home: When you reside in a place like Sterling where the winters can get very cold, you usually have to rely on your heater to keep your house warm. Energy-efficient windows can reduce how much heat is lost through your windows when heating your home.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.

Estimated Cost of Window Replacement in Sterling

Windows come in varying styles, purposes and shapes, so costs and services will vary considerably based on several factors. Below, we go over the typical cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

The typical cost to replace a single window is about $600 but can range from $200 to $1,200. This is because window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.

Bear 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 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.

Requesting free quotes from several companies is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

There are generally two types of window replacement services: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the frame, sill and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable rot. Full-frame installations are more involved and will increase the overall cost. Pocket installations are on the simpler end 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 or rot, you may need a full-frame installation instead.

Your window replacement company will be able to help you figure out what's best for your needs. In Sterling, the decision will mostly be based on the age of your windows and if there's any damage. Wood can decay if not properly maintained over the years, so it's good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Sterling

EcoWatch differs from most reviewers since we're examining these companies through a sustainability lens. We have assessed the best window installers in Sterling mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Sterling, we gave more points to companies that serve the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Sterling.

Work Quality

When installing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you opt for. 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 highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of installation, cost, professionalism, quality of parts, warranty and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies that provide 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 a good track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Sterling, CT Window Replacement FAQs

How much does window installation cost?

The national average cost of installing a window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which type of window should I get?

Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification — this means they're certified energy-efficient by the U.S. Department of Energy.

Do I really have to use a window installation company?

Unless you have experience with home improvement projects and have all of the necessary tools to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and safer alternative.

How often do you need to replace your windows?

Windows usually have a lifespan of about 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have them looked at by an expert to determine if they are in need of a repair or replacement.
