How Installing Energy-Efficient Windows in Clayton Saves You Money

There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

  • Save money on energy bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you'll use less energy to heat or cool your home.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
  • More efficient energy usage in your household: Because the winters can get very cold in Clayton, homeowners usually rely on their heater during that time. Energy-efficient windows cut back on how much heat is lost through your windows, making it easier to keep your home warm.

Estimated Cost of Window Replacement in Clayton

When looking into window installation, each company offers different services and prices. Let's look at some typical costs and services.

How Much Do New Windows Cost?

Although the average of replacing one window is around $600, it can range from $200 to $1,200. These estimates are based on specific characteristics of your installation, such as the location of your home, number of windows, type, material, size and more.

It's important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Clayton homeowners $376+ a year when replacing single-pane windows.

Another factor that influences the overall cost is the material you choose for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step of a window replacement is to think about whether you want a full-frame or pocket installation.

A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window within the frame that's already there. So, instead of taking out the whole unit and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company should be able to help you understand what's best for your needs. In Clayton, the decision will mostly depend on the age of your home and if there's any moisture damage. Wood can decay if it's 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 Clayton

EcoWatch is different from most reviewers because we're examining these companies through a sustainability lens. We have evaluated the top window replacement companies in Clayton mostly 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 can cut your power 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 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 looking for a company to do a great job installing windows. We've vetted each installer featured in our guide to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have nice things to say about their service from a certain window installation company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a spectrum 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

Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Clayton, MO Window Replacement FAQs

How much does window installation cost?

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

What type of window is the most energy-efficient?

A window's energy efficiency depends on several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

Can I replace my own windows?

Even though it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window replacement company can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

How long does window installation typically 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 need to have a lot of windows installed.
