How Installing Energy-Efficient Windows in Clayton Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are some reasons you may want to consider making the switch:
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Clayton, that's about 763 pounds per year on average.
- Save money on energy bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save about $376 annually on your energy bills in Clayton.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in Clayton
Windows come in all shapes and sizes, so costs and services will vary greatly. Here are the typical costs and the primary services that you can find from window installers.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. Costs will differ significantly depending on the current condition of your home, the number of windows you need, the quality of your products and your location. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.
It's important to keep in mind that windows with higher 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 Clayton homeowners $376+ a year when replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. 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 with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
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 are the different types of windows?
The most common types of windows for homes include: double-hung and single-hung windows, casement windows, awning windows, picture windows, bay windows, transom windows and slider windows.
When should I use a window installation company?
Unless you have experience with home improvement projects and have all the tools you need to replace your own windows, we recommend hiring a professional. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and safer option.
What time of year should I replace my windows?
Though you can install windows any time of year, warmer weather is often better for installing replacement windows. Additionally, the weather should be dry, since rain can make the installation harder.
How often should you replace windows?
Windows typically last around 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have an expert take a look at them to see if they need any repairs or replacements.
