How Installing Energy-Efficient Windows in Affton Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Save on power bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll require less energy to heat or cool your house.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 763 pounds per year on average.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Affton
Let's take a look at the cost of window replacement and the types of services offered by installers.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. Costs will vary considerably based on the current condition of your home, the quality of your products, your location and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. Additional services will increase overall project costs.
It's also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your Affton home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are usually the most expensive, though it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?
A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation entails installing a new window within the old frame. This means instead of removing the whole window and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're hiring a reputable window installation company, your company can advise you on the best type for your project. In Affton, the decision will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Affton
EcoWatch reviews are different from most reviews because we're examining these companies through a sustainability lens. We have reviewed the top window installers in Affton mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce 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 Affton, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Affton.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company in our guide to ensure its technicians are well-qualified and that the company has received plenty 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 positive things to say about their experience with 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 most quality service. On the other hand, we want to make sure 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. For that reason, 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 experience earn higher rankings by our standards. We like to see at least ten years of experience.
Affton, MO Window Replacement FAQs
How much should a window install cost?
The average cost to replace a single window can range from $450 to $650. There are many factors that influence the cost, which include styles and sizes of windows, the materials used in designing the windows, local labor costs, how energy-efficient the windows are, the number of windows and your property's location.
What kind of window is the most energy-efficient?
A window's energy efficiency depends on several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
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 the pros. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer alternative.
How often should you replace windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
Should I replace my windows all at the same time?
If you're upgrading your windows to get more efficient windows, replacing all the windows at once is the only way to gain that benefit. On the other hand, if you have just a few windows that are damaged or drafty, you can replace just those.
