How Installing Energy-Efficient Windows in St Louis Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In St Louis, that's about 763 pounds per year on average.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Save on electricity bills: Because energy-efficient windows lower the amount of energy used to heat or cool your home, the switch can help you save about $331 annually on your energy bills in St Louis.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in St Louis
When looking into window installation, each company offers different services and costs. Let's take a look at some typical costs and services.
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. These amounts vary based on the specifics of your installation, such as material, the location of your home, size, number of windows, type and more.
Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $331 a year on your energy bills in St Louis.
We advise requesting free quotes from multiple window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
If you're still trying to decide which type of installation to get, you can consult with your provider 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 St Louis
In our hunt to find the most reliable, eco-friendly window installers in St Louis, EcoWatch chose the above companies as the best window installation companies in the city. We've assessed the best window installers in St Louis mainly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for St Louis, 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 St Louis.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have good feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like 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 significant investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
St Louis, MO Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing one window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is typically dependent on the type and material of the window, the location of your property and the size of the window. 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 will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
If you're handy and know how to replace a window, it's possible to install your own windows. However, if you don't have the time or know-how, we don't recommend doing it on your own.
How long does it generally take to install windows?
Because a window takes about 30 minutes to install, around 16 windows can be installed in a typical 8-hour work day.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all of the windows together is the only way to gain that benefit. However, if you have just a few windows that are broken or drafty, you can replace just those.
