Why you can trust EcoWatch
A guide on the best window replacement companies in Lake St Louis may not seem like the most interesting article on the EcoWatch site, but trust us, windows have more of an impact on your life than you might think.

How Installing Energy-Efficient Windows in Lake St Louis Saves You Money
When you switch to energy-efficient windows, you may see a few perks, including:
- Save money on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll require less energy to heat or cool your home.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Lake St Louis, that's about 763 pounds per year on average.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Lake St Louis
Windows come in all shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and services that you can find from window installation companies.
How Much Do New Windows Cost?
The typical cost to install one window is about $600 but can range anywhere from $200 to $1,200. This is because of the fact that window installations depend on several factors specific to your home, including 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 predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
Getting 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?
The first step when planning a window installation is to clarify whether you need a full-frame or pocket installation.
Full-frame installations are usually recommended when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the complete window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installer can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Lake St Louis
In our hunt to find the most reliable, eco-friendly window installers in Lake St Louis, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. We've decided to review the best window installers in Lake St Louis mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Lake St Louis area so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice feedback about their service from a certain company, it won't be featured on EcoWatch.
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 gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a sizable investment, so you'll want to make sure that investment is well protected. Window installation companies with 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 a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Lake 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 several factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
There are various kinds of windows you can get for your house, such as slider windows, awning windows, bay windows, double-hung and single-hung windows, casement windows, transom windows and picture windows.
Can you replace your own windows?
Even though you can install your own windows, doing so is time-consuming and requires a lot of 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.
When is it time to replace your windows?
Windows generally last about 20 to 30 years, but anytime you see damage on your windows, it's a good time to have an expert take a look at them to see if they are in need of a repair or replacement.
