How Installing Energy-Efficient Windows in East St. Louis Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- 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 Older homes usually have windows that are outdated, drafty or potentially even damaged in some way.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 home if you decide to sell.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of residential energy use. Switching to energy-efficient windows can help decrease that number, which helps you save $316 a year on your bills.
Estimated Cost of Window Replacement in East St. Louis
Windows come in all shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
Though the typical cost of installing one window is about $600, it can range from $200 to $1,200. But prices vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which will add extra costs to your project.
It’s important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save East St. Louis homeowners $316+ a year when replacing single-pane windows.
We advise getting free quotes from multiple window installation companies to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step when planning a replacement is to figure out whether you should get a full-frame or pocket installation.
A full-frame installation replaces the full window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations are simpler and won’t cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you’re still debating which type of installation to get, you can consult with your provider and get their advice. The decision mostly depends on how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in East St. Louis
EcoWatch reviews are different from most reviews since we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the East St. Louis area so you can find the best window installation company near you.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company in our guide to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, quality of installation, cost, professionalism, warranty and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to East St. Louis’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of East St. Louis window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
East St. Louis, IL Window Replacement FAQs
What is the average cost to install new windows in a home?
The typical cost of installing a single window can range from $450 to $650. There are several factors that influence how much it costs, including your property’s location, the materials used in designing the windows, how energy-efficient the windows are, the number of windows, local labor costs and styles and sizes of windows.
What are the types of windows?
There are various kinds of windows you can get for your home, such as bay windows, awning windows, picture windows, slider windows, casement windows, transom windows and double-hung and single-hung windows.
Do you really need to use a window installation company?
Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional installer. The process of installing windows is complex 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.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it’s most likely time to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
