How Installing Energy-Efficient Windows in St Charles Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could help you:
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
- Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in St Charles
Windows come in various purposes, shapes and styles, so costs and services will differ greatly based on several factors. Below, we describe the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
According to our research, the national average cost of replacing a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost depends on several factors, such as type, the location of your home, size, material, number of windows and more.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save St Charles homeowners $297+ a year after replacing single-pane windows.
We advise requesting free quotes from several window installers to find the one that works best for you.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Do you need a full-frame installation or a pocket installation?
A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. A pocket installation means replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
If you're still debating which type of installation you need, you can consult with your provider and get their recommendation. The choice mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in St Charles
In our search to make your home improvements easier and more eco-friendly in St Charles, EcoWatch landed on the above companies as the best window installation companies in the city. We have evaluated the best window installation companies in St Charles mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for St Charles, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in St Charles.
Work Quality
When choosing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have nice feedback about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
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 installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, 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.
St Charles, IL Window Replacement FAQs
How much should window installation cost?
The national average cost of installing one window is around $600 but can range between $200 and $1,200, depending on several factors. The price is usually dependent on 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.
Which kind of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
How long does it take to install windows?
Because the average installation time is 30 minutes per window, about 16 windows can be installed during an 8-hour work day.
What time of year is the best time to replace my windows?
While you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, the weather should be dry, as rain can make the installation harder.
