How Installing Energy-Efficient Windows in Glen Ellyn Saves You Money
When you switch to energy-efficient windows, you may see several benefits, such as:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on electricity bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save around $300 annually on your energy bills in Glen Ellyn.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in Glen Ellyn
Each window replacement company provides varying services and has different costs based on several factors.
How Much Do New Windows Cost?
According to our research, the national average cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. But costs will vary considerably based on the quality of your products, the number of windows you need, your location and the current condition of your home. Many window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.
It’s also worth keeping in mind that energy-efficient windows will typically cost more initially, but Energy Star predicts that switching out the windows on your Glen Ellyn 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. The amount of money you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Something else that affects the overall cost is the material of the frame you select. Aluminum frames are typically the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question 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 full window, such as the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations are simpler and won’t carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.
Your window installation company should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Glen Ellyn
EcoWatch is different from most reviewers because we evaluate these companies through a sustainability lens. We have decided to assess the best window installers in Glen Ellyn primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Glen Ellyn, we only included companies that cover the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Glen Ellyn.
Work Quality
When picking new windows, the quality and breadth 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 factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, cost, quality of parts, quality of installation, warranty and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a sizable investment, so you’ll want to make sure 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
Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Glen Ellyn, IL Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing one window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is often influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the kinds of windows?
There are several different kinds of windows you can get for your house, such as double-hung and single-hung windows, picture windows, slider windows, casement windows, bay windows, transom windows and awning windows.
What services do window replacement companies offer?
Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the house, so the temperature outside doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.
How often should you replace windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
