How Installing Energy-Efficient Windows in Downers Grove Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to take the plunge and make the switch:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Downers Grove, that's about 449 pounds per year on average.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Better temperature control in your home: Energy-efficient windows can decrease how hard your heating system needs to work to heat your home.
Estimated Cost of Window Replacement in Downers Grove
Windows come in different shapes and sizes, so costs and services will vary tremendously. Here are the average costs and services that you'll find from the average window installation company.
How Much Do New Windows Cost?
According to our market research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. How much it will cost you varies based on several factors, like type, material, the location of your home, number of windows, size and more.
It's important to remember 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 Downers Grove homeowners $300+ a year when replacing single-pane windows.
We recommend requesting free quotes from multiple window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations are usually done when you want a new style or your window has significant rot. With this service, your professionals will replace the complete window, including the frame, trim and sill. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.
Your window installation company should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Downers Grove
In our search to find the most reliable, eco-friendly window installers in Downers Grove, the EcoWatch team chose the above companies as the best window installation companies in the city. We've decided to assess the best window installation companies in Downers Grove mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the Downers Grove area so you can find the right 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 featured in our guide to ensure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have positive feedback about their service from a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want 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 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 labor rank higher with EcoWatch.
Years of Experience
Because of Downers Grove's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Downers Grove window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Downers Grove, IL Window Replacement FAQs
What is the average cost to install new windows?
The national average cost of installing a single window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is often dependent on the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the best for energy efficiency?
A window's energy efficiency is influenced by a variety of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
Do I really need to use a window installation company?
Unless you have experience with home improvement projects and have all of the necessary tools to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved 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 much safer alternative.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, 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 more important than the temperature is that the weather should be dry.
How do you know it's time to replace your windows?
Windows generally last about 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have an expert take a look at them to see if they need any repairs or replacements.
