How Installing Energy-Efficient Windows in Prospect Heights Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to consider making the switch:
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Save on energy bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your home.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Prospect Heights, that’s about 449 pounds per year on average.
Estimated Cost of Window Replacement in Prospect Heights
Windows come in various shapes and sizes, so costs and services will vary greatly. Here are the average costs and services that you’ll find from the average window installation company.
How Much Do New Windows Cost?
Though the average cost of installing a single window is around $600, it can range from $200 to $1,200. How much it will cost varies based on several factors, including type, material, size, the location of your home, number of windows and more.
It’s important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Prospect Heights homeowners $295+ a year when replacing single-pane windows.
How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler 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 installation company will be able to recommend the best type for your project. In Prospect Heights, the decision will mostly be influenced by how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Prospect Heights
In our search to make your home improvements easier and more eco-friendly in Prospect Heights, the EcoWatch team evaluated dozens of companies before settling on these. We’ve reviewed the best window installation companies in Prospect Heights mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Prospect Heights, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Prospect Heights.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company included on this list to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don’t have good feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.
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 awarded higher points 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 that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Prospect Heights, IL Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost of installing a single window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is usually dependent on the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
There are several different kinds of windows you can get for your house, such as picture windows, awning windows, double-hung and single-hung windows, slider windows, bay windows, transom windows and casement windows.
What services do window replacement companies provide?
Window installers visit your property to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on your energy bills, replacing all your windows at once is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or leaky, you can replace just those.
