How Installing Energy-Efficient Windows in Carol Stream Saves You Money
By upgrading to energy-efficient windows, you and your family can benefit in several ways, such as:
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Carol Stream, that’s about 449 pounds per year on average.
- Save on electricity bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $300 annually on your energy bills in Carol Stream.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Carol Stream
Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
Generally, homeowners in Carol Stream can anticipate that most window installations will cost between $250 and $1,200, with the average cost sitting at about $600. This is because the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.
It’s also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your Carol Stream home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
We recommend getting free quotes from multiple window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
When considering window replacements, in general there are two kinds that your provider will offer: full-frame and pocket installations.
Full-frame installations entail replacing the complete window, including the sill, trim and frame. Full-frame installations are necessary when you want a new style or your window has significant damage or rot. Because these installations are more involved, they will increase the total cost. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company should be able to help you choose what’s best for your needs. In Carol Stream, the decision will mostly be based on how old your windows are and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Carol Stream
EcoWatch is different from most reviewers, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
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 contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good feedback about their experience with a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers won’t always provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you’ll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor 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 installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Carol Stream, IL Window Replacement FAQs
What is the typical cost to install windows in a home?
The national average cost of installing a single window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is generally 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 a decent amount of money a year in energy bills.
What kind of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies offer?
Window installers cover the entire process — from replacing old windows with brand-new ones to cleaning up after the windows have been put in place. Additionally, some companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, it shouldn’t be raining, because rain can make the installation more difficult.
How often do you need to replace windows?
Windows usually have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them checked by an expert to determine if they are in need of a repair or replacement.
