How Installing Energy-Efficient Windows in Rockton Saves You Money
By switching to energy-efficient windows, you can take advantage of several benefits, including:
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your carbon emissions. You could reduce it by 449 pounds per year on average.
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
- Save money on energy bills: Once you switch 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.
Estimated Cost of Window Replacement in Rockton
Each window installation company offers various services and has different prices based on several factors.
How Much Do New Windows Cost?
Although the national average cost of installing a single window is around $600, it can range anywhere from $200 to $1,200. How much it will cost is based on several factors, such as size, material, type, number of windows, the location of your home and more.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Rockton homeowners $318+ a year after replacing single-pane windows.
Asking for free quotes from multiple installers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which increase the total cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves installing a new window within the frame that’s already there. So, instead of tearing out the whole unit and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to help you decide what’s best for your needs. In Rockton, the decision will mostly be based on how old your windows are and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Rockton
EcoWatch reviews differ from other reviews, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Rockton and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Rockton area so you can find a quality 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 installer featured in our guide to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including cost, professionalism, quality of installation, quality of parts, warranty and more.
Cost
This one is a give-and-take: as with most services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Rockton, IL Window Replacement FAQs
What is the typical cost to replace windows?
The national average cost of replacing one window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is generally influenced by 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 a decent amount of money a year in energy bills.
What type of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.
Do I really have to use a window installation company?
You should hire a window installation professional whenever you need new windows. Installing windows is a complicated process that can take a lot of time, so it’s best handled by the professionals.
Should I replace all my windows at once?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
How long does window installation generally take?
Since the average installation time of a window is 30 minutes, around 16 windows can be installed during a typical 8-hour work day.
