How Installing Energy-Efficient Windows in Oak Lawn Saves You Money
When you switch to energy-efficient windows, you may see several perks, such as:
- Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of household energy use. Switching to energy-efficient windows can help decrease that number, which helps you save more on your bills.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty.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 value.
- Decrease your carbon footprint: In Oak Lawn, you can cut your indirect greenhouse gas emissions by about 449 pounds per year after you install energy-efficient windows.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Oak Lawn
Let’s take a look at the cost of window installation and the types of services offered by installers.
How Much Do New Windows Cost?
Even though the typical cost to install one window is around $600, it can range anywhere from $200 to $1,200. How much it will cost is based on several factors, including material, type, number of windows, the location of your home, size and more.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Oak Lawn homeowners $295+ per year after replacing single-pane windows.
We recommend requesting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
When considering window replacements, in general there are two kinds that your provider will have: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which increase the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window within the existing frame, which is generally cheaper than a full-frame installation.
Your window installation company will be able to help you figure out what’s best for your needs. In Oak Lawn, the decision will mostly depend on how old your windows are and if there’s any moisture damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Oak Lawn
In our hunt to find the most reliable, eco-friendly window installers in Oak Lawn, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. We’ve assessed the best window installation companies in Oak Lawn mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Oak Lawn so you can find the right window installation company near you.
Work Quality
When choosing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, cost, warranty, professionalism and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you 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 installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Oak Lawn, IL Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost to install one window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically 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 most energy-efficient?
A window’s energy efficiency is affected by a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
When do I need to use a window installation company?
Unless you have home repair skills and have the time to replace your own windows, we recommend hiring a professional installer. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer option.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
