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• Protect your investment: When you have an older home, your windows could also be outdated or drafty.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.

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.

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.
