20 Best Window Companies in Lisle, IL (2025 Reviews)

How Installing Energy-Efficient Windows in Lisle Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to think about making the switch:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
• Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 449 pounds per year on average.
• Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.

Estimated Cost of Window Replacement in Lisle

Windows come in various purposes, styles and shapes, so costs and services will differ remarkably based on your project. Below, we describe the average cost and services that you’ll find from window replacement companies.

How Much Do New Windows Cost?

Typically, Lisle homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at around $600. But costs will vary significantly depending on the current condition of your home, the quality of your products, the number of windows you need and your location. Many window companies also offer door installations and other add-ons like shutters, coating, baths and more. These extra services will increase overall project costs.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lisle homeowners $300+ per year after replacing single-pane windows.

We advise requesting free quotes from several window installers to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

The first thing to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?

A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which raise 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 around the window after a full-frame installation. A pocket installation involves replacing a window without replacing the frame. So, instead of taking out the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to advise you on the best type for your project. In Lisle, the decision will mostly be influenced by how much damage there is currently and the age of your existing frames.

Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including professionalism, quality of installation, quality of parts, warranty, cost and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

As discussed previously, windows are a substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
