Window Concepts, Inc. has been a family-owned staple of the Chicago Suburbs since 1982. With over 43 years of local history, we provide homeowners with a dedicated focus on professional window installation. While windows are our primary specialty, our team maintains the expertise and skills to handle full-service roofing, siding, and door projects as secondary exterior solutions. We are a team of career installers, not a manufacturer. This allows us to offer an objective selection of products specifically suited for the Illinois climate, including high-durability Vinyl, custom-crafted Wood, weather-resistant Fiberglass, and specialized Egress window solutions. As an Angi Approved PRO and A+ BBB Accredited business, we rely on our decades of local service and precision-focused installation to ensure every home we touch is secure and energy-efficient.

"Our home is 85 years old and was in need of extensive renovations. We chose Window Concepts for our windows, roofing, and siding, and they did an outstanding job! Garrett provided a wide range of samples and made the entire process smooth and convenient. My wife and I highly recommend this family-owned company—they truly stand out! Their customer service is also exceptional and very accessible; 10/10 experience!"

Founded in 1996, J & K has held quality workmanship at its core from the very beginning. We started as a exterior restoration company with 5 employees. We were small, but we knew that if we worked hard and stayed true to our quality we would be successful in the long run. In 2005, responding to huge demand, we started working as a General Contractor. The dedication to quality, strong work ethic and great customer service continued to be our hallmark. Over the years we have grown and learned to never forget the ethics that have guided us. Today we find the marketplace more competitive than ever before. The rapidly rising cost of materials, fuel and labor make surviving in our industry more and more difficult. Unfortunately the result is a high failure rate of businesses in our market. J & K Home Improvement offers the highest quality materials available and backs our workmanship with a ten year limited warranty.

"Simply put, you will NOT find a better, more honest, more helpful, more easy-to-work-with, reasonably priced contractor than John Lee and his crew at J & K Home Improvement & Restoration! We had a "complicated" set of circumstances when our home was damaged by a storm, last winter. The insurance company sent out an estimator to assess the damage and, after the company recommended J & K Home Improvement & Restoration, I was introduced to John Lee. I eventually learned that John also does estimates for a variety of insurance companies (because his company is so well regarded), and he patiently listened as I described the nuances associated with our house. During our initial consultation, he was able to clearly describe all of the steps that would be necessary and answer all of our questions. Long story short, not only was John able to address EVERY single concern and request that we had regarding the eventual repairs to the house (including roof, siding, and a window upgrade that would have cost much more if we had done it at a later time), but he spent plenty of extra time making sure that everything we had talked about was addressed to our 100% satisfaction! He was also able to persuade the insurance company to cover more complete repairs than was originally specified by the first adjuster! In addition, when we had an electrical "hiccup" associated with all the pounding on the walls, John quickly sent an expert electrician to locate and correct the problem. He absolutely could have passed those charges on to us because the failure wasn't due to any mistake on the part of his crew but, instead, he picked up the unanticipated expense himself. It was truly a pleasure to work with John! He made a difficult situation as easy to manage as possible, and we would strongly recommend J & K Home Improvement & Restoration to anyone who wants to hire a quality contractor that stands behind their work and well-earned reputation!"

Windows questions, answered by experts

It’s easy to tell if you have low-E windows. Light a match or grab a pen light and hold it up to your windows. You should see multiple reflections in the window—four for double-pane windows. If one of the reflections is a slightly different color than the other three, you have low-E windows. If you don’t have low-E windows, all the reflections will be the same color.

When it comes to your pocket, opting for energy-efficient windows can lead to an average of 12% in energy bill savings. That totals to yearly energy savings between $100 and $600. However, the exact amount you’ll save hinges on factors like your local climate and the number of windows in your home.

Folding window installation costs about $1,600 on average, ranging from $500 to $3,000. The cost factors of this project include the size, the type of folding windows, the number of panels, and the type of glass. Different types of folding windows include:

  • Standard folding window: $200 per linear foot

  • Glazed folding window: $240 per linear foot

  • Standard folding window and swing door: $1,000 per linear foot

  • Folding window and sliding door: $2,000 per linear foot

Double-pane windows increase your home’s energy efficiency, leading to lower energy bills and more comfortable temperatures inside. They also dramatically reduce noise from outside compared to single-pane windows, so you’ll notice your home is significantly quieter once you’ve installed double-pane windows. If you’re replacing your windows, the initial investment in double-pane styles can be well worth the up-front cost.

According to the U.S. Department of Energy, low-E windows can reduce energy loss by 30% to 50%. But the actual effect of low-E windows in your home will depend on many factors, like climate, number of windows, window treatments, and more. In terms of aesthetics, you may or may not notice a difference in how your windows look or how much natural light shines through. But overall, low-E windows look very similar to traditional windows.
