"Chicago Window Guys provided me with 8 replacement windows in my condo unit. The windows were fitted very well, and they were able to remove my old windows and install my new windows in a very timely manner. In addition, they were able to replace windows on the fourth floor of my building, while many other companies I contacted were not willing or able to do so! The warranty they provide with their windows also provides great peace of mind."

"F and A were fantastic! Just as advertised, when we called, one of the co-owners picked up. They came over to our house same-day and gave an estimate for gutter cleaning, and indoor and/or outdoor window cleaning. We had them clean the outside of the windows and the gutters. They spent over 2 hours thoroughly cleaning, and the windows have never looked better!"

Windows FAQs, answered by experts

Window security film won’t prevent break-ins or stop your window from shattering from impact during extreme weather like hurricanes or tornadoes. However, applying security film is relatively inexpensive, and it can make breaking into your home significantly harder—often hard enough to deter burglars entirely—and keep your window from shattering on your floor after impact. For these reasons, window security film is often a worthwhile investment that helps protect your property.

There are many high-quality window companies on the market, although Andersen, Pella, and Marvin continue to be the most popular nationwide. Some brands, like Sunrise and Soft-Lite, are popular regionally but may not be available in all parts of the United States. When comparing brands, look for features like increased energy efficiency, strong and durable materials, and long-lasting and all-encompassing warranties.

Bay and bow windows can increase the value of a home. These window styles not only enhance a home's aesthetic appeal by adding architectural interest and increasing natural light but also create additional interior space for seating or decorative purposes. The added functionality and visual appeal can make a home more attractive to potential buyers, potentially leading to a higher resale value. However, the impact on home value depends on various factors, including the overall condition of the home, local real estate market trends, and the quality of the window installation.

Yes, replacing windows can boost your home’s resale value by improving its curb appeal, energy efficiency, and comfort. The return on investment (ROI) varies depending on the types of windows you install, but most homeowners see an ROI of around 60% to 70% of the cost of the window installation, according to the Remodeling 2024 Cost vs. Value Report. 

One of the best professional cleaning solutions that won’t leave streaks is one gallon of distilled or bottled water mixed with 2 to 4 teaspoons of dish soap. Apply using a sponge in a figure-eight motion, and then use a squeegee to remove the majority of the water and soap. You can finish drying with a piece of old black-and-white newspaper to remove any residue for a streak-free clean every time.
