"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."

"From the very beginning I was thoroughly pleased with everyone I worked with, Salesman, window removal and re-installation of new windows by craftsman and everyone involved! If I had a question concerning the contract or installation questions, all were answered in a timely manner to me by my Salesman, Steve Churma. He was well versed in the product as well as all of the procedures necessary for this project and that was truly appreciated. I would recommend this company to anyone that might require new windows at any time."

"I hired Fox Window Tints to remove and replace the window tint in my master bathroom. When they arrived they quickly realized the old adhesive was very strong and a huge pain to remove. Despite this, the team kept a very positive attitude and very diligently removed every piece of pesky old window tint. I love the end result and will definitely hire them again! Thank you!"

"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

"One of the few honest service providers out there. Having researched many of the providers and contacted many, I highly recommend anyone with flooding issues call and get RealSeal's opinion before proceeding. RealSeal solved my basement flooding issues at a fraction of the cost (unlike other providers who try to sell you an entire system whether you need it or not). They have very honest sales people and provided great service. Our house had previously had basement flooding and seepage issues. I knew the cause of the flooding and had a fair sense of where the seepage was coming from and my home remodeling contractors (who gutted my basement) had a similar view on the source of flooding and seepage. Every service provider I called tried to sell me some huge draintile system and sump system that was an exorbitantly costly, unnecessary and overkill solution. Real Seal were the only guys who came in and were completely honest in terms of where the seepage was coming from - under the windows and a few cracks in the wall (actually created by the cable guys); their thoughts were consistent with what I had seen over the last decade in the house and what my contractors thought. They sealed all the cracks and reinforced and sealed around the windows on my gutted basement at a fraction of the cost. We have had close to 9 months to observe (incl before refinishing the basement) and absolutely no water despite many storms that would have previously brought in water."

Windows FAQs, answered by experts

While some homeowners are under the impression that triple-pane windows can help to reduce sound, the truth is that triple-pane windows will not be much quieter than double-pane windows since having a third pane doesn’t make much difference in sound transmission. If you’re looking to reduce sound, you should consider installing laminated glass windows.

Yes, you can create a solution of dish soap and hot water to create a cleaning solution. You’ll want to mix about one to two drops of dish soap for every 8 ounces of hot water. If you use too much soap, it’ll create too many suds and make it harder to effectively wash away.

Awning windows are just like hopper windows except that they open the opposite way. Instead of opening inward, awning windows open outward with a hinge at the top. This creates a mini-awning within your window frame, which is where the name comes from. Hopper windows, on the other hand, open inward with a hinge at the bottom.

The average lifespan for a casement window is around 20 years, but some higher-end casement windows with more durable frame materials can last up to around 40 years before you need to replace them. You’ll need to carry out routine maintenance and window cleaning—and, on occasion, casement window restoration—to extend the lifespan of your casement windows. But they tend to wear more slowly than windows with sliding sashes because the weatherstripping sees minimal friction.

Well water can leave ugly marks on your window. A vinegar-water spray will remove most well water stains from your windows. However, you can also use a baking soda paste if the stain is too stubborn. Consider applying waterproofing protection to the glass surface after cleaning for long-term protection. A protective film or spray layer also makes it easier to remove the water stains next time.
