Get matched with top window repair pros in Winthrop Harbor, IL

"The previous owner I bought the house from concealed the rotten windows and the home inspector my realtor recommended did not mention that the windows need to be replaced. 5 years later, water started to come into the house and I learned that not only I need windows, but my house susteined significant damage. I looked for a local company willing not only to replace the windows, but to fix the potential damage as much as possible. Not a same day or 2 days replacement company that will slap the new window in the rotten frame but someone willing to replace a rotten stud or seal. And I found Travis that made me an excellent impresaion- honest, knowledgeable and surprisingly, not pushy. After an initial quote I let it sit for about 2 weeks until I decided and except an email asking me if I have more questions...which I had -about 10 of them lol, he let me decide. In 4 weeks his team was already on site. Now his guys are the best. I had Adam and Rafal installing my windows and oh, my , when they opened the walls I was looking in disbelief at the rotten wood. They were able to replace all that rotten wood including wood studs, top and bottom seal, joists, etc and make the window casing look like new. Most companies either walk away or cover the rot but these guys were absolutely amazing. Every detail was adressed and every concern was answered. And I was not an easy customer because I was over concerned and watched everything they did, asking a bunch of questions. Yeah, that kind of a customer. What can I say. There are a lot of windows companies but these guys standed apart being able to handle this complex and challenging project. Highly recommended, a company that stands apart through the quality of work and professionalism."

"Recently had a cold draft coming in through the door that was installed in may of 2023, Because of the frigid weather we have been having we were unaware. I called the window guys and they came and fixed the problem. They honored their warranty of parts and labor. I will continue to tell my friends and family its a Company you can trust."

"I needed to replace a shattered 28X76 3/8" glass shower door and affix the side panel to prevent leaking. Damian was punctual and courteous, and he completed the work in the 1.5 hours that he predicted. He provided the best price of three installation quotes and did a beautiful job of installing the door and correcting an error of a fixed panel by the original installer. The new door and old panel match perfectly, the bathroom was clean when he left, the door works beautifully, and all leaking has stopped. I would definitely use him again."

"I had 7 new windows put in a rental property and they look incredible! Gus was tremendous throughout the whole process. He was very knowledgeable, highly experienced, and thoroughly explained any questions he answered of mine. I will definitely refer to friends and family."

"I recently had my window seal failures repaired, and the difference is night and day. Before the repair, I was dealing with foggy glass, drafts, and noticeable temperature fluctuations—especially during colder days. It not only looked bad but also made my home less comfortable and likely less energy efficient. The repair process was smooth and professional from start to finish. The work itself was completed efficiently, and Jon took care to keep everything clean and protected during the process. Now, my windows are crystal clear again, and the insulation has noticeably improved. There are no more drafts, and the rooms feel more consistent in temperature. It honestly feels like an upgrade to the entire house. If you’re dealing with failed window seals, I’d definitely recommend getting them repaired sooner rather than later—it makes a bigger difference than you might expect."

"Everyone was prompt, polite, and efficient. The Quality Manager set a convenient appointment for a quality review (couple of days after install). He found several minor things. He actually fixed a couple of items and had a crew out to fix the rest of the list two days later. This was a big process with 42 windows being capped or replaced."

"The owner came out same day we contacted him and did the repairs right then and there. Erik Went above and beyond and checked our entire roof for any other issues and did those repairs as well. Highly recommend Franos."

"The installers did a very good job without any mess. One window had a crack and one bad screen. These were fixed no questions asked."

"We want to thank Dominik for his expertise and advice when choosing our windows. We needed 12 original windows replaced, and he helped us choose windows that give the house a clean, refreshing look. He was very professional and explained the energy benefits we should expect to see."

"I recently had Real Seal do some repairs to a dock wall and lift a sidewalk at my work. From the first moment I contacted Real Seal they are nothing but professional. My first point of contact was Diane Schnieder. This lady is the best. When she came out to look at the scope of work, she told me yes indeed we can fix this. Then I mentioned a more complex repair on the leaning loading dock wall. Diane looked it over and said we can fix it. They have already repaired the sidewalk, and they are coming back out to repair the leaning dock wall. This company is totally awesome."
