Get matched with top basement waterproofing pros in Carol Stream, IL

"After living in our house for 20 years, we had seepage for the first time in one part of our basement. We called several waterproofing places that morning and ULB was by far the most responsive. The same day we called, Stoyan came out to see the leak, diagnose the cause, and propose a fix. Stoyan did an excellent job at explaining the problem and scheduling the repair. Within two days, Kyle came to fill the crack. His work was also excellent. Stoyan and Kyle both came to our house at the times promised and were very good at answering the questions we had. We were very impressed with ULB and highly recommend them."

"Ever seal did a fantastic job figuring out what my problem was, quoting a decent price and fixing my problem. I highly recommend them for wAterproofing; I'm only sorry I didn't call them earlier."

"We had our basement waterproofed last year and were very happy. This year's project was adding two support beams. Again, we were very happy with the quality of the work and the people we dealt with. Both Gunnar and his team and Perfecto were skilled, efficient, and very professional. Highly recommend."

"Luis was professional from scheduling the free quote, scheduling the work, and getting the work done. He answered all of my questions and prepared a detailed plan and estimate. A pleasure to work with and I would highly recommend LA Basement Waterproofing."

"Dennis from Atlas just left my house a little bit ago. Couldn't have been nicer. I thought I had water coming up through the floor of my basement. It turned out to be a plumbing-related leak. He gave me a ton of good advice. Clearly a really honest and friendly guy. Even told me to give him a call if I had any questions or needed a second opinion on the plumbing. Really great. Would definitely call them again if the need arose."

"My husband and I had a wonderful experience with The Real Seal in July 2024. They fixed a bowing foundation and waterproofed the basement for future finishing. Their team was prompt, respectful, organized and thoroughly educated us on the drainage tile system, installation process and prevention. Thank you, Real Seal for being the flawless first step to our dream basement/family space!"

"I worked with Austin Werner at Real Seal to get some basement sump pump work done. He came out initially and gave me a quote and different options for my basement sump pump. He was very knowledgeable and gave pros and cons of different options. The quote was priced very fairly. They were able to get us on the schedule quickly. On the day off, the Real Seal technician called me the morning to let me know what time they would be here. The job was done very professionally and they answered all my questions. They cleaned up after the install. Highly recommended."

"I would like to thank Mariano and crew from Chicago Basement Systems for the very efficient work they performed in my home crawl space. They replaced my failed sump pump and drain tile; installed a Sani-Dry Sedona dehumidifier; installed a backup battery; installed steel beams and piers; installed a waterproofing membrane on the crawl space floor; and encapsulated the entire crawl space. Now I don't smell odors seeping from my crawl space, and my house no longer shakes when cars drive over the city speed bump outside my house. Also, I can now use my clean dry crawl space for extra storage. Thank you Chicago Basement Systems for peace of mind knowing that this project has a lifetime transferrable warranty. I highly recommend Chicago Basement Systems for crawl space repairs!"

"This was my first experience with J&S Plumbing, and I was very pleased. The outside discharge pipe from my basement sump pump had developed a leak and was flooding my yard. Despite the fact that the ground was saturated, they were able to dig down, find the leak, repair it, and then did a great job putting back all the mud and grass so that it is level. I will definitely call them the next time I need a plumber."
