"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 needed the sill plate and rim joist replaced, sister in the joist in the front of our house. They had many jobs going on so they brought in a crew Anthony, Jerry and Jose from New Jersey so the could get mine done. Anthony let me know what they were doing as things progressed. He asked me if I had questions as he worked. Everyone in the crew where so considerate. The laid down tarps to walk on so as not to damage my floors and they cleaned up everything and the end of the day. I would recommend Chicago Basement Solutions to anyone who needs work done in their crawl of basement."

"It went great! Stan and his apprentice did an amazing job installing our high efficiency furnace and air conditioner. Stan was very informative during the entire process and even gave us ideas on how to do the basement when we finish it. I believe Stan went the extra mile and you can tell he loves his job. That's the type of service people you want working for you."
