"Real Seal are very professional. Came out when they said, sent estimate and set up to have work done in a timely matter. The technician sealed two cracks in our foundation crawl space. Did a excellent job and was very friendly and knowledgable. I will be using them again for another crack."

"I have hired Permaseal to fix my unleveled patio concrete floor that was and still causing rain water to get to my basement, I have paid them $2,014.33 as down payment, they showed up one month later for the job, which is injecting foam under the concrete slab to lift it back to its original correct level. I came back home that day to find out that they have left and that the concrete slab was not only still unleveled, but they cracked it and patched it on multiple locations. I have called their customer care number more than a dozen times in attempt to understand what is going on, and on each occasion, I was told that the project manager was going to contact me back, which never happened until i made the next call, They have finally explained to me over the phone that it was the best they could do and that they could not fix my patio floor. I asked for a refund and did not hear back. I have documented pictures of before and after showing that the job was not done and cancelled the check with the remaining balance. I have not heard anything back from them since then, until i started getting debt collectors' emails on December the 5th from a business called FCR Services."

"Hector and his team did d an outstanding job. My new driveway is beautiful. They showed up when promised and worked hard all day. They found a problem with the foundation of my house that needed to be repaired before replacing the driveway and rebuilt the foundation wall next to the driveway. I would recommend them to anyone needing concrete work done."

"Had a chimney cleaning and inspection in early Oct. Both Sol and his assistant Margaret were friendly and professional. Sol is very knowledgeable and answered all my questions, and I felt very comfortable with going ahead to have his company install a chimney liner. Greg and Gary came about 10 days later to do the installation, and were also friendly, professional and respectful of my home. They politely answered more questions and cleaned up the area better than it was before."

"This is the second home where Brookside has done window replacement for us and I cannot say enough about Eric and his team! Eric was an excellent communicator as we awaited the COVID influenced delay in the window delivery. His team does excellent work, pays much attention to the details and leaves everything so clean! We already notice the reduced noise and increased warmth in the house!"

FAQs for concrete foundation repair projects in Union, IL

Visible cracks, water leaks, uneven floors, or walls that won’t line up are classic red flags. You might also notice sticking windows, doors that no longer latch, or exterior cracks crawling up brick or siding. Even a damp, musty basement can hint at trouble. If you spot any of these, call a foundation pro right away. Early inspections cost far less than waiting until the damage threatens your home’s stability.

Yes, foundation problems impact your home’s value. Buyers want proof that the foundation is stable, and a recent, professional repair can actually boost confidence in your home. You’ll need to disclose the work, but documentation showing the structure was properly stabilized, especially with piers in regions known for shifting soil, often reads as a plus, not a problem. Skipping repairs, on the other hand, can cut your sale price and shrink the pool of interested buyers. Taking care of the issue protects both value and peace of mind.

Foundations are engineered for exceptional longevity when constructed correctly and maintained diligently. Concrete slab foundations remain structurally sound for 200 years, while other foundation types deliver integrity between 75 and 100 years. Regular professional inspections and timely maintenance further secure a foundation’s lifespan and ensure your home stays safe over the long term.
