"We were getting some water in our basement, which The Real Seal determined was coming from a crack in the foundation. They identified and repaired the crack quickly. Our technician worked neatly and efficiently, and all staff were pleasant and responsive throughout the process."

"The workers did a great job leveling my steps. I didn't know the quote did not include sealing the material used to lift my porch. I called the company and they sent someone out to apply concrete over the exposed space."

"We have a 1920s bungalow with a cinderblock foundation and routine seepage issues.  Interior drain tile was also an option but with a partially finished basement, I think ultimately would have been more expensive after putting walls back together, etc..  And, personally i'd rather stop the water before it enters the house.  I felt as though i was getting the "cookie cutter" solution from the other highly rated angies list waterproofers and they definitely like to nickel and dime on their expensive battery backup systems.  Chuck spent a considerable more time at the house, didn't give us the BS sales presentation with all of the pamphlets, gave us a timely quote, and ultimately just made us feel the most comfortable.  
The job went very well and I wouldn't hesitate to use High Tech for additional jobs in the future.  Chuck is very professional and responsive, easy to work with.  It took a while to coordinate with the excavator which is subbed out, but we were in no big rush and everything worked out great.  The job took four days.  We've had some heavy fall rains and not a drop of water in the basement.

"When we bought this house we were planning to renovate the basement.  The previous owner had represented that it had never taken on water.  The first weekend we were here, however, a torrential rainstorm caused the basement to flood.  We realized we needed to waterproof it before we could do anything else, and decided that drain tiling was the safest way to go.
Greg was phenomenally responsive from the start.  He was very clear about what needed to be done and how they would do it.  He also described some optional work but was explicit that it was optional and if it didn't fit within our budget that was that, and he wasn't going to push it the slightest bit.  His quote blew away the bigger, well-known firm and was less than or on a par with some others.  He also agreed to demo the walls for a slight extra charge, which otherwise would have been a huge convenience for us.  Between then and the start of work I emailed him repeatedly with various questions and he responded almost instantly.  When his workers took down the paneling we got the unpleasant news that we had huge cracks in the walls that would need to be tuckpointed and in one area a big chunk of foundation was jutting from the wall.  That section of the foundation would need to be replaced and a support beam installed.  We were more or less at Greg's mercy at this point -- we weren't going to halt work and bring in a series of guys to quote the tuckpointing & repair -- but Greg gave us an estimate of $2,600-$3,000.  We can't know for sure, but suspect that this price was more than fair, and Greg stuck to it even though we think the work turned out to be more than they expected.
The project manager, Jim, was fantastic to work with throughout, very communicative and accomodating, and the crew of five guys or so was extremely friendly and professional.  All in all, A Perfect Crawlspace was a pleasure to work with and we could not be happier with the results.

"Brian arrived with his worker, assessed the issues and presented a couple of options to work with. The work was done efficiently in a few hours and I no longer have any leaks in my basement. I was very impressed with the work and the way he goes about his business. There was only one area that we could not figure out if it was leaking from the foundation or if it was coming from above. We agreed to test it the next rain fall and have him come back to fix that section. Unfortunately it didn't rain again until spring and when it did I was unable to reach him. I think this company is no longer in business or at least that is the impression I get because all of his contact information is no longer in service. It's too bad because I really like the work he did for the price he quoted.

"Dominick was timely with his appointment to provide an estimate. His estimate was accurate, and they kept to their timeline. Their office staff was incredibly professional and courteous. The crew arrived, prepped the work area with plastic where appropriate, and within 20 minutes were jackhammering the existing concrete. They didn't waste any time! The crew was courteous and professional. They hauled away all the debris as promised, making sure to keep the driveway clean of material. They laid down plastic outside in their staging area for concrete - a nice touch to keep the driveway clean. They cleaned up after themselves thoroughly in the basement, walked me through their finished project, and were just generally a nice group of guys who got the job done quickly, efficiently and on budget. They even patched a few holes outside of the original scope of work. Can't ask for more than that."

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.
