Get matched with top concrete leveling pros in Zion, IL

"The work went extremely well. The concrete is now properly raised and sloped for drainage. The gap between the slab and my front stairs is also sealed. It looks great. I highly recommend Perma-Seal."

"These guys are amazing! They took a concrete pad, cut it in half and raised one section to create a step. This allowed for easy entry into our building instead of a high stair. Secondly, they leveled a 50 foot long span of sidewalk where each section tipped a different direction. It was a mess and they made it smooth and hazard free."

"Very well, our home is more leak proof / water tight than when we bought it some 30 years ago... and is anticipated to remain so for another 30+ years. All the mentioned work occurred during 3 visits spread across some 18 months; but none of the visits required more than a single day to complete. Work was conveniently scheduled and the worker(s) always arrived on time; if not 15 minutes early. A year after our last work was done (the poly-jacking), The Real Seal, at my request but at no charge, even sent out a technician to replace/redo some concrete plugs in those poly-jack holes that had popped out probably due to outdoor temperature swings."

"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."

"100% Professional Service! Arrived on time. Made quick work of the project. Appreciate the result. Would definitely hire for other concrete leveling projects in the future."

"I know of no other contractor who has total customer satisfaction as his top priority like Mr. Flanagan does. He is absolutely the best.
My basement sustained ankle-deep water as the result of an outdoor basement stairwell drain that violently backed up because its circa-1951 drain line led to the street storm sewer (by design). That sewer was overcome with water during a storm in the summer of 2010 that featured a tornado in my western-suburbs area. Soon after pumping the water out of my basement with a mobile pump, the mess prompted me to (once again*) call Mr. Flanagan (*His crawlspace crew had done a beautiful job finishing my dirt-floor crawlspace with a concrete floor and wall insulation a couple of years earlier).
After the basement waterproofing project described in this review was complete, however, I was disappointed with the workmanship: The concrete work looked less-than-professional (out-of-flush with sump flange and the stairwell drain, plus way too many swirl marks and splattering) in the stairwell and basement's appearance areas. In short, it just didn't look like his business's flawless concrete job that was done in my crawlspace just years earlier.
Mr. Flanagan agreed. With no questions asked, he immediately had a different crew come to my home, tear out all of the previously laid concrete and drain lines and replace it with the workmanship that he would expect his crews to use in their own homes. The re-do of the project at least had met my high expectations for its cosmetics. And, of course, I hoped it was a sufficient waterproofing solution for my basement.
Fast forward just a few short years. Affter having perhaps sustaining that 100-year event with the Chicago-area rain storm of April 17-18, 2012, while my neighbors are pumping water out of their basements, mine remains bone dry. Thank you Mr. Flanagan and Crawlspace / Basement Waterproofing Solutions for a job (design and installation) well done. Your basement waterproofing solution indeed deserves an A+.

"Jason and team did a great job.  Jason came out within a day or two from my initial email and we discussed all the options/services they provided (liner, concrete, crack repair, and spray foam insulation.  I really appreciated how he discussed the pros and cons of each solution and his low pressure style.
ABC Crawlspaces prices were the the lowest of all the bids I got and I was even told by other insulation companies if I could get closed cell insulation for that cost that I should go for it.  The best thing was their service and quality of work.  It is rare to find a company that has fair prices and good service, but ABC Crawlspaces is one of those companies.  We are very happy with all they did for us and our basement is much more usable and the air quality has improved dramatically.  Thank you Jason!"

"I only have good things to say about this company. I was contacted minutes after I requested a quote. The repairman came out the next day and gave me a quote. I also got a second quote from another company. I went with Concrete Correctors because their quote was slightly higher, however, they would take the job to completion which included restoring the drywall which is now ready for me to paint. The worker was clean and efficient. Additionally, he did a plumbing job for me for a good price and once again he did a great job. I will add this company to my Rolodex and recommend them to anyone who needs concrete work done."

"Crew arrived on time and worked efficiently. As the project progressed, 2 foundation cracks were discovered which added $900 to the original estimate. Old insulation along foundation wall was removed and replaced with silvery foam sheets. Joints were taped. Some leveling of the floor was done. Sheets were laid over the gravel floor also (crawlspace is not used for storage). 2 window well covers were installed. Our main goal was to have a warmer floor in the room above. We haven't noticed a major improvement yet."
