Get matched with top concrete leveling pros in Chicago, 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."

"J & F did a great job. Julio was responsive, showed up on time and did a great job. They weren't able to shift over an extremely large piece of concrete that was out of alignment, but they did improve it, and we can landscape around the imperfection. We did have an estimate from another company that was a couple hundred dollars cheaper, but they never showed or contacted us back. So, there you go. Would hire J & F again."

"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."

"It went pretty well. They tool longer than I thought, and they used a sealant (gray) that didn't match the color of our house (white) or the concrete stoop. We were planning on painting it anyway, so in the end it's not a big deal. We like Real Seal and would use them again."

"I hired Konkretto to replace my old parking slab, and these guys completely surpassed my expectations. Not only did they make the parking bigger, they added their own creativity to it with the picture frame finish. Aside from being perfectionists and being high on detail, they are quick! They did the whole tear down and install of the new concrete in 1 whole day! They are amazing! Definitely reccommend them"

"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."

"The DNB team was very quick and thorough. They managed to lift our concrete steps over 5", when many other companies only promised 4". Definitely recommended."

"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+.
