Eventually, he looked at the first project, 9 steps that needed some cracks repaired. Said they dont repair anything, only level. I had 4 jobs total, 2 sidewalks to level and a patio pad. We never got to other jobs, he was so rude and disinterested, that I asked him to leave.

Totally respectable workers and employees from start to finish! I feel like I got a new driveway for the fraction of the price of removing the old concrete and pouring new slab's. They used a pressurized slurry of limestone injected through the concrete to level the slabs across my entire driveway. The diamond ground all of the joints between my house and the driveway and between all of the slabs and sealed it perfectly! The before and after is incredible. Thrilled with the work and will recommend them to anyone who needs to have concrete leveling done!

The workmen showed up about 7:30 on the first and they immediately went to work. Every employee seemed to know what to do without any fanfare. Matt the person who was in charge of the project really impressed me with his work ethic. He fixed my cellar door so that it would open and close easily. It was an unexpected surprise. It took a little over two and a half days to complete the project that was supposed to take two days but they ran into a unexpected problem. They finished the job and left my place as clean as possible.

G&J put a French drain in my home less than two years ago. First off the workmanship was shoddy…read more The interior discharge pipe is just hanging out of the wall with the cement patch job on the interior side of the hole going to the outside being the only thing holding it in place. The cement patch work, interior and exterior, looks like it was done by a two year old. The "kids" who actually did the work were a couple of non-English speakers and someone who looked to be younger than my grandson. Less than two years later there are large cracks in the exterior discharge pipe. This causes the water that collects in the sump pit to just swirl around and go nowhere. This happens to coincide with a period of recurring rain, often heavy, over the past week. Of course the problem happened over the weekend. I emailed them about the problem on Sunday. To their credit, they did reply to the email. On Tuesday they emailed that someone would come between 10-2 PM the forthcoming Friday. In the meantime my wife and I spent the week (including in the middle of the night) bailing water out of the sump pit. Friday comes and I have to take the day off from work to be here when they come. But guess what? Nobody from G&J showed up and nobody from G&J even called. Instead they emailed me at 1:30 in the afternoon to say that most of their crews had called off because of a big storm the previous night (storm???). I blame myself for hiring these people in the first place. Don't make the same mistake. Stay away from G&J Waterproofing.
