DO NOT HIRE THIS COMPANY. We had a stamped concrete patio done by General Concrete Services. They finished in one day. They returned the next morning to seal the concrete. While the slab appeared dry, and hardened, there is still a lot of moisture in the concrete. It appears the oil-based sealer displaced the moisture and created an appearance of water spots. (I have since been told it should have been allowed to dry for a few days to a week). Also, probably because there was no ground preparation done, there are two low spots where standing water puddles, one being right outside the main sliding glass door exit to the backyard. After it rains, we must let our dogs in and out through a puddle of standing water. Also, again because of lack of ground prep, they cut a relief line across the slab to "keep it from cracking" they said. You can see where the saw blade ran off the line and was re-cut. It looks terrible. Roberto Cazan initially said he could fix the sealer spots, but never set up a time to do it. After that initial conversation he refuses to address our concerns and will not answer his phone. read more
