I used Guerriero Paving & Sealcoating to install driveway block and sealant. They didn't leave enough drains in the block and every time it rains, I now have a lake in my driveway. 3 weeks after the seal coating was applied, it started to peel off and a few months later, all of it was GONE. I immediately called Paul who told me he would take care of the problems. ONE YEAR later, they never came back to fix them. Dozens of calls were made to Paul without any response. DO NOT USE THIS CONTRACTOR.
