MMT Waterproofing

Mario is the ultimate service person. He returns phone calls promptly, keeps you updated, answers all your questions, stands by his work, and helps you through issues, even the ones that are not his fault. After waterproofing the wall on the driveway side, a paving company I hired to redo my driveway carelessly ripped out some flushing and some membrane which the paving company refused to repair properly. Mario came out to fix the issue at no cost but we had to make do without the flushing. After the last torrential rain that lasted about 40 minutes, we found we had a leak in 2 areas of the basement on the same wall. Mario came out to do some water tests with hoses. We found that the problem was due to our wooden door sill which he had previously warned me about. He has recommended changing our door sill and when that is completed he will come to waterproof the external joint again at no cost. The other problem was at the corner of the driveway wall and the front wall. Because moisture seemed to come from 2 directions and he couldn't be sure that it wasn't coming from the driveway side, he offered to dig up a section of the wall he had waterproofed at no cost to me. As of this writing, he will come back and waterproof the front wall, revisit about 2 feet from the corner of the driveway side, and waterproof the joint of a new door sill. It has been stressful but Mario made sure that he was there for us.
