We hired Mario to waterproof our basement and two coldrooms. He was extremely professional and gave me a very thorough understanding of what our job would entail and what our options were. He even thought outside the box to help us get the waterproofing we needed without needing to tear up our basement floor. The work was done very quickly, and we've now had three storms with no water leakage. The work was excellent and I wouldn't hesitate to hire MMT again.
