Why It’s on home.renovation.reviews
Concrete and waterproofing are among the least glamorous but most consequential renovation categories — poor drainage or a failed foundation seal creates remediation costs that dwarf the original prevention price. PMD’s St. Thomas Chamber membership, 30-review track record, and specialty depth in drainage and waterproofing make them a reliable directory entry for homeowners dealing with moisture, foundation, or concrete challenges.
