Dave and his team specialize in waterproofing, so they really knew what they were doing, and they worked quickly. They finished our job (exterior waterproofing on 1/2 of a large century house) in less than 3 days. They're familiar with different types of foundations, from century-old rubble or stone block foundations to newer poured concrete foundations. They also know the soils and subsoil types across the greater Hamilton area. Dave's quote was competitive, and his team did a great job, were pleasant, helpful and professional.
