Mike's company won the bid to replace the perimeter drainage around my home on the basis of experience, references, and cost. Mike and his partner did the work personally, on time and on budget. The excavation around my house proved to be much more difficult than expected (huge rocks, buried concrete, etc.), however, they worked hard, completed the project on time and did not ask for any additional money. Within days of completing the project the air in my basement was noticeably drier. Mike is very polite, easy going and maintains a tidy work area. He also took photos of the work while under construction, which is great for future reference. Their price was less than I had expected to pay based on three prior quotes. Highly recommended on the basis of cost, quality and management.
