Long story short, our basement was continuously flooding. John and Andre quickly were able to reroute the sump pump drainage to prevent further flooding in our basement, and worked tirelessly to dig out our front yard and install a backflow valve. He helped with the paperwork necessary to get a rebate from the city, and was at our home the same day when a part of the installation malfunctioned (briefly). John and his son Andre are kind, honest, no-nonsense guys, who are polite and courteous and never feel like they're trying to give you the run-around. Their work is fast and efficientIt's no surprise they're so highly rated here. Can not recommend them highly enough.
