I co-own a Victorian duplex with another woman. We needed to waterproof a corner of the basement and install a back flow valve and sump pump. We had three estimates and decided to go with Manny. He was not the cheapest but he had the most sensible and realistic explanations of the pros, cons and risks, all with a friendly no BS attitude. And no condescension. His crew arrived EXACTLY when they said would, and cleaned up thoroughly everyday. A basement window was replaced before we even realized it had been damaged in the excavation. He arranged for an HVAC guy to redirect duct work to accommodate the sump pump, and create a more open environment. All on time. During the recent summer storms, when we experienced leakage elsewhere, Manny returned our call immediately and came by the next day to inspect the main drain. I totally trust Manny and his team.
