We had water coming up from the drain in the basement that connects to the kitchen sink and the laundry basin. Sergio went out to rent a snake to clear it but didn't tell me this, that he doesn't own the equipment. He sealed the opening around the drain with a bit of cement and said the problem was solved. For this he charged me $385. The water continued to come up through the cement around the drain. He didn't keep his word, never came back to fix the problem.
