Great job highly recommend

Hey Leon, thank you for being such a great plumber and coming out to our office building and handling the smell that was going through the hallways! We had several tenants complaining about a smell of sewage in our office building and we’ve had two plumbers come out and could not figure it out. Leon With By The Book Plumbing came and he literally just poured some water in a floor drain and the smell stopped. It was a five minute repair for him where other people were trying to charge us like three grand to open up walls and see what they could find. He didn’t even charge us! So I’m writing this review. If you’re looking for an honest Plumbing Company By The Book is the one
