Paul is the man! He is very knowledgeable, professional, friendly, and easy to work with.
He came to my house to install a sink, fix a leaky toilet, and re-seat another toilet. It turned out he didn't need to re-seat the toilet (just caulk a bit), and he lowered his price. My friend said this is the only time she ever heard of a plumber charging _lower_ than his quoted price.
He is also easy to reach. I called him today about installing water filters in my house, and he immediately picked up and took the time to explain my options to me over the phone.
Overall, very happy so far, and plan to keep working with Paul in the future.
