"There were about 6 things and altogether it added up to about $800. Since then I haven't called him back. I would give him an "A" for the estimate. It's just that the most important item on there, he said I didn't need it, because it was a matter of turning the shower off, I mean the diverter off. That is not the case, I tested it several times and it does need something, I don't know what. Since I had gotten the tub refinished I didn't want to have water dripping in it. I can't seem to find a plumber that wants to do that particular small job. He's one of a couple that I asked and they all said, all you have to do is turn it a certain way, but that is not the case. I have sort of put it on hold. I liked them. I liked him and the assistant, Brendon Nagle and his assistant. They are very nice and I felt they could do most things. I have to call the guy that refinished the tub, because he suggested I get this part and no other plumber seems to agree; but I know it's the case. I do not want to ruin the tub. It causes rust around the drain, the water sitting. It's complicated. I would call Brendon Nagle again, but I have to research this particular project. I thought the price was fair, but it didn't seem like a bargain to me. Even though the quality is not applicable, I would give an "A" for knowing and being jolly. They were there the next day."

"After dealing with roto rooter and Losch plumbing with very bad experiences. Thank God for finding Once & Done. Very professional crew, they did a great job in installing the new sump pump that we definitely needed. Jeff was very honest and nice and explained everything that had to be done in detail. Highly recommend."
