Mowery unclogged a very old, very stubborn clog…it was very tough, down a shared drain that was originally installed wrong. Persistence and experience removed the clog without having to cut into the ceiling or into the stack. Kevin L. was very knowledgeable, and professional. He worked really hard to clear the clog…it was a crazy old clog that was preexisting when we bought the house so who knows how old it was. I was shocked he was able to move it without really drastic measures. I’d call Mowery and Kevin L back any day for any plumbing issue that comes up for us in the future.
