Trademark Plumbing and Mark Billings are the best! Knowledgeable and friendly, he analyzes any plumbing problem, comes up with a solution, and completes the work quickly, cleaning, and thoroughly. Couldn't ask for better plumbing service.

Knowledgeable, responsive, courteous, excellent service!

Excellent job done on 65 year old plumbing in shower without damaging original tile. Also found us a replacement faucet with a single handle for our kitchen sink with faucet attached to the wall above the sink. Local stores do not carry such a faucet.

We appreciate the honest, fast and high-quality work, Mark!

Mark is great. Personable and professional. Not only is he able to fix tricky plumbing issues, but he fully explains his repairs. And he gives pointers on how to maintain repairs. He told us to use enzyme drain cleaner in out kitchen sink, which we'd never used.
