Shower valve and cartridge repair

I've worked with Donald of ASAP Plumbing several times over the past 4 years and can confidently recommend their services. He's unclogged drains, replaced kitchen sink water valves and garbage disposal, and resolved an active leak in my old rental apartment kitchen. He's prompt to respond to inquiries, shows up during the expected time window, and overall is a very friendly and personable guy.

My shower clogged last night and I was able to reach someone late at night and book a morning appointment! They were able to diagnose and clear out the clog quickly. I'll definitely be calling them for all future plumbing needs. Thank you!

I had a clogged toilet and shower in a lower floor bathroom. Searched on Nextdoor for suggestions. Saw excellent reviews for ASAP. Clicked on the site and received an immediate response. They were able to send someone within a couple of hours. Donald arrived to evaluate the situation. He was professional, knowledgeable, and friendly. He presented me with options based on his thorough examination of sewer pipes. We agreed on the less expensive option and it worked. He did an excellent job clearing the sewer pipe, and cleaning up afterwards. I will call them again for all plumbing needs and don’t hesitate to recommend their services to others.

Don dropped in on very short notice to replace several shutoff valves in one of my bathrooms as part of a larger time-sensitive project in the home. He was friendly, knowledgeable and professional, and helped me understand the root cause of the problem I was dealing with. I would highly recommend Drain Doctor Don to anyone with a plumbing issue!

I’ve been using Don since his business began. Don always offers the best prices for all San Francisco draining needs. I’ve used him for faucet installations, garbage disposal, drain clogs, outdoor and indoor plumbing needs, plumbing leaks, sewer cleaning, among other services for my properties. My neighbors also raved about his coverage in the San Francisco bay area region for shower installation, water tank needs, drain cleaning, sink draining, etc.<br><br>He far and away exceeds my expectations especially in the San Francisco Bay Area region where prices are exorbitant. With Don, you get bang for your buck for professional plumbing and drainage needs with free warranty for the first month! I’ll be using Don for years to come! Hey Don, time to start a loyalty program?!
