Customer reviews
Donald from ASAP Plumbing was super quick and responsive. Helped me out in both San Francisco and South San Francisco. On the first occasion, he was able to unclog the drain in no time! On the second occasion, he was able to push out the "thing" that was stuck in the pipes, saving me from having to potentially replace the toilet entirely!! Super professional and easy going. 100% recommend.

I worked with Don for a few years now. Over the years, he had helped me install a toilet, garbage disposal, and fix a few emergency nasty sewer drain clogs. He never fails to fit me into his schedule. Don is one of the most honest plumbers I have dealt with. Ask your questions and he will be more than happy to help. I switched a lot of different plumbers over the years but Don is definitely my first call now. Go with DDD Plumbing San Francisco Drain Cleaning!

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?!

Don was the man. I called him when my toilets had trouble flushing. Turned out it was a clog in my main sewer line. Scheduled a time with him same day. He showed up on time and quickly got to work.<br><br>It was a tough clog but he was in and out in about an hour. He cleaned up his mess and installed my toilet back. Very pleasant experience and will definitely reach out if I have future issues. Prices are very reasonable and he was very kind to provide a 30 day warranty as well! Go with Dr. Don!!

ASAP Plumbing Pro was called for replacing sewer line during our ongoing driveway and sidewalks project. Donald, Kong and Renato started working as early as 6am, in order not to delay the concrete and pavement. They finished the job before 9am, right before concrete men show up. They are definitely deserved the name of “ASAP”, and highly recommended!

Don was wrapping up a job in Redwood City and heading to San Francisco, so he offered to stop by my place (on the way) immediately and get things done. I like that.<br><br>He did a great job and got it done and confirmed everything was working and cleaned up before he left.<br><br>I honestly don’t know the going rate for such work, so I cannot comment on the “good value” button, but I was very satisfied. He was OK with being paid with cash. That’s slowly becoming a good business advantage.

Drain Doctor Don has cleared our sewer line of tree roots twice now, and we will continue to use him in the future until we have the line replaced. Great value and very reliable.

If you’re looking for a reliable plumber, Don should definitely be on speed dial! I’ve been using his services for 2 years. He’s fixed everything from clogged sinks to toilet clogs and also replaced my toilet and garbage disposal. I live in an older home in San Francisco and some of those drain clogs were extremely difficult to fix but nothing Don can’t handle. Give him a call!
