      Worst experience with a Plumber ever.  Take a look at the dates of the positive, 5 star reviews, they're from years ago.  He has proven himself to be untrustworthy, dishonest, unreliable, etc etc.  We have had the inspector out several times and Spencer's work can not even pass inspection.  He blames the City, the Inspector, but not himself.  We foolishly paid him for work that needed to be redone, yet again, trusting that he would correct his mistakes and a month later he continues to fail to even show up to the Job Site and lastly this is a rebuild in Coffey Park and so Spencer knows he is holding up completion of a house for someone who has suffered enough already.  I would not recommend attempting to use his services.

      We called 3 plumbers and by the time one of them called us back, Spencer was already at our house getting the job done. We're in Marin, so I originally thought he would be the least likely to help us on a Friday afternoon. He was at our house within the hour and the valves were replaced and the area cleaned up within two. Spencer also tightened our sink faucet and fixed our garbage disposal. Now we can do laundry again!
