Dave Bischof Plumbing

This man is a con artist masquerading as a plumber. We made the mistake of hiring him after finding him through a Google search to fix a broken pipe under our kitchen that was leaking into the crawl space under our house. He told us that we needed "remediation" to clean it out and that would come with a $6000 price tag. We signed a strange contract that he presented (with provisions like recording every conversation), and before we'd even given him permission to start, he punched a hole in our wall. When we told him to stop, he (recording all the time) told us that we were in breach of contract and slapped a mechanic's lien on our house (which, thanks to this experience, we learned is faaaaaaaar to easy to do). We spent $3000 to have it removed, which was still better than paying him a red cent. Don't let this devil into your house.

I was at work when my wife called with the blocked toilet story.  We picked Mr. Bischof from a phone book.  We ended up paying seven thousand dollars because he told my wife that the job would cost one thousand dollars and if he did this, there was a ninety percent chance that it would probably fix the problem.  When that didn't work for more thousands he could try this and it was a nine-five percent chance that the problem would be fixed, when that didn't work for more thousand he could try something else and there was a ninety nine percent chance that the problem would be fixed.  After already investing thousands we had to invest more to fix the problem rather than having already paid him thousands of dollars to send him home without the problem being fixed.  Then if we wanted him to use the  best router, the diamond router, it was another thousand.  The total cost of the job was seven thousand dollars.  I'm reporting it now because my mother in law had the same problem recently and it cost her near one thousand dollars.
Twice during the job, he told me I misremembered things.  I know I didn't because I was going to ask him a question about something he said, but I didn't ask it.  When he told me I misremembered what he said, I thought of the question I was going to ask him about what he said.
Do you believe that?   Seven thousand dollars for a blocked toilet.  I often wondered if things would have been different if I was home instead of my wife.

The traps needed replacing but couldn't be unscrewed from the pipe inside the wall. Holes were knocked in the wall and short portions of the pipes were replaced. Bischof had spent a few extra days looking for his drain-pipe unscrewing tool (like a giant pipe wrench), which couldn't be done. He took about 4-5 hours overall and charged me over $900 per replacement. We hadn't negotiated price previously, as the previous house occupant had used his services for many years and was very pleased with him, so I continued using his service on one job several years ago, which had seemed overpriced. This time, the parts didn't appear to be worth many hundreds of dollars, so it seems to me that he charged me about $400/hour for labor, which seems like gouging to me. He didn't clear the drain clog which had started the problem, and he left a leaky trap, which I called Michelangelo's Plumbing to fix. They were far more reasonable in their pricing.
