Get matched with top basement drainage channels installers in San Mateo, CA

"Short version:
They got the job done, but it took two visits and cost about 2-3 times more than it should have because they initially arrived with the wrong equipment and then recommended an unnecessary, expensive video scan.  The extra cost was due to their error and they should have covered at least some of it (if not all) but they refused.

Details:

Our sewer line backed up between our house and the street, and so I called In and Out to clear it.  They arrived with nothing but a hand snake because supposedly other equipment was in the shop.  The plumber was able to (temporarily) clear the obstruction with the hand snake.  Charge: $250, which also included cleaning the trap in one of our interior sinks.  So far so good (although if I'd known they'd come with just a hand snake, I would have done it myself...)
Two weeks later, the line backs up again, because the hand snake only punched a small hole in the obstruction rather clear it completely.  I called In and Out to come back with the correct equipment.  

This time they arrived with the proper equipment, including the full sized snake and water jet to clear the roots.  Given the previous failure to remove the blockage, they recommended sending the video camera down the pipes to diagnose the problem.  Problem = roots from the trees near the sewer line (surprise!).  They used the snake + water jet to remove the roots and clear the obstruction.  Now everything works.  Bill = another $775.  

 Why do they get a C grade?
Issue 1: they refused to refund any of the money from their first, failed intervention.  If they'd just arrived with the right equipment, we would have removed the roots on day one, sparing us another sewer back up and another expensive visit.  They brought the wrong equipment and didn't solve the problem -- there should be at least a partial refund.  Even an apology would have been nice.  But I didn't get either.   instead, we come to Issue 2

 Issue 2:  when they came back, they recommended an unnecessary (and very expensive) video scan of our system which just turned up the obvious problem of roots from the nearby tree.
Total cost was over $1000, for a job where most plumbers would have just gone in with the big snake + jet on day one and knocked out the roots for $250-400.   In and Out ultimately fixed the problem, but we had to endure 2 days of sewer back up and paid 2-3x what we should have.

On the plus side, they were always very prompt, professional, and friendly in person (aside from issues noted above)"

"Ariana cleared the pipes so bathrooms had proper pipe drainage. Ariana did an excellent job."

"After lining up three plumbing contractors to install a kitchen faucet, a garbage disposal and fix a drainage leak, I selected Superior Plumbing to do the job because their technician seemed to have the necessary professionalism for a good job and they were also the least expensive of the three contractors I contacted. My service tech Armin was on time, cheerful, courteous and knowledgeable. It was obvious that he cared for my particular needs and he even announced that he loves his job and always looks forward to doing things right. He took almost exactly the time that was originally quoted and did an excellent job, cleaning up thoroughly before leaving. I wouldn't hesitate to use their services again. Thanks Armin."

"I would give them six stars if I could. The entire process was smooth and pleasant. Fair negotiation, good price, excellent execution. We had to replace sewer lateral - a major work - and Faren and his guys did everything highly professionally and on time, including taking care of city permits, inspections, and protection of the site. Warmly recommended to everyone."

"Never in 20 years, living in this house, have I ever had a plumber travel from Monterey, CA, to do plumbing work on a house in Gonzales, CA. I was amazed that any plumber would come to Gonzales, CA, after 20 years of repeated negative experiences. Repaired the kitchen sink faucet. Replaced two (2) outdoor faucets. Recycled the water conditioner. Serviced the heating furnace. All work completed in a most excellent fashion. The plumber was very pleasant to work with. He was terrific."
