Red flag
2 Yelp reviews document surprise fees or upsells beyond agreed scope (Rb7xhDohXoJRnhijPx5A, 8jXyFA7kxEe9RwJdwGq2) and 1 alleges billing for unnecessary work at inflated prices not to code (RASdIh1bn8gQ8ECbilh4).
“We were happy with them initially -- specially our first big project -- the installation of a tankless water heater which cost us about $4200. Thereafter, on a couple of occasions, we had some minor concerns with their work but we decided to overlook it.”

“This is a crooked operation. They work with property managers to inflate the estimate by doing work which is not necessary: water heater leaking in dual water heater system. They wanted to replace both of them instead of replacing the leaking WH. Their price was 30% higher than market for replacement of 1 heater and it wasn't done to code.”

The evidence — in reviewers' own words
Critical
“I needed a new sewer system because roots were growing into my sewer. Pierre gave me the middle price out of three bids. There was something I didn't like about the lowest bid, so I went with Pierre. They did a trenchless sewer replacement, but there were two minor problems and one HUGE problem. A year after the job, my plumbing backed up and a different plumber said I had roots in my sewer. I asked how this was …”
“We have used West Coast Plumbing over the last few years on several occasions. We were happy with them initially -- specially our first big project -- the installation of a tankless water heater which cost us about $4200. Thereafter, on a couple of occasions, we had some minor concerns with their work but we decided to overlook it. Recently our sewage was backing up into the bathroom shower. Westcoast sent Zezo …”
“Do NOT use this company, even if you had good experiences with them before! I've used WestCoast Plumbing a few times over the last few years. One major project (replacing the main pipe going into the house) and other small ones (unclogging the main pipe going out of the house). The owner, Pierre, came over the first time (major project) and second time (unclogging the pipe). We were very happy with the service …”

“We had a sink practically falling off the wall. The water was off in the house. Called West Coast Plumbing, Frank was the plumber.
