After doing considerable research ahead of time, I selected PEX-A pipe with ProPEX fittings. California Repipe Specialist's price was the most competitive of the three quotes I received. CRS even added some features the other two companies either did not offer or didn't explain they would be doing. The repipe crew (about six guys, I think) knew EXACTLY what to do and what each of their jobs was. Surprisingly they finished the job in ONE DAY. The drywall crew (one guy) came a few days later, which fit into my schedule and completed the drywall repairs in two days. I am very pleased with CRS and have already recommended my neighbor use them before her pipes begin to leak.
