Alex from 4 Star Plumbing Services came to our condo to replace an old shut off valve and clean up the copper piping that had started to corrode. He showed up on time, was friendly, gave us a cost estimate, explained what he was going to do and why, did exactly what he said he was going to do, tested the new valve and water connections for leaks, and cleaned up afterward. EXCELLENT! 4 Star Plumbing gets a 5-STAR Rating from us!!
