"Juan came to the house and installed a new gas valve controller for my RHEEM water heater. He honored his over the phone price quote, and did a great job. He even checked my water pressure. No run-around here, just the honest truth from True-Blue Plumbing."

"First Thought Plumbing's Kenny is very professional, punctual, knowledgeable, pleasant and offers affordable and reasonable rates for his great service. I searched for a plumber yesterday and he was the first to call and respond to my need. He came on time, he knows what to do, very responsive to inquires via phone or text. Amazing, professional worker who won't price gouge or try to upsell you. Recommendable! Thanks Kenny!"
