"Called at 7am about a burst pipe under the kitchen sink — they were here by 8:30. Fixed it completely, explained exactly what happened, and the price was fair. Couldn't have asked for more."
"Used Coast Plumbing for our water heater replacement and AC tune-up. Same crew, same company, no hassle. They've been our go-to for 8 years and they've never once disappointed us."
"I've had plumbers try to upsell me on things I didn't need. Coast gave me a straight answer, fixed the actual problem, and charged exactly what they quoted. I refer them to everyone I know."
