“Guerra Bros. came out same day and fixed our water heater leak quickly. Honest pricing and professional service. They're based right here in Concord and it shows — faster response than anyone else we've tried.”
“I highly recommend Guerra plumbing. Tony was professional, knowledgeable and solved all of the plumbing issues. He explained the causes of the problems and offered suggestions for prevention.”
“Another plumbing company quoted $350 labor & $150+ for parts. Guerra Bros came out within 30 mins, fixed it under an hour for $237. Now I have hot water again. Local company, local prices.”
