Why Martinez Calls Us
We're not routing
from another city.
Our shop is located at 100 Medburn St. in Concord — just a short drive from Martinez via Highway 4. That proximity means we can dispatch quickly when a water heater fails or a drain backs up, keeping your wait time short and your disruption minimal.
Martinez has a uniquely diverse housing stock. The historic downtown is lined with Victorian and craftsman homes whose original galvanized supply lines are decades past their service life. The Vine Hill area and Alhambra Valley Road corridor bring a mix of mid-century residential and agricultural properties, each with its own plumbing character. The waterfront district near the Carquinez Strait includes older industrial and commercial buildings that require commercial-grade plumbing expertise.
From single-family homes in need of repiping to commercial properties along the waterfront, Guerra Bros. Plumbing handles both residential and commercial work across all of Martinez. We show up licensed, fully insured, and ready to give you a straight quote before any work begins.

Customer Reviews
Don't take our
word for it.
“Had a major leak under the kitchen sink in our old downtown Martinez Victorian. Guerra Bros. came out the same day, diagnosed the corroded galvanized line, and had it repaired before dinner. Really impressed.”
“Called them for a backed-up drain in our Vine Hill home. Technician was professional, explained exactly what was going on, and cleared the line quickly. Reasonable price too.”
“Our water heater finally gave out — I called Guerra Bros. and they had us back with hot water the same afternoon. Great family-owned company, highly recommend them for anyone in Martinez.”
