Why Lafayette Calls Us
We're not routing
from another city.
From our Concord shop on Medburn St, we keep Lafayette well within our service radius. That central location means we can roll a fully stocked truck to your door quickly — whether you're dealing with a morning emergency before work or need a scheduled service call that fits your busy day.
We know Lafayette's neighborhoods inside and out. The ranch-style homes along Happy Valley Road and Burton Valley frequently have the original 1950s-70s copper or galvanized supply lines that are nearing the end of their service life. The hillside estates off Reliez Valley Road present their own drain and pressure challenges, while Downtown's boutique commercial corridor on Mt. Diablo Blvd keeps us busy with grease-trap cleanouts and aging commercial fixtures. BART-corridor condos and mixed-use buildings round out the mix.
Whether you own a single-family home in Burton Valley, manage a multi-unit property near the BART station, or operate a commercial space Downtown, Guerra Bros. Plumbing handles it all. We are licensed, insured, and family-owned — the kind of contractor Lafayette residents trust to do the job right the first time.

word for it.
“Had a water heater fail on a cold morning in Lafayette. Guerra Bros. came out the same day, replaced the unit, and hauled off the old one. Excellent service from start to finish.”
“Our drain in the Burton Valley house was completely backed up. The technician from Guerra Bros. cleared it quickly and even ran a camera to show us what caused the clog. Very professional.”
