Why Alamo Calls Us
We're not routing
from another city.
Our team operates out of our Concord shop on Medburn St., putting us just minutes from Alamo via I-680. When Alamo homeowners call, we dispatch promptly — no long waits, no runaround. You speak with our team directly and get a licensed plumber on-site fast.
Alamo's plumbing landscape is unique. From the sprawling ranch estates along Stone Valley Road and the equestrian properties near Livorna Road, to the luxury homes in the Round Hill Country Club area and the Alamo Creek corridor, every property has its own character. Large lots mean long sewer runs and complex irrigation tie-ins. Older ranch construction often has aging galvanized supply lines, while newer custom builds feature high-end fixtures, multi-zone systems, and tankless water heaters that demand expert care.
We handle the full range of residential and commercial plumbing needs in Alamo — from routine drain cleaning and water heater service to full repiping projects, sewer line replacements, and leak detection on complex systems. As an unincorporated community under Contra Costa County jurisdiction, Alamo has no city plumbing department — which makes choosing a licensed, bonded contractor like Guerra Bros. all the more important.
