Why Danville Calls Us

We're not routing
from another city.

Our Concord shop on Medburn St. is a straight shot down I-680 to Danville — no routing through dispatch centers or relay calls. When you call us, you reach our crew directly, and we schedule with Danville jobs in mind.

Danville's plumbing landscape is varied. The historic downtown corridor around Hartz Avenue features older homes with original copper or galvanized systems. Sycamore Valley Road and Green Valley neighborhoods mix 1960s–70s ranch homes with remodeled interiors. Blackhawk is a different world entirely — high-end gated estates with complex multi-bathroom layouts, recirculating hot water systems, and custom fixtures that require careful handling. Diablo Road properties often sit on large lots with long sewer runs and private irrigation. We know what to expect when we arrive.

Whether you're managing a single-family home off Diablo Road, a rental property near downtown, or a commercial space in the Danville business district, we handle the full scope — water heater replacement, drain cleaning, sewer repair, repiping, leak detection, and emergency calls — all under one CA license.

Had a slab leak under our Danville home and was dreading the process. Guerra Bros. came out, located it quickly, and explained every step before starting. Fair price, clean work, no surprises.

Water heater went out on a Monday morning. Called Guerra Bros. and they had someone at my Danville house by early afternoon. New unit installed same day. Great crew, very professional.

We have an older home off Green Valley Road with some serious drain issues. Guerra Bros. hydro-jetted the main line and had everything flowing again. They knew exactly what to do.
