What we do

Plumbing done by people who answer the phone.

Residential and light-commercial work across Alameda County. No call centers, no surprise line items. Just the crew that shows up.

Drain & sewer clearing

Slow sinks, backed-up mains, root intrusion. Camera inspection and hydro-jetting when it's needed, snaking when it's not.

Water heaters

Repair, replacement, and tankless upgrades. Same-day install on most standard tanks so you're not cold overnight.

Repipes & upgrades

Whole-home copper or PEX repipes for old galvanized lines. Clean routing, patched walls, permitted and inspected.

Leak detection

Hidden slab and wall leaks found with acoustic and thermal tools, pinpointed before we open anything up.

24/7 emergency

Burst pipe or flooding at 2am? A licensed plumber picks up, day or night, weekends and holidays included.

Fixtures & faucets

Toilets, faucets, garbage disposals, and shut-off valves swapped clean. The small jobs done without the runaround.

Our story

A local crew, not a franchise.

Harbor Plumbing started in 2011 out of a single truck. Fifteen years later we're still family-owned, still based in Alameda, and still the ones on your doorstep, not a subcontractor we've never met.

Every job gets the same deal: a plumber who explains the fix in plain English, a written price before the wrench comes out, and a clean worksite when we leave.
