Plumbing Repair in Berkeley, CA
Most plumbing problems in Berkeley homes are repairs, not replacements: a leaking joint, a running toilet, a tired valve behind original tile. The goal is fixing the problem in front of you and telling you honestly whether anything bigger is coming.
Last reviewed October 15, 2026
Quick answer: For a leak, a running toilet, a dripping faucet or a slow fixture, a repair is usually the right first step, and many don’t need a permit. Gas lines, water heaters, repipes and sewer laterals do need a licensed plumber and a City of Berkeley permit. Call (510) 822-3070 to describe what’s happening; you’ll hear whether it’s a quick fix, a bigger job, or something a handyman could do.

Repair or replace?
The honest answer depends on the part and the pipe behind it. A good rule: repair when the problem is a worn part on a sound fixture or line; replace when the body is cracked, parts are gone, or the same repair keeps coming back.
- Several leaks on galvanized pipe? That’s usually a sign to plan for repiping.
- Drains that keep clogging? That’s often the sewer lateral; see drain cleaning.
- Water heater trouble? See water heater repair and replacement.
- Gas smell or gas work? See gas shut-off valves, and for a strong smell, leave and call PG&E.
Handyman or licensed plumber?
A handyman can swap a faucet, change a flapper or clear a trap. Gas, water heaters, sewer work, repipes and anything needing a permit belong with a licensed C-36 plumbing contractor. You can look up any California contractor’s license at cslb.ca.gov.
Checking for a hidden leak yourself
- Turn everything off. All taps, the dishwasher, washer, irrigation and ice maker.
- Find the EBMUD meter. Usually in a box near the sidewalk; lift the lid carefully.
- Watch the dial. If the low-flow indicator or sweep hand moves, water is leaking somewhere.
- Narrow it down. Shut the house valve: if the meter stops, the leak is inside; if it keeps moving, it’s between the meter and the house.
Questions about the meter or your bill go to EBMUD at 1-866-403-2683 (EBMUD contact). Leaks on your side of the meter are yours to fix.
FAQ
Common Questions
Should I hire a handyman or a licensed plumber?
A handyman is fine for swapping a faucet, replacing a toilet flapper or clearing a sink trap. Call a licensed plumber for gas lines, water heaters, sewer work, repipes and anything that needs a permit. If you call about something a handyman could handle, you’ll be told.
Do I need a permit for plumbing repairs in Berkeley?
Small repairs like clearing a clog, fixing a leak at a fitting or replacing a fixture usually don’t. Water heaters, repipes, gas lines, sewer laterals and remodel plumbing do. Permitted plumbing work on an existing building also brings in Berkeley’s seismic gas shut-off valve requirement.
How can I tell if I have a hidden leak?
Turn off every tap and water-using appliance, then look at your EBMUD water meter. If the dial or low-flow indicator is still moving, water is going somewhere. A sudden jump on your EBMUD bill with no change in habits is the other common clue.
Why does my toilet keep running?
Usually a worn flapper or a fill valve that’s out of adjustment. Both are inexpensive parts. A toilet that rocks, leaks at the base or smells is a different problem: the wax seal or the flange underneath, which should be fixed before it damages the floor.
Can old fixtures be repaired instead of replaced?
Often. Many older faucets, tub valves and toilets take standard or rebuildable parts. Repair is worth trying when the fixture matters to the house or the valve is buried in original tile; replacement makes sense when parts aren’t available or the body itself is cracked.
Is a pinhole leak a sign I need to repipe?
One pinhole leak can be a one-time repair. Several in a short span, especially on galvanized pipe, or on copper with green corrosion, suggest the system is wearing out. Fix the leak, then get the rest of the pipe looked at.
