Emergency Plumber in San Francisco
Same-Day Emergency Plumbing for Residential & Commercial Properties
Nigel Mulgrew Plumbing has served San Francisco and the Bay Area since 1998. Our team of 20 licensed plumbers responds to urgent plumbing calls across the city, handling everything from burst pipes in century-old Victorians to sewer backups in commercial buildings. We’re fully licensed, bonded, and insured in California, and same-day appointments are available when you can’t wait.
San Francisco’s building stock creates plumbing conditions you won’t find elsewhere. Galvanized pipes in Edwardian flats, aging sewer laterals, and seismic risk mean that when something fails, it can fail fast and hard. We know these systems because we’ve worked inside them for more than 25 years.
When a plumbing emergency can’t wait, call our team directly at (415) 857-9980. Same-day service is available for urgent plumbing needs throughout San Francisco.
Emergency Plumbing Situations We Handle in San Francisco
Our emergency plumbing services cover the full range of urgent situations SF property owners face. Each of these scenarios can escalate quickly, and getting a licensed team on-site fast can make a real difference in limiting damage.
- Burst & corroded pipe repair: Older galvanized and cast iron lines in San Francisco homes are prone to sudden failure, especially under seasonal pressure changes.
- Sewer backups: San Francisco’s combined sewer system carries both wastewater and stormwater in shared lines. During the rainy season, heavy flow can push debris into residential and commercial laterals and trigger backups.
- Gas line concerns: We provide gas line plumbing and can assess suspected leaks once the building has been cleared and PG&E has secured the line.
- Water heater failure: Sudden loss of hot water or a leaking tank is an emergency, particularly in multi-unit buildings. We repair and replace water heaters the same day.
- Drain emergencies & overflowing toilets: From a single overflowing toilet to a building-wide drain stoppage, we diagnose and clear the problem at its source.
- Leak detection & water line repair: Hidden leaks can cause structural damage fast. Our leak detection services locate the source before the damage spreads.
- Seismic shut-off valve installation: For properties that want earthquake preparedness built in, we install seismic shut-off valves that can automatically cut gas flow after a significant seismic event.
Why San Francisco Property Owners Call Nigel Mulgrew Plumbing
Speed matters in a plumbing emergency, but so does capability. A plumber who arrives quickly but has never worked inside a San Francisco property with pre-war piping, high-end European fixtures, or a complex sewer lateral isn’t the same resource as one who has. Our team brings both.
25-Plus Years in the Bay Area
We’ve worked San Francisco’s residential and commercial properties since 1998, building working relationships with homeowners, architects, and contractors across the city. That history means our team recognizes the plumbing configurations common to SF’s building types before we open a wall.
A Team Large Enough to Respond
With 20 licensed plumbers on staff, we don’t hit the availability bottleneck that smaller operations face. When urgent calls come in, we have the capacity to respond the same day without pulling someone off another job mid-project.
California Licensed, Bonded & Insured
Our licensing through the Contractors State License Board (CSLB), combined with our bonding and insurance, can protect you if anything goes wrong during a repair. That coverage matters in an emergency, when decisions are made quickly and stakes are high.
Experience in High-Value Properties
We work regularly with premium fixtures sourced from top European brands, with installation values ranging from $2,000 to $50,000. When an emergency involves high-end finishes or specialty fixtures, that familiarity means we can avoid causing additional damage while solving the original problem.
Responsive Communication & Eco-Conscious Methods
We prioritize clear communication from the first call through job completion. Our team also practices environmentally responsible plumbing methods, minimizing waste and disruption on every job. We serve clients in English and Spanish, and our diverse team brings a wide range of techniques to complex situations.

When an Emergency Strikes: What to Do Next
The first few minutes of a plumbing emergency can determine how much damage your property sustains. While you wait for our team to arrive, a few immediate steps can limit the impact.
Immediate Steps Before We Arrive
Take these actions as soon as it’s safe to do so:
- Burst pipe or major leak: Locate and shut off your main water supply valve to stop water flow to the building. In most San Francisco homes, this is near the water meter.
- Suspected gas leak: Leave the building immediately. Don’t switch lights or appliances on or off. Call PG&E to report the leak, then call us once the building is cleared.
- Sewer backup: Stop using all drains and toilets in the building. Continued use can worsen the backup before we can assess the line.
- Overflowing toilet: Shut off the water supply valve at the base of the toilet to stop the overflow at its source.
- Clear the path: Move anything blocking access to the affected area so our plumber can get to work immediately on arrival.
