San Mateo's Fast Answer to Plumbing Emergencies
When a pipe lets go in San Mateo, minutes matter — and so does being close. GB Plumbing dispatches from Carolan Ave, just north in neighboring Burlingame. When you call (415) 738-1450, we're not crossing the county to reach you. We're often at your door in 15-25 minutes, whether you're in Baywood at midnight or over in Shoreview on a holiday morning.
A real licensed plumber answers every emergency call — no answering service, no "we'll get back to you Monday." We dispatch immediately and arrive with a fully stocked truck ready to stop the damage and make the repair on the first trip.
"Our water heater let go and flooded the garage in Hayward Park on a Saturday night. I called GB expecting a machine, but a real plumber picked up and was at our place inside 20 minutes. He drained it, swapped the unit, and cleaned up after. Couldn't ask for better."

San Mateo Emergencies We Handle — Day or Night
Why San Mateo Homes See Sudden Emergencies
Aging Lines in Vintage Neighborhoods
Baywood, San Mateo Park, and Aragon are full of charming older homes — and many still run decades-old supply lines. Corrosion builds quietly inside those pipes until one gives way, often overnight.
Bayfront & Shoreview Flooding
Low-lying Shoreview and bayfront blocks sit close to the water table. Winter storms and rising groundwater overwhelm drains and sumps, sending water into garages and lower floors fast.
Mixed Old-and-New Plumbing
Remodeled San Mateo homes often join new fixtures to old rough-in plumbing. Those mismatched connections are weak points that fail under pressure when you least expect it.
While You Wait: How to Minimize Damage
We're on our way. Here's what you can do right now to reduce damage until we arrive:
Shut Off the Water
In most San Mateo homes the main shutoff is near the front where the meter is, or in the garage. Turn it clockwise until it stops. No water flowing means no more damage piling up.
Turn Off the Water Heater
With the water off at the main, switch your water heater to "pilot" (gas) or flip its breaker (electric) so it doesn't overheat while dry.
Move Valuables Up
Lift electronics, documents, and irreplaceable items above the water line. San Mateo's older hardwood floors soak quickly, so every minute counts.
Document for Insurance
Photograph the damage and the source before cleanup. We provide repair documentation to support your claim.
If It's Happening Right Now — Call, Don't Fill Out a Form
For active emergencies with water flowing, call immediately. The form is for non-urgent requests. Every minute matters when water is running.
