About emergency plumbing
An emergency plumbing call is any situation where waiting will cause active damage, health risk, or loss of an essential home system. Burst supply lines, an overflowing toilet you can't stop with the local shutoff, sewer water surfacing through a floor drain, or an unheated home in the middle of winter all qualify.
The goal of the emergency visit is threefold: stop the immediate damage, restore basic function where possible, and set a clear path for the permanent repair. On-site, that usually means shutting off the correct isolation valve, drying and assessing the affected area, and either completing the fix or scheduling the return work with the right parts.
Common signs you need emergency plumbing
- Water is actively leaking and you can't stop it at a fixture valve
- Sewage or wastewater is backing up into a tub, shower, or floor drain
- There is no water at all coming into the house
- No hot water during cold weather or for a vulnerable household
- You smell natural gas or hear hissing near a gas appliance or line
- A pipe froze, thawed, and is now leaking
- A water heater tank is leaking from the bottom
- A toilet is overflowing and won't stop after shutting the supply valve
When should you call a plumber?
Call for emergency service the moment you see active water, smell gas, or lose an essential system (no water, no hot water in cold conditions). For a slow leak, a dripping faucet, or a slow drain that isn't backing up, next-day service is usually appropriate and less expensive.
If you smell gas, call PG&E or 911 before calling a plumber. Utility response comes first for gas safety. We handle the licensed repair after the site has been cleared.
What happens during a service visit?
When you call 408-205-1443, we ask a short set of questions to understand what's happening: where the water or smell is coming from, whether you've been able to shut off the local supply, and whether anyone is at risk. That helps us bring the right tools and give you an honest arrival window.
On arrival, we isolate the problem, stabilize it, and walk you through what caused it, what we can fix immediately, and what — if anything — needs to come back on a scheduled visit with additional parts. You get a clear price before we do the work.

Local context — San Jose & Santa Clara County
A large share of San Jose housing stock was built between the 1950s and 1980s. That means many homes still have original galvanized supply lines, older cast iron drains, and water heaters approaching or past their service life. Emergencies in that housing stock often reveal underlying wear — the leak that woke you up is frequently the first symptom of a system that's due for planned work.
We serve emergency calls in San Jose neighborhoods including Evergreen, Willow Glen, Almaden Valley, and Cambrian Park, along with Santa Clara, Campbell, Milpitas, and the surrounding South Bay.
Plumbing Terms Explained
- Shutoff valve
- The isolation valve that stops water flow to a specific fixture or to the entire house. Every homeowner should know where their main shutoff is.
- Water main
- The primary supply line bringing water from the meter into the house. Shutting off at the main stops water everywhere inside.
- Slab leak
- A leak in a supply or drain line running under a concrete slab foundation. Common in older San Jose homes and often first noticed as a warm spot on the floor or an unexplained water bill spike.
- Sewer backup
- Wastewater flowing backward into fixtures because the main drain line can't discharge to the city sewer. Frequently caused by tree roots, blockages, or collapsed sections in the lateral.

Don't attempt yourself

- Removing a leaking water heater by yourself if the tank is still under pressure
- Pouring chemical drain cleaner into a sewer that's already backing up
