Plumbing, heating, cooling, water heaters and electrical under one roof since 1961 — The price we quote is the price you pay.
A few quick checks make a real difference when the ground shakes or the smoke rolls in. Tap any one to learn more — then ask us about it.
ShakeAlert is the USGS earthquake early-warning system for California — it can give you seconds of warning before the shaking reaches your home. Enable it in your phone's Emergency Alerts, or install the free MyShake app. On your end, Cabrillo makes sure the physical side is ready: a seismic gas-shutoff valve, a strapped water heater, and a main water shutoff you can actually find in the dark.
Ask about seismic gas safetyMany San Francisco homes built before 1960 still don't. An earthquake-actuated valve closes your gas line the moment the ground shakes hard enough — quietly helping prevent fires and leaks while you get everyone to safety.
Ask about gas-line safetyCalifornia requires water heaters to be braced to the wall studs so they can't topple, tear a gas or water line, or cut off your emergency water supply in a quake. Two code-compliant straps are a small, fast upgrade.
Explore water heater serviceSmoke particles slip through windows and ducts and linger long after the sky clears. A whole-home air purifier and sealed ductwork keep the air your family breathes healthy year-round.
Explore air purificationKnowing where it is — and keeping it easy to turn — is the difference between a quick stop and a burst-pipe flood after a quake or a sudden leak. We'll show you yours and make sure it still turns freely.
Explore leak protectionSan Francisco's older homes often hide galvanized and decades-old piping that fails with little warning. Knowing its condition turns a future emergency into a planned, on-your-terms upgrade.

Annual maintenance through the C.A.M.P. program keeps your systems tuned, catches small issues early, and preserves the manufacturer efficiencies you paid for.

Because every home and every project is unique, warranty coverage varies by equipment and service. Most extended warranties require annual maintenance through Cabrillo's C.A.M.P. program, and all qualifying work must be performed by Cabrillo.

(415) 843-2900See all FAQsAn automatic seismic gas shut-off valve installs on your gas line and stops the flow of gas the moment it senses strong shaking — no power, app, or person required. Because a ruptured gas line is one of the leading causes of house fires after a major quake, it adds a real layer of protection even when no one is home. Some San Francisco permits and property sales call for one, so the surest way to know what applies to your house is to have it checked.
Read the full guide on earthquake gas shut-off valves for SF homes.
Every home has a main water shut-off that stops all water to the house — and when a pipe bursts, finding and turning it is the fastest way to stop the damage. In SF and Peninsula homes it's usually where the supply line enters (front foundation wall, garage, or basement) or at the street in a covered meter box. Find it before you need it, label it, and make sure it actually turns: older gate valves often seize, so upgrading to a quarter-turn ball valve means you can stop a burst pipe in seconds.
See our guide on finding your main water shut-off.
A typical tank water heater lasts on the order of 8–12 years, and tankless units generally last longer. Sediment and corrosion are the biggest enemies, which is why an annual flush and a periodic anode-rod check matter. Watch for rusty or cloudy hot water, popping or rumbling sounds, water pooling around the base, or simply running out of hot water faster than before — planning the replacement before a leak forces it means no cold-shower emergency and time to weigh a more efficient unit.

Keep windows closed and run your system's fan so the air keeps circulating through the filter. Upgrade to the highest-MERV filter your equipment can safely handle (often MERV 13), and add a whole-home air purifier for the finer smoke particles a standard filter misses. We'll tell you the best-rated filter your specific system supports without choking off airflow.
