Fire protection services in Downey, California

What Downey callers usually need

Most calls we get from Downey are about fire extinguishers. A business needs units tagged before an inspection, a few are already empty and need refilling, or an old unit has to be either serviced or replaced. Private hydrants come next. Then sprinklers and fire alarms.

Recent Downey quotes for annual extinguisher service have run $15 to $40 per unit, with repairs priced on site once the technician sees the condition and the agent it needs. A new extinguisher bought through Hedrick was quoted at $85. Hydrant leaks are different. We charge a $250 fee to send a technician to inspect the hydrant and write the repair estimate.

• Extinguishers: fire extinguisher service, annual certification, refills, hydrostatic testing and employee extinguisher training.
• Sprinklers: fire sprinkler service, installation, restaurant sprinkler inspections and restaurant sprinkler repair.
• Hydrants: fire hydrant service, annual hydrant testing, maintenance, repair and new installations.
• Alarms: fire alarm service and fire alarm repair.

Fire system service in Downey

If you searched for fire system service, you probably have a sprinkler system, a fire alarm, a private hydrant, or all three, and an inspector asking for proof they work. We service each one.

Each system runs on its own calendar. Water-based systems follow NFPA 25, and California's Title 19 adds a 5-year sprinkler service and certification that only a State Fire Marshal licensed contractor may perform. Fire alarms get tested at least once a year under NFPA 72. Private hydrants on your property are flow tested and inspected every year. Keep every report on file.

On a visit, the technician walks the system, checks valves and gauges, runs whichever tests are due, and explains anything that failed before you decide on a repair. We also get calls for single repairs, like a missing brass part on an exterior OS&Y valve.

Downey Fire inspects your building

Downey has its own fire department, and its Fire Prevention Division handles business fire and life safety inspections. The same division plan-checks fire sprinkler and fire alarm systems, and its Plan Check Section works with the city's Building and Safety Division. That's the office to satisfy.

In January 2026 the city adopted the 2025 California Fire Code with local amendments. The fire marshal described those amendments as mostly organizational. If a plan or permit depends on the code edition, confirm it with the Fire Prevention Division before work starts. Ask before you build.

Who may do the work

In California, extinguisher and water-based system service must be done by a firm licensed by the State Fire Marshal. Our California work is done by Hedrick Fire Protection. Hedrick holds C-16 fire protection and C-10 electrical contractor licenses and is licensed by the State Fire Marshal under Title 19 for portable extinguisher service and for inspection, testing and maintenance of water-based fire protection systems.

Downey fire protection questions

Does a brand-new extinguisher still need to be certified?

Yes. The fire department requires it, so a new unit gets checked and tagged before it counts.

Can a store-bought extinguisher be certified?

Often, yes. The gauge has to show the word "recharge," and the unit can't have a plastic handle, or it usually can't be serviced.

My extinguisher is 10 years old and was never serviced. Service it or buy new?

Buy new. If it's a stored-pressure dry chemical unit, it has already missed its 6-year internal maintenance and the 12-year hydrostatic test is coming up, so we usually recommend replacing it.

Is the hydrant on our property our responsibility, or the city's?

A hydrant on the private fire service main inside your property line is usually yours to test and maintain under NFPA 24 and NFPA 25. A hydrant on the public sidewalk usually belongs to the water system. Downey runs its own water utility, so call the city to confirm.
