How often do fire extinguishers need to be inspected in Houston?

NFPA 10 calls for a visual inspection about every 30 days, which staff can do, and maintenance by a licensed technician at least once a year. Some types also need internal maintenance every 5 or 6 years and hydrostatic testing every 5 or 12 years. Confirm current requirements with the Houston Fire Marshal's Office and your insurer.

How much does a fire extinguisher inspection cost in Houston?

As a rough estimate, annual inspection and tagging often runs about $8–$25 per unit, plus any trip or minimum service fee. Recharges, 6-year maintenance, and hydrostatic tests cost extra. Get a written quote. These are not verified Houston prices.

What's the difference between an inspection and a recharge?

An inspection checks that the extinguisher is ready to use and properly tagged. A recharge refills the agent and repressurizes it, and you need one after any use or when pressure is low. A hydrostatic test pressure-tests the cylinder itself every 5 or 12 years.

Can I refill a fire extinguisher myself?

No. Recharging requires certified equipment and agents. A DIY refill is unsafe and won't produce a valid service tag.

Do restaurants in Houston need special extinguishers?

Commercial kitchens usually need a Class K extinguisher near cooking appliances, in addition to ABC units elsewhere. The hood suppression system is inspected separately. Confirm with your fire inspector and insurer.

Fire Extinguisher Inspection, Recharge & Refill in Houston, TX

Updated 2026-10-12

Need a fire extinguisher inspection in Houston? Most businesses, restaurants, warehouses, and apartment complexes need a monthly visual check and an annual inspection (maintenance) by a licensed technician, plus periodic internal maintenance and hydrostatic testing depending on extinguisher type. This guide explains the difference between inspection, recharge, and hydrostatic testing, lays out the NFPA 10 schedule, gives estimated Houston cost ranges, and lists what to ask before you book.

Inspection vs recharge vs hydrostatic test

These three services get lumped together, but they're different jobs with different prices.

Service	What it is	When you need it
Monthly inspection	A quick visual check: in its place, unobstructed, pressure gauge in the green, pin and tamper seal intact, no visible damage. Staff can do this and initial/date the tag.	About every 30 days (NFPA 10)
Annual maintenance ("annual inspection")	A licensed technician examines the unit's mechanical parts, agent, and expelling means, then attaches a new service tag.	At least once every 12 months, and when an inspection finds a problem
Recharge / refill	The technician refills the extinguishing agent and repressurizes the unit.	After any use (even a short squeeze), when pressure is low, or as part of 6-year maintenance
6-year maintenance	Stored-pressure units with a 12-year hydro cycle (e.g., common ABC dry chemical) are emptied, inspected internally, and recharged.	Every 6 years from manufacture or last hydro
Hydrostatic test	The cylinder is pressure-tested with water to make sure the shell can still safely hold pressure.	Every 5 or 12 years depending on type (see the schedule below)

NFPA 10 schedule by extinguisher type

NFPA 10 (Standard for Portable Fire Extinguishers) sets these intervals. Your fire marshal enforces whatever edition the City of Houston has adopted, so treat this as a general guide and confirm with your service company.

Extinguisher type	Monthly inspection	Annual maintenance	Internal maintenance	Hydrostatic test
ABC / BC dry chemical (stored pressure, steel or aluminum shell)	Yes	Yes	Every 6 years	Every 12 years
Carbon dioxide (CO2)	Yes	Yes	Every 5 years	Every 5 years
Class K wet chemical (kitchens)	Yes	Yes	Every 5 years	Every 5 years
Pressurized water / foam (AFFF, FFFP)	Yes	Yes	Annually	Every 5 years
Halon / clean agent	Yes	Yes	Every 6 years	Every 12 years
Disposable (non-rechargeable)	Yes	Yes	n/a	Not tested. Remove from service 12 years after manufacture

Texas licensing: who can service your extinguishers

In Texas, companies and technicians who service portable fire extinguishers must be licensed through the State Fire Marshal's Office at the Texas Department of Insurance. A company needs a Fire Extinguisher Certificate of Registration, and a technician servicing portable units holds a Type B Portable Fire Extinguisher License (FEL-B). You can look both up with the SFMO company and individual search on the TDI website. Make sure the service tag lists that license number. A tag from an unlicensed vendor may not satisfy a Houston fire inspector or your insurer.

Estimated costs in Houston

These are rough national ranges we collected for planning. They are not quotes and not verified Houston prices. Route pricing, trip charges, unit size, agent type, and minimum service fees all change the total, so always get a written quote first.

Service	Typical range (estimate)	Notes
Annual inspection and tag, per unit	About $8–$25	Often cheapest when added to an existing route. Expect a trip or minimum fee for small jobs.
Recharge, ABC dry chemical 5–10 lb	About $25–$75	More if the unit also needs 6-year maintenance, a new valve stem, or an O-ring.
Recharge, CO2 or Class K	Usually more than ABC	Depends on agent and cylinder size. Get a quote.
Hydrostatic test	About $25–$80+ per cylinder	Often includes recharge. Many shops offer loaner units.
Replacement 5 lb ABC unit	Often comparable to recharge + hydro	For older, damaged, or overdue cylinders, replacing can be cheaper.

Refill vs replace

After any discharge, even a partial one, an extinguisher should be professionally recharged. Units that fail inspection, show corrosion or dents, have damaged hoses or gauges, or are past their hydrostatic test date are often cheaper to replace than to overhaul. Disposable units can't be refilled at all. Keep tags and service records with the unit for audits and insurance claims.

What to have ready for a Houston service visit

Make sure the extinguishers are reachable, with prior service tags visible, and have someone on site who can approve replacements. Know your building access hours and loading-dock rules, plus how many ABC, CO2, Class K kitchen, and clean-agent units you have. If a unit was discharged, tag it out of service and tell the technician which one. Restaurants should plan Class K service around their kitchen hood suppression system inspection, which is a separate service.

What to ask a Houston provider

Ask for their TDI license number, whether they offer same-day or next-day service, and whether they provide loaner units during hydrostatic testing. Ask for documentation that works for fire marshal and insurance audits, whether they service CO2, Class K, and clean-agent units, and whether they cover your area (Inside the Loop, Energy Corridor, Ship Channel, Sugar Land, The Woodlands, Katy, Pasadena).
