Fire Supression Contractors

Most fire suppression contractors need general liability, workers' compensation, commercial auto, inland marine (tools and equipment), and errors & omissions coverage. If you install, service, inspect, or repair sprinkler systems, fire alarms, kitchen hood suppression, or special hazard systems, your general liability policy must include both ongoing operations and completed operations coverage — and it should be written by a carrier that understands fire protection work.

MBG Insurance offers a fire suppression contractor program written with an admitted carrier, with E&S options available for harder-to-place risks.

Ongoing operations covers claims that happen while you're actively working on a job — a sprinkler head knocked loose that floods a finished office, a dropped tool that injures someone below your lift, or damage to a client's property during installation.

Completed operations covers claims that arise after the job is finished and you've left the site — a fitting that fails six months later, or a system that doesn't perform during a fire two years after installation. For fire suppression contractors, this is where the largest claims live, because your work is tested at the worst possible moment. Both coverages should be included in your general liability policy, and neither should be excluded or restricted.

Fire suppression work involves professional judgment — hydraulic calculations, system design decisions, code compliance, inspections, and certifications. If a claim alleges your professional error caused a loss (for example, a system you designed or certified failed to perform), a standard general liability policy may not respond, because most GL policies exclude professional services.

E&O coverage fills that gap. Paired with completed operations coverage, it protects you when a claim surfaces long after the job is done and alleges a mistake in design, inspection, testing, or certification — not just faulty installation. For contractors who inspect and tag systems, this coverage is essential.

Yes — but your policy needs to be written for it. Fire extinguisher work carries a products liability exposure most trades don't have: if an extinguisher you sold, recharged, or tagged fails to discharge during a fire, the resulting claim falls on you. Your general liability policy should include products and completed operations coverage that specifically contemplates extinguisher sales and service, and your operations should be accurately classified so a claim isn't denied over a misdescribed business.

If you also perform hydrostatic testing or six-year maintenance, tell your agent — these services affect how your policy should be structured.

Once you select and pay for your policy, MBG Insurance can typically issue your certificate of insurance the same day. The quote process itself takes 24 to 48 hours after you submit your basic business information. Having your annual revenue, number of employees, and services offered ready will help speed up the process.

If a system you installed, serviced, or inspected fails to perform and a fire causes property damage or injury, the claim will typically involve your completed operations coverage — and possibly your E&O coverage if the allegation involves design, inspection, or certification errors. These claims can be catastrophic, involving total building losses and business interruption damages, which is why many fire suppression contractors carry a commercial umbrella policy on top of their general liability limits.

Yes. Inspection, testing, and maintenance (ITM) work creates professional liability exposure every time you sign or tag a system. If a system you passed fails later, the claim will point to your inspection. E&O coverage designed for fire protection contractors is the right protection here — standard GL alone is not enough.

Premiums are based on your payroll, revenue, the mix of work you do (installation vs. service vs. inspection), and whether you work on residential, commercial, or high-hazard properties. A solo contractor doing extinguisher service pays far less than a multi-crew company installing systems in commercial new construction.

As an independent agency, MBG Insurance shops your coverage across multiple carriers — including our admitted market fire suppression program — to find competitive pricing. Most quotes are returned within 24–48 hours.
