Plumbing is the trade where a small mistake produces a large claim. A fitting that fails, a line left unsecured, a connection that leaks slowly behind a wall — the repair costs very little and the damage costs a great deal.

That asymmetry drives everything about how plumbing contractors should be insured, and it is why the cheapest general liability policy tends to be the wrong one for this trade.

Water Damage Is the Defining Claim

When water gets loose inside a finished building, it moves through flooring, drywall, cabinetry, insulation, electrical systems, and everything the owner keeps there.

In multi-unit and high-rise buildings, the exposure multiplies. A supply failure on an upper floor of a condominium or hotel travels downward through units the plumber never entered. One incident generates claims from multiple owners, the association, their insurers, and potentially a business interruption claim from a commercial tenant.

For contractors doing condominium, hotel, apartment, or commercial work in South Florida, this is the exposure that should set the liability limit — not the size of the crew or the value of the truck.

Slab leaks deserve separate mention. Florida’s slab-on-grade construction means supply lines run under concrete, and a failure there is expensive to locate and expensive to repair, with damage that develops out of sight.

What General Liability Actually Pays For

The distinction that determines what a claim costs you out of pocket.

A standard general liability policy does not pay to redo your own defective work. The “your work” exclusion removes that. What responds is the resulting damage.

Applied to plumbing: if a failed connection floods a building, the policy may cover the damaged flooring, drywall, and contents, but it will not cover returning to replace the fitting and redo the work.

Care, custody, and control is the second provision. Policies generally exclude damage to property in your control and to that particular part of real property you are working on. Since plumbing service happens inside occupied homes and businesses surrounded by finished property, this language gets tested constantly.

Both are worth confirming on your specific policy rather than in the abstract.

Hot Work Starts Fires After You Leave

Soldering, brazing, and torch work happen routinely inside walls, ceilings, and crawl spaces near combustible framing and insulation.

The problem is timing. Heat travels along piping and into concealed cavities, and a fire frequently develops hours after the crew has gone. Losses of this kind are severe and often occur overnight in unoccupied buildings.

A written fire watch procedure with a defined monitoring period after the last hot work of the day is the single most effective control. Extinguisher availability, heat shields, and documented training matter too, and carriers ask about all of it.

If your company performs torch work, disclose it at application rather than at claim time.

Sewage, Grease, and the Pollution Exclusion

This is the gap most plumbing contractors do not realize applies to them.

Standard general liability policies contain a pollution exclusion barring coverage for bodily injury and property damage arising from the discharge, dispersal, release, or escape of pollutants. Sewage and wastewater fall within that definition in many forms.

The exposures are routine for this trade:

A sewer line failure releases wastewater into a building or onto a property. A grease interceptor overflows at a restaurant. A drain cleaning operation backs sewage into a unit. A sewer repair discharges to soil or groundwater. Chemical drain cleaners cause damage or injury.

Contractors pollution liability addresses these. For a company doing sewer, drain, or grease waste work, it is not a peripheral coverage — it fills a hole sitting over ordinary daily operations.

Backflow and Cross-Connection

Backflow prevention exists to keep contaminated water out of the potable supply, which means a failure has consequences beyond the building.

A cross-connection that allows contamination into a municipal system creates exposure involving the utility, public health authorities, and potentially many affected parties. Improper installation, an untested assembly, or a certification that lapsed all become part of that analysis.

For contractors holding backflow certifications and performing testing under contract, this is also a professional exposure — the work involves certifying that a system meets a standard, and a general liability policy is not designed to respond to a professional judgment.

The same applies to medical gas systems. That work carries certification requirements and consequences that most carriers underwrite specifically. If your company performs it, confirm it is disclosed and accepted rather than assumed.

Completed Operations and the Statute of Repose

Plumbing failures surface long after the invoice is paid. A connection installed today can leak in three years, and the claim arrives against work completed under a policy that may no longer be in force.

Completed operations coverage responds to claims from finished work. Florida’s statute of repose, shortened from ten years to seven by Senate Bill 360 in 2023, generally runs from the earliest of the certificate of occupancy, certificate of completion, or abandonment of construction, with four years from discovery on the limitations side.

Confirm your completed operations limits meet your largest contract requirement, and confirm there is no gap between the coverage in force when past work was performed and what you carry now.

Excavation and Utility Strikes

Sewer and water service work means opening the ground, and Florida properties carry gas, electric, communications, irrigation, and septic systems running in places no plan shows.

Florida requires notification before excavation, and documented locate tickets are the first thing anyone asks for after a strike. A gas line strike is a severe claim. A fiber cut is an expensive one. Both are largely preventable.

Trench safety applies as well — unprotected excavations remain among the most dangerous conditions in construction.

Service Fleets Carry Real Auto Exposure

Plumbing companies run more vehicles per employee than most trades, and those vehicles cover high mileage across residential and commercial routes all day.

Emergency service adds a factor other trades do not have: night driving, fatigue, and technicians responding under time pressure. Both frequency and severity rise.

Confirm that hired and non-owned auto coverage is in place for employees using personal vehicles, that drivers’ records are checked at hire and periodically after, and that the liability limit reflects what a serious accident involving a service vehicle actually produces.

Technicians Work Inside Occupied Property

Service plumbing means employees in homes and businesses, frequently alone, sometimes with keys or access codes.

Allegations of theft from a customer’s property are a recurring problem, and general liability does not respond to employee dishonesty. Employee dishonesty coverage or a fidelity bond addresses it, and background screening reduces the frequency.

Subcontractors and the Audit

Plumbing companies subcontract excavation, concrete, drywall repair, and specialty work, and use subcontracted labor during busy periods.

A subcontractor who cannot produce a current certificate showing their own general liability and workers’ compensation typically has their payroll charged back to you at audit as if they were your employee. Collect certificates before work begins, confirm they cover the full project period, and keep them.

Tools, Equipment, and Contract Requirements

Plumbing equipment travels constantly — cameras, locators, jetters, augers, press tools, pumps, and threading equipment — and a standard commercial property policy covers property at a described premises, not at jobsites and in vans. Inland marine coverage is what reaches it.

On commercial and association work, expect requirements for specified limits, additional insured status covering ongoing and completed operations, waiver of subrogation, and primary and non-contributory wording. Condominium and hotel contracts tend to carry the most demanding terms, driven by the water damage exposure above.
