Contractor insurance

Plumbing contractor insurance

Plumbing has a defining exposure that shapes everything else: a connection that fails can release water continuously into a building for hours. The value of the part is irrelevant to the size of the claim.

What the work usually involves

Service work, new construction and drain work each behave differently from an insurance standpoint, and the mix matters.

  • Service calls, repairs and fixture replacement
  • Water heater installation and replacement
  • Rough-in and finish plumbing in new construction
  • Repipe and remodel work in occupied homes
  • Drain cleaning, sewer service and camera inspection
  • Water and sewer service line excavation
  • Gas piping and appliance connections, where performed

Risks worth talking through

Water released into a finished building

This is the claim that defines the trade. A supply connection that fails overnight in a finished home or an occupied commercial building can produce a loss in the hundreds of thousands of dollars from a fitting worth a few dollars.

Claims that appear long after the work

A slow leak inside a wall may not be discovered for months. Completed work exposure is central here, and continuity of coverage across years can matter more than in trades where problems appear immediately.

Torch and soldering work

Open flame in a joist bay or wall cavity creates a fire exposure that is very similar to the one mechanical contractors face, and it is often overlooked in a trade people associate with water.

Water heaters and pressure

Improper relief valve, venting or expansion arrangements produce failures that can be sudden and severe, and gas-fired units add a combustion exposure.

Drain cleaning and sewer work

Cable and jetting work can damage older pipe, and the customer will generally view the damage as something you caused. Excavation for service lines adds buried utility strikes and trench safety.

Working in occupied homes

Access to finished spaces, customer belongings and the need to shut water off to a building all create exposures separate from the plumbing itself.

Coverage areas to review

General liability

General liability may help address claims alleging bodily injury or damage to someone else's property arising from your operations. Coverage depends on the policy terms and exclusions. Understanding how your policy treats damage caused by your work, as distinct from the cost of correcting the work itself, is the single most useful thing to review.

Workers compensation

If you have employees, the exposures are burns from torch work, cuts, lifting water heaters and fixtures, confined space and trench work where excavation is involved, and exposure to sewage in drain work.

Commercial auto

Service vans and trucks, plus trailers or equipment for excavation and jetting. Vehicles are usually stocked, taken home by technicians and driven on emergency calls, all of which are worth discussing.

Tools, van inventory and equipment

Jetters, cameras, pipe machines, press tools and torches represent significant value, and much of it lives in vehicles overnight. Material purchased for a job and staged on site before installation is commonly handled separately from your liability policy.

This page is general information, not legal, safety or coverage advice. What a policy actually covers depends on your business operations and on the policy, carrier, terms, conditions, limits and exclusions that apply. Nothing here confirms eligibility or guarantees that any coverage is available to you.

What to have ready for a review

  • Approximate split between service, new construction and remodel work
  • Whether you perform drain cleaning, sewer or excavation work
  • Whether you perform hot work, and your procedure for it
  • Whether you install or service gas appliances
  • Number of service vehicles and typical inventory value in each
  • Whether you offer after-hours emergency service
  • Employee count and payroll
  • Any claims or incidents from the last several years

Questions we hear

A fitting we installed failed six months later and flooded a basement. Is that covered?

This is the completed work question, and it is the one worth reviewing carefully before it happens. Policies generally distinguish between the cost of fixing your own work and the water damage that failure caused to everything else. The second is usually where the money is, so understanding how your policy treats it matters.

We cabled an old drain line and it collapsed. Whose problem is that?

The customer will bring it to you, and whether the pipe was already failing is often disputed. Camera footage taken before you start is genuinely useful in these situations, both for the claim and for the conversation with the customer.

Do plumbers really need to worry about fire?

Yes. Soldering in a wall or joist bay is open flame inside combustible construction, and plumbing operations are a recognized source of structure fires. If your crews use a torch, it belongs in the conversation alongside the water exposure.
