Irrigation contractors insurance checklist: what an irrigation contractor should carry

The irrigation contractor insurance checklist

QUICK ANSWER

Irrigation contractors usually carry general liability, workers' compensation and commercial auto. Irrigation contractors trench through yards where utilities and other contractors' lines run, connect to potable water under backflow rules, and leave behind systems that flood basements and freeze pipes when they fail. The property manager and the permit office ask for proof of each. The checklist below says what every item does, who requires it and how to check it on the policies you already have.

Who asks an irrigation contractor for what

Who	What they usually want to see
Property managers & HOAs	General liability with the manager and owner as additional insureds, and workers' compensation
Cities, counties & permits	General liability, auto and workers' compensation at the limits in the permit or contract
Banks, lenders & SBA loans	Property or auto physical damage with the lender as loss payee, and liability proof at closing and every renewal

Each of them wants a certificate, and most want it again at every renewal. A live certificate link from the wallet shows today's coverage to every holder and tells them when it changes.

How to check what you already have

General liability declarations page. Three liability numbers matter: each occurrence, general aggregate and the products–completed operations aggregate. Then the forms list: blanket additional insured, waiver of subrogation and primary and non-contributory wording satisfy every contract; scheduled forms satisfy one.
Workers' compensation information page. Item 3.A must list every state you work in, item 4 must carry the right class codes, and the employers' liability limits should meet what contracts ask. Check that the estimated payroll is close to this year's.
Auto schedule. Every vehicle listed with the right garaging address and use; symbols that include hired and non-owned auto; physical damage with the lender as loss payee where the vehicle is financed.
Equipment schedule. Owned items scheduled above the per-item threshold, a blanket limit for small tools, leased or rented equipment included, and the valuation (replacement cost or actual cash value).
Umbrella schedule of underlying insurance. Each primary policy listed with the limits the umbrella expects; a gap between the two is uninsured.
Bonds. The obligee (board, municipality or owner), the penal sum and the expiry date; a bond is renewed with the licence or the job, not with the policy year.
Hired and non-owned auto. Look for the symbols 8 and 9 or an endorsement by that name on the auto or general liability policy; without it, staff in their own cars are uninsured on company business.
Pollution liability. Site-based or contractors form, claims-made or occurrence, the materials named (mold, asbestos, lead, fuels), and transport and disposal coverage.

What usually goes wrong for irrigation contractors

A backflow device missed or failed, which is a public-health claim as much as a plumbing one.
A struck gas line in a yard with the underground exclusion still on the policy.
Damage to the exact thing you are working on is excluded on most general liability forms; installation floaters and care, custody and control endorsements fill that hole.
A completed-operations aggregate quietly limited by endorsement; the declarations page looks fine until the forms are read.
Theft from a locked truck overnight with no tools floater, or a per-item limit lower than the one tool that mattered.
A personal auto policy on a truck with the company name on the door.

What underwriters will ask an irrigation contractor

Residential versus commercial share, whether the business holds a backflow certification, and utility-locate practice
Residential versus commercial split of the work
Whether any work is done above three stories or below grade
Years of completed-operations coverage with no gap
Whether you warranty your work and for how long
Total value of hand and power tools kept on the trucks

Have the answers in the wallet before the renewal and the quote request fills itself in; CoverMatch sends one application to every eligible carrier and lines the quotes up against what you have.

Renewal timing

Audits at year end compare payroll, receipts and subcontractor costs with the estimate, so keep the wallet's size figures and the subcontractor certificates current. Start comparing sixty days before expiration, and ask for the limits the next contract will need rather than the ones the last one did.

Questions people actually ask

Does general liability cover a utility strike while trenching?

Only when the XCU exclusion is removed. Irrigation trenching strikes lines more often than almost any other residential trade, and the exclusion is the first thing to check on the forms list.

Is a flooded basement from a failed valve covered?

As a completed-operations claim, yes, when the policy in force includes completed operations. Winterization records matter: the claim often arrives after the first freeze, and the service log decides whether the system was blown out.

Does general liability cover damage to a customer's property while I work on it?

It covers damage to the rest of their property, not usually the part in your hands. Many forms exclude property in your care, custody or control, so an irrigation contractor that handles valuable items or systems needs an endorsement or an installation floater. The policy explainer in the wallet flags the exclusion when it reads your policy.

A job I finished two years ago just caused damage. Which policy pays?

The general liability policy in force when the damage happens, as long as it still includes completed operations and you kept the coverage continuous. A gap or a switch to a form that excludes completed operations is how an irrigation contractor ends up uninsured for old work.

Are tools stolen from my truck covered?

Under a tools floater, yes, subject to the deductible and any per-item limit. Under the commercial auto policy, no: auto covers the vehicle, not what was in it.
