Carpenters insurance checklist: what a carpentry contractor should carry

The carpentry contractor insurance checklist

QUICK ANSWER

Carpenters usually carry general liability, workers' compensation and commercial auto. Carpentry contractors frame, trim and finish for general contractors and homeowners alike, work with power tools at height, and carry lumber and installed millwork that nobody insures until the job is accepted. The general contractor and the property manager 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 a carpentry contractor for what

Who	What they usually want to see
General contractors	General liability and workers' compensation with a waiver of subrogation, often primary and non-contributory wording and commercial auto
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

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.
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.
Builders risk or installation floater. The project limit, soft costs, theft from the site and the point at which coverage ends (acceptance or occupancy).

What usually goes wrong for carpentry contractors

Framing above three stories under a residential-rated policy.
Custom millwork destroyed on site before installation, uninsured because no installation floater was bought.
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 a carpentry contractor

The share of framing versus finish work, maximum height worked, and whether millwork is built in your own shop
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

Who covers lumber and millwork stolen or ruined on the job before it is installed?

An installation floater on your inland marine policy, or the project's builders risk if it names you. General liability does not pay for your own materials, and the owner's policy rarely does either until the work is accepted.

Framing contractors and finish carpenters: does the carrier see a difference?

A large one. Framing carries height, collapse and structural claims; finish work carries mostly completed-operations and property-damage exposure. Describe the actual split; a policy rated for trim work can be contested on a framing claim.

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 a carpentry 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 a carpentry 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.
