Reading a Contractor's Insurance Certificate

Asking for proof of insurance sounds adversarial and is not. It is a standard document that every established contractor issues routinely, usually within a day, direct from their insurance agent.

What the document is

A certificate of insurance is a one page summary produced by the insurer or their broker. It names the insured business, the policy numbers, the types of coverage carried, the limits on each, and the policy period. It is a summary of a policy, not the policy itself, which is why it is quick to produce and free.

The fields that matter

The named insured should match the business name on your quote and contract exactly. A certificate in the name of a related company, or a sole trader whose name differs from the trading name on your paperwork, is worth a question.

General liability limits, expressed as a per occurrence figure and an aggregate. The per occurrence number is the one relevant to a single incident at your house.

Workers compensation, which covers their employees for injury on your property. This is the coverage most likely to be missing on very small operations, and the one whose absence can most directly become your liability.

The policy period. A certificate that expired four months ago tells you what was true four months ago.

Getting it directly

The cleanest route is to ask the contractor to have their agent send it to you. A certificate that arrives directly from the insurance agency has not passed through anybody's photo editor. A photographed copy is usually fine and is worth a glance for inconsistent fonts or a date that does not sit right.

What a refusal means

Occasionally a small operator genuinely does not carry workers compensation because they have no employees and work alone, which is legitimate in many jurisdictions and is worth knowing before they bring a second person to lift a slab.

An outright refusal to provide anything is different, and is the clearest signal you will get at no cost. Back to Licensing, Insurance, and Silica Safety in the Stone Trade for the licensing and safety questions that go alongside it.

Additional insured, and when to ask for it

On larger projects a homeowner sometimes asks to be named as an additional insured on the contractor's general liability policy. It is a routine endorsement, it usually costs the contractor little or nothing, and it means the policy responds to a claim involving you rather than only to claims against the contractor.

For a countertop replacement it is more formality than necessity. For a full kitchen remodel with several trades in the house over weeks, it is a reasonable request and an established contractor will not find it unusual. If it is refused outright with no explanation, that is worth noting alongside everything else.

What the certificate does not do

It is a summary, not a guarantee. It confirms a policy existed on the date it was issued. It does not confirm the policy is still in force today, that premiums have been paid, or that the specific work being done falls within the policy's scope. Policies contain exclusions, and a general liability policy may exclude particular activities.

This is not a reason to skip asking. It is a reason to treat the certificate as one signal among several rather than as complete protection. The date on it and the name on it are the two fields that do most of the work.

Small operators and the honest exceptions

A skilled sole trader with no employees may legitimately carry general liability and no workers compensation, because in many jurisdictions there is nobody to cover. That is a defensible position and it is worth understanding rather than rejecting.

The follow up question is what happens when they bring a second pair of hands to lift a slab, because stone is not a one person job. If that person is a casual helper rather than an insured employee, an injury on your property has no policy behind it. Asking how the lift will be staffed is a practical question, not a suspicious one.

Where this sits in the decision

Insurance paperwork will rarely be the reason you choose one shop over another, and it should not be. Quality of work, slab selection, and how they talk about your kitchen matter more to the outcome you will live with.

What the paperwork does is remove a category of low probability, high consequence risk from the decision entirely, for the cost of one email. Ask, file the answer, and go back to thinking about the stone.

A proportionate approach

Match the effort to the scale of the work. For a single countertop replacement by an established local shop, asking for the certificate and glancing at the name and the dates is proportionate and takes a minute. For a full kitchen remodel with multiple trades in the house over several weeks, it is reasonable to ask for certificates from the main contractor and to confirm they hold them for their subcontractors.

For anything involving structural change, permits, or a contractor you have no local reference for, spend a little more time: confirm the certificate came from the agency, check the policy period covers your whole project rather than expiring midway, and consider asking to be named as additional insured.

The point is not to build a compliance process around a kitchen. It is to spend a few minutes on the one category of risk that is invisible, unlikely, and expensive, and then to stop thinking about it and get on with choosing the stone.

Ask for the certificate, check that the named insured matches your contract and that the policy period covers your project, confirm workers compensation is present or understand why it is not, and file it with the rest of the job paperwork. It takes one email and a minute of reading. It will almost never change your decision, and on the rare occasion it does, it will have saved you from the one kind of problem on a home project that is genuinely difficult to recover from.
