Your Proportioner Goes Down on a Job — Is Your Equipment Covered?

It's the call every spray foam contractor dreads. You're mid-job, the proportioner goes down — a pump failure, a heater element, a ratio imbalance that forces a full shutdown. The job stops. The client is frustrated. The equipment is on the back of your rig, forty miles from the shop, and the repair tech is hours out.

The machine is down. The job is delayed. What does your insurance actually pay for?

Standard Property Coverage Won't Help

A standard commercial property policy covers your fixed location — your shop, your office, your storage. The moment your proportioner is loaded onto a trailer and driven to a job site, it's off-premises and almost certainly excluded from your property coverage.

Most spray foam contractors discover this gap too late: after a proportioner failure, a theft from a job site, or a rig fire on the highway. Standard property wasn't designed for equipment that moves.

Inland Marine / Tools-and-Equipment: the Coverage That Fits

The fix is inland marine coverage — also called tools-and-equipment coverage — which follows your equipment wherever it goes. A well-structured policy covers:

• Proportioners and spray systems — the core of your production capability
• Hose sets, guns, and applicator heads — consumable but expensive
• Generators and air compressors on the rig
• Theft from a job site or vehicle — a major exposure when equipment is left in trailers overnight
• Transit damage — equipment damaged while being transported between jobs
• Accidental damage — a drop, a crush, a hose rupture under pressure

This coverage goes with your equipment — to the job site, to the shop, and everywhere in between.

What a Proportioner Is Actually Worth

It's more than people think. A commercial heated proportioner — the kind needed for closed-cell two-component work — runs $40,000 to $80,000 or more, depending on the configuration. A full rig with generator, hoses, and truck can represent $100,000 to $150,000 in assets.

Now consider what it costs to be without that rig for a week while waiting on a repair or a replacement. Missed project milestones, contract penalty clauses, and a crew standing idle add up fast. Getting a replacement proportioner on short notice — if you can find one — is expensive.

The equipment coverage limit needs to reflect the real replacement value of everything on your rig, not just what you paid for it years ago.

Equipment Breakdown vs. Inland Marine

These are two different coverages, and spray foam contractors often need both:

• Inland marine covers external causes — theft, fire, transit accident, job-site damage.
• Equipment breakdown covers internal mechanical or electrical failure — a pump motor burning out, a heater element failing, an electronic control malfunction.

A proportioner that fails due to an internal component failure is an equipment breakdown claim, not an inland marine claim. If your policy only has one or the other, you have a gap.

What to Check on Your Current Policy

Review your current coverage and look for three things:

1. Off-premises equipment coverage — does your policy cover equipment at job sites and in transit, or only at your fixed location?
2. Inland marine / tools-and-equipment schedule — are your proportioner, rig, guns, and generator individually scheduled at their current replacement values?
3. Equipment breakdown coverage — is internal mechanical and electrical failure covered, separate from external causes?

If any of those three are missing or thin, a proportioner failure or a rig theft could be a largely uncovered five- or six-figure loss. We build tools-and-equipment coverage with proper limits on every spray foam program — because for a spray foam contractor, the rig is the business.
