Off-Ratio Coverage for spray foam contractors

Coverage for off-ratio spray foam events — when the A:B component ratio is wrong, foam doesn't cure correctly, and the resulting property damage, chemical exposure, and removal costs land in a gap most GL policies explicitly exclude.

Off-Ratio Coverage — spray foam insulation contracting

What it covers

  • Property damage from improperly cured spray foam that must be removed
  • Third-party bodily injury from chemical exposure due to off-ratio foam
  • Costs to identify and remove defective foam from a structure
  • Defense costs when an off-ratio event results in a lawsuit
  • Chemical release claims from incompletely reacted isocyanate or polyol
  • Remediation and restoration costs following an off-ratio application

Who it's for

  • Any spray foam contractor using two-component spray polyurethane foam systems
  • Contractors whose GL policy excludes or sublimits off-ratio events
  • High-volume commercial applicators with greater exposure to equipment malfunction
  • Residential contractors working in occupied homes where off-ratio exposure is a tenant risk

Why CCA

  • We access specialty markets that write off-ratio as a distinct, insurable risk
  • Off-ratio coverage coordinated with CPL so chemical exposure from incomplete reactions is also covered
  • Claims handling with adjusters who understand spray foam chemistry — not generic property adjusters
Off-Ratio Coverage — FAQ

Common questions about off-ratio coverage

Spray polyurethane foam is a two-component system — isocyanate (A-side) and polyol (B-side) — that must be mixed at a precise ratio for the foam to cure correctly. When equipment malfunctions, heaters fail, or a setup error occurs, the ratio goes off. The result is foam that doesn't cure, remains tacky, off-gasses incompletely reacted isocyanate, and can cause serious property damage and bodily injury.

Most GL policies have language excluding damage arising from the insured's own product or work that is defective, or from chemical releases treated as pollution events. An off-ratio foam application can be classified as either a defective product or a pollution release — and both exclusions can apply. Off-ratio coverage is written to address this specific gap.

More common than most contractors realize. Equipment heater failures, hose blockages, pressure imbalances, and cold-weather application can all produce off-ratio foam. Even experienced applicators working with well-maintained equipment face off-ratio risk on every job.

No. Contractor Pollution Liability covers third-party bodily injury and property damage from chemical releases — VOCs, isocyanates, and blowing agents. Off-ratio coverage addresses the defective-product aspect — foam that didn't cure right and the property damage from removing it. For full protection, you want both, coordinated.

Manufacturer warranties typically cover product defects — issues with the chemical itself. An off-ratio event caused by equipment malfunction or applicator error is not a product defect and is not covered by the manufacturer's warranty. That's a contractor liability — which is exactly what off-ratio coverage addresses.

Cost is driven by annual revenue, crew size, job type (residential, commercial, roofing), states where you operate, equipment values, and loss history. We quote your actual operation in about 15 minutes — never a ballpark from a generic contractor form.

Yes. Contractors Choice Agency is licensed in all 50 states and writes spray foam programs nationwide — Texas, Florida, the Northeast, Midwest, California, Mountain States, and everywhere spray foam contractors operate.

Typically 15 minutes on a call. Larger or higher-risk programs may take a day or two to place with the right markets, but we move fast and set expectations up front.

Often yes. We have admitted and E&S markets for spray foam contractors declined over CPL history, prior claims, or other issues. Bring us your situation and we'll find a market.

Usually yes. A coordinated program — especially one that aligns GL and CPL — closes the gaps where most spray foam claims fall and is typically cheaper than separate policies from separate carriers.

A.M. Best ratings reflect a carrier's financial strength. We place coverage with A-rated carriers so the coverage is there when an off-ratio event, a pollution claim, or a property-damage lawsuit hits.

Yes. Residential foam contractors carry completed-operations and off-ratio exposure; commercial contractors add higher limits requirements, GC bonding, and larger pollution exposure. We tailor the program to your actual work mix.

Completed-operations covers claims that arise after the job is done — foam that off-gasses, expands incorrectly, or causes property damage. These claims need to be explicitly included in the GL policy; many generic contractor forms sub-limit or exclude spray foam completed-ops.

Annual revenue, crew size, job types (residential, commercial, roofing foam), equipment list and values, states where you work, current coverage, and loss history. The more detail, the more accurate and competitive the quote.

It depends on the structure. If you 1099 subs, you need to verify they carry their own GL and workers' comp — or add them as additional insureds. We help you structure a program that doesn't create gaps when subs are on your jobsites.

Yes, though some markets are more restrictive for startups. Having proper PPE, documented safety protocols, and trained applicators makes placement easier and pricing more competitive. We'll help you document what underwriters want to see.

Tools and equipment coverage pays for the stolen equipment. Standard commercial auto covers the vehicle, but the spray gun, hoses, and proportioner on it need dedicated inland marine or tools coverage to be insured against theft or damage on a jobsite.

Yes. If you operate multiple spray rigs and crews, we build one coordinated program covering all vehicles, equipment, and workers with no gaps — including fleet auto and a blanket tools policy.

We help you understand what underwriters require in terms of applicator certification (SPFA training, BPI, etc.) and can structure your program to reflect your crew's credentials, which can improve both placement and pricing.
