IroncladMutual

A carrier built by people who built bridges

Ironclad Mutual is owned by its policyholders. There is no external shareholder whose return has to come out of a claim settlement.

The Cuyahoga valley, where the company started

Why the drawings

Four foremen from the Cuyahoga bridge shops started this company in 1948 because no carrier would write the trades they worked with at limits that meant anything. They were used to load ratings, tolerances and inspection reports, and they could not understand why a contract that decided whether a family kept its house was written to be difficult to read.

That is still the argument. A policy is a load path. It either carries what you put on it or it does not, and you should be able to see which before the load arrives rather than after. So we publish the form numbers, the limits, the deductibles, the exclusions and the licensing schedule, and we put the figures in a typeface where the columns line up.

A mutual company is owned by the people it insures. There is no separate shareholder return to protect, which does not make us saints, but it does remove one specific pressure that sits behind a lot of bad claims decisions in this industry.

1994
Business owner policies opened to the trades, then to practices and retail.

Single deductible per event adopted across the bundle tiers, ahead of the market.

How to check a carrier, including this one

Two public sources will tell you more about any carrier than its own website ever will. Use them on us and on everyone else you are considering.

NAIC complaint index1.00 = median
Published by the National Association of Insurance Commissioners and normalised for company size, so a large carrier and a small one can be compared directly. Below 1.00 means fewer confirmed complaints than expected for that volume of premium.
AM Best financial strengthA++ to D
An independent estimate of the carrier's ability to meet its obligations to policyholders. It matters most in the years you hope never happen, when a large number of claims arrive at once.
State department of insurancePer state
Every state regulator keeps a public record of a carrier's licence status and any enforcement action. Our licensing schedule lists the regulator for each of the fourteen states we write in.
