About this bond

What it is and who needs it.

What the bond actually guarantees

St. Louis County licenses Master Pipefitters through its Department of Public Works, and conditions the license on a $25,000 indemnifying bond. It's a compliance guarantee that you'll perform pipefitting work in accordance with the County code and the conditions of your Master's license.

It's a three-party arrangement: you (the principal), the surety carrier, and St. Louis County (the obligee). If you violate the code or a permit condition and the County or a harmed party suffers a loss, they can recover against the bond up to $25,000.

It is not insurance for you — if the surety pays a claim, you repay the surety. The bond must stay active for the life of your license, so we track it and send renewal notices 60 and 30 days out to keep your filing continuous.
