What it is and who needs it.
What the bond actually guarantees
Washington licenses plumbing contractors through the Department of Labor & Industries, and RCW 18.106.410 conditions that license on a $6,000 continuous surety bond with the State of Washington named as obligee.
It's a three-party arrangement: you (the principal), the surety carrier, and the State of Washington (the obligee), with the public protected. The bond stands behind your obligation to pay taxes and wages and to perform the plumbing contracts you take on; a harmed party can recover against it.
The bond is continuous — if the surety cancels or withdraws, your plumbing contractor license is automatically suspended until a new bond is filed and approved. So we keep it continuous and notify you well ahead of any lapse. If the surety pays a claim, you repay the surety.

Claims, renewal, filing, and what sets the price.
If a claim is made
A claim comes from the party the bond protects, the obligee named on the form, when the duty the bond guarantees is not met.
The surety investigates and pays a valid claim, up to the $6,000 bond amount. You then repay the surety: a surety bond is a guarantee of your performance, not insurance for you.
Renewal and term
The premium covers a one-year term from the effective date you choose; a longer term is the same price per year, chosen at checkout.
Renew before the expiry date to keep the bond in force: the license, permit or contract it backs expects continuous coverage.
How to file it
File with Labor & Industries. Your executed continuous bond and power of attorney arrive by email, ready to file with your L&I plumbing contractor license. Wet-ink original mailed on request.
What sets the price
The premium is fixed at $100 at the $6,000 amount for every applicant: the carrier’s rate book prices this bond by the form, not by your credit or your business profile.
