What it is and who needs it.
What the bond actually guarantees
New Castle County licenses master plumbers through its Department of Land Use, and conditions the license on a statutory compliance bond. This listing is the bond on the 2026–2027 statutory term. The bond is a code-compliance guarantee: it stands behind your compliance with the New Castle County Building Code and the Delaware laws that govern plumbing work.
It's a three-party arrangement: you (the principal), the surety carrier standing behind you, and New Castle County (the obligee), with the public protected. If a licensed plumber violates the building code or the County’s contractor ordinance and someone is harmed, they can recover against the bond.
The bond must stay active for the life of your license. New Castle County contractor bonds run on a statutory January 1 renewal, so we track the date and notify you 60 and 30 days out, keeping your $10,000 filing continuous.
