About this bond

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.

New Castle County Code § 12.05.090 (Department of Land Use)New Castle County licenses contractors through its Department of Land Use and conditions the license on a statutory compliance bond under New Castle County Code Chapter 12.05. The bond guarantees the contractor's compliance with the New Castle County Building Code and all applicable Delaware laws affecting the trade, and covers work performed during the License Period. The required amount is set by the Department of Land Use by license class — confirm the figure against your license category on your application.

FAQ

Common questions.

How is this different from the other master plumber listing?It is the same $10,000 master plumber bond, on the 2026–2027 statutory term. New Castle County contractor bonds run on a fixed January 1 renewal, so each term year is set up as its own listing — pricing starts from $100 either way, with most applicants qualifying at or near the minimum.

Do I pay the $10,000?No. Your premium is variable, from $100 depending on your credit tier. The $10,000 is the surety's maximum liability if a valid claim is made against the bond — not a deposit, and nobody holds your money.

Who requires this bond?The New Castle County Department of Land Use requires it as a condition of a master plumber license, under the County’s contractor licensing chapter. No active bond, no license.

Is there a credit check?The application collects no credit information, and most applications approve instantly at or near the minimum price. If a check ever runs, it's a soft pull only — never a hard inquiry, and it never affects your score.

When does it renew?New Castle County contractor bonds run on a statutory January 1 renewal. You can buy a 1, 2, or 3-year term; we send renewal notices 60 and 30 days out, with autopay available, so your license never lapses over a missed email.
