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 Chapter 6, § 6.03.001(B)(2) (Department of Land Use)New Castle County licenses contractors through its Department of Land Use under Chapter 6 (“Building Code”) of the New Castle County Code. Section 6.03.001(B)(2) requires each applicant for a permit contractor endorsement to file a surety bond naming the County as beneficiary and the contractor’s business entity as principal, issued by an A-rated surety company authorized to do business in Delaware and kept current for the entire license period. The bond indemnifies the County against loss, damage or expense connected to the licensed work and covers the cost of enforcing Chapter 6, including unpaid administrative fees and fines; on the Department’s form it also secures the contractor’s compliance with the County Code and with Delaware and federal law. The Code leaves the amount to the bond schedule in the Department’s Chapter 6 Appendix (Appendix 4), and the Department’s annual Statutory Compliance Bond form lists the amount for each category, from the building classes to the utility trades: confirm the figure for yours on the form. License rules for each trade are in § 6.03.006 (building), § 6.03.007 (mechanical and HVACR), § 6.03.008 (plumbing), § 6.03.009 (decorative appliance) and § 6.03.010 (sewer and drain cleaner, outside utility).

After you buy

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 $10,000 bond amount. You then repay the surety: a surety bond is a guarantee of your performance, not insurance for you.

Renewal and term

The bond runs to January 1 whatever day you buy; the premium covers the period to that date.

Renewal falls on the statutory date, January 1, in the year your term ends.

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 the Department of Land Use. Your executed bond and power of attorney arrive by email, ready to file with your New Castle County master plumber license for the 2026–2027 term. Wet-ink original mailed on request.

What sets the price

The premium is fixed at $100 at the $10,000 amount for every applicant: the carrier’s rate book prices this bond by the form, not by your credit or your business profile.

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 the 2026–2027 term is set up as its own listing — pricing is $100 flat either way.

Do I pay the $10,000?No. You pay $100. 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 Chapter 6 of the New Castle County Code. No active bond, no license.

Is there a credit check?No credit check: the application collects no credit information. Most applications approve instantly.

When does it renew?New Castle County contractor bonds run on a statutory January 1 renewal. This bond runs to January 1 whatever day you buy, and renews from that date; we send renewal notices 60 and 30 days out, with autopay available, so your license never lapses over a missed email.

Which A-rated carriers underwrite these bonds?Typically Arch Insurance Company (A.M. Best A+) or Nationwide Mutual Insurance Company (A.M. Best A). Which one writes your bond depends on the bond type and your state. The carrier's name and official signature are printed on the bond you receive.
