State guidance for Delaware
For plumbing in Delaware, prepare access to the affected fixture, shutoffs, mechanical area, drain, or buried line. Confirm the inspected scope, credentials, permits, inspections, exclusions, and restoration responsibility before authorizing work.
Credential verification
Plumbing in Delaware is regulated by the Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners within the Division of Professional Regulation, whose statutory authority is in Title 24, Chapter 18 of the Delaware Code. For most plumbing work, hire a licensed plumber and verify the license through the state's DELPROS online license-verification system before work begins.
The Board licenses Master Plumbers, along with Master HVACR and Master Restricted HVACR licenses for heating, ventilation, air conditioning, and refrigeration work. A Master Plumber is the credential to confirm for plumbing jobs, so it is reasonable to ask which license a contractor holds for the work you need.
Permits and inspections
Plumbing permits and inspections in Delaware are administered by the state Plumbing Permit and Inspection Program in the Division of Public Health, which permits and inspects work statewide except where a local jurisdiction runs its own program. Permits are issued to Delaware-licensed plumbers and, for owner-occupied homes not for sale or lease, to homeowners. Because New Castle, Kent, and Sussex counties and some municipalities maintain their own building departments, always confirm whether the state program or a local office handles your address.

Plumbing in Delaware: FAQs
How do I prepare for plumbing in Delaware?
Document whether the symptom is isolated, shared by several fixtures, or affecting the whole property and prepare access to the affected fixture, shutoffs, mechanical area, drain, or buried line. Ask the professional to confirm the inspected scope, credential, permit responsibility, and exclusions in writing.
Does Delaware guidance diagnose my plumbing problem?
No. State information helps with credential, permit, and planning questions. The cause, responsibility, and repair or project scope still need to be confirmed for the specific property.
What does a plumber actually handle?
Most plumbing professionals handle leaks, clogged and slow drains, sewer lines, water heaters, pipes, toilets, faucets, sinks, garbage disposals, and sump pumps. If you are unsure who to call, describe the symptom and Plumbing Advisors can help point you to the right service.
How do I know if my plumbing issue is urgent?
Active leaking water, sewage backups, a burst pipe, or no water at all are usually urgent. Slow drains, minor drips, and a running toilet are important but typically not emergencies. When in doubt, call and describe what you are seeing.
Should I shut off my water before calling?
If water is actively leaking and the shutoff is safe and accessible, turning it off can prevent damage. You can shut off an individual fixture valve or the main water valve for the home. Avoid using the affected fixture until it is inspected.
Does Plumbing Advisors do the repair?
Plumbing Advisors is a connection and guidance service. We help you understand the problem and connect you with plumbing professionals that service your area. The professional you are connected with performs the work.
