Indiana Plumbing — FAQ
Common questions about licensed plumbers in Indiana: credentials, costs, permits, and what to know before hiring.
Does Indiana require a plumbing license?
Yes. Indiana requires plumbing work to be performed by or under the direct supervision of an IPLA-licensed Plumbing Contractor. The license requires passing a state exam and meeting continuing education requirements. Performing plumbing work without a license is illegal and can result in fines, failed inspections, and voided homeowner's insurance.
How do I verify a plumber's license in Indiana?
You can verify any Indiana plumbing contractor license at the Indiana Professional Licensing Agency's online verification portal (mylicense.in.gov/everification). Search by the contractor's name or license number. Every profile on this site shows the plumber's IPLA license number so you can verify it independently before hiring.
How much does a plumber cost in Indiana?
Plumbing costs in Indiana vary widely by job type. Service calls and minor repairs typically run $150–$400. Fixture installations (faucets, toilets, water heaters) generally cost $200–$800 depending on the unit. Larger projects — repipes, drain line replacement, sewer work — can range from $1,500 to $10,000 or more. Always get at least two written estimates for jobs over $500.
Do I need a permit for plumbing work in Indiana?
Most plumbing work beyond basic repairs requires a permit. Indiana state code requires permits for new plumbing installations, additions to existing systems, water heater replacements (in most jurisdictions), and sewer line work. Your licensed plumber typically pulls the permit on your behalf. Unpermitted work can create problems at resale and may void insurance claims.
What is the difference between a plumber and a plumbing contractor?
In Indiana, a Plumbing Contractor is the IPLA-licensed entity legally authorized to contract for and supervise plumbing work. Individual journeymen or apprentices may perform the physical work under the contractor's license and supervision. When hiring for a job, you should contract with and verify the license of the Plumbing Contractor — not just the individual who shows up.
What plumbing work can a homeowner do themselves in Indiana?
Indiana allows homeowners to perform minor repairs on their own property without a license — such as replacing faucets, unclogging drains, or swapping fixtures. However, any work that involves cutting into supply lines, replacing main shutoffs, or altering drain/waste/vent systems typically requires a permit and a licensed contractor. When in doubt, call your local building department.
How long does a plumbing project typically take?
Minor repairs and fixture replacements are usually completed in a few hours. Water heater replacement takes 2–4 hours. Larger jobs like sewer line replacement can take 1–3 days. Whole-home repipes for older houses may take 3–5 days. Timeline depends heavily on accessibility, permit processing time, and job complexity.
What should I ask before hiring a plumber?
Before hiring, ask for: (1) their IPLA license number so you can verify it at mylicense.in.gov, (2) proof of liability insurance and workers' compensation coverage, (3) a written estimate with itemized labor and materials, (4) whether they will pull the necessary permits, and (5) their warranty terms on parts and labor. A reputable licensed plumber will provide all of this without hesitation.
What is an emergency plumber and when do I need one?
An emergency plumber handles urgent situations that can't wait for a scheduled appointment — burst pipes, sewage backups, gas line leaks (in combination with a gas company), or loss of water service. Emergency rates are higher than standard rates (often 1.5–2x). For true emergencies, shut off the main water supply first, then call a licensed plumber. Verify the license even in an emergency — the IPLA portal takes under a minute.
Can a plumber also do gas line work in Indiana?
Licensed plumbing contractors in Indiana are authorized to work on gas piping systems in addition to water and drain systems. This includes running gas lines for appliances, fixing gas leaks, and installing gas shutoffs. For gas emergencies, call your gas utility first to shut off the supply, then hire a licensed plumber or gas fitter for repairs.
