How to Hire a Licensed Plumber in Indiana

March 7, 2026

Why Licensing Matters

Indiana requires all plumbing work to be performed by or under the direct supervision of an IPLA-licensed Plumbing Contractor. The license signals that the contractor has passed a state exam, met education requirements, and is accountable to the Indiana Professional Licensing Agency.

Hiring an unlicensed plumber creates real risk: failed inspections, voided homeowner’s insurance claims, no recourse through the IPLA if work is defective, and potential code violations that surface at sale.

Step 1: Verify the License Before Hiring

Every licensed Indiana plumbing contractor has a license number beginning with PC. You can verify any license in under a minute at the Indiana Professional Licensing Agency verification portal.

Search by name or license number. Confirm:

• Status is Active (not Expired or Inactive)
• The name matches the contractor you’re speaking with
• The license type is Plumbing Contractor

Every profile on this site shows the verified IPLA license number. Use it.

Step 2: Confirm Insurance Coverage

A licensed plumber should carry two types of insurance:

• General liability — covers damage to your property during the job
• Workers’ compensation — covers injuries to workers on your property

Ask for a certificate of insurance before work begins. If they can’t produce one, move on. If a worker is injured on your property and the contractor has no workers’ comp, you could be liable.

Step 3: Get a Written Estimate

For any job over a few hundred dollars, get a written estimate with:

• Itemized labor and materials (not a single lump sum)
• The scope of work described specifically
• Payment terms (avoid paying more than 10–30% upfront for larger jobs)
• Estimated completion timeline

Get at least two estimates for jobs over $1,000. Prices vary significantly between contractors, and an unusually low bid may indicate cut-rate materials or unlicensed labor.

Step 4: Ask About Permits

Most plumbing work beyond basic repairs requires a permit in Indiana. Your licensed contractor should pull the permit on your behalf — if a contractor tells you permits aren’t necessary for a job that clearly requires one, that’s a red flag.

Unpermitted plumbing work:

• Can fail inspection if discovered later
• May void homeowner’s insurance claims
• Creates liability issues when you sell the home

Step 5: Clarify Warranty Terms

Ask what warranty the contractor offers on their work and the parts they install. Reputable contractors stand behind their work. Get warranty terms in writing.

Manufacturer warranties on water heaters, fixtures, and other equipment are separate from the contractor’s labor warranty.

Red Flags to Avoid

• No license number — or a number that doesn’t verify at IPLA
• Cash-only payment — no paper trail protects the contractor, not you
• No written estimate — “I’ll know when I’m done” is not acceptable for major work
• Pressure to skip permits — protects no one but the contractor
• No insurance documentation — you absorb all the risk
