Why verification matters
Unlicensed plumbing is a leading cause of hidden water damage and failed inspections. A licensed plumber is bonded, insured, and works to code - so a repair does not become a mold claim.

The state board's job ends at the license. Ours starts there.
When you need a licensed plumber in a market you don't know, you end up with a dozen browser tabs open to state websites and no phone numbers to show for it — typically 2 to 4 hours of work. ContractorRoster delivers the complete list in minutes: every active license in your area, enriched with phone, email, and website for over 95% of records.
Ohio: Ohio's OCILB licenses electrical, plumbing, HVAC, hydronics, and refrigeration contractors at the state level. General contractors, roofers, and landscapers are licensed by individual cities and counties — no statewide roster exists for those trades.
