Plumbing Repair Listings

The listings catalogued here represent licensed plumbing repair contractors operating across the United States, organized by service category, geographic coverage, and licensing classification. Each entry reflects verified professional standing within state-regulated frameworks, covering residential, commercial, and specialty plumbing repair sectors. The Directory Purpose and Scope establishes the eligibility standards governing which providers appear in this index.

What each listing covers

Each listing in this directory corresponds to a single licensed plumbing repair business or sole proprietor holding an active contractor or journeyman license issued by a state plumbing board or equivalent regulatory authority. The United States has no single federal plumbing licensing body — licensing authority is distributed across 50 state jurisdictions, with the contractor classification thresholds, examination requirements, and continuing education mandates varying by state.

Listings are structured around 4 primary service classifications:

1. Residential repair — single-family and multifamily dwellings up to 3 stories, governed by state adoptions of the Uniform Plumbing Code (UPC) published by the International Association of Plumbing and Mechanical Officials (IAPMO) or the International Plumbing Code (IPC) published by the International Code Council (ICC)
2. Commercial repair — office, retail, institutional, and industrial facilities, which carry separate licensing tiers in states including California, Texas, and Florida
3. Emergency and 24-hour service — unscheduled urgent repair covering burst pipes, active leaks, and sewer backups; distinct from routine maintenance contracts
4. Specialty systems — gas piping, hydronic heating, backflow prevention, and cross-connection control; these subsets require additional certifications in most jurisdictions, such as the ASSE 5110 backflow certification standard published by the American Society of Sanitary Engineering (ASSE)

Listings do not represent endorsements, ratings, or ranked recommendations. The directory describes the service landscape as a structured reference, consistent with the framework detailed on the How to Use This Plumbing Repair Resource page.

Geographic distribution

Listings are distributed nationally across all 50 states and the District of Columbia. Concentration is highest in the 10 most populous states — California, Texas, Florida, New York, Pennsylvania, Illinois, Ohio, Georgia, North Carolina, and Michigan — where licensed contractor populations are largest and plumbing board enforcement infrastructure is most developed.

State-level regulatory bodies that govern contractors appearing in this directory include agencies such as the California Contractors State License Board (CSLB), the Texas State Board of Plumbing Examiners (TSBPE), and the Florida Department of Business and Professional Regulation (DBPR). Each state board maintains its own public license verification portal, which serves as the primary authoritative source for confirming a listed contractor's current standing.

Rural coverage varies significantly. States with lower population density — including Wyoming, North Dakota, and Vermont — have smaller licensed contractor pools, and listings in those areas may reflect broader geographic service radii of 75 miles or more from a contractor's registered business address.

How to read an entry

Each directory entry is structured with discrete data fields to allow consistent comparison across providers. A standard entry contains the following components:

1. Business name — the legal or DBA (doing business as) name as registered with the relevant state board
2. License number and class — the state-issued license identifier and classification (e.g., Master Plumber, Journeyman, Contractor), linked where possible to the issuing board's public verification database
3. Service classification — one or more of the 4 primary categories listed above, plus any specialty endorsements
4. Geographic coverage — county-level or metro-area service territory as declared by the contractor
5. Permit-pulling authority — indicates whether the licensee holds contractor-class credentials permitting them to pull permits independently; journeyman-only licensees in states such as Oregon and Washington are required to work under a licensed contractor of record for permitted work
6. Inspection coordination — flags whether the contractor's scope includes post-repair inspection scheduling with the applicable local Authority Having Jurisdiction (AHJ)

Permit and inspection requirements embedded in entries reflect state plumbing code mandates. Under both the UPC and IPC frameworks, repair work involving alterations to drain-waste-vent (DWV) systems, supply line replacements, or fixture additions typically triggers a permit requirement enforced by the local AHJ, not the state board.

What listings include and exclude

Included:

• Contractors holding active state plumbing licenses at the journeyman or master/contractor level
• Businesses registered to operate in at least 1 US state with a plumbing-specific or mechanical contractor license covering plumbing repair scope
• Specialty providers holding certifications from named bodies (ASSE, IAPMO, ICC) where those certifications define the legal scope of work in the relevant jurisdiction

Excluded:

• Unlicensed handyman services performing plumbing tasks, regardless of experience or market presence
• HVAC and mechanical contractors whose license scope does not explicitly cover residential or commercial plumbing repair
• Providers whose state license is listed as expired, suspended, or revoked on the issuing board's public verification database
• General contractors who subcontract all plumbing work and hold no direct plumbing licensure

Sewer-specific repair providers — including those performing trenchless relining, pipe bursting, and lateral replacement — are catalogued separately at Sewer Repair Authority, which covers the distinct licensing requirements and inspection protocols that apply to below-grade sewer infrastructure. Pump repair specialists, including well pump and booster pump contractors, fall under the scope maintained at Pump Repair Authority.

Cross-referencing between directory verticals is documented in the Plumbing Repair Listings index, which maintains the master taxonomy linking service classifications across all plumbing repair provider categories tracked within this network.
