Master Plumber

TR Construction Group, LLC is seeking an experienced WSSC-licensed master plumber to help lead field operations — performing and overseeing complex residential work, pulling permits, supervising journeymen and apprentices, and upholding quality and code compliance. The owner is the company’s WSSC master plumber of record; this master hire expands the company’s permitting and supervisory capacity rather than serving as the license of record.

• Perform and supervise the full range of residential plumbing installation, service, and repair work, including sewer and drain cleaning.
• Pull permits and serve as a licensed authority responsible for code compliance and inspection sign-off.
• Direct and mentor journeymen and apprentices; verify and document apprentice training hours.
• Handle complex diagnostics, repipes, system replacements, and gas work.
• Review estimates, scopes, and completed work for quality and profitability.
• Ensure all work complies with the WSSC plumbing code, gas-fitting requirements, and OSHA standards.
• Support hiring, training, and crew scheduling.
• Maintain professional customer relationships and resolve escalated issues.

Required Qualifications:

• Valid WSSC Master Plumber license: meet WSSC’s journeyman-experience requirements and pass the WSSC Master Plumber examination (administered by PSI). Reciprocity is available from the Maryland State Board, Baltimore County, or Virginia master licensure.
• Extensive residential plumbing and gas-fitting experience.
• Thorough command of the WSSC plumbing code, permitting, and inspection processes.
• Proven ability to lead crews and manage multiple jobs.
• Valid driver’s license and clean driving record.
• Note: company licensure and insurance are maintained by the owner as the WSSC master of record; this hire is not required to carry them personally unless they become a qualifying party in the future.
