Maurice serves as President and brings 50+ years of personal plumbing-industry experience into the operation.

Reference Notes
Hawaii plumbing licensing runs through the Department of Commerce and Consumer Affairs (DCCA) Professional and Vocational Licensing Division. DCCA issues Plumbing Contractor (CT-) credentials through sequentially numbered records. Verification runs through cca.hawaii.gov. The City and County of Honolulu Department of Planning and Permitting issues building permits within Oahu. The Honolulu Board of Water Supply handles water-and-sewer service connections plus annual backflow-prevention testing across Oahu. Hawaii’s island-and-isolated-supply-chain context plus saltwater-corrosion exposure plus volcanic-soil substrate plus tropical-climate humidity all shape recurring service categories.
Honolulu-area residential housing reflects Hawaii’s 19th-and-20th-century development pattern. Pre-1900 housing remains in the Honolulu downtown historic core plus Chinatown. Single-wall construction housing built 1900-1940 dominates the older residential neighborhoods (Kaimuki, Kapahulu, Manoa, Nuuanu, Kalihi). Postwar tract construction built out Aiea, Pearl City, Kaneohe, and the Windward side through 1945-1975. The 1980s-1990s drove the Mililani master-planned-community expansion plus Hawaii Kai. Kapolei and Ewa Beach extended outer-Oahu growth through the 2000s. Tropical climate plus saltwater-corrosion exposure plus single-wall-construction prevalence plus high water-import dependency shape recurring service categories: cast-iron drain replacement in pre-1950 stock, copper-pipe corrosion repair, sewer-line work under high-water-table conditions, and post-storm restoration plumbing.
The four firms profiled cover four positions on the Honolulu market arc. Sen Plex Corporation leads tenure with Francis Sen’s 1945 founding (originally Oahu Plumbing and Sheet Metal) plus 81 years of three-generation Sen family operation under contemporary statewide operations across Oahu, Maui, Kauai, and Hawaii Island. Creative Plumbing follows with 50 years of family-owned Oahu operation since 1976. Allens Plumbing brings 44 years of Steve Allen family operation since the 1981 incorporation as Allens Plumbing Inc., The Drain Surgeon, plus a bi-island Oahu-and-Maui operational structure. M. Torigoe Plumbing runs 41 years of Maurice F. Torigoe’s locally-owned operation since the 1985 founding (50+ years cumulative trade career; Hawaii License #CT-17750).
Verification paths run through cca.hawaii.gov, BBB Hawaii listings, the PHCC of Hawaii directory, and the City and County of Honolulu Department of Planning and Permitting contractor records. Pre-1950 single-wall-construction Kaimuki, Manoa, and Nuuanu housing tilts toward Sen Plex’s 81-year three-generation depth. Family-owned Oahu residential service fits Creative Plumbing. Bi-island Oahu-and-Maui service plus BBB A+ rating fits Allens. Locally-owned Maurice Torigoe 50+ year career plus License #CT-17750 fits M. Torigoe Plumbing.
Selection Methodology
Selection follows four criteria. First, continuous family ownership or founder-operator continuity outside the national rollup pattern. Second, verifiable Hawaii Plumbing Contractor (CT-) license cross-checked via the Department of Commerce and Consumer Affairs Professional and Vocational Licensing Division public lookup. Third, BBB Accreditation or equivalent third-party rating. Fourth, minimum 10-year continuous operating tenure with documented Honolulu service coverage. Firms acquired by national franchise networks (Authority Brands’ Benjamin Franklin Plumbing, Neighborly’s Mr. Rooter, Service Experts, Roto-Rooter, Wrench Group, Redwood Services, Master Trades Group, ARS) are excluded.
Frequently Asked Questions
How do I verify a Honolulu plumber’s license?
Use the Hawaii Department of Commerce and Consumer Affairs (DCCA) Professional and Vocational Licensing Division public licensee database at cca.hawaii.gov. Search by license number or business name. Confirm active status, classification, bonding, and insurance before authorizing work.
What credentials should a Honolulu plumber hold?
At minimum: Hawaii Plumbing Contractor (CT-) credential plus general liability insurance and workers’ compensation coverage. Specialty work (gas line, backflow prevention, fire sprinkler, sewer lateral) requires additional credential layers.
How can I tell if a Honolulu plumber is locally owned versus a national rollup?
Check ownership disclosures and acquisition history. National franchise brands typically operate under parent-company branding. Search the firm name plus “acquired” or “parent company” to surface ownership structure. The four firms in this directory all run as independent locally-owned operators.
When should I call an emergency plumber in Honolulu?
Burst pipes, sewer backups, gas leaks, no-water events, and water heater failures justify after-hours dispatch. Tropical-storm and hurricane-flood events drive substantial post-storm emergency demand across Oahu. Each firm in this directory offers either 24/7 emergency service or structured after-hours response.
