What Jack B Harper Contractor LLC does

Jack B. Harper Contractor LLC (operating as JBH Contracting, or JHC) is a privately held Louisiana LLC that installs and repairs traffic attenuators across the southeastern United States. The business was originally a division of Gulf Industries (founded 1963 in Louisiana) and was spun off as a standalone entity in 2009. The company concentrates on three product lines — TMA (Truck Mounted Attenuator) services, temporary attenuators, and permanent attenuators — offered to state and local transportation departments and to infrastructure and construction contractors. Operations are organized around a Covington, Louisiana headquarters and three additional field locations in Metairie, Louisiana; Boynton Beach, Florida; and Sanford, Florida, delivering service coverage across eight southeastern states with stated response times as low as 24 hours.

The commercial model is a field-services quote-based direct sales motion. Customers contact JHC by phone or email ([email protected]) or via a reCAPTCHA-protected web form to request installation or repair. Two revenue streams are disclosed: attenuator installation services and attenuator repair/maintenance services. There is no publicly disclosed pricing, no subscription or recurring managed-service contract, and no technology platform layer — the offering is labor- and equipment-led rather than software-led. Marketing presence is minimal, limited to the company website and an Instagram account; there are no documented partnerships, no patents, no third-party distributors, and no app or API surface.

The company currently employs 31 people. There are no funding rounds, M&A events, awards, regulatory actions, or named logos on file. Owning no subsidiaries and no parent company, JHC is a single-entity operating contractor whose defensibility rests on regional density, multi-decade operational history, and a 24-hour response SLA rather than on technology, data assets, or financial scale.
