What our customers say
Commercial Plumbing Excellence in Hillsboro
Hillsboro’s growth in manufacturing, warehousing, healthcare, and mixed-use developments places commercial facilities under constant pressure to keep water, waste, and gas lines operating flawlessly. Downtime is expensive, safety is paramount, and any plumbing disruption ripples through entire supply chains and workforces. HEP Company delivers a comprehensive commercial plumbing service portfolio tailored to the unique demands of Hillsboro’s business community. From design-build projects for new construction to proactive maintenance plans for established properties, every task is handled with rigor, transparency, and an unwavering commitment to code compliance.
Why Specialized Commercial Plumbing Matters
Commercial buildings differ from residential structures in pipe sizing, fixture counts, occupancy loads, flow rates, and regulatory scrutiny. Choosing a contractor that understands these differences is essential. HEP’s commercial focus addresses:
- Complex piping networks spanning multiple floors and zones
- High-capacity water heaters, boilers, and recirculation systems
- Grease interceptors, backflow preventers, and cross-connection controls
- Industrial process lines for compressed air, chemicals, or purified water
- Strict adherence to state and municipal plumbing codes
- Coordination with architects, mechanical engineers, and general contractors
Hillsboro’s Regulatory Landscape
The City of Hillsboro enforces Oregon Plumbing Specialty Code requirements alongside environmental standards designed to protect the Tualatin River watershed. HEP Company maintains active relationships with local building officials and inspectors, ensuring every permit, plan review, and inspection proceeds without delay. Detailed submittal packages, stamped drawings, and fixture cut sheets reduce administrative friction and shorten project timelines.
