Ground-up plumbing for new home builds — from rough-in to final trim throughout Portland metro.
Building a new home or commercial property in the Portland area? Getting the plumbing right from day one is critical — and it requires a licensed plumber who shows up on schedule, works cleanly with your framing crew, and passes inspections the first time.
PNW Plumbing LLC provides complete new construction plumbing for custom homes, spec homes, ADUs, and light commercial projects throughout Portland, Oregon and surrounding areas. We work with builders and general contractors who expect professionalism, accuracy, and zero delays.
If you recognize any of these, call PNW Plumbing at 503-957-8703.
Sewer, water, and gas lines stubbed before the slab is poured — critical to get right the first time.
All drain, waste, vent, and supply piping run through framing, coordinated with other trades, and inspected.
Vents extended through roof, all pipes stubbed out and capped, ready for insulation and drywall.
Final phase: all fixtures installed, connected, and tested — toilets, faucets, water heater, and appliances.
We handle all permit applications and schedule each required inspection so your build stays on timeline.
We communicate directly with your GC and other trades to prevent conflicts and keep the project moving.
Every job follows the same straightforward process — no surprises.
We review architectural and mechanical plans, identify any code issues upfront, and submit for permits before breaking ground.
