The Three Phases, Handled

Groundwork: under-slab drains and supply sleeves before concrete. Rough-in: all supply and DWV piping in the walls, test-pressurized and inspected before drywall. Finish: fixtures, appliances, water heater, and final inspection. We coordinate with your GC's schedule so plumbing is never the trade holding up the build.

ADUs and Additions

Pierce County's ADU wave is real, and ADU plumbing has its own puzzle: tying into existing supply and sewer, sizing for the added demand, and sometimes an ejector pump if the ADU sits below the main line's grade. We plumb ADUs and additions as complete projects — design input included, from your plans.

Why a Small Shop for a Build

The same plumber sees your project from trench to trim. No crew roulette, no rediscovering the plan at every phase, and the person who laid the groundwork is the one setting your fixtures. On a build, that continuity shows up in the details — and in how few callbacks there are.

For Builders & GCs

Straight talk on how we work with builders: full waste and water scope (DWV and supply, ground through trim), bids turned around fast from your plans, and phase scheduling you can actually put on the board — when we commit to a rough-in date, the trade after us starts on time. We're honest about capacity too: we're built for custom homes, ADUs, additions, and builders running a few starts at a time — not 40-lot production tracts. What you get in exchange for that size is the owner on your job at every phase, clean inspections, and a phone that gets answered. If that's the kind of plumbing partner your schedule needs, let's talk.

Common Questions

New Construction Plumbing Questions

Do you work from plans or design the plumbing layout?

Both — we bid from your plans, and we'll flag layout issues early (venting, fixture grouping, water heater placement) while changes are still cheap lines on paper.

Do you handle the permits and inspections?

Yes — plumbing permits, test setups, and inspection scheduling for every phase are part of the job.

Can you plumb just the ADU while another plumber did the main house?

Absolutely. ADU tie-ins to existing systems are their own specialty and we're comfortable coming in for just that scope.

PEX or copper for new construction?

We typically run PEX (Uponor expansion systems) for supply in new residential work — flexibility, freeze tolerance, and fewer fittings in walls — with copper stub-outs where it makes sense. We'll walk you through the why on your specific build.

How early should we get you involved?

Before the foundation pour, ideally at plan stage — groundwork is the first plumbing phase and the hardest to change later.

I'm a builder — how fast can you bid from plans?

Send the plans and we'll give you a real number and a realistic phase schedule quickly — we know builder timelines don't wait. We're sized for custom homes and small builders, and we say so up front rather than overcommitting and slipping your schedule.
