Know the signs

What builders get.

What builders tell us matters most: showing up when we said we would, and being reachable when something changes.

A foreman on every crew

One point of contact who runs the crew, the materials and the punch list, and reports to our superintendent.

Your schedule, not ours

We work to the construction schedule and call early when a trade ahead of us slips.

Production and custom

Repeatable quality across many lots for production work, close coordination with the owner and designer for custom work.

Warranty calls handled

Warranty calls on the homes we plumb come to us, and our own plumbers take care of them.

Questions

New home plumbing, answered.

Answers from licensed plumbers. Still unsure? Call (509) 535-5946, 24 hours a day.

How do I request a bid for a new home or subdivision?

Send plans, specifications, the schedule and the fixture package through our bid request page. The more complete the package, the faster and more accurate the bid. For a repair in an existing home, use Get a quote instead; it goes to a different team.

What are the phases of new construction plumbing?

Three: underground, with waste and supply below the slab or in the crawl space before concrete; rough-in, with supply and drain lines in the framed walls before insulation and drywall; and trim-out, with fixtures, faucets, the water heater and final connections. Each has its own inspection.

Who pulls the plumbing permits on new construction?

We do. The plumbing contractor pulls the plumbing permits and schedules each inspection, while the building permit stays with the builder or owner. We confirm the split in writing at contract so nothing falls between parties.

When should a builder bring the plumber in?

At the plan stage. Reviewing plans before the slab or foundation goes in catches conflicts between plumbing runs, structure and mechanical while changes are still cheap; after framing, everyone works around decisions already made.

Do you plumb new homes in North Idaho?

Yes. Our plumbers are licensed in Washington and Idaho, and our construction crews work across Spokane and North Idaho, including Coeur d’Alene, Post Falls, Hayden and Sandpoint.
