New Home Construction Plumbing Consulting

Your house is plumbed once. Make it count.

Quick answerA new-construction plumbing consultant reviews the plans, sizes the water service, hot water and drainage, levels plumbing bids and inspects the work at the key phases (under-slab, top-out and final) on the owner's behalf. It's most valuable on custom homes and owner-builder projects where nobody else is watching the plumbing closely.
Plan review in 5–7 business days; inspections scheduled to your build $1,500–$6,500 per custom home Independent · no installs

City inspectors check that work meets minimum code. They don't check whether your hot water reaches the primary shower in under a minute, whether the water heater is big enough for the soaking tub, whether the plumber used the PEX you paid for, or whether the under-slab drain was pressure-tested before the concrete went in. Once the slab is poured, those decisions are permanent.

We work for the owner. We review the plans before bidding, size the system for how you'll actually live, write the plumbing spec, compare bids, and visit at the moments that matter most so problems are caught when they're cheap. Builders get a clear spec; you get a house plumbed the way it was promised.

New Construction FAQ

When should I bring you in?

Before plumbing bids go out. The cheapest time to fix a plumbing design issue is on paper; the second cheapest is before the slab is poured.

Will my builder mind?

Good builders appreciate a clear spec and fewer change orders. We keep the communication professional and focused on the plumbing, not on second-guessing the whole project.

Do you design the full plumbing system?

We provide sizing, specifications and plan comments for residential projects. Where a jurisdiction requires sealed engineering drawings, we coordinate with the engineer of record.
