How the job goes
No runaround and no mystery — here's how we run the work from first call to finished job.
01
Walk the plans together
Our plumber reviews your blueprints or walks the site with you and your builder, flags anything that'll bite you later — fixture locations, venting, frost depth for water and sewer lines — and gives you a clear written estimate.
02
Underground & rough-in
Drainage and water lines go in below frost line, then the full rough-in: supply, drain-waste-vent, gas, and any radiant heat loops — laid clean, labeled, and pressure-tested before anything gets covered up.
03
Inspections, passed
Our plumber schedules and meets the inspectors himself. Because the work is done to code the first time, inspections don't stall your build schedule.
04
Finish & walkthrough
Once walls are closed, fixtures, water heater, and trim go in. Our plumber walks the finished system with you, shows you shutoffs and maintenance points, and backs it all with a one-year warranty.
Good to know
New Construction questions, answered straight
Still wondering about something? Call or text and you'll reach our plumber directly — the plumber doing the work, not a call center.
(406) 606-9682- When should I bring in a plumber on a new build?
- Before the foundation is poured, ideally. Underground drainage has to go in first, and small decisions at the blueprint stage — where the water heater sits, how bathrooms stack, where gas lines run — save real money later. Get us the plans early and we'll flag issues before they're set in concrete.
- How much does new-construction plumbing cost?
- It depends on the number of bathrooms, fixture choices, and whether you're adding radiant heat, gas lines, or a septic system. Our plumber gives you a written estimate off your plans — a real number for your actual build, not a per-square-foot guess. Estimates are free.
- How long does the plumbing take on a new home?
- Underground work usually takes a few days, rough-in roughly a week for a typical home, and finish work a few days once the walls are closed. The honest answer is that plumbing follows the build schedule — our plumber coordinates directly with your builder so plumbing is never the trade holding things up.
- Do you work with builders and general contractors?
- Yes — builders and GCs around Billings are a big part of the business. Our plumber shows up when scheduled, keeps the work inspection-ready, and communicates directly so there are no surprises on site.
- How deep do water and sewer lines need to be in Montana?
- Below frost line — around Billings that generally means six feet or deeper for water service. It's one of the most important details on a Montana build: lines set too shallow freeze in a hard winter and cost far more to fix than to bury right the first time.
- Can you rough in for things we'll add later?
- Absolutely — that's smart building. A basement bathroom rough-in, a softener loop, a gas stub for a future shop heater or fire pit: adding them during construction costs a fraction of cutting them in after the fact. Tell us what you might want someday and we'll plan for it now.
