How the job goes
No runaround and no mystery — here's how we run the work from first call to finished job.
01
Scope it on site
Our plumber meets you at your building, looks at the actual conditions — not just the drawings — and gives you a written estimate with a realistic schedule built around your hours of operation.
02
Plan around your business
Work is sequenced so you stay open wherever possible: after-hours tie-ins, one restroom down at a time, water shutoffs scheduled and announced in advance.
03
Code-compliant install
ADA clearances, tempered water, backflow protection, grease interceptor sizing — the details inspectors check are built in from the start, not patched in after a failed inspection.
04
Inspection & handoff
Our plumber meets the inspector, walks you through the finished work, and leaves you with a system your staff can operate — backed by a one-year warranty.
Good to know
Commercial 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- Can you do the work without closing my business?
- In most cases, yes. Our plumber schedules tie-ins and shutoffs after hours or during your slow windows, and sequences the work so restrooms and kitchens stay usable as long as possible. Tell him your hours and he'll build the plan around them.
- What does a commercial plumbing project cost?
- It comes down to scope — an ADA restroom upgrade is a very different job than a full restaurant build-out. Our plumber walks your space, scopes it in writing, and gives you a firm picture of cost and schedule before work starts. The estimate is free.
- Do you handle ADA restroom compliance?
- Yes. Fixture heights, clearances, grab bars, tempered water, accessible drinking fountains — our plumber builds ADA requirements into the design so you pass inspection and your customers are taken care of.
- Do you install and service grease traps?
- Yes — grease interceptors sized to your kitchen and installed to code, plus repairs and re-pipes on existing traps that aren't keeping up. If the health inspector flagged it, call and it gets fixed properly.
- My building's pipes freeze every winter. Can that be fixed?
- Usually, yes. Commercial buildings around Billings freeze for predictable reasons — lines run through unheated spaces, dead legs near loading docks, missing insulation. Our plumber can trace the problem areas and re-route, insulate, or heat-trace them before the next cold snap does real damage.
