How the job goes
No runaround and no mystery — here's how we run the work from first call to finished job.
01
Evaluate the site
Soil, slope, setbacks from wells and property lines, and the county's requirements all shape the design. Our plumber evaluates your site and handles the groundwork for permitting.
02
Design and quote
The system gets sized to your home — bedrooms, fixtures, actual use — and you get a written estimate for the complete job before a shovel hits the dirt.
03
Install to code
Tank set below frost depth, lines pitched right, drain field laid to spec and inspected — the details that decide whether a septic system lasts decades or fails in five years.
04
Backfill and handoff
Once inspected and passed, everything is backfilled and graded, and our plumber walks you through where things are, what to keep off the drain field, and how to keep the system healthy.

(406) 606-9682- How much does a septic system cost?
- It depends on your soil, the size of your home, and the type of system your site needs — a straightforward gravity system is a very different job than an engineered one. Our plumber evaluates your property and gives you a free written estimate for your actual site, not a generic number.
- How do I know if my septic system is failing?
- Slow drains throughout the house, sewage odors in the yard, soggy or unusually green patches over the drain field, or backups after heavy use are the classic signs. Caught early, some problems are repairable — wait too long and you're replacing the drain field. If something seems off, have it looked at.
- Can a septic system freeze in a Montana winter?
- It can — usually when a tank or line is set too shallow, a drip leak keeps a line half-full, or snow cover gets compacted over the system. Proper depth and pitch at installation prevents most of it. If yours has frozen before, our plumber can find the cause and fix it for good instead of thawing it every February.
- What can spring runoff do to a septic system?
- Saturated ground during spring melt is the hardest season on a drain field — the soil can't absorb effluent when it's already waterlogged. Systems built with the right depth and location handle it; marginal ones back up every spring. Going easy on water use during the worst melt weeks helps too.
- How long does a septic installation take?
- Once permits are in hand, most residential installations take a few days of site work, plus the inspection before backfill. Weather and soil conditions can move that around — our plumber gives you a realistic schedule with your estimate and keeps you posted as the job runs.
