Whole-home repipe in PEX-A or copper to replace failing galvanized, polybutylene, or pinhole-prone copper. Permits handled, walls patched, and everything pressure-tested and inspected.
Repiping is one part of our plumbing installation coverage in Montana. For the full picture — symptoms, costs, and when to repair vs. replace — start with the complete Plumbing Installation guide, or browse every plumbing installation service we offer.
A whole-home repipe is the permanent fix for a house whose supply pipes have reached end-of-life — original galvanized steel closing up and rusting the water, polybutylene from the 1980s–90s failing without warning at the fittings, or copper that keeps developing pinhole leaks on run after run. Instead of chasing one leak at a time inside the walls, a repipe replaces the entire supply distribution in one planned project, restores full pressure to every fixture, and resets the clock on the most failure-prone system in the house.
We repipe in PEX-A and type-L copper. PEX-A is flexible, freeze-tolerant, corrosion-proof, and fast to route with fewer fittings inside the walls, which means fewer potential leak points and a lower cost; type-L copper is rigid, time-proven, and preferred where exposed runs, high heat, or local code call for it. Our plumbers map the runs, open the minimum number of access points, pull the new lines, tie in every fixture, and pressure-test the whole system before anything is closed.
Repiping is turn-key: free on-site consultation, a written quote good for 30 days, permits pulled and the municipal inspection scheduled, drywall access points patched and textured, and the water restored the same day in most single-story homes. Financing is available through Synchrony at 0% APR for the first 12 months on projects over $1,500, and the work carries a 10-year workmanship guarantee on top of the pipe manufacturer's warranty.
Signs you need repiping
Rusty or discolored water
Brown water at the first draw, or a metallic taste, means galvanized pipe is corroding from the inside. When it's happening at multiple fixtures, the whole distribution is due.
Repeated pinhole leaks
A copper system that leaks a pinhole, gets patched, then leaks another one on a different run within months has aggressive water eating it everywhere. Patching becomes a losing game — a repipe ends it.
When every fixture runs weak, not just one, the supply pipe has narrowed from the inside across the whole home. New full-bore pipe restores the pressure the fixtures were designed for.
Polybutylene pipe anywhere in the home
Gray polybutylene supply pipe becomes brittle and fails at the fittings unpredictably. Insurers often won't cover it, and a proactive repipe removes the liability before it lets go.
Home built before 1975
Homes from before the mid-1970s often still run original galvanized steel well past its 50-year life. If it's never been repiped, the pipe is living on borrowed time.
Common causes & what we fix
Galvanized steel at end-of-life
Galvanized pipe corrodes and closes from the inside over decades until flow drops and the water rusts. There's no reversing it — the material has simply reached the end of its service life.
Polybutylene brittleness
Poly pipe and its acetal fittings degrade with exposure to chlorinated water and become brittle, failing at the joints without warning. Whole-home replacement is the only reliable fix.
Aggressive-water copper pitting
Acidic or high-velocity water pits copper from the inside until pinholes weep through, clustering on hot and recirculation lines. When it recurs across runs, the system is the problem.
Hard-water and coastal corrosion
Mineral scale narrows pipe from the inside while coastal salt air corrodes it from the outside, and both accelerate a supply system toward whole-home failure.
Undersized original distribution
Homes plumbed with undersized trunk lines never delivered proper pressure to simultaneous fixtures. A repipe is the chance to correct the sizing, not just replace the pipe.

Frequently asked about repiping
Top questions homeowners searching for Repiping near me ask us:
How long does a repipe take?
A typical single-story home is repiped in 2–3 days: one day to run and tie in the new lines and pass pressure test, and the patching and inspection following. Two-story and larger homes run 3–5 days. Water is usually restored each evening.
What's the project day like?
We lay protection, open the minimum access points, route the new PEX or copper, connect every fixture, pressure-test the system, and schedule the inspection. Then we patch and texture the access holes so the walls look right again. Most homeowners stay in the home throughout.
PEX or copper — which should I choose?
PEX-A is lower cost, freeze-tolerant, corrosion-proof, and has fewer in-wall joints; copper is rigid, proven, and preferred for exposed runs and specific code situations. Most whole-home repipes today use PEX-A, but we'll price both.
Do you handle permits and patching?
Yes — we pull the permit, schedule the municipal inspection, and patch and texture every access point we open. Final paint is typically the homeowner's, and we leave the walls ready for it.
What financing is available?
Synchrony 0% APR for 12 months on qualifying projects. Longer terms at low fixed rates are also available. Fast approval, no prepayment penalty, and it can cover a water heater or softener added in the same project.
