Expert Plumber Services in Missoula, Montana

Pipes in unheated crawlspaces, attached garages, and along exterior walls take the worst of a Missoula January. When the mercury sits in the teens for days, water in an exposed line turns solid and the pressure spike splits the pipe — often at a fitting. We cut out the damaged section and replace it with properly sized pipe. Then we add the missing protection: insulation, an interior shutoff for the hose bibb, or a reroute away from the cold wall. Getting ahead of it in the fall means exposed runs get insulated or rerouted before January tests them.

Missoula's water comes from the Missoula Valley Aquifer, and regional estimates put its hardness around 111 mg/L as CaCO₃ — moderately hard. That mineral load settles out as scale on water heater elements, inside tankless exchangers, and on fixture aerators. Over years it also coats the inside of supply lines, narrowing them and dragging water pressure down. We descale water heaters, replace scaled-out fixtures, and test whether a given home is a candidate for softening. Regular flushing keeps a new water heater from aging early.

Many of the valley's pre-1980 homes still run on galvanized steel supply lines, especially in the lower Rattlesnake and around the University District. Galvanized pipe corrodes from the inside, so a line that looks fine from the basement can be choked to a pencil-width channel within. The first signs are weak pressure at fixtures far from the meter and water that runs rusty after the line sits overnight. When repairs turn into a pattern, we repipe in sections or whole-house with copper or PEX, matched to the home's layout and budget.

Older Missoula homes often carry cast-iron drain and sewer lines, and age treats them roughly. Scale builds on the rough interior until the pipe grabs grease and paper, and the line itself can crack or sag into a belly that holds standing water. A camera inspection shows exactly where the damage is instead of guessing. Depending on what we see, we clear and descale, spot-repair a bad section, or replace a lateral that has run out of life.

Tree roots go where the water is, and in the valley's older neighborhoods with big mature trees, that means sewer laterals. Roots slip through joints and tiny cracks, then spread into a mat that catches paper and slows the whole drain system. The classic sign is a main-drain backup that returns a few months after a clearing. We jet the line clean with hydro jetting equipment, then camera it. The fix targets the actual breach — often a cracked section or offset joint — instead of just clearing the symptom.

Outdoor faucets take more abuse in Missoula than almost any other fixture. A standard hose bibb left charged through January can split inside the wall, and the leak shows up as a soaked sill plate come spring. We replace vulnerable spigots with frost-proof models that shut off deep inside the warm envelope, add interior shutoffs with drains, and winterize irrigation systems before the cold arrives. If a bibb already split, we open the wall carefully, repair the line, and set the new bibb up so the next winter cannot reach it.

Weak pressure is rarely just weak pressure. In Missoula it usually traces to scale from the moderately hard aquifer water, a galvanized line closing from the inside, or a pressure regulator past its working years. We track the drop by comparing readings at the meter with readings at the fixtures. The fix depends on the cause: descaling, targeted repiping, a new regulator, or work on the main water line when that is the bottleneck.
