Sprinkler Repair
Dry patches, geysers & zones that won't fire
Most irrigation problems announce themselves in the lawn before you ever look at the equipment. A dry crescent at the edge of a zone usually means a head is misaligned, clogged, or sunk below grade. A permanently soggy patch means a leak downstream of a valve. A zone that will not start at all is usually electrical — a solenoid or a wire splice — rather than the controller everyone blames first.
We diagnose the system rather than replacing parts until the symptom goes away. That means running each zone, checking coverage and pressure, testing solenoids and wiring where a zone is dead, and locating leaks before we start digging. You get told what is actually wrong, what it will take to fix, and what can reasonably wait until next season.
We repair systems we did not install, including older systems with mixed or discontinued parts. If a component is no longer made, we will tell you honestly whether a compatible retrofit or a partial rebuild is the better long-term call.
Tell us what your system is doing and we'll diagnose it.

Sprinkler Repair questions
Common questions about our sprinkler repair in Missoula and the Bitterroot Valley.
The reliable signs are visible in the landscape: dry patches or brown arcs in an otherwise healthy lawn, soggy ground or standing water that never dries, heads that mist rather than throw a solid stream, a zone that never runs, a zone that never stops, or a water bill that climbs without any change in your schedule. Any one of those is worth a look.
Rarely. Controllers do fail, but far more often a dead zone traces back to the solenoid on that zone's valve or to a wire splice that has corroded underground. That is why we test at the valve rather than replacing the controller first — it is a much cheaper fix when the diagnosis is right.
Yes, and most of our repair work is exactly that. Older systems in this area often mix brands and generations of parts. Where something is discontinued we will tell you whether a compatible replacement exists or whether rebuilding that section makes more sense than chasing obsolete components.
That combination usually points to a leak on the pressurised side of the system — a cracked lateral, a failed valve seal, or a mainline leak — where water is escaping underground instead of reaching the heads. It can also be a valve not closing fully, which lets a zone weep continuously. Both are worth diagnosing quickly, because the water is being billed either way.
That is the goal. We isolate zone by zone to narrow the location before any excavation, so the dig is targeted rather than exploratory. Some leaks are genuinely hard to pin down, and we will be straight with you if a repair is likely to need more exposure than usual.
