Two Big Townships, Four Decades of Irrigation
Middletown and Wall are among the largest townships in Monmouth County by area, and the irrigation stock reflects that spread. We work on systems installed in the 1980s alongside systems installed last year, in neighborhoods ranging from dense post-war subdivisions to multi-acre properties on well water.
What that means practically: the failure profile depends heavily on when your system went in and who installed it. A 1990s system with original galvanized components and non-waterproofed splices has entirely different problems than a 2018 install with a smart controller.
What Fails Most Often Here
Dead zones
The most common call. A zone that will not activate is almost always one of four things: a failed solenoid, a corroded or broken wire splice, a bad controller station, or a valve diaphragm that has given up. Rodent damage to wire is more common in the wooded sections of both townships than most homeowners expect. We trace the fault rather than replacing parts until something works.
Broken and clogged heads
Mowers, foot traffic and vehicles are the leading cause of head damage everywhere, and both townships have plenty of lawn. Sand and grit in the water also clog nozzles, particularly on well-fed systems. Replacement heads for all major brands are stocked on the truck.
Underground leaks
The tells are a soggy patch that never dries, a water bill that jumped for no clear reason, or system-wide low pressure. Older PVC laterals in the long-established sections of Middletown crack at fittings as the ground shifts over decades. We locate and repair with minimal digging.
Pressure problems
Wall Township’s mix of municipal supply and private wells produces pressure issues in both directions. Too little and you get dry arcs and dead corners; too much and heads mist instead of throwing, wasting water and burning through seals. Both are correctable.
Backflow preventer issues
Required by New Jersey law. If it is dripping or failing to hold pressure it needs prompt attention — and if it was not properly winterized, spring is when you find out.
Controller and timer faults
Power surges, dead backup batteries, corroded terminal strips. We service Rain Bird, Hunter, Orbit, Rachio and Toro, and can upgrade an aging unit to a smart controller in most cases without touching your wiring or valves.
Repair or Replace?
Under 10 years old: repair, almost always. Fifteen-plus years with multiple failing zones, aging valves and an outdated controller: a phased replacement is often the better five-year math. We give the honest recommendation, not the one that maximizes the invoice.

Commercial, HOA and Condo Associations
Both townships have substantial commercial and association property. We handle multi-zone commercial systems, master valves, booster pumps and large backflow assemblies, and property managers can set up a service agreement for priority, documented service. See commercial irrigation.
Before Fall Gets Here
If a zone has been misbehaving all season, get it repaired before winterization rather than after. A valve that is already failing is far more likely to crack under freeze stress — and a spring repair costs you lawn health during the six weeks when everyone needs a technician at once. See our 2026 winterization schedule.
