Our Irrigation Repair Process
System Assessment
We run each zone of your irrigation system to observe operation, identify all problem areas, and document what needs repair before touching anything.
Diagnosis
We trace issues to their source — whether a broken head, underground leak, clogged nozzle, valve failure, or controller issue — and explain our findings clearly before proceeding.
Quote & Approval
We provide a clear repair quote covering all identified issues. No surprise costs — you approve the scope before work begins.
Sprinkler Head Replacement
Damaged or broken heads are replaced with compatible, high-quality replacements. We ensure the spray pattern, radius, and height match your system's original specifications.
Leak Repair
Underground leaks are located, excavated carefully, and repaired with quality fittings. We restore the disturbed turf or bed area after repairs are complete.
Pressure & Coverage Adjustment
After repairs, we run the system and adjust spray patterns, head height, and pressure to ensure even, efficient coverage across all zones.
Final System Test
We run every zone in your presence and verify complete, even coverage before calling the job done. You can see exactly what was fixed and confirm you're satisfied.

Irrigation System Repair FAQ
Common warning signs include: dry or brown patches in otherwise green lawn areas, unusually wet or muddy spots indicating underground leaks, sprinkler heads that aren't rotating or are spraying sideways, zones that won't activate, water puddling on hard surfaces, or a noticeable increase in your water bill. If you notice any of these, call us for a diagnostic visit at (843) 386-4878.
Yes. We work on all major brands including Rain Bird, Hunter, Toro, Orbit, and Rainbird. We carry a wide range of replacement parts and heads in our truck for most systems. For specialized or older systems, we may need to order specific components, but we'll communicate this clearly upfront.
Our primary irrigation service is repair and adjustment of existing systems. For new irrigation system installation, we can assess your property and provide recommendations. Contact us to discuss your specific needs and we'll advise on the best path forward.
We recommend a full system inspection at least once per year — ideally at the start of the irrigation season in spring. This catches any winter damage, shifted heads, or minor leaks before they become major problems during the summer watering season. A spring inspection also allows for adjustment of zones after any landscaping changes during the off-season.
A sprinkler head that shoots straight up without rotating or deflecting properly typically indicates a broken deflector, worn rotor mechanism, or debris clogging the head. In some cases, the head may have been damaged by a lawn mower. These are straightforward repairs — usually a head replacement. Call us for a quick assessment at (843) 386-4878.
Cost depends on the type and number of repairs needed. Simple sprinkler head replacements are very affordable. Underground pipe repairs are more involved. We always provide a free diagnostic assessment and clear quote before any work begins — no surprise bills. Call (843) 386-4878 to schedule your free estimate.
