Sprinkler Repair Services Throughout Wilmington

Oak and maple roots in Wilmington grow with surprising force. A root doesn't need to be thick to split a PVC lateral — even pencil-diameter feeder roots work their way into glued joints and expand over a few seasons until the fitting cracks. We see this constantly in the older neighborhoods near Town Common and along Glen Road where trees are 50-70 years old. The tell-tale sign is a soggy patch that appears between two heads. EMI Irrigation repairs these breaks by cutting out the damaged section and splicing in flexible poly pipe with barbed couplings that won't re-crack. A typical root-damage repair runs $150-$350 depending on depth and how far the root has displaced the line. We can usually complete the fix in under two hours.

Many post-war Cape Cods and ranches around Silver Lake have irrigation systems cobbled together over decades — one contractor added two zones in 1998, another spliced in drip lines in 2005, and someone's brother-in-law ran a zone off a garden hose bib in 2012. The wiring is a tangle of splices and the valve boxes are buried under mulch. EMI Irrigation starts with a full system audit: we locate every valve, trace every wire, and map every head. From there, we prioritize repairs by severity. A complete diagnostic and repair plan runs $95 for the assessment, and most repairs fall between $200-$600. We document everything so you have a clear system map going forward instead of guessing which wire goes where.
