Splices & Corrosion

Waterproof Wire Connectors & Splices

Most landscape lighting “mystery failures” are corrosion failures. Waterproof splice discipline is one of the highest-ROI reliability upgrades.

Fewer flickers Cleaner diagnostics Longer lamp life Serviceable repairs

Why splices fail

  • Water intrusion: moisture enters and creates corrosion over time.
  • Poor connections: loose conductors create resistance and heat.
  • Buried \"dry\" wire nuts: standard connectors aren't designed for long-term burial in wet soil.

We typically rebuild buried splices using waterproof connector systems (brands like King Innovation are commonly used in the electrical and irrigation industries) and then verify voltage under load.

What we do during repair visits

  • Locate failure points: identify corroded splices and damaged cable sections.
  • Rebuild for reliability: replace connections using waterproof/gel protection and clean conductor prep.
  • Confirm system behavior: re-check voltage and lighting uniformity at night.
