Fence Post Rot at Base — Groundwater Indicator

Rotting fence posts in BC can indicate persistently wet soil conditions that also affect foundation drainage.

Possible Causes

  • Poor drainage keeping soil saturated around fence posts
  • Underground water leak saturating specific areas
  • Sprinkler overspray constantly wetting fence base
  • Low-lying area collecting rainwater
  • Wood species not suitable for ground contact

Recommended Steps

  • 1Check if rot affects one specific post or multiple — isolated rot may indicate buried leak
  • 2Check soil moisture around rotted posts with a probe
  • 3If one area is consistently wetter than others, call for underground leak assessment
  • 4Improve drainage away from affected area
  • 5Replace rotted posts with pressure-treated or cedar rated for ground contact
