Quick Answer
Inspect livestock fences at minimum twice yearly (spring and fall) as a thorough walkthrough, plus a monthly voltage check for electric fences during grazing season. Immediately after any storm, equipment contact, or witnessed livestock breakthrough. A thorough inspection takes 1–3 hours per mile of fence and prevents the escape incidents and fence damage that missed problems cause.
Minimum Inspection Schedule
| Inspection Type | Frequency | Duration | What to Check |
|---|---|---|---|
| Voltage test (electric) | Monthly | 15–30 min | Voltage at energizer and far end |
| Visual walkthrough | Quarterly | 1–2 hrs/mile | Posts, wire, insulators, vegetation |
| Full inspection | Twice yearly (spring/fall) | 2–4 hrs/mile | All components, test post stability |
| Post-storm check | After any major storm | 1 hr | Fallen branches, wire breaks, leaning posts |
| Post-breakthrough check | After any escape | Complete | Identify and fix the breach point |
What to Look for During Inspection
Posts: Rock each post — movement of more than 1 inch indicates base failure. Probe wood posts at the soil line with a screwdriver — soft wood signals active rot. T-posts that have shifted from vertical need to be re-driven.
Wire: Look for broken strands, kinks, excessive sag, or wire that has slipped off insulators. On electric fences, check that wire is not touching post or vegetation at any point.
Insulators: Look for cracks, UV yellowing, arcing marks, or insulators that have cracked loose from the post. Replace any questionable insulator — they cost $0.25–$1.00 and take 2 minutes to replace.
Vegetation: Heavy grass or weeds touching wire significantly drain voltage. Trim or spray as part of the spring inspection.
Record Keeping
Keep a simple fence inspection log: date, sections inspected, voltage readings (electric), repairs made, items to follow up. A 5-minute record per inspection creates a history that makes troubleshooting much faster — you can immediately see whether a problem is new (storm damage) or progressive (gradual post failure).
Our Recommendation
Add fence inspection to your spring and fall farm maintenance routines — it takes 2–4 hours per mile and prevents the vast majority of escape events and fence failures. A fence that is inspected twice yearly costs significantly less in reactive repairs than one inspected only when problems become obvious.
