⚡ CalcWolf Insight

The most common fence failure: inadequate post depth. Posts should be 1/3 below ground (minimum 24 inches for a 6-foot fence) and set in concrete. Gravel-only posts lean within 2-3 years. Concrete costs $3-5 per post and adds decades to fence lifespan. This is not the place to cut corners.
