How deep should fence posts be set?+
The general rule is to bury 1/3 of the post length underground. For a 6-foot fence, use 9-foot posts buried 3 feet deep. In frost-prone areas, posts must extend below the frost line (typically 30–48 inches) to prevent frost heaving. Use concrete or gravel for post footings.
What type of fencing lasts longest?+
Aluminum and vinyl fencing are the most low-maintenance, lasting 20–30+ years. Chain link lasts 15–20 years. Pressure-treated wood lasts 10–15 years with maintenance. Wrought iron can last 50+ years but requires rust prevention. Choice depends on budget, aesthetics, and climate.
