Common Mistakes to Avoid
❌ Not going deep enough for posts
Posts should be buried 1/3 of their length + 6 inches below frost line. A 6ft fence needs 9ft posts with 3ft buried.
❌ Forgetting gates
Gates require extra hardware, frame lumber, and may need larger posts. Budget separately.
Frequently Asked Questions
How deep to bury fence posts?
1/3 of post length minimum, or below local frost line (whichever is deeper). Shallow posts heave and lean.
Wood vs vinyl fence?
Wood: lower upfront, needs maintenance. Vinyl: higher upfront, virtually no maintenance, won't rot or warp.
Fence permit required?
Most jurisdictions require permits for fences over 4-6 feet. Check HOA rules too.
