Why Do Wood Fences Fail—and How Can You Prevent It?
For most homeowners, fences break down not because the boards wear out, but because the posts rot, crack, or shift. The most effective upgrade—especially for wood fences—is choosing hidden steel fence posts. At Fantastic Fence, over 80% of new projects use these posts for a reason: they are tougher, more durable, and keep fences standing long after wood posts would fail.
A Recommended Manufacturer:
Steel posts:
- Won’t rot, warp, or buckle
- Withstand wind, moisture, and ground movement
- Can be wrapped to look like traditional wood but deliver decades of strength
The Problem with Modern Pressure-Treated Wood Posts: ACQ40 Changes
Wood posts are now mostly pressure-treated with Alkaline Copper Quaternary (ACQ40), replacing older CCA formulas for safety.
- ACQ is less toxic, but less effective: Posts rot much sooner in wet conditions (often in 5–10 years).
- Official guides:
Bottom line: ACQ is safer for families but comes with a tradeoff in durability compared to old pressure-treatments. For a fence post that lasts, steel wins hands down.
Enhance Fence Longevity – Yearly Wood Fence Maintenance & Inspection
A little preventative care goes a long way in helping your wood fence stand strong for years. Make these steps part of your annual maintenance routine:
- Inspect Posts:
Each year, walk your entire fence line and check every post—especially near the ground—for rot, softness, leaning, or looseness. Rotten or unstable posts should be replaced as soon as possible to avoid bigger problems. - Look for Damage:
Examine boards and rails for cracks, splitting, warped wood, or loose nails and fasteners. Repair or replace any problem spots right away. - Clean Thoroughly:
Remove dirt, mildew, algae, and debris using a mild soap and water solution and a soft brush. Rinse thoroughly. This prevents buildup that holds in moisture and accelerates rot. - Apply Sealant or Stain:
Protect your fence from moisture and sun by reapplying a quality wood sealant or stain every 2–3 years, or as the manufacturer recommends. Always allow the fence to dry completely before sealing. - Trim Vegetation:
Cut back bushes, vines, and branches touching or growing near the fence. Keeping plants away improves airflow and reduces trapped moisture and stops mold and decay in their tracks. - Check Gates and Hardware:
Tighten and lubricate gate hinges, latches, and hardware. Make sure gates swing smoothly and are properly aligned. - Watch for Pests:
Inspect for termites or other wood-boring insects. Address infestations promptly by calling a pro if needed. - Address Drainage Issues:
Make sure water isn’t pooling at the base of your fence. Add soil or improve drainage as needed to keep posts dry.
By doing these simple checks every year, you’ll spot small issues before they become big expenses—and help your wood fence last for decades longer.
