Fence post repair fixes the three most common Canadian fence failures: rotted wood posts at grade line, leaning posts from frost heave, and broken posts at the concrete top. Each has a distinct repair method and cost. This page covers DIY repair, when to call a pro, and how much each job runs in 2026.
Three common post failures
1) Rotted wood post at grade line. Pressure-treated and cedar wood posts rot fastest at the soil/air interface where moisture cycles between wet and dry. Symptoms: wobble when you push the fence; visible rot at the base; soft wood that crumbles. Repair: cut the post off above the rot line and either (a) splice with a steel post-saver sleeve driven beside the rotted base, $30-60 supply per post, $80-150 installed, or (b) excavate the entire post and concrete, replace with a new pressure-treated 4×4 in fresh concrete, $80-150 in materials plus 2-4 hours labour per post.
2) Leaning post from frost heave or wind. Wet clay soil that freezes and thaws lifts shallow posts every winter. Wind on a privacy fence rotates posts in soft soil. Repair: pull the post plumb, fill the void with crushed stone or fresh concrete, install a metal post anchor or T-anchor below the concrete bell. Cost: $40-80 in materials per post, $100-200 installed.
3) Snapped post above concrete. Vehicle impact or a fallen tree snaps a post at the concrete top while leaving the base intact. Repair: cut the broken stub flush, drill and epoxy a steel pin or threaded rod into the existing concrete, slide a steel post-sleeve over the pin and bolt the new post into it. $50-120 materials, $150-300 installed.
When to call a pro
Call a contractor when: the fence is over 6 ft tall (privacy panels are heavy), the post is on a sloped or rocky lot (excavation gets hard), gates are involved (alignment matters), or you have more than 3-4 posts to repair (labour adds up; DIY is one weekend per repair). DIY makes sense for single-post repair on flat terrain in soft soil.
Cost ranges in Canada 2026
Single post repair by a contractor: $150-400 per post depending on city and access. Multi-post repair (5-10 posts): $100-250 per post with volume discount. Full post replacement including new concrete footing: $200-450 per post. Add gate post replacement (oversized footing): $400-800 per post. Emergency / weekend rates: 20-40% surcharge.
