Concrete vs Timber Fence Posts
Posts decide how long a fence lasts. Concrete outlives timber comfortably; timber looks better and takes fixings anywhere.
When we take down a failed fence, the panels are usually salvageable and the posts are not. Choosing posts is therefore the highest-leverage decision in the whole job.
Why fences fail at ground level
The zone 50mm either side of soil level stays alternately wet and aerated — perfect conditions for rot. Timber posts fail there first, which is why a fence can look fine from the patio and snap in the first serious gust.
The case for concrete posts
Slotted concrete posts with concrete gravel boards keep every piece of timber clear of the soil. Panels then slide in and out, so future maintenance becomes a ten-minute panel swap rather than a rebuild. On rental properties and long runs this is nearly always the right call.
The case for timber posts
Timber looks warmer, suits conservation frontages and closeboard runs, and accepts fixings anywhere along its length — essential for gates, trellis, lighting and raked panels on a slope. Well-chosen posts set correctly with a drainage layer beneath, not sitting in a bucket of water, give good service.
Concrete spurs — the middle option
Where one post has snapped but the fence is otherwise sound, bolting the sound upper timber to a concrete spur is a legitimate, economical repair. It is not a bodge if the spur is properly based; it is what we use to buy a fence several more years.
Frequently asked
How deep should a fence post go?
As a working rule, at least a quarter to a third of the post's total height, deeper on exposed runs, gate posts and loose ground.
Should posts sit in concrete or postcrete?
Either works when the hole is the right size and the base drains. What matters is the collar shedding water away from the post, not the brand of mix.
Can I put concrete posts in without replacing panels?
Often yes, if panel widths match the post slots. We check dimensions before quoting a mixed approach.
Do concrete posts look industrial?
Less than they used to. Paired with gravel boards and a trellis or capped top, most clients stop noticing them within a week.
