Choosing fence post material

Concrete vs Timber Fence Posts

Fence panels get all the attention, but posts are what fail. Choosing between concrete and timber is the single biggest decision for the life of a boundary.

There is a reasonable case for each.

The case for concrete

Concrete posts do not rot, so a fence built on them can outlast several sets of panels. Slotted posts make future panel replacement quick and simple with no fixings to undo.

They are heavier to handle and less attractive close up, but largely hidden once panels are in.

The case for timber

Timber posts look better on a fence that is on show, take fixings anywhere for closeboard, trellis or arris rails, and can be cut and shaped on site.

Ground-contact-rated pressure treated timber, set with drainage and a shed-water concrete finish, lasts a long time — the failures we see are usually poorly set posts, not poor timber.

Mixing the two

A common practical compromise is concrete posts along the exposed, hard-to-access boundary and timber where appearance matters, or timber posts in metal post shoes to keep wood out of the ground.

Gate hinge posts should always be the strongest option available.

Frequently asked questions

Do concrete posts crack?

Reinforced posts are durable; damage is usually from impact rather than weathering.

Are timber posts cheaper?

Usually slightly, though the difference is small next to the labour of replacing them early.

Can I fit closeboard to concrete posts?

Yes, with slotted posts taking gravel boards and rails, or by fixing rails to the posts.
