Most people only think about their fence when a panel ends up in next door's garden after a February gale. The honest answer is that a wooden fence in the UK lasts anywhere from 5 to 25 years, and the gap between those two numbers has far less to do with the panels than with what is holding them up. Here is what actually determines how long yours will stand, based on what we see across Bristol gardens.
Timber fencing is not one product with one lifespan. A budget waney edge lap panel and a pressure treated closeboard fence are separated by two decades of service, and the price difference between them is rarely as large as people expect.
These are the ranges we would stand behind for the Bristol area, assuming the fence is properly installed and gets an occasional look over:
Nine times out of ten when we are called to a blown down fence, the panels are serviceable and one or two posts have snapped clean off at ground level. Rot happens in the few centimetres either side of the soil line, where timber is alternately wet and exposed to air. Everything above and below can look sound while that one band has turned to fibre.
This is why the cheapest way to extend a fence's life is to spend more on posts than on panels. Either use concrete posts with concrete gravel boards, or use timber posts rated UC4 for ground contact and set them so water drains away rather than pooling in the hole. A post sat in a concrete cup that holds rainwater will rot faster than one set in a well drained hole with hardcore in the base.
Bristol gets roughly 800 to 900mm of rain a year and mild, damp winters, which is a decent recipe for fungal decay. We rarely see fences dry out fully between November and March. South and west facing runs also take the brunt of the prevailing wind, and gardens on the exposed edges of the city, up on the Downs, out towards Dundry and the higher parts of Kingswood, get noticeably more storm damage than sheltered terraced plots in Bedminster or Easton.
Two very common local problems shorten fence life more than the weather. The first is soil or a raised bed banked up against the panels, which keeps timber permanently wet and can take years off a fence. The second is ivy and dense shrubs growing through, holding moisture against the boards and adding a great deal of wind loading. Clearing a 50mm gap at the base and cutting climbers back is free and genuinely effective.
Treating a fence helps, but it is often oversold. A pressure treated panel does not need annual coating to survive, and painting a damp panel can trap moisture in. What matters is a coat of decent preservative or oil every 2 to 3 years on the exposed faces, applied in a dry spell, plus keeping the base clear.
Also worth doing once a year: push firmly on each post at mid height. If there is movement or a hollow sound near the ground, that post is going. Replacing a single post while the rest is sound costs a fraction of a full run and buys you several more years.
If posts are solid and only a few panels are damaged, repair. Panels can be swapped individually and it is straightforward work. If more than about a third of the posts are soft at ground level, patching becomes false economy, because you will be back out there each winter and the labour adds up.
As a rough guide for the Bristol area, replacing a fence typically works out somewhere in the region of £60 to £120 per metre supplied and fitted, depending on height, panel type, whether you go concrete or timber posts, access, and what needs taking away. Sloping ground, tight rear access and old concrete to break out all push it up. Anyone quoting without seeing the site is guessing.
Yes, substantially. Concrete posts and gravel boards commonly last 25 years or more and will usually outlive two sets of panels, so you only ever replace the timber infill rather than digging out posts again.
No. Pressure treated timber is often still damp when delivered and needs a few months to weather before it will take a coating properly. Leave it a season, then treat the exposed faces every 2 to 3 years.
Your title deeds or the Land Registry plan are the only reliable answer, sometimes marked with a T shape on the boundary you are responsible for. The old idea that you own the fence on the left is a myth with no legal basis.
