A leaning fence is not safe merely because it is still standing. Wait until the wind has passed, keep people and pets clear of loose panels, and look for the cause from a safe position. A loose bracket, rotten timber post and moving concrete footing need different repairs. Before digging, check for buried services. Before replacing a boundary fence, speak to the neighbour and check the title documents and local rules. UK insurance policies often exclude fences from storm cover.
Hi there, fellow DIYer,
The tempting fix is to push the panel upright and screw on a prop. That may hold for a day, but it can put someone directly in the path of a falling panel. Start with safety, then inspect the post, base and fixings.
Immediately after the storm
The Met Office says not to go outside to repair storm damage while the storm is in progress. Once conditions are calm, photograph the fence from a safe distance. Keep children and pets away from a leaning panel. If it threatens a public path, road, neighbour’s property or overhead cable, contact the appropriate local authority or service and use a competent contractor.
Do not stand beneath a half-detached panel, pull it towards yourself or try to hold it alone. Fence panels can be awkward sails even in a moderate gust. If a loose section must be removed, plan the work with enough people and temporary support for the size and weight involved; use a contractor when it is beyond safe handling.
Diagnose the failure
| What moves? | Possible cause | Likely repair |
|---|---|---|
| Panel shifts while posts stay firm | Failed brackets, fixings or a damaged panel | Replace suitable fixings or the panel |
| Timber post bends or feels soft at ground level | Rot or a crack in the post | Replace the post; a prop is not a permanent repair |
| Post and its footing move together | Loose foundation or disturbed soil | Rebuild the footing to a suitable design |
| Concrete post is cracked or broken | Structural damage | Replace the post, often with professional help |
| Several posts lean in the same direction | Wider fence or ground problem | Assess the whole run before buying parts |
A visibly rotten post cannot be made sound by pulling it upright. Likewise, a heavy concrete post and attached gravel boards may be unsafe for one person to remove. Get a fence installer where several posts are involved, ground is unstable or the boundary faces a public area.
A photograph of the whole run, the base of each failed post and the panel connections will make quotes easier to compare. Ask a contractor to separate temporary making-safe work from the permanent repair.
Before you dig or reset a post
Never assume there are no pipes or cables because the hole is in a garden. HSE guidance on underground services describes a safe sequence: plan the excavation, locate and identify services, then dig by an appropriate method. Electricity cables can be fatal if struck. Ask a competent contractor or service operator for help if routes are unclear. Do not drive a spade, post spike or breaker into an unknown line.
A replacement post, footing and fixing must suit the fence height, ground and local wind exposure. There is no universal “one-third buried” rule or fixed amount of fast-setting concrete that makes every fence safe. Follow the post and concrete manufacturers’ instructions and allow full curing before hanging a panel. A post support that keeps timber above ground may be useful where it is designed and installed for the loads, but it does not compensate for an inadequate footing.
Do not lean an unstable panel against a neighbour’s fence or building. Do not work beyond your own boundary without agreement.
Boundary, planning and insurance
In England and Wales, GOV.UK says there is usually no record of who owns a particular fence between two properties, and title plans rarely show an exact boundary line. Check the deeds or any agreement, then talk to the neighbour before changing a shared line. Scotland and Northern Ireland have different property systems, so use the relevant local route.
If replacing a fence with a different height or position, check planning and any conservation, listed-building, road or tenancy restrictions for your location. The Planning Portal’s England guidance gives common height limits, but it is not a blanket permission for every UK property.
Do not assume buildings insurance will pay for a fallen fence. The Association of British Insurers says storm damage to fences and gates is generally excluded from standard buildings policies. Check your own wording and any special cover before spending on an assumed claim. Photograph the damage and keep invoices if you contact the insurer.
A repair brief worth writing down
| Question | Your note |
|---|---|
| Which panel or post failed? | |
| Is the timber sound at ground level? | |
| Does the footing move? | |
| Are buried service routes known? | |
| Who owns or maintains this boundary? | |
| What temporary support keeps people clear? | |
| Is the replacement height or position changing? |
Once the fence is safe, fix the failed part rather than just straightening its appearance. The soundness of the post and footing, the service routes underground and the neighbour’s position matter more than a quick prop.
