Should I Repair or Replace My Fence?

Average UK labour and parts costs — always get multiple quotes from local engineers.

Softwood timber fencing lasts 10–15 years without treatment, 15–25 years with regular application of preservative. Hardwood lasts 25–35 years. Composite fencing lasts 25–30+ years. The fence posts are the critical component — once they rot at ground level, the panels become unstable.

Individual panel and post replacements are almost always the right call for isolated damage — replacing just what's broken is far cheaper than a full new fence. Annual treatment with wood preservative dramatically extends the life of softwood fencing. Only replace the full run when the majority of posts have rotted or panels are universally damaged.

The most common fence type in UK gardens is the lap panel — affordable (£20–£40 per panel) and quick to install, but relatively fragile in strong winds and prone to rot without regular treatment. Closeboard (featherboard) fencing is sturdier, with individual vertical boards nailed to horizontal rails. It's more wind-resistant, easier to repair (just replace individual boards), and lasts longer — but costs roughly 50% more. Composite fencing has grown in popularity and offers a virtually maintenance-free option that won't rot, warp, or need painting. It typically costs £80–£120 per metre fitted and lasts 25–30+ years. When deciding whether to repair or replace, your fence type matters — lap panels are often cheaper to replace entirely, while closeboard and composite are more economical to repair section by section.

• Multiple posts rotting at ground level — if more than a third of the posts are soft or crumbling at the base, replacing the entire fence run is usually more cost-effective than individual post repairs.
• Panels repeatedly blowing out — if the same panels keep failing in storms despite being replaced, the posts or fixings may be too weak to support them properly.
• Significant leaning or instability — a fence that leans noticeably or wobbles when touched usually has failed posts or an inadequate foundation.
• Widespread rot or fungal growth — dark, soft, spongy wood across multiple panels indicates the timber has not been treated and is past the point of saving.
• Boundary dispute or change of height needed — if you're increasing fence height or clarifying a boundary line, a full replacement is usually the cleanest solution.

Regular maintenance dramatically extends fence life and saves money long-term. Applying a quality timber preservative or fence paint costs around £10–£25 per metre when done yourself and should be done every 2–3 years for softwood panels. Checking and tightening post fixings annually after winter storms takes minutes but prevents expensive failures. For new installations, using concrete or metal posts instead of timber can effectively double the overall lifespan of your fence, as it's almost always the posts that fail first. In England and Wales, boundary fences don't generally require planning permission if they're under 2 metres high (or 1 metre if adjacent to a highway), but it's always worth checking with your local council before making changes.

Fencing is one of the most common home maintenance jobs in the UK, especially after winter storms. Many fence repairs are achievable DIY projects that only need basic tools, but larger structural jobs are best left to a professional fencer — particularly if you need to keep the boundary secure quickly.

Safe DIY Repairs

• Replacing individual broken fence panels — save £80–£150 per panel. Standard 6x6ft lap panels cost £20–£40 each. Lift the old panel out of the slotted posts and slide the new one in.
• Fixing a leaning post with a concrete repair spur — save £60–£100 per post. A galvanised repair spur bolts to the existing post base and is concreted in. Much easier than digging out the old post.
• Treating and re-staining weathered fence panels — save £100–£200 for a typical garden. A 5L tub of fence treatment costs £15–£25 and covers 15–20 panels. Apply in dry weather for best absorption.

Always Hire a Professional

• Replacing rotten concrete or timber posts along a full boundary (£60–£120 per post installed) — Concrete posts are extremely heavy and require proper depth (minimum 600mm). A professional ensures correct alignment and structural integrity.
• Installing fencing on a slope or stepped boundary (£80–£150 per metre) — Requires precise measurement, stepped panel cutting, and sometimes bespoke frames. Poor levelling looks unsightly and creates gaps.
• Close-board or featherboard fencing installation (£70–£130 per metre) — More complex than panel fencing — arris rails must be mortised into posts at correct spacing, and individual boards need consistent overlap.

Always check boundary ownership before replacing a fence — your property deeds or the Land Registry title plan will show which boundaries you’re responsible for.
