Fence Repairs in Sawston

Why fence problems rarely fix themselves

A fence that looks slightly tired today can be genuinely unsafe within a season. Posts that have started to lean, boards that have begun to split and gravel boards sitting in wet soil are all telling you something. Ignoring those signs usually means a larger repair bill later, or a panel down after the next bout of wind and rain.

Haverhill Fencers repair fences across Sawston and the villages nearby. We replace what needs replacing - whether that is a single post, a few boards or a whole section - without disturbing the rest of the run.

The warning signs to look for now

Most fence failures give you plenty of notice if you know what to look for. Walk the boundary and check each of these carefully.

Leaning or rocking posts

A post that rocks when you push it is the single most important warning sign. Posts are usually set in concrete, but the concrete itself can crack over time, and the post inside it will rot at the point where it meets the ground - even pressure-treated timber eventually breaks down below soil level. Once a post is structurally weak, any panels it supports are at risk. A leaning post does not recover on its own.

Push each post gently at the top. Any movement at all means the base needs inspection. Sometimes the post can be re-set with a new concrete collar. More often, by the time the lean is visible, the timber below ground is soft enough to need a full post replacement.

Soft or discoloured wood at the base

Rot almost always starts low down, where the timber is in contact with soil, leaf litter or a poorly fitted gravel board. Dark staining, a spongy feel when you press a screwdriver tip into the wood, or paint bubbling away from the surface are all signs of active decay. A fence post or board in this state will not respond to preservative treatment - the rot is already through the outer layers. Replacement is the only lasting fix.

Panels moving independently of the posts

If a panel shifts when there is wind but the posts feel solid, the fixings have failed. This happens when the arris rail brackets corrode, when the rails themselves split, or when boards have pulled away from the rails over time. A panel in this state can come down in a moderate gust, which is a hazard if you have children or pets in the garden.

Cracked or split boards

Individual boards split as the timber dries and wets repeatedly over years. A crack along the grain of a featherboard or close-board panel is not immediately structural, but it lets water in and accelerates decay. Replacing a handful of boards before the panel fails is straightforward and inexpensive compared with replacing the whole section.

Gravel boards sitting in wet ground

The gravel board at the bottom of a panel run is there specifically to take the rot so the panels above do not have to. When a gravel board fails - crumbling at the edges, soft to the touch, or simply missing - soil and moisture start working directly on the panel itself. Concrete gravel boards are worth considering as a replacement because they do not rot, but they add weight to the run and the posts need to be in good condition to carry it.

What causes fences to fail?

Understanding the cause matters because it affects what the right repair actually is. Replacing a rotten post without addressing why it rotted can mean the same problem returns within a few years.

• Soil contact: Timber in direct contact with soil will rot, even if treated. Gravel boards should be the only thing at ground level, with the panels above kept clear.
• Standing water: Low-lying ground or poor drainage accelerates rot. In these situations, concrete posts or a concrete gravel board combined with good timber above ground is a practical choice.
• Wind loading: A long, solid panel run catches a lot of wind. Panels near corners or on exposed sides of a garden fail before the rest. Checking those spots first after any significant storm is good practice.
• Age and original specification: Much domestic fencing is built to a budget and uses untreated or lightly treated timber. After ten to fifteen years, decay is common throughout the run even if it only shows in one or two places.
• Storm damage: A single severe weather event can bring down panels that were borderline anyway. It can also crack arris rails, split posts or pull fence posts out of their concrete at the base. The damage is often more widespread than it first appears - check the whole run, not just where it is obviously down.

Repair or replace - how to think about it

A repair makes sense when the posts are sound, the rails are intact and the damage is limited to boards, fixings or a single panel. If the posts are soft, if multiple sections are leaning or if the overall run is more than fifteen years old and showing widespread decay, a full replacement is usually better value than patching a failing structure.

Typical costs for fence repairs in the UK sit broadly between £150 and £400 per section depending on what needs doing. A straightforward post replacement including concrete and labour tends to run from around £100 to £200. Replacing a full panel section with post and gravel board can reach £250 to £450 depending on the panel type and ground conditions. These are honest working ranges - an accurate figure depends on what is found on the day.

Ask any fencer to tell you what they are replacing and why before they start. A proper inspection of the posts and rails, not just the visible boards, will give you a much clearer picture of what the job actually involves.

What we repair and where

We handle fence repairs across Sawston and travel to neighbouring areas. Jobs range from a single damaged post after a storm to full section replacements on longer boundary runs.

We work with close-board, featherboard, lap panel, post and rail and picket fencing. If you need a gate repaired or rehung as part of the same job, we can deal with that at the same time.
