Resetting versus replacing a post
A post repair is either a reset in fresh concrete where the timber itself is sound, a concrete spur bolted above a rotten section where enough good timber remains, or a full replacement where rot has reached the panel fixings.
We test each post on site with a probe at ground level rather than deciding from a visual check alone, since a post can look fine above ground and be rotten just below it.
Clearing storm and repair debris
Broken panels, snapped posts and old concrete are cleared and taken off site as standard on any repair, rather than left in the garden for the client to deal with separately.
Where a repair follows a storm, we also check for and clear any debris that's blown into the garden from elsewhere, not just the fence materials themselves.
Adjustable bolt-on hinges for metal gates
Adjustable bolt-on hinges, common on metal driveway gates, let the gate's height and pitch be fine-tuned after fitting via a bolt and welded bracket rather than needing the hinge repositioned entirely.
These are useful where ground level or post position isn't perfectly fixed, since small adjustments can be made without unbolting the gate from the post.
Checking whether an existing post can be reused
A post that looks sound above ground can still have rotted through at the point where it meets the concrete, so a proper check means levering the post gently and looking for movement at the base, not just inspecting the visible timber.
Concrete posts rarely rot but can develop hairline cracks from impact or corroding internal reinforcement, which shows up as rust staining bleeding through the surface before the crack itself is obvious.
Reusing a post that fails a proper check to save a day's digging usually costs more later, since replacing one post in an otherwise finished run means disturbing the panels either side of it.
Fixing a post that has rotated in its concrete base
A post can twist within a slightly oversized or cracked footing without leaning, so the panels either side pull out of square even though the post still stands upright, which is easy to miss on a quick visual check.
Repair means breaking out enough concrete to free the post, resetting it square to the run, and packing and re-pouring rather than trying to twist it back while still gripped by the old footing.
Gate swing on a sloped driveway approach
A driveway gate installed at the top or bottom of a sloped approach needs its swing arc checked against the actual gradient, since a gate that clears the ground when closed can still catch the rising slope partway through its opening arc.
Sliding gates are sometimes preferred over swinging gates on a sloped approach for exactly this reason, since they don't need to clear a changing ground level along their travel.
Gate frame timber sizes by width
A gate frame's timber section needs to increase with the width of the opening, since a wider gate has more leverage acting on the hinge side and more unsupported span across the middle before diagonal bracing is added.
A narrow single pedestrian gate can often use a modest frame section, while a wide double-leaf driveway gate needs substantially heavier stiles and rails plus a diagonal brace to stop it dropping or racking out of square at the latch side.
Bracing should run from the top of the hinge side down to the bottom of the latch side, in the direction that actually resists the gate's tendency to sag, not simply corner to corner for appearance.
Recycled plastic fence posts
Posts made from recycled plastic, sometimes blended with additives for UV resistance and rigidity, avoid timber's rot and insect vulnerability entirely, since the material has no organic content for fungi or insects to attack.
They tend to be more flexible than an equivalent timber section of the same size, which can be an advantage in absorbing impact but a disadvantage where rigidity is needed to resist sustained wind load without visible sway.
Their thermal expansion behaviour is closer to other polymer products than to timber, meaning fixings and adjoining materials need similar allowance for movement as with composite boards rather than being treated as a timber-equivalent product.
Housing association permissions for boundary work
Housing association and council tenants typically need written permission before altering a garden boundary, even for straightforward like-for-like fence replacement, under the terms of their tenancy agreement.
Some landlords have a specific alterations request process and approved list of acceptable fence types or heights, which can differ from what a private neighbour might choose.
Tenants planning boundary work are usually best placed to check with their housing officer first, since unauthorised alterations can occasionally need to be reversed at the tenant's cost.
Parking and material handling on site
Fencing, gates and decking all involve moving bulky, heavy material — concrete posts, gravel boards, decking joists — from a van to the working area, and how far that has to be carried has a real effect on labour time.
On streets with permit parking, no off-street loading bay, or restricted delivery hours, we plan the drop-off around those restrictions rather than assuming a van can sit outside all day.
Where a plot has a driveway or side gate wide enough for a barrow run, that alone can shave a meaningful amount of time off a job compared with hand-carrying everything round the front.
Composite thermal expansion
Wood-plastic composite boards expand and contract with temperature considerably more than solid timber, since the polymer content responds more to heat than wood fibre does on its own.
Manufacturers specify a mandatory expansion gap at both board ends and between boards laid end to end, and skipping that gap during installation is one of the most common causes of composite decking or fencing buckling in hot weather.
Dark-coloured composite absorbs more solar heat than lighter shades and expands correspondingly more, so the expansion allowance recommended for a dark board is often greater than for a pale one of the same profile.
Noise and timing considerations on a repair
Cutting timber or breaking out old concrete can be noisy, and giving a neighbour advance notice of a repair on a shared boundary avoids unnecessary friction, particularly on a terraced row where several gardens sit close together.
Timing louder stages of a repair to reasonable hours is a simple courtesy that costs nothing and reduces complaints on tightly packed sites.
Checking mesh tension across seasonal temperature changes
Steel mesh infill expands and contracts slightly with temperature across the year, and a mesh tensioned tight in cold winter conditions can develop a visible sag by the height of summer if the original tensioning didn't allow for that movement.
A seasonal tension check, particularly after the first full year following installation, catches this early and allows a simple re-tensioning before a sagging mesh starts to create a usable foothold or gap at the base.
Choosing post hole diameter for the post size
A hole cut too close to the post's own width leaves no room for concrete to fully surround it, which weakens the base and gives water a direct channel down alongside the timber rather than a solid seal.
A generally quoted rule is a hole roughly three times the post's width, so a 100mm post wants in the region of a 300mm diameter hole, adjusted upward on poor ground or for taller, more heavily loaded posts such as gate posts.
Oversized holes aren't free either — they use more concrete and take longer to backfill and haunch neatly, so the aim is the right diameter for the post and ground rather than simply digging as wide as convenient.
Hit-and-miss fencing for windy plots
Hit-and-miss fencing alternates boards on either side of the rails so each gap on one face is covered by a board on the other, giving privacy from both sides while leaving narrow gaps through the panel itself.
Those gaps let a proportion of wind pass through rather than loading the whole panel face, which is why it's a common recommendation on exposed boundaries where a solid closeboard run would need heavier posts and shorter bays.
It uses more timber than a single-skin boarded fence for the same run length, so it's priced accordingly, but the reduced wind load can offset that in post and repair costs over time.
Realistic panel replacement frequency on an exposed plot
A standard timber panel on a sheltered suburban plot might reasonably be expected to last a decade or more before replacement; the same panel on a genuinely exposed, wind-loaded boundary can fail in structural terms — cracked rails, a bowed or blown-out panel — well inside that timeframe regardless of treatment quality.
Setting client expectations around this at quote stage, rather than after an early failure, avoids the impression that a product or installation was faulty when the real cause is unmanaged exposure.
Where budget allows, specifying for the exposure from the outset is cheaper over the fence's life than replacing a standard panel repeatedly on the same exposed run.
Using a post level clamp for solo plumb-checking
A post level that clips onto two adjacent faces of a post at once lets one person check plumb in both directions simultaneously without needing a second pair of hands to hold a separate level against each face.
This is particularly useful when bracing a post alone, since the clamp stays attached and visible while adjustments are made, rather than needing to remove and reposition a standard spirit level after every small correction.
It's worth checking the clamp itself is seated flat against the post with no debris or splinters holding it proud, since a level that isn't sitting flush will give a false reading regardless of how carefully the post is actually adjusted.
Curing time before hanging panels or gates
Post-fixing concrete reaches a usable strength within a day or two but continues gaining strength for weeks afterwards, which is why manufacturers usually specify a minimum wait — commonly around 24-48 hours in mild weather — before loading a post with a panel.
Hanging a heavy gate is a bigger test of an early-cured base than fixing a lightweight panel, since the gate applies a constant leverage on the post rather than a static side load, so gate posts generally want the longer end of any recommended cure window.
Cold weather slows the chemical reaction that hardens concrete significantly, so a cure time that's fine in summer may need extending in winter before it's safe to load the post.
How garden slope affects water shedding along a fence base
On a sloped garden, water naturally runs along the base of a fence line toward the lowest point, which means the downhill end of a run often sits in wetter ground than the uphill end even though both were built to the same specification.
This uneven exposure is a common reason why one end of an otherwise uniform fence needs gravel board replacement years before the rest.
A shallow cross-fall drainage channel or a slightly raised gravel board at the low point can intercept some of this flow before it pools against the timber.
Lifetime comparison of hedging and fencing as a boundary
A well-established hedge can outlast several generations of timber fencing with no post replacement or re-treatment cycle, but it needs regular cutting to stay within bounds and takes several years to reach an effective screening height from new planting.
A fence gives an immediate, defined boundary and predictable height but carries an ongoing maintenance and eventual replacement cost that a mature hedge doesn't.
Many gardens end up with a mixed solution — a fence for the immediate boundary definition with hedging planted alongside it to soften the appearance and eventually take over some of the screening role.
Flying freeholds and unusual boundary shapes
A flying freehold occurs where part of one property, such as a room, overhangs part of another below it, and can produce boundary arrangements in the garden that don't follow an obviously straight or logical line.
Properties with this kind of unusual legal history sometimes have correspondingly unusual title plan boundaries in the garden area, which are worth checking carefully rather than assumed from the visible layout.
Where a garden boundary looks like it doesn't match the physical shape of the buildings above, that's a sign worth investigating with the title documents before fencing work begins.
Weld mesh and chain link
Weld mesh panels are a rigid grid of welded steel wire, usually galvanised and often polyester-coated, and they hold their shape under impact far better than chain link, which is why they're common on boundaries needing a firmer physical barrier.
Chain link is a diamond-pattern woven wire fixed to line wires and posts rather than a rigid panel, which makes it cheaper and easier to tension over long or uneven runs but more prone to sagging or distorting under repeated pressure.
Neither offers meaningful privacy on its own, so both are frequently paired with hedging or slatted infill where visual screening is also wanted alongside the containment.
