Storm damage triage
After a storm, triage prioritises anything posing an immediate hazard — a fence leaning over a path, a snapped post near a driveway — ahead of cosmetic damage further along the same run.
A wider survey of the whole boundary is worth doing at the same visit, since storm stress often weakens bays that haven't visibly failed yet but are more likely to fail in the next event.
The 2m permitted development height limit
Under permitted development rights, a new or replacement fence, wall or gate can generally reach up to 2 metres in height without planning permission, away from a road used by vehicles.
That height is measured from the natural ground level on the lower side where there's a change in level, which can make a fence look and function as taller than 2m when viewed from the raised side.
These are general rights and can be restricted or removed on individual properties, so checking with the local planning authority before installing anything close to the limit is sensible.
Removing or working around hedges
A mature hedge along a boundary line often needs partial removal or heavy cutting back before a new fence can go in behind or in place of it, and stump and root removal is usually a bigger job than the hedge above ground suggests.
Where a hedge is being kept and a fence added behind it, root disturbance during digging needs the same care as any other established planting — cutting a major root to fit a post line can visibly stress or kill the hedge over the following season.
Some hedgerows, particularly older boundary hedgerows in a rural or semi-rural setting, are protected under separate hedgerow regulations, so it's worth checking before removing one entirely rather than just cutting it back.
Sourcing reclaimed or discontinued timber to match an existing run
Older properties sometimes have a fence built from timber sections, profiles or panel sizes no longer in standard production, which makes an exact match difficult without sourcing reclaimed stock or having a bespoke run cut.
Reclaimed timber needs the same checks as new stock — treatment condition, rot, and structural soundness — before reuse, since visually matching timber that's structurally compromised isn't a genuine repair.
Where matching isn't practical, agreeing a deliberate, tidy transition point with the client (a change of panel style at a natural break, like a corner post) usually looks better than trying and failing to blend two slightly different materials seamlessly.
Corner visibility splays affecting fence height specifically
Some corner plots have a specific visibility splay condition attached to their planning history that limits fence, hedge or wall height at the junction to well below the normal 1m road-facing limit.
This is separate from the general permitted development height rule and takes precedence where it applies, since it's usually tied to road safety at a specific junction.
Checking the property's planning history for this kind of condition before fencing a corner plot boundary avoids building something that later needs cutting back.
Drainage easements running under a fence line
Some boundaries have a formal drainage easement recorded against the title, protecting a buried pipe or watercourse that a neighbouring property has the right to maintain access to.
Fence posts set directly over or immediately alongside a protected drainage run can technically breach the terms of the easement even if the pipe itself isn't damaged during installation.
Checking the title register, and asking the water company to confirm any known drainage records, is sensible before digging post holes on an older plot with an unclear drainage history.
When a boundary dispute reaches a solicitor's letter
A formal 'letter before action' from a solicitor is usually a sign that informal resolution has broken down and one party is preparing to escalate a boundary or fencing dispute further.
Receiving one doesn't automatically mean court is inevitable, but it does mean the matter should be taken seriously and responded to, ideally with professional legal advice rather than informally.
Most fencing disputes never reach this stage, but knowing the general process exists helps put an early disagreement into perspective before it escalates unnecessarily.
Arris rail mortice joints as a water trap
The mortice joint where an arris rail meets a post is a natural place for water to collect, since the joint interrupts the smooth run of both timbers and can hold moisture in the gap even after the surrounding wood has dried.
This is a common early failure point on older featherboard fencing, where the rail can rot through at the joint while the rest of the rail well away from the post remains sound.
Modern galvanised joist-hanger-style brackets used instead of a traditional mortice avoid this trap entirely, which is why many newer close-boarded fences use bracket fixings even where the visual style still resembles a traditional arris rail panel.
Footway licences for materials on a pavement
Storing fencing materials, a small skip, or scaffolding on a public footway, even briefly, can require a licence from the council responsible for that stretch of highway.
This is separate from any parking suspension for a vehicle, and covers the physical obstruction of pedestrian space rather than the road itself.
On narrow residential pavements it's worth checking the council's footway licence requirements ahead of a delivery, since blocking a pushchair or wheelchair route without authorisation can draw a complaint.
Wind load: solid panels versus slatted screens
A solid close-boarded panel presents its whole face to the wind, so on an exposed run the load transferred into the post is far higher than the same height in a slatted or louvred screen with even small gaps between boards.
Manufacturers' span tables for solid panels assume a sheltered suburban garden; on an open plot the safe bay width between posts often needs reducing rather than relying on the standard 1.8m centre.
Where the client wants privacy rather than a windbreak, a slatted design with a close-boarded section lower down still cuts load noticeably while keeping most of the screening effect.
Adjusting post heights when repairing a fence on sloping ground
A fence stepped down a slope has posts of varying heights above ground even though the panels themselves are a standard size, and a repaired post needs to match the stepped height of its neighbours rather than a single standard measurement.
Getting this wrong on a repair creates a visible kink in the top line of an otherwise consistent stepped run, so measuring the actual height of the posts either side of the repair matters more here than on a level run.
Earthing and bonding requirements for a substation compound fence
A metal fence around an electrical substation compound needs to be correctly bonded to the site's earthing system, since an ungrounded metal fence near live electrical equipment can become dangerously energised under fault conditions.
Bonding work at a substation compound is carried out to the network operator's own specification rather than a general fencing standard, and a fencing contractor working on this type of site coordinates closely with the operator's engineers on sequencing and isolation.
Boundary fencing for HMOs and multi-occupancy buildings
Houses in multiple occupation often have higher footfall through shared external areas than a single-family home, which points toward more durable gate hardware and fencing specified for frequent use rather than the lighter fittings suited to a quiet family garden.
Bin and cycle storage for several households sharing one plot needs more space and more robust screening than a single-household equivalent, and is worth planning at the same time as any boundary work.
Landlords managing several such properties often prefer a single consistent spec across their portfolio, both for cost predictability and so that future repairs use readily available standard parts.
Handling heavy gate posts and large timbers safely
A large hardwood or oversized gate post can be too heavy to lift and position safely by hand, particularly into a deep hole, so a simple lifting aid such as a sack truck, roller bars or a block and tackle reduces the risk of a manual handling injury.
Lowering a heavy post into a hole under control, rather than dropping the last stretch, also protects the hole's sides from collapsing under the impact just as it's being positioned.
Where a post genuinely needs mechanical assistance to move safely, planning that equipment into the job at the outset avoids improvising with inadequate lifting methods on the day.
School and nursery boundary rules
School and nursery boundaries are typically specified higher than a domestic fence and without footholds, finger-trap gaps or climbable rail patterns, because the boundary has to keep young children in as well as keep intruders out.
Gate self-closing and self-latching, non-climbable infill and a lockable-from-outside-only pedestrian gate are common requirements checked against the site's own policy rather than a general rule of thumb.
Construction hoarding versus the permanent boundary
Temporary site hoarding during a build is a separate specification from the permanent boundary that eventually replaces it — hoarding is chosen for site security and public safety during works, often under a party wall or highways licence, while the permanent fence is chosen for the finished property.
Where a boundary needs both, it's worth planning the sequence so the permanent fence isn't installed and then damaged by ongoing construction traffic before the build finishes.
Hoarding on a public highway usually needs its own licence from the council, separate from any planning permission covering the building work itself, and unlicensed hoarding on a footway can be removed by the authority.
Balancing delivery scheduling with retail service yard security
A retail service yard often needs its security gate open for scheduled delivery windows through the day, which creates a predictable gap in the site's perimeter security that opportunist theft can exploit if the yard isn't otherwise supervised during those hours.
A visitor or delivery intercom paired with a smaller pedestrian gate lets staff manage vehicle access without leaving the main gate open for the full delivery window, reducing the time the yard is left unsecured.
Garden levels raised by decking or patios
A raised deck or built-up patio on one side of a boundary can leave the finished surface level noticeably higher than the fence's original ground-level reference, sometimes reducing the effective fence height as seen from that side.
Where a neighbour raises their ground level after a fence is already installed, drainage that previously ran away from the fence can be redirected toward it, so it's worth checking finished levels on both sides before agreeing a new fence height or base detail.
A fence installed at the same time as a client's own raised patio should account for the new level from the outset, rather than being set to the pre-existing grade and later needing extension.
Letterbox and parcel provision in a secure gate
A fully secured pedestrian gate can leave deliveries with nowhere to leave post or parcels, so a secure gate-mounted letterbox or a parcel box positioned outside the locked line is worth planning at design stage.
Positioning it so it can be reached without opening the gate keeps the boundary genuinely closed while still allowing routine deliveries.
Checking for older asbestos-containing gravel boards before repair
Some older fence installations used asbestos-cement gravel boards or panels, which look similar to concrete at a glance but need identifying and handling differently if disturbed during a repair.
Where a boundary fence predates the ban on asbestos cement products and shows a grey fibrous-looking board rather than standard reinforced concrete, it's worth having it checked before cutting, breaking or disposing of it as ordinary waste.
A boundary at the bottom of a slope
A fence line at the foot of a slope collects both surface run-off and, on clay, a slower seepage of water moving through the ground itself, so the ground here is often wetter and softer than the rest of the plot.
Post bases in this position benefit from a raised free-draining collar rather than concrete flush with the surrounding grade, keeping standing water away from the timber-to-concrete joint.
It's also worth checking whether the fence itself is inadvertently damming water that would otherwise continue draining downhill off the plot entirely.
Repairing a post snapped clean at the ground line
A post that's sheared off flush at the ground line has usually lost most of its strength to rot just below the surface before the final break, which is often triggered by wind load or someone leaning a ladder against the panel.
The stub left in the ground is dug out or broken free of the old concrete rather than built around, since leaving it in place gives the new post nothing solid to bear against and the repair fails again within a season.
