Drainage fixes as part of a repair
Where poor drainage caused or contributed to the original failure, a repair that doesn't also address the drainage — regrading a low spot, adding a small soakaway, or fitting a concrete gravel board — risks the same failure recurring.
Addressing drainage at repair time is usually more cost-effective than repeating the same panel or post repair every few years.
Post-support metal spikes and why they loosen
A drive-in metal spike relies entirely on ground compaction around the socket for stability, so any repeated wind loading or ground softening after heavy rain gradually works the socket wider and the post starts to rock.
Once a spike has loosened it rarely re-tightens on its own; the usual fix is a larger spike bedded in fresh concrete or a switch to a concreted timber post if the ground repeatedly won't hold a spike.
Balustrade requirements on raised decking
Building regulations generally expect a guarding balustrade wherever a raised deck has a drop of around 600mm or more, with a minimum height (typically around 900mm-1100mm depending on the situation) and gaps small enough that a 100mm sphere can't pass through.
That gap rule is specifically there to stop a small child getting a head or limb through the balustrade, so wide-slat contemporary balustrade designs need checking against it just as carefully as traditional close-spaced spindles.
A deck under that drop threshold doesn't need a balustrade by regulation, but a low kerb or edge trim is still worth considering as a visual cue to the edge, particularly at night.
Bearer support on adjustable pedestals
Adjustable plastic pedestals supporting deck bearers let each support point be levelled individually, which is useful over an uneven concrete base, a sloped patio, or ground that isn't practical to excavate level.
Pedestal spacing still needs to follow the same span logic as timber joists, since an adjustable base doesn't change how far the bearer above it can safely span before it needs another support point.
Pedestals also raise the whole deck slightly, which is worth checking against a threshold or step height at the house before committing to the system.
Why corner posts fail more often and need stronger repair specification
A corner post carries the combined load of two fence runs meeting at an angle rather than a single run passing through, so it's under more sustained stress than an intermediate post and often fails first on an ageing boundary.
Repairing a corner post is worth specifying to a slightly higher standard than a mid-run post — larger section, deeper footing, sometimes additional bracing — given the extra load it carries permanently rather than only occasionally.
Gas and water service positions near boundaries
Gas and water services typically run from the property boundary to the meter position in the shortest practical line, which on many plots means they cross close to or directly under a side boundary fence.
Utility companies can usually supply a service plan on request, though older properties sometimes have connections that predate accurate record-keeping and were never mapped precisely.
Where a plan shows a service crossing the fence line, hand-digging that section and setting the post either side of the marked route avoids the need to relocate a damaged supply.
Applying for a Land Registry boundary determination
Where a boundary's exact position is genuinely disputed, it's possible to apply to HM Land Registry for a 'determined boundary', which involves a formal survey and legally fixes the line rather than leaving it as a general indication.
This process is comparatively rare for domestic disputes because of the cost and evidence involved, and is normally a last resort after direct discussion has failed.
Most everyday fence replacement work never needs this, but it exists as a formal route for the minority of cases where agreement genuinely can't be reached.
Which side a fence's face and posts should sit on
There's a long-standing but informal convention that the 'good side' — the smooth face without visible posts and rails — should face the neighbouring property, though this is a courtesy rather than a legal requirement.
Some title deeds do specify a required orientation as part of an ownership condition, which takes precedence over the general convention where it applies.
Where no such condition exists, agreeing the facing direction with a neighbour before building avoids a common and easily-avoided source of minor friction.
Smallholdings
A smallholding often needs several different boundary specifications on one plot — stock fencing for grazing paddocks, a more secure perimeter around poultry runs to keep foxes out, and a conventional garden fence around the house itself.
Movement of livestock between fields is usually managed with gates rather than continuous fence removal, so gate positions need agreeing against the smallholder's actual rotation pattern rather than simply the shortest route.
Because smallholdings often combine agricultural and residential use on the same title, it's worth checking which parts of a boundary project count as agricultural permitted development and which fall under the standard residential rules.
Dropped kerbs and boundary gate positions
A dropped kerb is authorised for a specific width and position, and a gate or fence opening that doesn't line up with it can create a technically unauthorised vehicle crossing over the footway.
Where a driveway gate is being repositioned or widened, it's worth checking whether the dropped kerb needs to be extended or moved to match, which is a separate application to the council's highways department.
Parking a vehicle over a kerb that hasn't been properly dropped, even briefly during works, can also draw attention from the local authority in some areas.
Discontinued panel styles
Panel fencing ranges get discontinued or reformulated by manufacturers more often than solid boarded fencing components, since panels are a proprietary product rather than built from generic stock timber sizes.
A ten- or fifteen-year-old panel range is often simply no longer made, which means a single damaged panel in an otherwise sound run may need the whole run replaced, or a mismatched panel accepted as a compromise.
Closeboard and picket fencing, built from standard boards, rails and posts rather than a proprietary panel, are generally easier to repair piecemeal decades later precisely because the components aren't tied to one manufacturer's product cycle.
Dog-proofing details at ground level and gaps
Dogs test a fence at ground level far more than at height, so gaps under gravel boards, worn hollows on sloping ground, or wide overlaps between adjacent panels are the points most likely to let a determined dog through or under.
A close-fitting concrete gravel board set with minimal gap to the ground, rather than a timber board that can warp and lift, closes off the most common escape route without changing the overall fence design.
For persistent diggers, a buried mesh apron or paving strip just inside the fence line at ground level stops excavation without needing to alter the visible fence at all.
Questions to ask any fencing contractor
Worth asking directly: who owns the boundary being worked on, what happens if buried obstructions are found, and whether waste removal and disposal are included in the price rather than charged separately afterwards.
It's also reasonable to ask what post-setting method will be used for the specific ground conditions on site, since a contractor who hasn't looked at soil type before quoting depth and concrete volume is guessing rather than specifying.
Asking how a contractor handles a shared boundary with a neighbour who hasn't been consulted is a good test of whether they've thought through the ownership question at all, rather than just the fence itself.
Boundaries adjoining registered common land
Land registered as common land under the Commons Registration Act carries specific legal protections, and fencing along a boundary with it can require consent from the Planning Inspectorate under separate legislation.
This is a different and more specialist process than an ordinary planning application, reflecting the protected status of common land itself.
Anyone with a boundary adjoining registered common land should check its status carefully before assuming a straightforward fence replacement is all that's needed.
