How a security survey is carried out
A security survey walks the whole perimeter, not just the section that prompted the enquiry — low runs, blind corners and gate junctions elsewhere on the boundary are usually the actual weak point, even when the call came in about one obviously damaged section.
We note sightlines from the street and from within the property, because a fence that blocks a view outward can work against security as easily as a low fence works against it from the other side.
Wind loading on exposed runs
A fence on an open, elevated or unsheltered boundary — a plateau, a field edge, or a long unbroken run with no buildings breaking the wind — takes a real structural load that a sheltered suburban garden never sees.
Standard 75x75mm posts and full-height solid panels are the combination most likely to fail here; heavier posts, shorter bays between them, and a slatted or louvred profile that lets some wind through all reduce the load rather than fighting it head-on.
It's a specification decision made at quote stage, not something to retrofit after the first panel goes over in a storm.
Working around pets and children on site
An open trench, a stack of loose posts or a partially removed fence panel is an obvious hazard for a young child or an excitable dog, and on an occupied family garden it's worth agreeing at survey stage how pets will be kept away from the working area each day.
A garden with no boundary at all for part of a working day — because the old fence has come down and the new one isn't up yet — needs a temporary barrier or a clear arrangement for keeping animals indoors until the run is complete.
Leaving tools, concrete mix or offcuts accessible overnight on a site with children present is worth avoiding even where the work itself is finished for the day.
Upgrading security at a farm gateway
A farm gateway is a common target for rural theft of machinery, fuel and livestock, and a five-bar field gate on its own offers little more than a visual boundary marker, so a security upgrade typically adds a padlockable hasp, a stronger hinge set and sometimes a second inner gate as a layered deterrent.
Positioning a gate slightly back from the road with a locked field gate behind an open highway gate can slow a vehicle-based theft attempt without obstructing the farmer's own daily access.
Choosing rail section size for a security run
Rails on a palisade or railing run are sized in cross-section to the span between posts, not to the pale height alone, because a rail that's too slender for its span will visibly deflect under a leaning or pushing load.
A heavier box-section or channel rail is specified on wider bays or taller runs, and increasing bay width to save on posts only works if the rail section is upsized to match the extra span.
Checking post plumb tolerance after installation
A post that's slightly off plumb when first set can be adjusted while the concrete is still workable, but once cured the only fix is breaking out and resetting it, so plumb is checked with a spirit level in two directions before the pour rather than assumed from a quick visual check.
A run of posts each slightly off plumb in the same direction is usually a sign of a systematic setting-out error rather than individual mistakes, and is worth catching after the first two or three posts rather than the whole run.
Algae growth on north-facing panels
A boundary that faces north, or sits in the permanent shade of a tall building or dense hedge, stays damp for far longer after rain than a south-facing run, which is exactly the condition green algae needs to establish.
Algae on timber is mostly cosmetic in the early stages but makes the surface noticeably slippery, which matters where a fence line doubles as an informal foothold near steps or a sloped path.
A dilute biocidal wash applied before restaining is more effective long-term than staining directly over algae, which simply seals damp organic growth beneath the new coating.
Recommended inspection intervals for gate hardware
Checking hinge fixings, latch alignment and post plumb roughly twice a year, typically before and after the worst of winter weather, catches most developing faults while they're still a simple adjustment rather than a full repair.
A gate in heavy daily use, such as a bin store or communal alley gate, benefits from more frequent checks than a garden gate opened only occasionally.
Checking the repair before signing off
Once a repair is finished we open and close the gate repeatedly to check it swings cleanly and latches first time, since a gate that only closes properly on the first attempt in calm conditions can still catch once it's windy or the ground has moved slightly.
We also check the diagonal brace, where fitted, is taking the load evenly rather than pulling to one side.
Handling scope changes discovered once a repair is underway
A repair quoted from an initial inspection sometimes turns out larger once work starts — a post probed as sound at the surface but soft further down, or a neighbouring post found to be equally close to failure.
Agreeing a clear process for confirming any change in scope with the client before continuing, rather than proceeding on assumption, avoids disputes about what was and wasn't included in the original repair.
Fall direction and drainage across a deck
A deck built dead level holds standing water after rain, which speeds up algae growth and softens the timber surface faster than a deck with a slight fall built in to shed water away from the house.
The fall is normally built into the joist or bearer heights during construction, angled away from any adjoining wall or door threshold, rather than relying on the boards themselves to slope.
Getting the fall direction right at the design stage also avoids water pooling against a house wall, which risks damp ingress at the threshold over time.
Dealing with buried debris uncovered while digging out a repair footing
Old post stubs, broken glass, hardcore or builder's rubble from a previous era of the garden's use sometimes turn up when digging out a footing for repair, particularly on older plots that have been through several changes of use.
Where this happens, it's worth clearing enough of the obstruction to get a clean footing rather than working around it, and flagging anything unexpected — old drainage, buried cabling, unusually large rubble — to the client before continuing.
Wicket gates set within a larger gate
A wicket gate is a small pedestrian door built into one leaf of a larger vehicle gate, allowing foot access without opening the whole gate, and it needs its own hinge, latch and frame within the host leaf.
Because it's a frame within a frame, movement in the main gate can throw the wicket's alignment out even when the wicket's own hardware is sound, so both are checked together.
Composite versus timber
Composite decking and fencing boards trade a higher upfront cost for lower ongoing maintenance — no annual staining or oiling, and better resistance to rot in permanently damp or shaded spots where timber struggles.
The trade-off is that composite doesn't weather the way timber does; it stays close to its original colour rather than silvering or taking on the character some clients want, and off-cuts and end sections need cutting and capping carefully to stop moisture getting into the core.
For a boundary fence that's mostly out of sight, timber with a reapplied treatment every few years is often the more economical long-term choice; for a heavily-used deck, composite's lower maintenance burden usually wins out.
Recycled mixed-plastic lumber composition
Recycled plastic lumber differs from wood-plastic composite in that it's typically made entirely from reprocessed plastic waste with no wood fibre content, giving it complete immunity to rot and insect attack but a distinctly plastic rather than timber-like appearance.
Because it contains no wood fibre, it doesn't absorb moisture in the way composite or timber boards do, but it's also generally more flexible and prone to visible sagging over a wide unsupported span unless internally reinforced.
It's more commonly specified for ground-contact components like gravel boards and low retaining edges, where rot resistance matters most, than for larger structural fencing elements.
Post spacing on a run that doesn't divide evenly
Standard panels are usually 1.83m (6ft) wide, but very few boundary runs measure out as an exact multiple of that, so the layout has to absorb the remainder somewhere rather than pretend it isn't there.
The common approach is to split the shortfall across the two end bays so both are cut slightly narrower and roughly matched, rather than leaving one full-width bay and one very narrow offcut at a single end.
Where a fixed feature — a gate opening, a manhole, an existing post that must stay — sits partway along the run, setting out works outward from that fixed point in both directions rather than from one end only.
Diagonal measurement when squaring an opening
Measuring both diagonals of a gate opening before ordering or building a gate confirms whether the opening is actually square, since two openings with identical width and height measurements can still be out of square if the diagonals differ.
Building a gate to fit a supposedly square opening that isn't leaves a visible wedge-shaped gap that no amount of hinge adjustment can fully correct.
Replacing a concrete gravel board that has crumbled
A concrete gravel board crumbling at one end usually points to a spalled or corroded reinforcing wire near a corner or a slot where standing water has sat against it longest, rather than a fault along its whole length.
Because concrete gravel boards slot into the posts, a single damaged board is normally lifted and swapped without disturbing the panel above, provided the slot itself hasn't also broken away.
Fence panels built around a recessed bin store
A bin store built into or against a fence line needs its own ventilation gaps, since enclosed bin storage without airflow concentrates moisture and odour against the adjoining fence panels far more than open storage would.
The panel section forming the back or side of a bin store also takes more direct contact wear — bins being wheeled in and out, lids catching the timber — than the rest of the run, so a slightly more robust board or a protective kick panel at the contact height extends its life.
These wear patterns are worth designing for at the outset rather than treating the bin store section as identical to the rest of the boundary run.
Running bamboo and rhizome pressure on boundaries
Running bamboo species spread through underground rhizomes that can travel several metres from the parent plant and push up through gravel boards, path joints or even through weak points in a fence base.
Unlike tree roots, rhizome growth is fast and can reappear within a single growing season after being cut back, so a fence base alone rarely stops it without a physical rhizome barrier buried alongside it.
Where established running bamboo sits on a neighbouring boundary, it's worth flagging to the client that fence replacement won't solve the underlying spread on its own.
The general boundaries rule explained
Land Registry title plans in England and Wales normally show only the 'general boundary' of a property, meaning the line on the plan is indicative rather than a precise, surveyed measurement to the centimetre.
That's why a title plan alone rarely settles an argument about whether a fence sits a few inches one way or the other.
For most domestic fencing this doesn't matter, but where a dispute is brewing it's worth knowing the plan wasn't drawn to resolve exactly that kind of question.
Sizing a hinge post to the gate's actual weight
A hinge post needs to be sized to the specific gate it will carry, since a heavy solid timber or metal gate loads its post far more than a lightweight picket gate of the same height, and an undersized post will lean over time even if correctly concreted.
This sizing decision is best made before the post goes in, since upsizing a post after a lean has developed generally means digging it out and starting again.
