Hot Tub Decking in Finchley is a specific brief for us — homeowners installing a hot tub who need the deck sized to carry the loaded weight. The default local answer isn't a stock catalogue drop: it's 150×47mm C24 joists at 300mm centres over doubled bearers under the tub footprint; hot-tub area calculated to 400kg/m² loaded. On Finchley sites we also spec around tree-root activity in clay soil regularly lifts old fence runs — full re-set is the typical brief, which is where a lot of hot-tub decking jobs quietly fail two years in. Roads such as Ballards Lane and East End Road are typical of the local layout. Church End library is a useful local reference point. The Church End Conservation Area covers much of the historic centre around Avenue House.

For context: grooved composite boards keep grip when wet — the whole point of a hot-tub deck surface. Hardwood and composite specified to genuine service-life numbers.
Across Finchley we spec around tree-root activity in clay soil regularly lifts old fence runs — full re-set is the typical brief, so on hot-tub decking that usually means Trex or Q-Deck composite for a wet, chlorinated environment. We'll walk you through joist spacing and bearer doubling sized to the loaded tub weight, not a generic domestic spec on the site visit before you commit.

A repair to a single post or panel deep in a rear garden with no side access still needs materials and tools carried through rather than dropped at the boundary, which is worth factoring into the timeline on a tight terraced plot.
On a multi-property repair — several gardens sharing a rear boundary — coordinating access across neighbours can be the more awkward part of the job than the repair itself.
Where a fence line crosses from a garden onto a patio, driveway or other hardstanding, post bases usually need core-drilling into the existing slab rather than a dug hole, which is a different technique and a different price than fencing over soil.
A change in level along a run — a step up to a raised patio, or a drop to a lower side passage — needs the fence height measured consistently from the ground it's actually protecting, not from an average across the whole run.
Getting this detail wrong is one of the more common reasons a finished fence ends up looking uneven even though every panel was fitted correctly on its own section.
A two-rail configuration (top and bottom) suits lower runs, while anything above around 2.4m generally takes a third, mid-height rail to stop the pales flexing independently under a push or climb attempt.
Rail spacing is set so a gap doesn't become a foothold; on a taller run the middle rail is positioned deliberately off-centre rather than dead-centre, to avoid creating an even climbing ladder.
A gate that's also the main delivery route needs wider clearances and a more robust hinge and closer than a purely pedestrian gate, because it will be opened and knocked far more often.
Where an intercom or access-control system is fitted, the fencing contractor coordinates gate width and swing with the installer of that system rather than fixing the gate first and adapting the electronics afterwards.
On a longer run with more than one person digging simultaneously, working from both ends toward the middle rather than each person working independently along the same stretch reduces the risk of small setting-out errors compounding in the middle of the run.
Whoever sets out the string line and corner points needs to communicate any adjustment immediately to everyone digging, since a post dug to an outdated mark before a correction is passed on means redoing that hole.
Checking in at the midpoint, where the two ends meet, catches any accumulated drift before panels are ordered or cut to a spacing that assumed the line stayed perfectly true throughout.
Where a boundary fence sits directly above a basement lightwell, sunken patio, or retaining wall with a significant drop on one side, the fence effectively doubles as a safety barrier and needs a height and gap specification suited to that fall risk rather than a standard garden boundary spec.
Post fixings in this situation often need to tie into the retaining structure itself rather than a simple ground-set post, which is a different engineering detail to a standard concrete-in post.
This is worth identifying clearly at survey stage, since treating it as a routine fence replacement without accounting for the drop below is a genuine safety oversight.
A timber gate that's greying or losing its finish benefits from a light sand back to bare or sound timber before re-treating, since coating over a failed or flaking existing finish traps moisture underneath rather than sealing it out.
This is worth doing every few years depending on exposure, well before the timber itself starts to soften or split.
A gravel board sitting flush with the soil on one section of a run can end up buried a couple of inches by the time the ground rises further along an uneven boundary, trapping moisture against timber that was specified to sit clear of the soil.
Stepping the board height slightly at each post, rather than running one continuous level line, keeps a consistent clearance above grade along the whole run.
Concrete gravel boards tolerate this ground contact better than timber ones, which is one reason they're specified as standard on plots with visibly uneven levels.
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.
A property that's had underpinning or subsidence repair work sometimes has ground disturbance extending into the garden near the boundary, which can affect where a new fence line can safely be dug without disturbing settled ground.
Where underpinning is recent, it's worth checking with whoever carried out the structural work before digging post holes nearby, since the settlement process can continue for some time after the visible repair is finished.
Cracking in an existing boundary wall running close to a subsidence-affected building is sometimes an early symptom worth reporting rather than just repairing cosmetically.
Post-hole augering, breaking out old concrete footings and cutting steel palisade to length all generate noise that's worth flagging to neighbours or site occupants in advance, particularly on a compound or commercial job with fixed working hours nearby.
Where a site has noise-sensitive neighbours, sequencing louder tasks earlier in the working day and confining cutting to one area reduces the disruption without slowing the job significantly.
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.
Some driveways, particularly on corner plots or busier roads, are subject to a required visibility splay — an area kept clear of tall obstructions so drivers can see pedestrians and other vehicles safely.
A fence built to the usual permitted development height can still breach a specific visibility splay condition attached to the property, especially where one was imposed when the driveway was originally created.
Checking historic planning conditions for the property, or asking the council's highways team, is worth doing before fencing close to any vehicle crossing.
Capped composite boards have a thin outer polymer shell bonded over the wood-polymer core, giving better resistance to moisture ingress, staining and UV fade than an uncapped board with the core material exposed directly to weather.
Uncapped composite is generally cheaper and machines more like traditional timber, since the surface can be cut, drilled or profiled without exposing a different material underneath, but it's more prone to surface fading and moisture absorption over time.
A capped board's protective shell is only on the finished faces, so a cut end on site exposes the uncapped core underneath, which some manufacturers address with an end-cap trim while others leave it exposed.
A drop bolt fixed to the bottom rail of a leaf drops into a ground socket to hold that leaf still while the other leaf is used for daily access, and a socket that's silted up or out of alignment is a common reason a drop bolt stops locating properly.
We check the socket depth and drainage as well as the bolt itself, since a blocked socket is often mistaken for a bent or worn bolt.
Before a gate is automated, its weight, swing clearance and frame rigidity need to suit the motor type being considered, and a gate that's sound for manual use isn't automatically suitable for automation without checking.
We check the gate itself is fit for automation and refer the motor, control-board and sensor installation to a specialist automation engineer.
FSC and PEFC certification track timber back through the supply chain to a managed, legally-harvested source, and UK public sector specifications increasingly require one or the other for any structural or landscaping timber.
For a domestic fence this isn't a legal requirement, but certified stock gives a paper trail on sourcing that some clients specifically ask for, particularly on larger commercial or estate contracts where corporate sustainability policy applies.
Certification is about the chain of custody rather than the treatment or grade of the wood, so it sits alongside, not instead of, checking the timber is correctly treated for its intended use class.
A post cap sheds water off the end grain of a timber post or the open top of a hollow steel post, but on a security run it also removes a foothold or handhold that an open post top would otherwise offer.
Domed or sloped caps are harder to grip than a flat cap, which is worth specifying on posts near a gate or corner where climbing is most likely to be attempted.
A board that splits at a nail has usually been fixed too close to its edge or fixed with the nail driven into an existing check in the grain, and the split then runs further with each wet-dry cycle until the board finally lets go.
Repair is either refixing with screws set further from the edge and pre-drilled to avoid a repeat split, or replacing the board outright where the split has already reached the board's full width.
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.
Where a security upgrade only covers part of a boundary, the new section is matched to the existing line's height and topping detail so the boundary reads as one continuous deterrent rather than a strong section next to an obviously weaker one.
On a shared commercial perimeter this often means checking a neighbouring occupier's existing spec before finalising the new section.
A dog that digs at the base of a fence or chews at exposed board edges tends to concentrate damage at one recurring spot rather than spreading it along the whole run, which makes a localised repair — a buried mesh skirt, a metal kick-plate — more effective than a general fence upgrade.
Addressing the underlying cause, such as blocking the specific gap the dog is trying to reach through, matters as much as the physical repair, since a repaired section without that change is often damaged again in the same place.
