Metal Fencing in Barnet: What Works on narrow rear gardens with mature trees and London clay underfoot

Steel earns its price in two places: it does not rot, and it can be made to an exact opening. For Barnet front boundaries and commercial lines we fabricate to survey, hot-dip galvanise, then powder-coat to a RAL colour. Capital Fencing installs metal fencing across Barnet and out to new barnet and potters bar. Barnet coverage plus proximity to M25 J23 (South Mimms) means most quotes are on your inbox within 48 hours of a site visit. Recent work on Salisbury Road and Gladsmuir Road. We orient jobs off The Spires.

Typical spec

How we build metal fencing in Barnet

Galvanised steel, powder-coated bar-and-rail or estate railings. Standard build: 1.8m bow-top or estate railings, 40mm SHS posts, concrete-set at 750mm. On Barnet jobs we adjust for shared-boundary disputes are common on the older terraced streets, so neat post lines and clear ownership marks matter.

Property mix locally: Victorian terraces, post-war semis and a band of larger Edwardian villas around Hadley Green. Typical gardens: narrow rear gardens with mature trees and London clay underfoot. Postcodes we regularly service: EN5, N20.

Metal Fencing FAQs — Barnet

How much clearance under the railings for a domestic front garden?

Bar spacing gets set to the use: closer for a Barnet frontage with young children, wider where the priority is the view through. We work this patch weekly, from Barnet High Street out toward new barnet. In short: structurally the toughest boundary material we install, though no privacy — this is a demarcation and security material, not a screen.

Can metal railings be installed on a low brick wall?

Bar spacing gets set to the use: closer for a Barnet frontage with young children, wider where the priority is the view through. For victorian terraces in EN5, that is where the cost sits. In short: structurally the toughest boundary material we install, though no privacy — this is a demarcation and security material, not a screen.

Are bow-top railings compliant for school and nursery use?

Bar spacing gets set to the use: closer for a Barnet frontage with young children, wider where the priority is the view through. We allow for narrow rear gardens with mature trees and London clay underfoot when setting out in Barnet. Worth weighing structurally the toughest boundary material we install against no privacy — this is a demarcation and security material, not a screen before you commit.

What's the lead time on made-to-measure railings?

Every fixing hole is drilled before galvanising, so nothing on a Barnet run exposes raw steel after fitting. Survey slots across EN5 are usually inside a week.

Before you book metal fencing in Barnet

Post fixing for a heavier double-skin panel

A double-skin acoustic panel is considerably heavier than a standard lap-panel fence, so the post and base spec has to be upgraded to carry that extra weight over the long term, not just at installation.

A post that's undersized for the load will lean within a couple of seasons, which opens gaps at the joints and undoes the sealed-joint principle the whole build depends on.

Overhanging roofline drip lines onto a boundary

A fence running close to a house or outbuilding without gutters, or with a gutter that overshoots during heavy rain, can sit directly under a concentrated drip line that soaks one section of the run far more than the rest.

Over time this shows up as a localised patch of accelerated rot or algae growth that doesn't match the general weathering pattern of the rest of the boundary.

Where this can't be resolved by fixing the guttering itself, a slightly increased offset from the wall or a more resistant board section at that specific point avoids repeat localised failure.

Corner plots and highway sightlines

A boundary fronting a road used by vehicles is limited to 1m under permitted development, but corner plots have a second constraint: the highway authority's visibility splay, which can require even lower boundary treatment near a junction so drivers can see pedestrians and oncoming traffic.

These splays are measured as a triangle from a set point back along both roads and are sometimes fixed by a planning condition on the original build rather than by the general permitted development rules.

A solid fence built to the letter of the 1m rule can still be a highway safety problem on a tight corner, so it's worth checking the local plan or asking planning before finalising height on a corner boundary.

Salt and de-icing near a pavement

A front boundary fence close to a pavement or road gritted in winter is exposed to salt spray and run-off that a rear-garden fence never sees, and that salt accelerates corrosion in untreated steel fixings and speeds up timber degradation at ground level.

Galvanised or stainless fixings resist this better than standard bright steel, and are worth specifying as standard on any boundary within a few metres of a regularly gritted surface.

Salt-laden ground also tends to stay damp for longer after a thaw, extending the period a post base is sitting in wet conditions each winter.

Drilling into engineering brick or dense blockwork

Engineering brick and dense concrete block are far harder than ordinary facing brick, so standard masonry drill bits blunt quickly and a hammer-action drill with a carbide-tipped bit designed for dense material is needed to make progress without excessive heat.

Drilling slowly with intermittent withdrawal to clear dust keeps the bit cooler and the hole cleaner than forcing continuous pressure, which tends to glaze the hole and reduce the fixing's grip.

Where a wall is engineering brick specifically because it's load-bearing or below damp-proof course, it's worth checking that the fixing depth and pattern doesn't compromise the wall's structural role before drilling a run of holes into it.

Protecting a shared alley during material delivery

A shared rear alley used by several households for bin access can't be blocked completely for a full day without agreement, so materials are often moved through in stages between other residents' access needs rather than left stacked across the full width.

Trailing cables, tools and offcuts left in a shared passage are a trip hazard for neighbours as well as the crew, so keeping the alley clear at the end of each working day matters even if the job isn't finished.

Any damage to the alley surface itself — cracked paving, a scraped wall corner from a wide panel — is worth flagging to the client immediately, since a shared area often has joint liability that's harder to unpick after the event.

Checking which face of a panel should face outward

Many panel styles have a clear 'good' face with a neater finish and a reverse face showing the frame, battens or rail ends, and getting this the wrong way round means the less tidy side ends up facing the client's own garden or the neighbour's, depending on convention and agreement.

Where a boundary is shared, it's worth agreeing in advance which side the good face should present, since local convention varies and assuming it defaults toward the neighbour without discussion can cause an avoidable dispute.

Checking panel orientation before fixing, rather than after several panels are already up, saves having to unfix and turn a run of panels that all went in the wrong way round.

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.

Sequencing a fence alongside window replacement works

Where both a boundary barrier and window upgrades are planned, doing the fence first can mean a temporary improvement is felt sooner, while doing the windows first addresses noise transmission through the fabric that a fence never reaches.

There's no single correct order, but agreeing it in advance based on which noise path is currently causing the most disturbance avoids spending on one improvement before establishing whether the other would have mattered more.

Seasonal restrictions on hedge and vegetation clearance

Clearing vegetation or a hedge to make way for a fence during bird nesting season, broadly March to August, risks disturbing an active nest, which is a wildlife offence regardless of whether the fencing work itself is otherwise unrestricted.

A quick visual check for active nests before cutting back growth is standard practice, and where a nest is found the sensible step is working around it rather than pushing ahead with clearance.

Outside nesting season, most routine hedge cutting ahead of fencing work has no seasonal restriction, though thicker or more established hedgerows may still need the checks covered elsewhere for protected hedgerows.

What aftercare actually covers

A written warranty on fencing, gates or decking should say clearly what's covered — usually workmanship and post stability — versus what naturally weathers over time, like colour fade or minor timber checking, which isn't a defect.

It's worth asking what happens if a panel is damaged by a storm or a fallen branch, since that's typically outside a workmanship warranty and may be a buildings insurance matter instead.

Keeping the original quote, spec sheet and any photos from the day of installation makes any future warranty conversation faster, since it confirms exactly what was fitted and to what standard.

Motorcycle pass-by noise

A motorcycle, particularly one with an aftermarket exhaust, can produce a sharp acceleration noise significantly louder than a typical car at the same speed, and that noise is heavily directional, projecting rearward from the exhaust.

On a road with mixed traffic, isolated motorcycle pass-bys will remain audible above a barrier even where general traffic noise is well controlled, since a single loud event can exceed what a barrier's average attenuation covers.

Boundary work near underpinning or subsidence repairs

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.

Hot-dip galvanising thickness

Hot-dip galvanising coats steel in a layer of zinc by immersing it in a molten zinc bath, and the resulting coating thickness is largely governed by the steel's own thickness, since thicker sections react with the zinc for longer and build a heavier layer.

British Standard BS EN ISO 1461 sets minimum coating thickness by section thickness rather than a single blanket figure, which is why a heavy structural post gains a thicker, longer-lasting coating than thin wire mesh galvanised in the same process.

The coating protects sacrificially as well as by barrier, meaning even where it's scratched the surrounding zinc corrodes preferentially and continues to protect the exposed steel underneath, at least until that local zinc reserve is used up.

Steel is the long-life option: concrete-set posts, hot-dip galvanised frames, and a colour that can be re-coated rather than replaced across EN5, N20. Metal Fencing across EN5, N20 is one of our regular runs.
