Barnet Council is the local authority for Barnet (EN5, N20); the housing stock leans toward victorian terraces, post-war semis and a band of larger edwardian villas around hadley green, and gardens tend to be narrow rear gardens with mature trees and london clay underfoot. What tends to drive the spec on a Barnet job is shared-boundary disputes are common on the older terraced streets, so neat post lines and clear ownership marks matter. Coordinating fencing work with other trades on a shared site: On a job where fencing follows landscaping, paving or groundworks by another trade, confirming final levels and boundary positions with that other trade before digging starts avoids fence posts being set to a level that then changes once the remaining groundwork is finished. Where fencing is scheduled before paving, agreeing which side of the post line the paving will finish against prevents a post ending up embedded in what should have been a clear paving joint. Realistic maintenance intervals: Pressure-treated softwood fencing generally wants a re-application of preservative or stain every two to three years to keep the surface protected, more often on a south-facing run that gets constant UV exposure.

Under Barnet Council, covering EN5, N20. Nearest arterial: A1000 Great North Road, M25 J23 (South Mimms). Served from High Barnet (Northern line). Local commercial anchors: Barnet High Street, Stirling Way industrial estate.
Streets we regularly work on: Kings Road, Salisbury Road, Gladsmuir Road, Wood Street. Local anchors: High Barnet station, The Spires, Chipping Barnet churchyard.
Hadley Green Conservation Area constrains front-boundary heights and materials, with painted picket or low brick-and-rail typical of the streetscape. The Victorian terraces off Wood Street back onto mature street trees protected by the council. Chipping Barnet's medieval plot lines mean the town's boundaries are rarely square, a legacy of the original burgage plots. Kings Road drops steeply toward the East Coast Main Line, and the gradient there is a well-known feature of the local topography.
Practical points for boundary work in Barnet
Coordinating fencing work with other trades on a shared site
On a job where fencing follows landscaping, paving or groundworks by another trade, confirming final levels and boundary positions with that other trade before digging starts avoids fence posts being set to a level that then changes once the remaining groundwork is finished.
Where fencing is scheduled before paving, agreeing which side of the post line the paving will finish against prevents a post ending up embedded in what should have been a clear paving joint.
Simple sequencing conversations at the outset, rather than each trade working to its own assumptions, avoid the more expensive alternative of one trade's finished work being disturbed by the next.
Realistic maintenance intervals
Pressure-treated softwood fencing generally wants a re-application of preservative or stain every two to three years to keep the surface protected, more often on a south-facing run that gets constant UV exposure.
Gate hinges and latches are worth checking annually for movement or corrosion, since a small adjustment caught early avoids the gate racking out of square and needing a rebuild.
Decking boards benefit from a yearly clean to clear leaf litter and algae from the gaps, which is what actually causes most of the slipperiness people blame on the timber itself.
Aluminium and steel railings
Aluminium railings are lighter, don't rust, and hold a powder-coated finish well without the ongoing maintenance steel needs, which makes them common for low-boundary and pool-safety railings where upkeep is meant to be minimal.
Steel railings are heavier and stiffer for the same section size, which suits taller or higher-security applications, but the finish has to be maintained — a scratch through galvanising or powder coating exposes bare steel to rust from that point.
Both are usually supplied as welded panels between posts rather than built up rail-by-rail on site, so panel width and post spacing need to be agreed before ordering rather than adjusted afterward.
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.
Composite thermal expansion
Wood-plastic composite boards expand and contract with temperature considerably more than solid timber, since the polymer content responds more to heat than wood fibre does on its own.
Manufacturers specify a mandatory expansion gap at both board ends and between boards laid end to end, and skipping that gap during installation is one of the most common causes of composite decking or fencing buckling in hot weather.
Dark-coloured composite absorbs more solar heat than lighter shades and expands correspondingly more, so the expansion allowance recommended for a dark board is often greater than for a pale one of the same profile.
Checking cumulative ground level change along a long boundary
A gentle, barely perceptible slope checked only between adjacent posts can still add up to a substantial total fall over a long boundary, which is easy to miss without measuring from a single fixed datum along the whole run.
Taking level readings from one datum point at both ends and at intervals along the run, rather than only comparing each post to its immediate neighbour, reveals the true overall fall before panel and post heights are finalised.
This matters most for ordering materials in advance, since a run that turns out to need more steps or a longer rake than first estimated can mean extra cut panels or capping that weren't in the original take-off.

What's the typical garden like in Barnet?
Narrow rear gardens with mature trees and London clay underfoot is typical, alongside victorian terraces, post-war semis and a band of larger edwardian villas around hadley green.
Is Barnet within your standard travel area?
Yes — Barnet is served from High Barnet (Northern line), off A1000 Great North Road, and is inside our regular working patch.
