New-Build Garden Fencing — What We Actually Build
New-build garden fencing is an upgrade brief. The developer's minimum-spec boundary — usually 4ft overlap panels on thin posts — is built to last through snagging, not through a decade of London weather, and most owners find that out within four winters.
This is regular work for us across new estates in North London and Hertfordshire, replacing developer fencing with something that's actually meant to last.
Why the developer spec fails first
It's almost always the posts, not the panels. Thin timber posts on a shallow set are the part that goes first — putting new panels on the same posts just repeats the failure.
- 6ft closeboard on concrete posts, 150mm gravel boards, mid-rail capped
- Trellis-top extensions where permitted development height allows
- New posts, not new panels on old posts
Working around plot pegs and drainage
New-build gardens hide plot-boundary pegs and drainage runs that a standard measure-up can miss — we check for both before any post goes in the ground.
Shared boundaries and snagging periods
Raising or replacing a shared boundary needs the neighbour's agreement, and estates still inside a developer snagging period may have the boundary as the developer's liability, not yours — we'll flag both before quoting.
New-Build Garden Fencing — frequently asked
Can I replace the developer's fence in the first two years?
You can, but check your snagging period first — the developer may be liable to fix it rather than you needing to pay for a replacement.
Why do developer fences fail so quickly?
Usually the posts — thin timber, shallow set. New panels on old posts just repeat the same failure.
Can new panels be fitted to existing developer posts?
We generally don't recommend it — the posts are usually the weak point, so replacing both is the properly durable answer.
Do I need permission to raise a new-build boundary?
Sometimes, and Section 106 covenants on some estates restrict boundary appearance — worth checking your deeds first.
Do you handle the neighbour conversation on a shared boundary?
We can, but the agreement itself needs to come from you and your neighbour — we'll help with the practical detail.
