How we usually approach boundary and garden wall repairs
Rebuilding a leaning section
The leaning or badly cracked section is taken down, sound bricks cleaned for reuse, and the wall rebuilt on a new footing at a suitable depth. A damp-proof course and a proper coping are added, and the new work is jointed to the sound wall either side.
Best for: Sections that lean, rock or have cracked right through
New piers and movement joints
Brick piers are built at intervals along the wall, bonded in or tied with stainless fixings, to stiffen it against wind and lean. Vertical movement joints are cut where a long run keeps cracking. Gate piers are rebuilt larger and on deeper footings where they carry heavy gates.
Best for: Long walls with regular cracks, or weak gate piers
What happens during boundary and garden wall repairs, step by step?
Site assessment
On site we check the lean with a level, look at the footing where it can be seen, note the bricks and mortar, and check for trees, soil loading and gate loads. If the wall turns out to be retaining soil, we treat it as a retaining wall.
Written quote
You receive a no-obligation written quote that separates repointing, rebuilt sections, new piers and copings, so you or your neighbour can see each part. It becomes a fixed price in writing once the repair is specified.

Why do houses in West Sussex crack?
North West Sussex around Crawley and Horsham sits on Weald Clay, the South Downs are chalk, and the coastal plain has brickearth and gravels. The Weald Clay is prone to shrink-swell movement near trees. Only an investigation can say why a particular building has moved.
Is a leaning garden wall dangerous?
It can be, particularly a tall wall, a front wall by a pavement or one that moves when pushed. A slight lean that has not changed for years may be stable, but a wall leaning more each year should be kept clear and repaired before a storm finds it.
Does home insurance cover a fallen garden wall?
Sometimes, but many policies exclude garden walls or cover them only for certain events, such as vehicle impact or storm. Frost, wear and tree root damage are usually excluded. If a vehicle caused the damage, the driver’s insurer may pay. Check your policy and tell your insurer before permanent repairs start.
