Is Merseyside prone to ground movement?
St Helens, Merseyside: about 180,000 residents across postcode districts WA9, WA10, WA11. Neighbouring towns we cover: Prescot (3 miles), Ashton-in-Makerfield (4 miles) and Huyton (5 miles).
Parts of Merseyside have clay that can shrink near trees in dry spells. Parts of Merseyside lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Merseyside: Victorian terraces and villas, inter-war council estates and post-war semis.

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?
Photos and ownership
Send photos of the whole wall and close-ups of cracks, the lean and the coping, plus any nearby trees. Tell us whether the wall is yours, shared or your neighbour’s, as that affects who can instruct the work.
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.
Repair and rebuild
Sections are taken down, footings dug, and the wall rebuilt or repointed with a damp-proof course and coping. Reclaimed or matched bricks keep the wall consistent, and spoil and old materials are removed at the end.
What to look for before calling about boundary and garden wall repairs
- Coping stones or brick-on-edge tops loose, cracked or missing
- Wall leaning towards the pavement, drive or neighbour’s garden
- Crumbling mortar, or bricks with faces flaking away
Rules for boundary and garden wall repairs in England
Like-for-like repairs such as crack stitching and repointing do not usually need building control approval in England, but anything that changes or strengthens the structure, such as underpinning or rebuilding a wall, does. If the work touches a party wall, the Party Wall etc. Act 1996 may apply.
Questions about boundary and garden wall repairs in St Helens
How much should I budget for boundary and garden wall repairs in St Helens?
Guide prices for boundary and garden wall repairs in St Helens start from about £290 per wall, including VAT, on North West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Why do houses in Merseyside crack?
Merseyside is mostly sandstone with glacial till on top, with soft coastal deposits in Sefton and the Lancashire coalfield extending under St Helens and parts of Knowsley. Old docks and industry left made ground in places. Only an investigation can say why a particular building has moved.
Who is responsible for a boundary wall?
Responsibility depends on who owns the wall, which is shown in your title deeds and plans, or may be shared. A wall built on the line between two properties is often jointly owned. Check the deeds first and agree repairs with your neighbour, and in England and Wales check whether the Party Wall Act applies.
Does the Party Wall Act apply to garden walls?
It can, in England and Wales. A boundary wall that stands astride the line of junction, used by both owners, can be a party fence wall under the Party Wall etc. Act 1996, and some work to it needs notice. A wall wholly on one side is not covered in the same way. Scotland and Northern Ireland have no Party Wall Act.
