Why does the ground in Merseyside matter for boundary and garden wall repairs?

Parts of Merseyside lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Merseyside, most homes are Victorian terraces and villas, inter-war council estates and post-war semis.

Repair options we may recommend

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

Repointing and minor repairs

Weak mortar is raked out and the wall repointed in a mortar that suits the bricks, and damaged bricks are replaced with matching ones. Loose copings are rebedded or replaced with a design that throws water clear of both faces. This is often enough for an upright wall.

Best for: Upright walls with weathered joints, loose copings or spalled bricks

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

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.

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.

Your boundary and garden wall repairs questions

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. Parts of Merseyside lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.

How much will boundary and garden wall repairs cost in Merseyside?

On North West rates, boundary and garden wall repairs starts from about £290 per wall, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.

Can tree roots damage a garden wall?

Yes, they often do. Roots can lift footings, push walls sideways and, on clay soils, dry the ground so it shrinks under the wall. A wall can sometimes be rebuilt to bridge roots. Take advice before removing a large tree, as it may be protected and removal on clay can cause heave.

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.

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.
