How we usually approach boundary and garden wall repairs

Dealing with roots and soil loading

Soil banked against the wall is dug back. Where roots are the cause, the wall can be rebuilt with a lintel bridging the root zone, or realigned to give the tree room. Decisions about the tree are made with its owner and, where needed, a tree specialist.

Best for: Walls lifted by roots or pushed over by banked soil

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.
Neighbour and notices
Where the wall is shared or on the line of junction in England and Wales, the Party Wall etc. Act 1996 may require notice before work starts. We can explain what is likely to be needed, and work is agreed with neighbours first.
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.

Questions about boundary and garden wall repairs in County Durham

Does the ground around Darlington cause cracking?

Much of County Durham sits on the Durham Coalfield, worked for centuries, often under a cover of glacial clay. Many former pit villages have recorded mine workings, and coal mining searches are standard for property here. Historic coal workings are recorded beneath parts of County Durham, and a coal mining search is worth checking where movement is unexplained. Only an investigation on site can say why a particular building has moved.

How much will boundary and garden wall repairs cost in County Durham?

On North East rates, boundary and garden wall repairs starts from about £275 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.

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.
