How we usually approach boundary and garden wall repairs
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
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
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.
What to look for before calling about boundary and garden wall repairs
- A tree close to the wall, with the base lifted or cracked

Questions about boundary and garden wall repairs in County Down
Why do houses in County Down crack?
County Down is mostly drumlin till over older rock and granite in the Mournes, with soft estuarine ground around Belfast Lough and Strangford. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.
How much will boundary and garden wall repairs cost in County Down?
On Northern Ireland rates, boundary and garden wall repairs starts from about £265 per wall, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
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.
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.
