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
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

Questions about boundary and garden wall repairs in County Antrim
Does the ground around Belfast cause cracking?
County Antrim is largely basalt over chalk, with soft estuarine 'sleech' along Belfast Lough that is notorious for settlement. Historic salt mining is recorded near Carrickfergus. Historic brine and salt working has caused ground movement in parts of County Antrim in the past. Only an investigation on site can say why a particular building has moved.
How much will boundary and garden wall repairs cost in County Antrim?
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.
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.
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.
Can a leaning wall be pushed back upright?
Usually not in a way that lasts. Masonry does not bend back, and forcing a wall upright tends to crack it further. The normal repair is to rebuild the leaning section on a proper footing, reusing sound bricks, and add piers to stop it happening again.
