Boundary and garden wall repairs in Belfast
Where older streets in Belfast and across County Antrim keep their original brick front walls, those walls often sit on shallow footings with soft lime mortar. Matching the bricks and mortar matters as much as the repair itself if the wall is to look right afterwards.

Is County Antrim prone to ground movement?
Belfast is in County Antrim and takes in postcode districts BT1, BT2, BT7. About 350,000 people live there. We also take enquiries from nearby Newtownabbey (4 miles), Lisburn (7 miles) and Carrickfergus (10 miles).
Most of County Antrim is on firmer ground than the clay belts of the south-east. Historic brine and salt working has caused ground movement in parts of County Antrim in the past. Housing stock in County Antrim: Red-brick terraces in Belfast, Victorian villas, and post-war and newer estates.

Methods for boundary and garden wall repairs
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
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

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.
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.

Frequently asked questions
How much will boundary and garden wall repairs cost in Belfast?
Guide prices for boundary and garden wall repairs in Belfast start from about £265 per wall, including VAT, on Northern Ireland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Belfast?
Yes, Belfast is covered, along with postcode districts BT1, BT2, BT7. We also cover nearby Newtownabbey and Lisburn.
Is the ground in County Antrim prone to subsidence?
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. Only an investigation can say why a particular building has moved.
Do I need permission to rebuild a front wall?
Usually not for a like-for-like rebuild. Building a front wall next to a road higher than the permitted height, or work in a conservation area or to a listed building, can need planning consent. Check with your council before changing a wall’s height or appearance.
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.
