Is County Down prone to ground movement?
We cover Bangor and its postcode districts BT19, BT20, part of County Down, with a population of roughly 61,000. If you are just outside Bangor, we also cover Newtownards (5 miles), Holywood (6 miles) and Downpatrick (23 miles).
Clay shrinkage is less of a concern in County Down, so other causes such as drains, poor footings or older walls are checked first. Ground movement here is more often linked to soils, drains and trees than to mining. Across County Down, most homes are Victorian seaside houses in Bangor and Holywood, brick terraces and post-war estates.

Which repair method suits a home in Bangor?
Filling and repointing
For hairline and narrow cracks that have stopped moving, the crack line is raked out and repointed in mortar matched to the original for strength, colour and texture. Inside, plaster cracks are cut out, filled with a flexible filler and redecorated.
Best for: Cracks up to about 5 mm that are no longer moving
Crack stitching with helical bars
Stainless steel helical bars are grouted into slots cut along the bed joints, bridging the crack so the masonry works as one piece again. It is the standard repair for wider stepped and vertical cracks once whatever caused them has stopped.
Best for: Stable cracks wider than about 5 mm, or ones that keep reopening
What happens when we carry out structural crack repairs in Bangor?
Survey and record
On site we measure the width along the crack, note its pattern and check nearby drains, trees and openings. If the cause is unclear, gauges can be fixed across it and read over several months.
Deal with the cause
Leaking drains, failed ties, a sagging lintel or ground movement are put right first, sometimes through an insurance claim. Repairing a crack before its cause is fixed usually means paying for the same job twice.
Repair and make good
Cracks are stitched, repointed or rebuilt as specified, with mortar matched to the existing wall. Internal crack lines are filled and redecorated where included, and you get a written note of what was done.
Rules for structural crack repairs in Northern Ireland
In Northern Ireland, minor repairs usually need no approval, but structural work comes under the Building Regulations (Northern Ireland) 2012 and council building control. There is no Party Wall Act in Northern Ireland.
Structural crack repairs in Bangor: questions and answers
What is the price of structural crack repairs in Bangor?
Guide prices for structural crack repairs in Bangor start from about £70 per metre of crack, 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 carry out structural crack repairs in Bangor?
Yes, Bangor is covered, along with postcode districts BT19, BT20. We also cover nearby Newtownards and Holywood.
Does the ground around Bangor cause cracking?
County Down is mostly drumlin till over older rock and granite in the Mournes, with soft estuarine ground around Belfast Lough and Strangford. Only an investigation can say why a particular building has moved.
Are horizontal cracks in a wall serious?
Horizontal cracks are often more serious than vertical ones, because they suggest the wall is being pushed or lifted. Cracks repeating every few courses point to rusting wall ties, while one long crack with a bulge may mean lost restraint.
Should I tell my insurer about cracks in my house?
Yes, if you think the cracks could come from subsidence or heave, tell your insurer before any permanent repair, because repairing first can make a claim harder to prove. Cracks from normal shrinkage or ageing are not usually covered, and the insurer decides which applies.
