Subsidence repairs in Dungannon
Seasonal movement is behind a lot of subsidence, and once its cause is clear it is usually manageable for a home in Dungannon as much as anywhere. The repair that follows is mostly crack stitching, repointing and replastering, with foundation work kept for houses that need it.

Is County Tyrone prone to ground movement?
With roughly 12,000 people, Dungannon spans postcode districts BT71 in County Tyrone. Nearby, we also cover Cookstown (10 miles), Armagh (11 miles) and Portadown (14 miles).
Clay shrinkage is less of a concern in County Tyrone, so other causes such as drains, poor footings or older walls are checked first. Parts of County Tyrone lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across County Tyrone: market-town terraces, rural houses and post-war estates.
Methods for subsidence repairs
Remove the cause, then repair
Most subsidence is dealt with this way. The drain is repaired or the vegetation managed, the house is watched to confirm it has stabilised, and then the cracks are stitched, repointed and made good inside. It is the least disruptive route and usually the cheapest.
Best for: Clay movement or drain leaks where the cause can be removed
Crack stitching and making good
Once movement has stopped, cracked brickwork is cut along the bed joints, stainless helical bars are bonded in to tie the wall together, and the joints are repointed to match. Inside, plaster is renewed along the crack line before redecoration.
Best for: Category 1 to 3 cracking in walls that are otherwise sound
From first photo to finished repair
Send photos or call
Send photos of the cracks with a coin or tape for scale, and say when you first noticed them. We give a free initial assessment and suggest whether an engineer, a drain survey or your insurer comes first.
Find the cause
An independent chartered structural engineer inspects the house and, where needed, arranges a drain survey, trial pits or soil tests. We can arrange the engineer. The aim is to know what is moving, and why, before money goes on repairs.
Deal with the cause
Drains are repaired, vegetation is managed on the engineer’s advice, or a foundation scheme is designed if nothing else will work. Where monitoring is recommended, readings run for several months to show the movement has stopped.
Symptoms that point to subsidence repairs
- Fresh cracks showing on both the inside and outside of one wall

Rules for subsidence repairs in Northern Ireland
In Northern Ireland, the Building Regulations (Northern Ireland) 2012 apply and the council’s building control service approves structural work such as underpinning; minor like-for-like repairs usually need no approval. The Party Wall Act does not apply in Northern Ireland, so work to shared walls depends on deeds and agreement with neighbours.
Frequently asked questions
How much should I budget for subsidence repairs in Dungannon?
Guide prices for subsidence repairs in Dungannon start from about £2,200 per property, 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.
Can you survey a property in Dungannon?
Yes. We take enquiries from across Dungannon, including BT71, and from nearby places such as Cookstown and Armagh. Send photos for a free initial view and we will tell you what happens next.
Why do houses in County Tyrone crack?
Tyrone has glacial till over varied rock, with a small historic coalfield around Coalisland near Dungannon. Only an investigation can say why a particular building has moved.
Will past subsidence affect my home insurance?
It can, because insurers ask about previous subsidence at renewal or when you switch. Staying with the insurer who handled a claim is often simplest. Answer any new insurer’s questions honestly and keep the repair records, which show the problem was dealt with.
How do I know if cracks are subsidence?
Subsidence cracks are usually tapered, run diagonally from door and window corners, and show on both faces of the wall. Fine vertical cracks in new plaster are more often shrinkage. An engineer’s inspection, sometimes with monitoring, is the reliable way to tell.
