Structural surveys and crack monitoring in County Tyrone
Structural surveys and crack monitoring in County Tyrone starts with the ground. Clay shrinkage is less of a concern in County Tyrone, so other causes such as drains, poor footings or older walls are checked first, and the buildings here are mostly market-town terraces, so the repair has to suit both.

Is County Tyrone prone to ground movement?
Tyrone has glacial till over varied rock, with a small historic coalfield around Coalisland near Dungannon.
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.

Which repair method suits a home in County Tyrone?
Tell-tales and crack-width monitoring
Gauges are fixed across key cracks and read at set intervals, or reference studs are measured with callipers to a fraction of a millimetre. The readings show whether each crack is widening, closing or stable, and whether any change follows the seasons.
Best for: Tracking individual cracks over the seasons
Engineer’s structural inspection and report
A chartered structural engineer visits, records the cracks, checks the walls, floors, drains and nearby trees, and writes a report on the likely cause and next steps. It may recommend monitoring, investigations such as trial pits, or a repair specification.
Best for: A first expert opinion on any significant cracking
Level monitoring
Survey points are fixed around the building and their heights measured against a stable datum on each visit. This shows whether one part of the house is dropping or rising compared with the rest, which crack widths alone cannot reveal.
Best for: Suspected subsidence or heave across a whole house
What happens when we carry out structural surveys and crack monitoring in County Tyrone?
Engineer’s inspection
We can arrange an independent chartered structural engineer to inspect. They record the damage, assess likely causes and recommend whether monitoring, drain surveys or trial pits are needed before any repair decision.
Seasonal readings
Readings are taken at intervals across the seasons, typically including late summer when clay is driest and late winter when it is wettest. The engineer checks each set against the base reading and decides whether more visits are needed.
Repair or close
If the readings show the house is stable, the engineer specifies the repair and we confirm a fixed price in writing. If movement continues, the cause is investigated further before a foundation repair is designed.
Signs you may need structural surveys and crack monitoring
- Cracks reopening after being filled and decorated
- Cracks that seem wider after a hot, dry summer
- Doors and windows sticking at some times of year only
- A crack you are unsure is old or new
Do you need approval for structural surveys and crack monitoring in Northern Ireland?

Structural surveys and crack monitoring in County Tyrone: questions and answers
Why do houses in County Tyrone crack?
Tyrone has glacial till over varied rock, with a small historic coalfield around Coalisland near Dungannon. Parts of County Tyrone lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.
How much will structural surveys and crack monitoring cost in County Tyrone?
On Northern Ireland rates, structural surveys and crack monitoring starts from about £440 per property, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
Who carries out the crack monitoring?
An independent chartered structural engineer designs the monitoring and interprets the readings. We can arrange the engineer for you. We are the repair contractor, so we carry out the repair the engineer specifies once the monitoring has shown what is needed.
How long does crack monitoring take?
Monitoring normally runs for 6 to 12 months, because readings need to cover both the dry and wet seasons on clay soils. Shorter periods can be enough where the cause is clearly non-seasonal, such as a drain leak that has been repaired. The engineer decides when there is enough evidence.
What do BRE crack categories mean?
BRE Digest 251 groups damage by typical crack width. Category 0 is under 0.1 mm, 1 up to 1 mm, 2 up to 5 mm, 3 from 5 to 15 mm or several of about 3 mm, 4 from 15 to 25 mm, and 5 usually over 25 mm. It is a guide to severity, not a diagnosis of cause.
