Structural surveys and crack monitoring in Belfast
A structural survey in Belfast starts with an independent chartered structural engineer inspecting the cracks, the walls, the drains and any trees nearby. We can arrange that inspection, and the report sets out whether monitoring or a repair comes next.

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. If you are just outside Belfast, we also cover Newtownabbey (4 miles), Lisburn (7 miles) and Carrickfergus (10 miles).
Clay shrinkage is less of a concern in County Antrim, so other causes such as drains, poor footings or older walls are checked first. 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.
Which repair method suits a home in Belfast?
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 Belfast?
Install monitoring points
Tell-tales, measuring studs or level points are fixed at the locations the engineer chooses. A base reading is taken on the first visit, so every later reading can be compared against it.
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.

Structural surveys and crack monitoring in Belfast: questions and answers
How much will structural surveys and crack monitoring cost in Belfast?
Guide prices for structural surveys and crack monitoring in Belfast start from about £440 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.
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.
What happens after the monitoring ends?
If the readings show the building is stable, the engineer specifies a repair, usually crack stitching and making good. If movement continues, further investigation and a foundation repair design follow. Either way, we confirm a fixed price in writing once the repair is specified.
When should I get a structural engineer’s report?
It is worth getting one when cracks are wider than a few millimetres, tapered, getting worse, or accompanied by sticking doors and sloping floors. A mortgage valuer or insurer asking for one is another clear trigger. Fine, stable hairline cracks often do not need one.
