Background
A prospective purchaser requested a structural inspection after observing cracks around several windows and doors.
There were concerns that the property could be affected by subsidence.
Structural inspection
A crack survey and structural assessment were undertaken to determine the likely cause of the observed defects.
Both internal and external areas were inspected.
Findings
The cracking pattern was consistent with historic settlement commonly found in older residential properties.
No evidence of significant ongoing subsidence was identified.
The property appeared to be performing as expected for its age and construction type.
Recommendations
Minor repairs to the affected masonry and finishes were recommended.
No major foundation works were considered necessary.
Outcome
The inspection provided reassurance to the purchaser and helped support an informed property purchase decision.
Outcome: Historic settlement confirmed — not active subsidence. Purchaser proceeded with confidence.
Frequently Asked Questions
How do I know if my house has subsidence?
Signs of subsidence include diagonal cracking stepping through mortar joints around windows and doors, sticking doors or windows that have recently become worse, and visible gaps between walls and floors or ceilings. However, most cracking in houses is not subsidence — it is historic settlement, thermal movement or shrinkage. A structural engineer can identify the cause from the crack pattern, property age and construction.
What is a subsidence survey?
A subsidence investigation involves a Structural Engineer assessing the cracking pattern, the construction of the property and the visible ground conditions to consider whether the evidence indicates active or historic movement. The inspection and technical work are undertaken by a Structural Engineer with 5+ years' experience. The written report is prepared for sharing with mortgage lenders, insurers and solicitors where relevant.
Do I need a structural engineer for suspected subsidence?
If a surveyor has flagged potential subsidence, or if your insurer requires a structural engineer's opinion, a Specific Structural Inspection (SSI, £480) provides the assessment and written report needed. Many suspected subsidence cases turn out to be benign historic settlement — a structural inspection establishes this without the cost of intrusive investigation.
