Cracks in walls, ceilings, and structural elements can be worrying, particularly when they appear to be getting worse or are accompanied by signs of movement. A structural crack investigation helps determine whether cracking is cosmetic, movement-related, or linked to a more serious structural issue.
Our structural engineers investigate cracking within buildings, assess the likely cause, and provide clear professional advice on the most appropriate next steps. Whether you are a homeowner, property buyer, landlord, developer, architect, or commercial property owner, our team can provide the structural crack investigation and reporting required.
We understand that visible cracking can be unsettling. Our role is to provide a measured professional assessment and explain the issue clearly, supported by the Wilson True Standard of professionalism, integrity, and attention to detail.
What Is a Structural Crack Investigation?
A structural crack investigation is a professional assessment carried out by a structural engineer to determine the cause, significance, and potential implications of cracks within a building.
The investigation establishes:
- Whether the cracks are structural in nature
- Whether the building appears to be moving
- Whether the cracking is progressive or historic
- Whether further monitoring or intrusive investigation may be required
- Whether remedial works are likely to be necessary
Common reasons for an investigation:
- Cracks appearing in internal or external walls
- Cracks above doors or windows
- Step cracking in brickwork
- Diagonal cracking near openings
- Cracks that appear to be widening
- Cracks accompanied by sticking doors or windows
- Cracks identified during a house purchase survey
- Concerns about possible subsidence or structural movement
A structural crack investigation provides clarity and allows informed decisions to be made about repairs, further investigation, or monitoring.
What Causes Cracks in Buildings?
Cracks can occur for many reasons, and not all cracking indicates a serious structural problem.
Common causes of cracking include:
- Normal shrinkage and settlement
- Thermal movement
- Minor building movement over time
- Differential settlement
- Subsidence
- Tree-related movement in shrinkable soils
- Roof spread
- Inadequate structural support
- Poor previous building alterations
- Water ingress affecting structural elements
A structural crack investigation allows an engineer to assess the cracking pattern and surrounding structure to determine the likely cause.
Crack Investigations for Houses, Purchases and Commercial Property
Homeowners request a structural crack investigation when cracks begin to appear or when they are concerned that movement may be affecting their home. We regularly investigate cracking in period properties, Victorian and Edwardian homes, modern houses and extensions, flats and maisonettes, and homes altered by previous structural work.
During a property purchase, a crack investigation helps buyers understand whether cracking is likely to be structural, whether movement appears historic or ongoing, and whether the issue may affect the purchase decision. We also provide structural crack investigation for commercial properties including offices, industrial units, retail premises, apartment blocks, and mixed-use buildings for due diligence, asset management, refurbishment planning, or insurance purposes.
