Building Pathology & Defect Analysis

Building pathology is the systematic investigation of building defects. When something goes wrong with a building — cracking, damp, water ingress, structural movement, material failure — we investigate to determine:

• What’s happening (the defect)
• Why it’s happening (the cause)
• What should be done about it (the remedy)

The word “pathology” comes from medicine, and the parallel is intentional. Just as a doctor diagnoses illness before prescribing treatment, we diagnose building problems before specifying repairs. Treating symptoms without understanding causes wastes money and leaves the underlying problem unresolved. If something’s gone wrong and the cause isn’t obvious, get it diagnosed properly before you spend on repairs.

We regularly see buildings where money has been spent on repairs that haven’t worked — because the diagnosis was wrong.

Damp treated with tanking when the cause was condensation. Cracking filled and decorated repeatedly without addressing the movement causing it. Roof repairs that fail because the underlying structure was the problem. Expensive interventions that miss the point entirely.

Correct diagnosis prevents this. It identifies what’s actually wrong, explains the mechanism of failure, and specifies repairs that address the root cause — not just the visible symptoms.

Cracking

Cracks appear for many reasons: structural movement, thermal expansion, moisture changes, foundation issues, defective materials, poor construction. Some are cosmetic; others indicate serious problems. We investigate to determine cause, assess significance, and recommend appropriate action.

Damp and water ingress

Dampness has multiple potential causes: rising damp, penetrating damp, condensation, leaking services, failed waterproofing. The correct remedy depends entirely on the cause. We diagnose the source and mechanism before specifying treatment.

Condensation and mould

Condensation problems involve complex interactions between heating, ventilation, insulation, and occupant behaviour. We analyse the conditions causing condensation and recommend practical solutions.

Roof defects

Leaking roofs, deteriorating coverings, failed flashings, ponding, structural issues — we investigate roof problems to identify what’s failing and why.

Structural concerns

When there are concerns about structural adequacy — excessive deflection, cracking patterns suggesting movement, deterioration of structural elements — we investigate and advise, bringing in structural engineers where appropriate.

Material failure

Spalling brickwork, concrete defects, corroding metals, deteriorating timber, failed sealants — materials fail for specific reasons. Understanding the failure mechanism informs appropriate repair.

Failed previous repairs

When previous repair attempts haven’t worked, we investigate why. Often the diagnosis was wrong; sometimes the repair was poorly executed. We establish what went wrong and what should be done instead.

You should commission a building pathology investigation if:

• You have visible defects you don’t understand
• Previous repairs haven’t solved the problem
• You’re concerned about structural adequacy
• You’re seeing water ingress or dampness
• You need evidence before pursuing others for defect costs
• You want to understand a problem before committing to expensive repairs
• You’ve acquired a building and discovered issues

Sometimes investigation reveals problems more serious than expected. A crack investigation might identify foundation movement requiring underpinning. Dampness investigation might uncover structural decay. Roof investigation might reveal that replacement is needed, not repair.

We tell you what we find. If the investigation reveals significant issues, you need to know — even if it’s not what you hoped to hear. Better to understand the full picture than to proceed with inadequate repairs.

If you’re pursuing others for defect costs — a builder, a previous owner, a third party whose actions caused damage — professional diagnosis provides the evidence you need. Our reports are prepared to stand up to scrutiny and can support claims or disputes.

To carry out repairs:

• Contract Administration — We can manage the remedial works, ensuring they’re carried out properly

If defects affect acquisition:

• Pre-Acquisition Surveys — If you’re buying and have discovered defects, we can investigate before you commit

For ongoing maintenance:

• Planned Maintenance Schedules — Once defects are addressed, plan systematic ongoing maintenance

If defects arise from neighbours’ work:

• Party Wall for Adjoining Owners — If damage was caused by neighbouring construction

If defects relate to dilapidations:

• Dilapidations for Landlords — Understanding defects when preparing or defending claims
• Dilapidations for Tenants — When defect causation is disputed in a dilapidations claim
