Introduction

Property damage claims arise when buildings suffer physical damage that reduces their value, structural integrity or usability. Damage may result from subsidence, structural movement, construction works, water ingress, fire, impact damage or other external causes.

In many cases property owners, insurers and solicitors require independent professional evidence from Chartered Surveyors or RICS Registered Valuers to assess the nature of the damage, determine responsibility and quantify financial loss.

Expert witness surveyors frequently prepare reports relating to property damage claims to assist insurers, courts and legal professionals in resolving disputes.

Common Causes of Property Damage

Property damage may arise in a variety of circumstances including:

• Subsidence or ground movement
• Structural damage caused by neighbouring construction works
• Water ingress or flooding
• Fire damage
• Storm damage
• Vehicle impact damage
• Defective building works
• Tree root damage to foundations

Where disputes arise regarding the cause or extent of the damage,
expert surveyors may be instructed to investigate the issue.

The Role of the Expert Witness Surveyor

Expert witness surveyors provide independent professional opinion
regarding property damage and its financial implications.

Their responsibilities may include:

• Inspecting the damaged property
• Identifying the likely cause of damage
• Assessing structural defects
• Estimating the cost of remedial works
• Assessing diminution in property value
• Preparing formal expert reports for litigation or insurance claims

The expert’s duty is to provide impartial evidence supported by technical analysis.

Insurance Property Damage Claims

Insurance claims relating to property damage often require professional
assessment by Chartered Surveyors.

Expert surveyors may assist insurers and policyholders by:

• Assessing the cause of damage
• Determining whether damage falls within policy coverage
• Estimating the cost of repair works
• Assessing reinstatement cost

In disputed insurance claims, expert evidence may be required to determine
liability and the appropriate level of compensation.

Subsidence and Structural Movement

Subsidence is one of the most common causes of property damage claims.

Subsidence occurs when the ground beneath a building moves,
causing structural movement and cracking.

Expert surveyors investigating subsidence claims typically assess:

• Soil conditions
• Structural movement patterns
• Tree root influence
• Drainage defects
• Foundation design

These investigations help determine the cause of damage and appropriate
remedial works.

Assessing the Cost of Repairs

Expert surveyors often prepare schedules of remedial works
to estimate the cost of repairing damaged property.

These schedules may include:

• Description of repair works
• Estimated costs of remediation
• Recommendations for further investigation

Repair cost assessments often form part of insurance or litigation claims.

Diminution in Value

In some cases property damage may permanently reduce the market value
of a property even after repairs have been undertaken.

Expert witness surveyors may therefore assess the diminution in value
resulting from structural defects or stigma associated with previous damage.

Expert Reports for Legal Proceedings

Where property damage claims proceed to litigation,
expert surveyors may prepare formal reports for court proceedings.

These reports must comply with the Civil Procedure Rules,
particularly CPR Part 35 which governs expert evidence.

Expert reports normally include:

• Details of inspection
• Analysis of the damage
• Explanation of methodology
• Professional opinion regarding cause and financial impact
• Statement of truth confirming the expert’s duty to the court

Conclusion

Property damage claims can involve complex technical issues relating
to construction, structural behaviour and financial loss.

Expert witness surveyors play an important role in resolving these
disputes by providing independent professional evidence supported by
technical analysis and valuation methodology.
