14 Frequently Asked Questions
01 Quick Answer
Professional CCTV Camera Condition Inspections provide independent evidence that can support insurance investigations and claims.
Our reports help identify drainage defects, assess their condition and provide the documentation insurers, loss adjusters and property professionals may require when investigating drainage-related damage.
02 When Insurance May Be Involved
Drainage investigations are commonly requested following:
-
Escape of water incidents
-
Flooding
-
Subsidence investigations
-
Structural movement
-
Drain collapses
-
Damage to buildings or contents
-
Property purchase disputes
-
Liability investigations
Early investigation can help establish the cause before further deterioration occurs.
03 Escape of Water Claims
Leaking underground drains can sometimes contribute to water escaping into surrounding ground or nearby structures.
A CCTV Camera Condition Inspection can help identify:
-
Cracked or fractured pipes
-
Defective joints
-
Pipe collapses
-
Blocked drains causing backing up
-
Areas where further investigation may be required
Providing accurate evidence early often helps prevent unnecessary delays.
04 Subsidence & Structural Damage
Leaking drains are one of several factors that may contribute to ground movement.
Where drainage is suspected, our inspections help identify:
Defective underground drainage
Leaking pipe joints
Washout of surrounding soil
Root penetration
Structural defects within the drainage system
Our reports provide factual observations to assist insurers and structural professionals with their investigations.
05 Long-Standing vs Sudden Damage
Insurance policies often distinguish between:
Sudden Damage
Unexpected events such as a collapsed drain or sudden pipe failure.
Long-Standing Deterioration
Gradual deterioration caused by ageing, wear, corrosion or lack of maintenance.
Our CCTV reports document the visible condition of the drainage system and, where possible, indicate whether defects appear consistent with recent failure or long-term deterioration.
Please note that insurance cover and liability decisions remain the responsibility of your insurer.
06 Evidence Insurers May Require
Depending on the claim, insurers may request:
-
Professional CCTV inspection report
