Leak, Drainage & External Defect Investigation
Where surface readings aren't enough, we perform selective exposure and CCTV drainage surveys to confirm hidden water ingress and structural defects. Findings are documented with photography and video evidence.
Leak, Drainage & External Defect Investigation with clearer reasoning
Some moisture problems cannot be resolved from observation alone. This service adds selective invasive investigation and CCTV drainage inspection to confirm what is happening inside concealed construction or below ground.
It is used where surface readings are ambiguous, where ingress is suspected from drainage or buried elements, or where structural defects need to be ruled in or out.
Findings are documented with photography and video so clients and contractors share a clear view of the evidence.
What clients need from this service
The value is not simply receiving a report. It is getting a clearer explanation, a more defensible diagnosis and a practical route forward.

Leak, Drainage & External Defect Investigation scope and pricing context

Invasive or CCTV-led investigation
Access, reinstatement and drainage length affect cost
Combined survey plus invasive follow-on
Often staged after initial assessment
* Exact pricing depends on the property, complexity and reporting requirements.
How this service is delivered
The process should move from context and evidence gathering through to analysis and a usable recommendation.
Understand the case
We establish the symptoms, the property context, any previous advice, and what decision the client needs to make.
Inspect and analyse
We gather the right evidence, assess likely causes, and test the issue against the building context rather than jumping to treatment.
Report and recommend
You receive clearer findings, practical next steps, and where needed a more structured remedial direction.
