External Defects & Drainage Investigations
Targeted investigation of external building defects, drainage issues and weathering pathways that may be driving internal damp symptoms.
External Defects & Drainage Investigations with clearer reasoning
Many internal damp symptoms are driven by something outside the room where the damage is appearing. This service focuses on the external envelope, defect pathways and drainage-related causes that may be feeding moisture into the building.
That can include roofing details, flashing, rainwater goods, pointing, masonry condition, junctions, render, ground levels and drainage issues where surface symptoms alone are not enough to explain the problem.
It is especially useful where the moisture pattern suggests ingress from outside, or where a client needs a clearer picture before commissioning repairs.
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.

Clarity First
External Defects & Drainage Investigations scope and pricing context
This site should talk about pricing carefully: enough to set expectations, without pretending every case fits a flat template. Complexity, property type and reporting depth matter.
External defect investigation
Scope depends on property size, access and the defects involved
Drainage or ingress-led review
May sit alongside a wider damp or pathology 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.
