Cavity Wall Inspection Survey
Our cavity wall inspection survey provides a detailed assessment of your property’s cavity walls to identify defects, insulation issues, and potential causes of damp penetration. This service is designed to diagnose problems that are often hidden within the wall structure, ensuring accurate recommendations and preventing unnecessary remedial work.
Our Approach
We undertake a systematic inspection using specialist tools and techniques to assess both the condition and performance of cavity walls. The survey is tailored to the construction type, age, and exposure of the property.
The inspection typically includes:
Visual assessment of internal and external wall conditions
Inspection for signs of damp ingress, cold spots, and mould growth
Assessment of cavity wall insulation (CWI) condition and suitability
Identification of bridging issues caused by debris, poor installation, or insulation failure
Examination of wall ties, weep holes, and ventilation points (where accessible)
Review of external defects, including:
Cracked brickwork or render
Defective pointing
Faulty seals around openings (windows/doors)
Investigation into contributing factors such as exposure to weather and building orientation
Where necessary, minimally invasive inspection methods (e.g. borescope surveys) may be used to view inside the cavity. This will involve drilling the wall circa 30mm then inserting a camera. Holes will be filled on completion but we are unable to match colour.
Detailed Reporting
You will receive a comprehensive report outlining the findings in a clear and professional format, including:
Condition of the cavity wall and insulation (if present)
Identification of defects, blockages, or moisture pathways
Photographic evidence and, where applicable, internal cavity images
Explanation of how identified issues are affecting the property
Targeted recommendations for remedial action or further investigation
Guidance on whether insulation removal, repair, or replacement is required
Who This Service Is For
Homeowners experiencing unexplained damp or cold areas
Landlords and property managers addressing tenant complaints
Property buyers carrying out due diligence before purchase
Owners of properties with existing cavity wall insulation concerned about performance or failure
Key Benefits
✅ Identifies hidden defects within cavity walls
✅ Prevents misdiagnosis of damp problems
✅ Supports informed decisions on insulation and repairs
✅ Independent, unbiased advice (no tied installation services)
✅ Helps avoid costly and unnecessary remedial works
Common Issues We Identify
Saturated or failed cavity wall insulation
Bridging caused by debris or poor installation
Water penetration through external masonry
Cold bridging leading to condensation and mould
Inadequate detailing around openings and junctions
