Premium Property survey including Drone and CWI inspection

Our complete damp and mould survey is a comprehensive, multi-disciplinary property inspection designed to identify all potential sources of moisture ingress and building-related defects. By combining internal assessment, cavity wall inspection, and advanced drone technology, we deliver a full diagnostic overview—not just symptoms, but the root causes.

This service is ideal for properties with persistent damp issues, complex defects, or where previous investigations have failed to provide clear answers.

Our Comprehensive Approach

We take a whole-property, evidence-led approach, ensuring no contributing factor is overlooked. The survey integrates three key inspection methods:

1. Internal Damp & Mould Assessment

• Full visual inspection of affected and surrounding areas

• Moisture readings with calibrated equipment

• Identification of condensation, penetrating damp, and rising damp

• Assessment of ventilation, insulation, and heating conditions

• Identification of mould growth patterns and contributing factors

2. Cavity Wall Inspection

• Assessment of cavity wall construction and condition

• Inspection for failed or inappropriate cavity wall insulation (CWI)

• Identification of bridging from debris or insulation defects

• Investigation of moisture tracking within the wall structure

• Use of borescope access (where required) to inspect cavity condition

• Evaluation of external wall defects and exposure risks

3. Roof & Gutter Drone Survey

• High-resolution aerial inspection of roof coverings and gutters

• Identification of slipped tiles, damaged slates, and defective flashing

• Detection of blocked or leaking gutters and downpipes

• Inspection of chimneys, valleys, and roof junctions

• Identification of defects contributing to water ingress into walls

Detailed Reporting

You will receive a fully integrated report that brings together findings from all inspection methods into one clear, professional document:

• Confirmed diagnosis of all damp-related issues

• Cross-referenced findings linking internal symptoms to external causes

• High-resolution photographs and drone imagery

• Cavity inspection images (where applicable)

• Identification of primary and secondary defect sources

• Prioritised remedial recommendations

• Clear distinction between:

  • Structural defects

  • Installation failures (e.g. insulation)

  • Environmental/lifestyle factors

• Guidance on long-term prevention and maintenance

Who This Service Is For

• Homeowners with ongoing or complex damp issues

• Landlords and property managers requiring detailed evidence

• Property buyers seeking a higher level of due diligence

• Owners of insulated cavity wall properties experiencing damp

• Anyone needing a comprehensive, single-survey solution

Key Benefits

• ✅ Full root-cause analysis (not just surface diagnosis)

• ✅ Combines internal, structural, and external inspection

• ✅ Eliminates the need for multiple separate surveys

• ✅ Independent, unbiased advice with no tied remedial work

• ✅ High-detail reporting suitable for disputes, insurance, or legal use

• ✅ Cost-effective compared to commissioning separate specialists

Typical Problems We Identify

• Persistent damp with multiple contributing causes

• Failed or saturated cavity wall insulation

• Roof defects causing hidden water ingress

• Blocked or defective guttering leading to penetrating damp

• Condensation linked to building design and ventilation

• Cold bridging within walls and structural elements
