Downloads: 0

This professional Chartered Surveyor report template supports cavity wall insulation (CWI) extraction assessments and recommendations. Document premises details, customer information, surveyor credentials, and on-site inspection results. Record existing CWI materials and condition, add borescope evidence, and evaluate wall ties, damp proof course, and external wall integrity. Recommend ventilation upgrades such as a whole-house PIV unit and trickle vents, and specify re-insulation using bonded carbon bead where suitable. Use this template to improve internal comfort, reduce condensation and mould risk, and lower energy costs while maintaining a clear audit trail with photos and declarations.
