Dyson Cavity Wall Extraction Report

by Lauren Rimmer, from the Community

Use this Dyson Cavity Wall Extraction Report to capture post-work details after cavity wall insulation extraction. Record client information, property type, construction and year built, fuel type, and cavity width. Verify full removal of material and debris, installation of cavity brushes, removal and sleeving of ventilators, and any additional vents fitted. Confirm combustion vent suitability and cleanliness before handover, and assess readiness for re-injection. Include comments for each step and collect auditor and customer signatures.

Post Extraction and Cavity Wall Survey
This template supports post extraction and cavity wall surveys for residential and commercial properties. Inspect structural and external conditions, finishes, guttering, and access. Capture heating type, flue and chimney details, and verify safety monitors. Conduct boroscope checks, assess wall ties, confirm insulation removal, fit cavity brushes, and make good extraction holes. Check and document vents, trickle vents, and ventilation requirements per PAS 2035. Perform internal inspections for damp, condensation, and loft ingress, with photos and measurements of cavity depths across elevations. Includes dynamic risk assessment and installation checks to ensure suitability for reinstallation and occupant safety.

Cavity Wall Pre-extraction and Cleaning Survey
This pre-extraction and cavity cleaning survey template supports inspections of failed cavity wall insulation prior to removal. It captures client and property details, construction age and type, heating and secondary heat sources, external finishes and condition, and any remedial works required. Inspectors can document internal issues such as damp or mould, ventilation and mechanical fans, air vents needing sleeving, adjoining insulation, omitted areas, and average cavity depths. The form covers materials to be extracted (fibre, foam, rockwool, polystyrene bead, debris), elevation photos and boroscope checks, and summary findings with reasons for extraction. It also includes a dynamic risk assessment and client declaration to support safe, compliant operations.

Post Extraction and Cavity Wall Survey PAS 2035
Use this checklist to survey cavity walls after insulation extraction and assess suitability for reinstallation in line with PAS 2035. Capture site and property details, tenure and construction, external finishes and structural condition. Record heating appliances, flue and chimney locations, and verify alarms. Document access and equipment needs. Perform post extraction inspections with borescope images, check wall ties, cavity cleanliness, vents, and finish repairs. Include internal checks for damp and condensation, ventilation requirements, and loft inspection. Measure cavity depths by elevation and log photos. Complete a dynamic risk assessment and client declaration. Finalize with installation checks and signatures.

Post Extraction and Cavity Wall Survey Checklist
This template supports post extraction audits and cavity wall survey work for residential and commercial buildings. It captures address and tenure details, property type, age, and floor construction, then assesses exterior finishes and structural condition. It verifies heating appliances, flues, chimneys, ventilation, and safety monitors, and records internal inspections for damp, mould, and condensation. For cavity wall insulation, it documents scheme type, materials, vents, adjoining properties, and requirements under PAS 2035. It includes elevation photos, DPC measurements, cavity depth checks, borescope evidence, dynamic risk assessment, and installation checks to confirm readiness for reinstallation and compliance.
