Pre-Inspection Checklist
Before scheduling duct maintenance, confirm the work scope and safety requirements. Start by assessing the ventilation system layout, noting kitchen hoods, supply and return ducts, extract fans, and any access panels. Inspect visible components for grease buildup, dust accumulation, unusual odors, or signs of moisture. Ask for a site walk-through that includes considerations, and request Duct cleaning documentation of the cleaning approach, tools, and protective measures. Ensure the plan addresses hygiene-sensitive areas, with clear procedures for isolating work zones, managing debris, and protecting surrounding surfaces. Finally, verify that the contractor can tailor the method to your ventilation type, including duct material and any fire safety constraints.
Cleaning Plan and Method Check
A thorough service follows a structured method rather than a surface wipe. Confirm that the contractor uses source-to-exhaust strategies to dislodge and remove contaminants, not just redistribute them. Ensure they plan for controlled access points, including appropriate containment and filtration to prevent debris spread. Look for evidence of mechanical agitation combined with vacuum extraction, with attention to fan housings and duct Kitchen extract cleaning runs where airflow turbulence traps residue. For kitchen systems, request confirmation that grease, fumes, and particulate matter are treated as separate challenges with suitable handling. The checklist should also include filter handling guidance, inspection points during the process, and a clear explanation of what will and won’t be cleaned during the visit.
Verification, Hygiene Controls, and Aftercare
After the cleaning phase, insist on verification steps that confirm removal and system readiness. Request an end-of-job inspection that compares pre-clean findings with post-clean condition, including airflow-relevant areas and accessible duct segments. Ensure the contractor confirms waste disposal practices and that all access panels are reinstalled securely. Ask how they prevent recontamination during and after service, including whether surfaces are wiped down to remove residual dust and grease. For kitchens and other high-contamination zones, request guidance on operating practices that support cleanliness, such as hood usage habits and filter maintenance routines. Include a maintenance schedule recommendation aligned to your facility type so ducts remain efficient and hygienic.
