Where’s the job?

Scope of Works

• Inspect mechanical and passive ventilation components including extract fans, inline units, grilles and visible ductwork

• Measure airflow and fan rpm where accessible to confirm performance

• Clean accessible fan housings, grille covers and short duct runs; use PPE for dust and contamination

• Replace filters, seals and small components and fit new fan units where required

• Carry out simple fan replacement (wall/ceiling mounted units) and re-test for airflow and noise

• Provide a short written report with readings, photos and recommendations for further works

Typical Cost

Time on Site

Most routine inspections, cleaning and simple filter changes take 1–3 hours on site; a single fan replacement is typically 2–4 hours. Factors that extend time include restricted access, multiple rooms, required scaffolding or discovery of mould or electrical faults

Questions to Ask Your Tradie

• Are you experienced with the type of system I have (extract fans, inline, MVHR) and can you show previous work

• What testing will you do and will I receive before/after airflow figures or photos

• Do you carry public liability insurance and offer a parts/workmanship warranty

• Will you need hazard information (mould, asbestos risk) and how will you manage contamination

• Are access works (scaffold, cherry picker) charged separately and how are those costs estimated

• If you replace parts, what warranty do replacements carry and who supplies the parts

How to Avoid Surprises

• Ensure clear access to fans, grilles, loft hatches or cupboards before arrival

• Tell your tradie about any mould, damp or asbestos concerns in advance

• Arrange parking or a nearby drop‑off point for equipment to avoid delays

• Check building rules or warranties if you have communal MVHR or listed building constraints

• Have replacement filters or preferred parts available if you want immediate swap‑out

• Secure pets and notify of any alarm or building access procedures ahead of the visit
