Kurnell Exhaust Fan Installation Services

Selecting the right exhaust fan depends on several factors including your bathroom size, ceiling height, moisture levels, and personal preferences. We assess your space to calculate the required airflow capacity measured in cubic metres per hour. Smaller bathrooms may need basic extraction fans, while larger ensuites might benefit from more powerful units or combination heat-light-fan models. If noise is a concern, we recommend quieter models with low sone ratings. For bathrooms without windows, more powerful extraction becomes essential. We guide you through the selection process, explaining the benefits of different models to help you make an informed decision.

Absolutely, we specialise in installing exhaust fans with proper external ducting to ensure moisture and odours are vented outside your home rather than into roof cavities. This involves running ducting from your ceiling-mounted fan through the roof space to an exterior vent, or installing wall-mounted units that vent directly through external walls. Proper external venting is crucial for preventing moisture buildup in roof cavities, which can lead to mould growth, timber rot, and insulation damage. We ensure all ducting is properly sealed, insulated where necessary, and fitted with weatherproof external vents to prevent water ingress and pest entry.

Installing a properly sized and positioned exhaust fan significantly reduces mould problems by removing moisture-laden air before condensation can settle on surfaces. When used correctly after showers and baths, exhaust fans extract humid air and replace it with drier air, lowering overall humidity levels. This prevents the damp conditions mould requires to grow on walls, ceilings, grout, and fixtures. For best results, we recommend running your exhaust fan during bathing and for at least twenty minutes afterwards. Installing timer switches or humidity sensors can automate this process. While exhaust fans are highly effective for mould prevention, existing mould should be properly cleaned before installation for optimal results.

Exhaust fans benefit from regular basic maintenance to maintain optimal performance and extend their lifespan. The most important task is cleaning the cover grille and internal fan blades to remove dust, lint, and debris that can restrict airflow and cause noise. This should be done every few months depending on usage. External vents should also be checked periodically to ensure they're not blocked by leaves, spider webs, or other obstructions. The motor and electrical components typically require little maintenance but should be inspected if you notice reduced airflow, unusual noises, or intermittent operation. We can perform professional maintenance checks and cleaning if you prefer not to do it yourself.
