Prevent bathroom mould and moisture damage with a properly ducted exhaust fan. We install and replace exhaust fans across the Mornington Peninsula — all to BCA code.
📞 0418 383 232Bathroom and kitchen moisture is a serious problem on the Mornington Peninsula — the coastal climate means humidity levels are already elevated, and without adequate ventilation, mould takes hold quickly. Victorian building regulations require exhaust fans in all wet areas of new homes, and many older Peninsula properties are well overdue for an upgrade from an underpowered or incorrectly installed unit. Impulse Electrical installs exhaust fans that actually do the job — properly ducted, correctly sized, and code-compliant.
⚠ Victorian Building Code requirements for exhaust fans:
• All habitable wet areas (bathrooms, ensuites) must have mechanical ventilation
• Exhaust must discharge to outside air — not into roof cavities or wall spaces
• Minimum airflow rates apply based on room volume (typically 25L/s)
• Ducting must use rigid or semi-rigid duct — flexible duct is not compliant for long runs
A standard bathroom exhaust fan installation (replacing an existing fan) costs $120–$220. A new installation with ceiling penetration and external duct run is $250–$450. Combined light/heat/exhaust units cost $350–$600 installed. Prices vary depending on ceiling height, roof space access, and duct run length.
Yes — under Australian Building Code (BCA) requirements, exhaust fans must expel moisture to outside the building, not into the roof space. Venting into the ceiling cavity causes mould, timber rot, and structural damage. Many older Peninsula homes have fans incorrectly vented into the roof — we can correct this and bring your installation up to code.
Absolutely. 3-in-1 units (exhaust + light + heat lamp) are very popular in Peninsula bathrooms — especially useful in winter. 4-in-1 units add a second heat lamp for faster warmth. These require a dedicated circuit with a multi-gang switch. We install these regularly and can advise on the best unit for your bathroom size.
