Mould removal in Sydney homes
Bathroom ceilings, silicone, grout, wardrobes on external walls — mould shows up in the same places across Sydney apartments year after year. We treat the affected surfaces with professional anti-fungal products and tell you plainly what is causing it.
Why Sydney homes get mould
Poor bathroom ventilation
Most Sydney apartment bathrooms have no window and an exhaust fan vented into the ceiling cavity. Warm moist air condenses on the ceiling and silicone, which is exactly where black mould appears first.
Coastal humidity
Beachside suburbs like Bondi, Coogee and Maroubra sit at high humidity for months. Wardrobes on external walls and rooms that stay shut can develop surface mould without any leak.
Rising damp and leaks
Older terraces and ground-floor flats often have rising damp or a slow leak behind a wall. Surface treatment helps, but the moisture source has to be fixed or the mould returns.
Drying washing indoors
A single load dried inside releases litres of water into the air. In winter, in a closed apartment, that is enough to start mould on cold walls and ceilings.
How we treat it
- 1. Inspect the affected areas and identify the likely moisture source.
- 2. Contain the area and remove loose surface growth without spreading spores.
- 3. Apply anti-fungal treatment to tiles, grout, silicone, ceilings and painted walls.
- 4. Clean and dry the surfaces, then re-check silicone and seals.
- 5. Give you written advice on ventilation, extraction or repairs to stop it returning.
Where silicone is badly stained through, replacement is the honest fix — treatment alone will not restore it. We will tell you when that is the case rather than charging for a treatment that won't hold.
Mould and your final inspection
Bathroom mould is one of the most common reasons a vacate clean gets rejected in Sydney. If you are moving out, mould treatment pairs with our end of lease cleaning and, in the Eastern Suburbs, our local bond cleaning service.
Mould removal FAQs
Can mould be removed permanently?
Surface mould can be removed completely, but it returns if the moisture source stays. We treat the affected surfaces with anti-fungal products and then point out the ventilation or damp issue causing it so you or your landlord can fix it.
Is bleach enough for bathroom mould?
Bleach lightens mould on non-porous tiles but often leaves the growth in porous grout and silicone, so it darkens again within weeks. Professional anti-fungal treatment kills the growth rather than bleaching the colour out.
Who is responsible for mould in a rental — tenant or landlord?
In NSW, landlords must provide premises fit to live in, so mould caused by leaks, rising damp or inadequate ventilation is generally the landlord's responsibility. Mould caused by a tenant not ventilating can be the tenant's. Report it in writing early either way.
Do you treat mould as part of an end of lease clean?
Yes. Mould treatment is a common add-on to a bond clean, and it is usually the item agents flag in bathrooms at the final inspection.
