Mould removal in Sydney
Mould treatment for bathrooms, ceilings, silicone and grout across Sydney. We remove the visible growth, treat the surface and tell you what is causing it so it does not come back in the same spot. Established in 2009, Angelic Cleaning NSW has treated mould in Sydney homes for over 17 years.
Where mould shows up most
Bathroom silicone and grout
Mould roots itself into silicone and porous grout. Wiping the surface only hides it for a few weeks. We strip affected silicone, treat the substrate and reseal where needed.
Ceiling spots and water damage
Ceiling mould usually signals a leak, poor ventilation or condensation. We clean and treat the visible mould and tell you if a plumber or roofer needs to fix the source first.
Window frames and tracks
Condensation on aluminium and timber frames is common in Sydney apartments. We clean tracks, frames and glass, then treat with a low-toxicity solution that slows regrowth.
Wardrobes and behind furniture
Poor airflow creates black spots on walls and clothes. We treat the surface and advise on spacing and ventilation so the problem does not return the next season.
Why mould keeps coming back
Mould needs moisture, organic material and still air. Wiping it with bleach kills the colour but often leaves the roots in grout and silicone. The only lasting fix is to remove the growth properly, fix ventilation or leaks, and keep surfaces dry. In rental properties, mould is one of the most common reasons a bond clean gets rejected — which is why we bundle it with end of lease cleaning in Sydney when needed.

Mould removal FAQs
How much does mould removal cost in Sydney?
Small bathroom treatments start around $120 to $180. A full bathroom with ceiling, shower and window work is usually $250 to $450. Severe cases requiring silicone replacement and multiple rooms are quoted on inspection.
Can mould be removed permanently?
If the moisture source is fixed, yes. We remove the visible mould and treat the surface, but if the room stays damp it will regrow. We identify the likely cause and tell you what to fix.
Is your mould treatment safe for kids and pets?
We use low-toxicity, non-bleach solutions and ventilate thoroughly. Occupants should stay out of treated rooms for the recommended drying time, which we explain before we leave.
Do you guarantee the mould will not come back?
We guarantee our workmanship on the areas treated. We cannot guarantee against regrowth if the underlying moisture issue is not resolved, which is why we report the cause to you.
Will my agent accept your mould invoice at final inspection?
Yes. We itemise the treated rooms and include before-and-after notes where appropriate. Mould treatment is commonly required as part of a bond clean and can be booked together.
