Mould is the single most common cleaning problem we see in Sunshine Coast homes. Our climate is what it is — warm, humid, and especially through the wet season, very generous with the conditions mould loves. The good news is that prevention is mostly habits, not products.

The places mould always starts

In every Sunshine Coast home we clean regularly, mould first shows up in the same places. The shower silicone. The grout around the bathroom basin. The corners of bedrooms with poor ventilation. The cool side of an air conditioner unit. The back of furniture that sits against an external wall. The window tracks. Behind the washing machine.

If those areas are clean and dry every week, mould struggles to get a foothold. If they are damp and ignored, mould wins.

The habits that actually work

Open the windows. The single most effective thing a Sunshine Coast homeowner can do is move air through the house. Even in the wet season, ten minutes of cross-ventilation in the morning resets the indoor humidity. Air conditioning helps but it is not a substitute for fresh air.

Run the bathroom exhaust fan for fifteen minutes after every shower. Not while you are showering — after. The hot steam needs to clear out, and that takes longer than the shower itself.

Wipe down the shower screen and the wet surfaces of the bathroom after each use. A microfibre cloth and twenty seconds. This single habit is the difference between a bathroom that needs a mould clean every six weeks and one that does not.

Dry damp towels properly. A towel left bunched on a hook in a humid bathroom is a mould factory. Either hang flat or run the towel through the dryer briefly.

The cleaning products that work

Mould-killing products do not need to be aggressive chemicals. Diluted white vinegar handles most surface mould on tile and grout. Sodium percarbonate (oxygen bleach) works on fabric and porous surfaces without the smell or the toxicity of chlorine bleach. For silicone that has gone black, the only real fix is removing and replacing the silicone — products that promise to bring black silicone back to white rarely work.

We use eco-friendly mould products in our cleans because the alternative is leaving a strong chemical residue in a closed coastal home. If you do use chlorine bleach, ventilate aggressively.

The harder mould problems

Mould inside cavity walls, mould in the ceiling, mould that smells but you cannot see — these are not surface cleaning problems. They are moisture ingress problems. A coastal home with persistent unexplained mould usually has a roof leak, a flashing problem, or a poor drainage situation that needs a tradie, not a cleaner.

If a Sunshine Coast home has had unexplained mould for more than a few months, get a builder or a building inspector to look at the moisture sources. Cleaning the visible mould without addressing the source is a losing game.

The seasonal calendar

A practical mould prevention calendar for a Sunshine Coast home looks something like this. Spring — clean the gutters, check the roof, service the air conditioner. Summer — keep the windows open when possible, run the AC at a moderate temperature rather than freezing-cold cycles. Autumn — deep clean the bathrooms, replace silicone if it has gone black, check the laundry. Winter — let some sun into the rooms that get less of it.

It is not glamorous. But the homes that follow this kind of pattern stay clean and the homes that do not require more expensive intervention every year.

We clean Sunshine Coast homes from Caloundra to Noosa. Mould management is part of what we do on regular maintenance cleans. If you have a mould issue that has crept up, give us a call.
