Mould in the kitchen: the hidden hotspots to check

Updated · 3 min read

Short answer: Kitchen mould thrives on humidity from cooking and washing up, and hides under the sink, behind appliances, in cupboards and around windows. Ventilate while cooking, fix any leaks, keep surfaces dry, and treat affected areas to stop it spreading.

Why kitchens get mould

Cooking, boiling the kettle, washing up and running the dishwasher all put water into the air. A kitchen is warm, so that air carries the moisture until it reaches something cold, and much of what happens next is out of sight: inside cupboards, behind appliances and under the sink, where the air barely moves.

The second source is plumbing. Apart from the bathroom, no room has more water connections, and most of them sit behind cupboard doors and kickboards. A slow drip can soak a cabinet base for months before anyone notices.

The hidden hotspots

  • Under the sink. The most common spot. Waste traps, tap connectors and the dishwasher and washing-machine hoses can all weep. A swollen or stained cupboard base usually means a slow leak.
  • Cupboards on outside walls. The back panels stay cold, condensation forms behind tins and packets, and green mould turns up on shelves and cabinet backs.
  • Behind and under the fridge and dishwasher. Many fridges have a drip tray that collects defrost water, and the hoses behind a dishwasher can work loose.
  • Around the window and along the worktop sealant. Steam condenses on the glass and runs down; tired silicone behind the sink lets water into the wall.
  • Rubber seals on the fridge door, and on the washing machine if it lives in the kitchen.

What makes it worse in Cyprus kitchens

Plenty of apartment kitchens are small, closed rooms, and some have no window at all, so everything depends on the cooker hood. Many hoods recirculate air through a filter instead of venting it outside: they catch grease, but the steam stays in the room. In winter the windows stay shut and the outside walls turn cold, so condensation that would dry off in summer lingers. Seafront flats add humid coastal air on top.

How to tackle it yourself

Switch the hood on before you start cooking and leave it running for a while afterwards; if it recirculates, open a window as well. Put lids on pans, and let the dishwasher cool before you open it so the steam doesn't pour into the room. Wipe the window and sill in the morning while they're wet. Leave a gap behind the fridge, keep cupboards on outside walls less crammed, and check under the sink with a torch every few weeks.

Small spots of surface mould on a hard surface can be wiped off with a damp cloth and a mould cleaner, then dried. Keep cleaning products away from open food, and throw away any food with mould on it. Painting over a mouldy patch won't hold: mould grows back through fresh paint.

When to get help

If a cupboard keeps going mouldy, the base is water-stained or swollen, or there's a musty smell you can't trace, there's a moisture source behind the units. We find the cause before we touch the mould, so the fix lasts. A mould and damp inspection gives you moisture readings in every affected room and a written report with the quote; typical fixes include upgrading the extractor or insulating the cold spot. Mould treatment then clears the growth.

Common questions

Where does mould hide in a kitchen?
Under the sink, inside cupboards on external walls, behind the fridge and dishwasher, around windows, in worktop sealant, and in the fridge door seal.
Why is there mould under my kitchen sink?
Almost always a slow plumbing leak or condensation keeping the cupboard base damp. Check pipes and the floor of the unit for water staining.
Is kitchen mould a health risk near food?
It's a hygiene concern, especially near food and packaging. Discard mouldy packaging, clean and treat surfaces, and fix the moisture source.
How do I stop kitchen mould?
Ventilate while cooking, fix leaks, keep surfaces and cupboards dry, don't store damp items, and treat any growth early.
Does a cooker hood stop kitchen mould?
Only if it takes the steam outside. A hood that vents through a duct removes moisture while you cook. One that recirculates through a filter catches grease and smells but puts the damp air back into the room, so open a window as well. Either way, switch it on before you start cooking.
Should I throw away food from a mouldy cupboard?
Throw away any food with visible mould on it, and anything in open or cardboard packaging that has been touching the mould. Sealed tins and jars can be wiped clean and kept. Then clean and dry the cupboard fully before you put food back, and find out why it got damp.
