Mould in Cyprus homes: how to remove it and stop it coming back

Why Cyprus homes get mould despite the sunshine

Mould grows where warm, moist indoor air meets a cold surface. Cyprus homes are built for hot summers, and insulating walls and roofs only became mandatory for new buildings with a 2007 ministerial order. Many older homes have none, so in winter their walls stay cold.

• Concrete thermal bridges: in a typical concrete-frame block, columns, beams and balcony slabs stay colder than the brick around them, which is why mould lines up along ceiling corners and beams.
• Single glazing: older aluminium sliding windows run with condensation on cold mornings.
• Sea air: homes on the coast in Limassol, Larnaca, Paphos, Ayia Napa and Protaras sit in damp air for much of the winter, especially at night.
• Gas and paraffin heaters: portable heaters release water vapour as they burn, and energy advisers warn they make indoor air very moist.
• Indoor laundry: a clothes horse in the bedroom on rainy days puts its water on the walls.
• Short bursts of heating: an hour of air conditioning warms the air, not the walls.
• Closed-up homes: holiday flats with shutters down and no airflow.
• Old stone village houses: they usually lack a modern damp-proof course, so ground moisture rises into the lower walls.

Condensation, leak or rising damp: how to tell

Find the water source before you clean. Condensation is the most common cause, and it looks different from water coming through the structure.

Is mould dangerous? Who is most at risk

Yes, mainly for your lungs. The World Health Organization's dampness and mould guidelines found that people in damp or mouldy buildings have up to a 75% greater risk of respiratory symptoms and asthma. UK health guidance also lists coughing, wheezing, airway infections, allergic rhinitis, eye irritation and eczema.

The people most at risk are those with asthma, allergies or lung disease, anyone with a weakened immune system (during chemotherapy, after a transplant or on immune-suppressing drugs), babies, children, older people and pregnant women.

When to clean it yourself and when to call a professional

The US Environmental Protection Agency says you can usually handle mould yourself if it covers less than about 10 square feet, roughly 1 square metre. UK guidance agrees that larger areas should be left to qualified professionals.

• Do it yourself: small patches on painted walls, tiles, grout and window frames, with no active leak.
• Book a cleaner: for a thorough deep clean of the room or home once the mould is treated, including curtains and wardrobes.
• Call a specialist: for mould over about 1 square metre, mould that returns within weeks, damp from a leak or the roof, rising damp, or a musty smell with no visible mould (it may be hidden inside walls).

A cleaner removes surface mould. A cleaner cannot fix a leaking roof or rising damp, so repair the cause first.

What products to use, and how to stay safe

Start with detergent and water. The US EPA recommends scrubbing mould off hard surfaces with detergent and water and drying them completely, and does not recommend bleach as a routine part of cleanup. Dead mould still has to be wiped away.

Wear long rubber gloves, an N95 or FFP2 mask (the European rating sold in Cyprus pharmacies) and goggles without vent holes. Open the windows, close the door to the rest of the home and keep children and pets out.

Bleach works best on hard, non-porous surfaces such as glazed tiles and glass, and less well on plaster, wood or fabric. If you use it, the CDC's limit is 1 cup of bleach per gallon of water, about 250 ml in 4 litres.

How to remove mould from painted walls and ceilings

1. 1

   Photograph it

   Take dated photos and lightly mark the edge of the patch, so you can see if it spreads. Useful evidence if you rent.

2. 2

   Prepare

   Move furniture away, cover the floor, open the window and put on gloves, mask and goggles.

3. 3

   Mist, do not dry-brush

   Spray the patch lightly with your cleaning solution first. Brushing dry mould throws spores into the air.

4. 4

   Wipe beyond the edges

   Wipe from the outside inwards, turning the cloth often. Spores can sit in the wall up to a metre around the visible patch, so treat an area about 1 m wider.

5. 5

   Rinse and dry

   Wipe with clean water, towel dry, then run a dehumidifier with the window shut until the wall is fully dry. Bag the cloths and wash your clothes.

6. 6

   Repaint only once dry

   Paint applied over mould is likely to peel. Once the wall is clean, dry and the cause is fixed, an anti-mould paint adds protection.

Bathroom silicone, grout and window frames

• Tiles: spray mould cleaner, leave it for the time on the label, scrub and rinse. Glazed tiles clean up well.
• Grout: scrub with a stiff brush and mould spray. Grout that stays black after a few treatments may need regrouting.
• Silicone: surface spots wipe off, but mould that has grown into the sealant will not. Cut the bead out, dry the joint and reseal with mould-resistant sanitary silicone.
• Aluminium frames: wipe condensation off every winter morning, and clear the sliding tracks and drainage slots so water can escape.

Limescale from hard Cyprus water roughens tiles and screens and helps grime cling; see limescale and hard water in Cyprus. Rinse well between a descaler and any bleach product.

Curtains, clothes, wardrobes and leather

• Curtains and clothes: brush off loose mould outdoors, air in the sun, then wash at the hottest temperature the label allows. Dry fully before storing.
• White cotton: US extension guidance suggests 2 tablespoons of chlorine bleach in about 1 litre of warm water for 5–15 minutes. Never bleach silk, wool or elastane.
• Sofas and mattresses: vacuum (empty it outside), dry in the sun, then sponge marks with equal parts rubbing alcohol and water after testing a hidden spot. Badly affected items may need replacing; see our carpet, sofa and mattress guide.
• Wardrobes on external walls: empty them, wash the inside with detergent, dry with the doors open, and stop packing clothes tightly. Mould-soaked chipboard backs may need replacing.
• Leather shoes and bags: brush outdoors, test a hidden spot, wipe with equal parts rubbing alcohol and water, and dry in moving air away from heat. Use saddle soap for stubborn marks, then condition.

How to stop mould coming back in a Cyprus winter

Control the moisture. The US EPA recommends keeping indoor relative humidity below 60%, ideally 30–50%. A cheap digital hygrometer shows where your home sits.

Keep the air conditioner clean too: see air conditioner cleaning in Cyprus.

Holiday homes and rentals closed for the winter

A Paphos flat or Protaras villa shut from November to April can grow mould on every soft surface. Before you lock up:

• Wash and fully dry all linen and store it in breathable bags, not sealed plastic.
• Leave wardrobes and internal doors open, and stand mattresses on their sides.
• Empty the fridge, switch it off and leave the door ajar.
• Leave moisture-absorbing tubs in wardrobes, and ask a neighbour or cleaner to air the place every few weeks.

On return, open up, check corners and behind furniture, wash the linen and clean the AC filters before switching on. For short-term lets, a pre-season holiday rental clean finds problems before guests do.

Renting? Report it in writing

Who pays depends on the cause and your tenancy agreement, and this is not legal advice. Good records help either way:

• Photograph the mould with dates, before and after cleaning.
• Report it to the landlord in writing (email or a messaging app keeps a timestamp), and mention any leak or window fault.
• Keep copies of replies. If you cannot agree, speak to a lawyer.

Landlords can book an end-of-tenancy clean between tenants, but fix the cause first or the patch will be back in January.

Finding a cleaner to help

Cyprus Cleaners is a directory: you contact independent cleaners and agree the work and price with them. In October 2026 about 35 cleaners are listed in Nicosia, 36 in Limassol, 10 in Larnaca and 13 in Paphos, typically at €9–€16 an hour, with one-off deep cleans from about €120.

Ask whether they clean small areas of mould, which products they use and who supplies masks and gloves. Browse cleaners in Limassol, or cleaning services in Nicosia, Larnaca and Paphos. For budgets, see what a cleaner costs in Cyprus.
