HDB Mould Removal Singapore

Mould is one of the most common problems in Singapore HDB flats. Our climate keeps indoor humidity high all year, and even well-ventilated flats trap moisture in bedrooms, bathrooms, the household shelter and the service yard. Four Solutions removes HDB mould at the source and protects the surface so it does not keep coming back.

Why HDB flats get mould

Air-conditioning condensation. Cold air against warm ceilings and walls creates moisture, so mould often appears near aircon units and ledges.
Poor ventilation. Closed bedrooms, wardrobes against external walls and the household shelter get little airflow.
Bathroom and service yard damp. Constant moisture with limited exhaust lets mould grow on ceilings, grout and walls.
Leaks and seepage. Hidden pipe leaks or ceiling seepage from the unit above keep a surface permanently wet.

How we remove mould in HDB flats

We inspect the affected areas with moisture meters to find the cause, remove the mould with professional biocide instead of painting over it, then apply anti-mould protection where suitable. If the cause is a leak or seepage, we flag it so the water source can be fixed, because treatment alone will not hold while moisture remains.

Frequently asked questions

Can you remove mould in an HDB household shelter?

Yes. Household shelters have no ventilation and often store damp items, so they are a common mould spot. We treat the surfaces and advise on keeping the shelter dry.

Will the mould come back after treatment?

Mould returns only if the moisture source remains. We treat the surface and identify the cause, and eligible work carries warranty options. If a leak is involved, the source must be repaired to prevent recurrence.

Do I need to move out during treatment?

For most surface treatments you do not. If ULV fogging is used, we ask you to vacate the room for about two hours so the treatment can settle safely.
