Mould removal that identifies why it is growing.

Poor airflow allows humid air to remain trapped inside the room. This is common in enclosed bedrooms, wardrobes, storerooms and indoor laundry areas where moisture cannot escape.

Warm, humid air meeting cold ceilings, walls or air-conditioning surfaces creates condensation. This is one of the most common causes of recurring mould in Singapore homes, even when there is no plumbing leak.

Hidden pipe leaks, bathroom seepage, roof leaks and external wall penetration can introduce continuous moisture that feeds mould behind paint, ceilings and built-in furniture.

Many homeowners don't realise that incorrect air-conditioning settings, poor airflow or condensation around fan coil units can contribute to recurring mould growth.

Singapore's tropical climate means indoor humidity can remain high for long periods. When humidity stays elevated (above 60%), mould can begin growing on walls, ceilings, wardrobes and other surfaces.

A fast spread usually means humidity has stayed high for a stretch, often during rainy periods, or a new moisture source has started such as an aircon leak, wall seepage or poor airflow after renovation. When mould appears quickly in several places, it is worth checking for a hidden cause rather than only wiping the surface.

It usually depends on the tenancy agreement and the cause. Everyday ventilation and drying is normally the tenant's part, while damp from leaks, seepage, aircon faults or building defects is often the landlord's. We provide a written assessment that identifies the moisture source, which both sides can use to sort out responsibility. We are not lawyers, so for any dispute please refer to your tenancy agreement.

We remove it at the source and treat the surface, then finish with long lasting protection, so it does not simply return under a coat of paint.

Ceilings, walls, bathrooms, bedroom corners, wardrobes, aircon areas, kitchens and service yards, in HDB flats, condos and landed homes across Singapore.

Most residential mould jobs range from $250 to $2,500 or more, depending on the size of the affected area, the severity, the location and whether anti-mould painting or odour treatment is needed. You will always know the price before we start.

Not when it is treated properly. We address the moisture at the root and apply a protective coating, so the area stays clear, rather than just hiding the stain.

Mould spores affect indoor air quality and can trigger allergies and respiratory issues, especially for children, the elderly and anyone with sensitivities.

Ceiling mould usually signals hidden moisture such as aircon condensation or a leak. Left untreated it spreads and damages finishes, so it is best assessed early.

Most residential jobs are completed in a single visit. Larger or more severe cases may need additional time or a follow-up.

Surface cleaning removes the stain but not the spores or the moisture behind it, so it returns within weeks. We treat the root cause so it stays gone.

Yes, Four Solutions is NEA Vector Operator Licensed, Reg. NEA201812722M, with 10 years serving Singapore.

It can include mould removal and surface treatment, anti-mould protective coating for 3 to 6 months, odour and indoor air quality treatment, booklice or pest support where needed, and root-cause checks for moisture.

We treat ceiling mould, bathroom mould, bedroom walls and corners, wardrobes and cabinets, aircon condensation areas, kitchens and service yards.

We use professional UV checks, moisture measuring tools, relative humidity readings and thermal scanning to identify high-risk damp areas, likely moisture pathways and hidden mould risk beyond visible stains. Tools guide targeted checks; where access is limited, the assessment identifies risk rather than promising to see through every wall or ceiling.

Common causes include poor ventilation, condensation from aircon and trunking, seepage, leaks, flooding, indoor laundry, high humidity and damp items stored against walls or inside cabinets.

Yes. Where needed, we provide premium odourless anti-mould painting works after mould removal and treatment, so the surface is protected rather than simply painted over.

Where needed, we use disinfecting fogging to reduce odour and deactivate airborne mould spores after removal, helping prevent cross-contamination of nearby areas.

Warranty options can be discussed after assessment. Depending on the scope and finishing system, 6 month, 12 month and 24 month options may be available.

Yes. Existing Four Solutions mould clients can ask us about current Novita dealer pricing and promotions after treatment, especially for enclosed rooms, wardrobes and indoor laundry areas.

Enclosed wardrobes trap humidity around leather, which is why bags, shoes and belts grow a fuzzy mould in Singapore's climate. Keep the space ventilated, use a dehumidifier or fresh desiccant, and avoid packing items tightly. If mould keeps returning across the wardrobe, there is usually a wider humidity or wall-damp issue, and we can treat the space and advise on control.

It is more common than people expect. New screed, plaster and paint hold construction moisture for months, and sealed-up rooms with new aircon can build condensation. Early mould in a new flat usually points to trapped moisture or ventilation, not neglect. We assess the cause so it is fixed before it spreads into new finishes and built-in carpentry.

A dehumidifier helps keep humidity down and slows new growth, but it does not remove mould that is already there or fix a leak feeding it. Think of it as prevention, not a cure. We remove the existing mould at the source, then advise where a dehumidifier or better airflow genuinely helps keep it away.

Painting over live mould traps it and it bleeds back through within weeks. Anti-mould or anti-condensation paint only works once the growth is removed and the surface is treated and dry. We remove and treat first, then apply protective anti-mould coating, so the finish lasts instead of staining again.
