What is Mold?

From a biological point of view, mold is a type of fungus. Mold can be both beneficial and harmful. However, from the point of view of our article, mold growing and causing infestations in our homes is something highly undesirable. More than just being unsightly, mold can also cause numerous problems. This includes health issues, unpleasant living conditions, and result in higher maintenance costs for property managers and owners. Mold is notorious for re-growing time and again after removal!

Mold VS Mildew

Differences of Mold and Mildew

In our article, we refer to “mold”, “mould” and “mildew” simply as “mold” because they have very similar meanings. Nonetheless, as a discerning homeowner or tenant, you would still want to know the differences. It is important to be aware of what cleaning companies are actually saying when they mention these terminologies.

The words “mold” (spelt more in this form by Americans), “mould” (spelt more in this form by British English) or “mildew” are basically referring to different types of Fungi. For the layman, mold is often referred to as a more extensive and severe type of manifestation compared to mildew. There are thousands of species of mold and mildew, and one or more of them may be growing in your house!

How do I tell the difference between mold and mildew?

One very visible difference is the color of that creepy growth you see in the bathroom. Mold growing in your house presents usually as patches of black, green or yellow. Mildew, on the other hand, is usually grey to white in color. The texture of mold is usually slimy, whilst that of mildew is powdery. Mold tend to grow deeper into structures (eg. pillar, walls, masonry or even vehicles). Mildew grow less deep and often over a large surface area faster (eg. the bathroom floor). Therefore, mold can cause more serious damage to structures whilst mildew causes comparatively more reparable damage. However, the surface area affected is not dependent on their type. Both can actually grow over huge surface areas.

Is mold removal more expensive?

Whilst mold is often considered more extensive than mildew, the removal of mold may not always be more intensive. This is a common myth amongst house dwellers and customers patronising cleaning companies. The difficulty and process of mold and mildew removal is not solely dependent on the type of fungi. The length of time, resources, and time required for mold removal depends on surface area and materials affected, types of location, and depth of manifestation.

Mold and Mildew

Similarities of Mold and Mildew

Mold and mildew are part of the family of Fungi. They feed on organic materials such as fabric (eg. clothes, carpets, curtains), leather, paper and wood (eg. carpentry, furniture) and break these things down over time. Just like other species of Fungi, mold and mildew grow best in Singapore climate. This is due to the high humidity, warm temperatures and moisture everywhere!

What causes the moldy areas at home?

As you have just read, in Singapore, the primary reason is high humidity (read: moisture, moisture and moisture!). Unsurprisingly, you would notice higher manifestations of mold when the weather has been rainy and cold. This occurs, for instance, in December to March during the Northeast monsoon season. Higher incidences of mold manifestations occur also where steam and moisture lie around due to condensation. Examples include the kitchen and toilet. For those “fortunate” enough to be living near a lake or sea (eg. Sentosa Cove), the high levels of moisture in the surroundings further increases risks of mold growing!

With the conditions aforementioned, if left unchecked, mold and mildew can grow literally limitlessly over huge surface areas. They can grow in multiple types of materials and deep into structures. Over months and years, in the worst cases, they can even break down entire walls and ceilings!

In fact, contrary to the belief of many, and perhaps a point often missed by disinfection experts too, mold can grow on almost any material in Singapore. The details of how mold can present even on “non-organic” materials such as PVCS, plastic are beyond the scope of this article, but certain reasons include the existence of special yeasts, biofilms, and how easily materials break down in Singapore’s climate.
