How to prevent mould growth after flood damage?

A persistent accumulation of water from leaks or floods in your home can lead to the growth of mould. Various household items such as carpets, books, upholstery as well as walls that were submerged in flood water or otherwise remained wet for a significant length of time are at a high risk of mould infestation.

The growth of mould is a common occurrence everywhere after the events of flooding. The spores of mould can cause serious health hazards. Apart from that, the mould itself can cause long-term damage to your house and furniture.

In this article, we will discuss the various ways in which you can preemptively prevent the growth of mould after flooding so that you do not have to deal with any health hazards or property damage. Without further ado, here is our step by step guide for the thorough prevention of mould growth:

1. Quick extraction of flood water

Prevention of mould growth requires quick action on your part. The longer the water gets to soak through into your belongings, the higher the chances of mould buildup. If the flood water level is low or only a few centimeters high you can quickly sweep it out using a mop. If the flood water level is more than a foot high, you could use either buckets or an electric pump for the quickest and the most effective extraction of flood water.

2. Removal of undamaged articles untouched by water

Mould growth usually occurs within two days of flooding and persistent water accumulation. In order to ensure prevention of further carpet water damage and containment of mould risk, you should relocate all the still dry items in your house to a safe and dry environment.

You should carry out the removal of water and relocation of dry undamaged items within the first day itself. Then start with the next step of cleaning and drying of water damaged items within the following day to ensure the best shot at preventing mould growth.

3. Dehumidification and ventilation

To fasten the process of water extraction from wet items, open all the windows and doors to ensure maximum airflow and ventilation. Along with the removal of floodwater, fighting mould growth also requires you to ensure the extraction of moisture from the surrounding air.

Mould thrives in the humid atmospheres induced by floods. You will have to rent industrial dehumidifiers and fans to dry out the moisture-laden air. These suck the humidity out of the air to ensure quicker drying of wet and flood water affected furniture and upholstery.

4. Decontaminating and drying of affected items

After removing the flood water and dehumidifying the air to ensure quicker drying of wet surfaces, the next step is to decontaminate the house and damaged articles. Thoroughly clean the floor with strong cleaning agents to ensure removal of any contaminants that may linger. You should also replace any ceiling tiles as well as the lower sections of drywall that may exhibit clear signs of water damage.

Walls and ceiling tiles also need to be cleaned so as to not allow mould to grow in cavities and narrow openings. Carpets and upholstery require thorough washing and drying to prevent any chances of mould growth. Rugs that have had their padding damaged or have been wet for a while need to be replaced to prevent further growth and spread of mould to other items.

Carefully abide by the aforementioned instructions and follow the process with a period of vigilant monitoring of affected areas and items to ensure prevention of any mould growth. If you notice persisting mould formation, you should immediately enlist professional assistance for mould remediation.
