An Overview: Exploring the Process of Mould Assessment

The prevailing high humidity levels and the tropical climate in Singapore have created conditions ideal for mould growth, posing challenges for businesses and individuals, including hygiene concerns and health risks. Mould assessment becomes essential in maintaining a healthy indoor environment when dealing with mould issues. Let’s delve into the specific steps of the process.

1. Initial Inspection

A meticulous initial mould inspection serves as a foundational step in identifying potential problem areas. With moisture meters, thermal imaging cameras, and other equipment, professionals can detect visible mould, assess water damage, and locate areas prone to moisture accumulation. As such, mould problems can be identified earlier, before they worsen.

2. Visual Inspection

Visual inspection is one of the key components of mould assessment, providing valuable information about the building’s condition and potential areas of concern. It allows one to uncover visible signs of moisture, leaks, and mould growth, assisting professionals in determining the scope of the assessment and the need for further testing or remediation.

Mould Professionals

  • General Visual Inspection Practices

Mould often produces a musty odour. During an inspection, mould removal experts will first try to locate any unusual or mouldy odours in different areas of the building. If there are water stains on walls, ceilings, or floors, these professionals will focus on these areas for close examination in case mould growth is present.

  • Exterior Inspection

Mould removal professionals will examine the building façade to identify potential water entry points, such as damaged roofs, windows, or siding.

  • Interior Inspection

A thorough visual inspection of the interior spaces is conducted, prioritising areas prone to moisture, such as basements, crawl spaces, bathrooms, and kitchens.

3. Moisture and Humidity Measurement

Mould spores, which are commonly found on walls, ceilings, and other hidden spaces, require specific conditions to grow and proliferate. High humidity levels, typically above 60%, make it ideal for mould to flourish. Additionally, dampness in building materials, caused by water leaks, condensation, or humid weather, also promotes mould growth. By considering these factors, specialists in mould removal can tailor remediation strategies to rectify mould issues effectively.

4. Thermal Imaging and Moisture Detection

Thermal imaging and moisture detection are advanced techniques for tracking down areas affected by mould. Thermal imaging, known as thermography, relies on infrared technology to detect surface-level temperature differences. It uncovers hidden moisture and potential mould growth by highlighting cold spots on thermal images. However, it's important to note that thermal imaging is approached on a case-by-case basis, particularly if signs of moisture are evident. Not all areas will be inspected using this application. On the other hand, moisture meters play a crucial role in assessing the moisture content of materials such as drywall, wood, or insulation. Professionals will insert the meter into the material to obtain accurate readings. Elevated readings are indicative of moisture problems that may lead to mould problems.

5. Detailed Assessment Report and Recommendations

The creation of a detailed report marks the last step of the mould assessment process. This document provides an overview of the findings, including identified mould types, the extent of contamination, and recommended remediation strategies. At STERNG, we are committed to ensuring reporting transparency, keeping our clients well informed and equipped to make sound decisions about mould remediation.

Performing mould assessment correctly is a vital step towards ensuring a healthy indoor environment. From the initial inspection to the detailed assessment report, proactive measures should be taken to safeguard both your property and your well-being.
