Why Choose Mold Detection SA?
Unlike companies that simply remove visible mould, we investigate the
underlying causes of mould growth. Johannesburg’s seasonal
thunderstorms, ageing buildings, waterproofing failures, plumbing leaks,
rising damp and poorly ventilated indoor environments frequently create
conditions where hidden moisture and mould can develop. Our objective is
to identify exactly why mould developed, where the moisture originates
and what is required to permanently resolve the problem.
✓ Identify why mould developed
✓ Locate hidden moisture, dampness and water ingress
✓ Assess whether indoor air quality has been affected
✓ Determine occupant exposure to airborne mould spores
✓ Evaluate humidity, ventilation and condensation problems
✓ Provide clear remediation recommendations
Specialists in Johannesburg’s Complex Building Environment
Johannesburg presents a wide range of moisture-related building problems across older homes, modern estates, apartments, office buildings, schools, medical facilities and industrial properties. Seasonal heavy rainfall, roof and gutter failures, defective waterproofing, plumbing leaks, rising damp and poorly controlled indoor humidity frequently contribute to hidden mould growth and compromised indoor air quality.
Our investigations identify the true source of moisture intrusion, whether caused by roof leaks, rising damp, plumbing failures, waterproofing defects, stormwater penetration, poor ventilation or excessive indoor humidity, allowing effective long-term remediation rather than temporary cosmetic cleaning.
Independent scientific investigations that identify the source of the problem — not just the visible mould.
