Mould on Walls or Ceilings

Mould on walls or ceilings is usually a sign that excess moisture is present within the property. While visible mould can often be cleaned from the surface, recurring growth usually indicates an underlying issue such as condensation, poor ventilation, cold surfaces, dampness or a moisture-related building defect.

What Mould on Walls or Ceilings Could Indicate

  • Condensation forming on cold walls, ceilings, window reveals or poorly ventilated areas

  • High internal humidity caused by everyday moisture, inadequate ventilation or poor air circulation

  • Penetrating damp, leaks or moisture ingress affecting the building fabric

  • Thermal bridging or cold surfaces creating conditions where mould can repeatedly develop

Why a Professional Survey Is Important

Mould should not be treated as a cosmetic issue alone. If the conditions allowing mould to grow are not identified and addressed, it is likely to return even after cleaning or redecorating. A professional survey helps establish whether the mould is caused by condensation, dampness, ventilation issues or another underlying defect, ensuring any recommendations are based on the true cause of the problem.

How We Conduct Our Surveys:

  • Identifies the root cause

  • Avoids unnecessary treatment

  • Provides clear remedial recommendations

  • Helps protect the property long-term
