Loft Mould Treatment in Southampton

Mould treatment and ventilation checks in a low-pitched bungalow loft

Mould & condensation treatment 1960s detached bungalow Southampton
Professional mould treatment being applied to loft roof timbers in Southampton

What we found

  • Extensive black mould growth across the underside of the roof lining
  • Condensation staining and damp spots throughout
  • Inadequate ventilation for the loft volume
  • Insulation in good condition but moisture affected in places

The problem

The homeowner noticed a musty smell in the loft and black spotting on the roof lining. They were concerned about the health implications and potential long-term damage to the property.

Our assessment

The loft had poor airflow due to limited eaves ventilation and a tightly sealed roof construction. Warm, moist air from the home was condensing on the cold roof lining, creating the ideal conditions for mould growth.

The treatment

We applied a professional biocide treatment to all affected roof lining areas using low-pressure application equipment. The biocide kills mould spores at the source. We treated timber rafters where required.

The result

Active mould was successfully removed and treated. The loft is now clean, fresh and protected. Ventilation has been improved to help maintain a dry, healthy environment and prevent future issues.

The treatment helped to

  • Eliminate active mould and prevent regrowth
  • Improve indoor air quality
  • Protect the roof structure and insulation
  • Reduce the risk of respiratory irritation
  • Support a healthier home environment
