Loft Mould Treatment in Sheffield

Targeted mould treatment in a detached house loft with chimney

Mould & condensation treatment Detached house Sheffield
Professional mould treatment being applied to loft roof timbers in Sheffield

What we found

  • Extensive black mould growth on roof boarding around the chimney
  • High humidity due to limited ventilation and seasonal condensation
  • Dust and insulation restricting air movement near the eaves
  • Risk of mould spores spreading into the living space

The problem

The homeowner noticed a musty odour and dark mould patches on the loft boarding, particularly around the chimney breast and on the north-facing roof slope. Left untreated, this can damage timbers, reduce insulation performance and affect indoor air quality.

Our assessment

We carried out a full loft inspection, moisture readings and a ventilation check. The loft had minimal airflow and elevated moisture around the chimney and eaves. Roof boarding was structurally sound but showed widespread surface mould.

The treatment

We safely applied a professional biocide treatment to all affected roof boards and timbers, focusing on high-risk areas around the chimney and eaves. The treatment kills mould at source and provides long-lasting protection against regrowth.

The result

Mould has been eliminated at source and the treated areas are protected against future growth, helping to maintain a healthier loft environment and protect the home.

The treatment helped to

  • Eliminate existing mould and spores
  • Protect timbers and roof boarding
  • Improve indoor air quality
  • Support better energy efficiency
  • Provide long-term peace of mind
