Case study
Loft Mould Treatment in Sheffield
Targeted mould treatment in a detached house loft with chimney
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
