Case study
Loft Mould Treatment in Leeds
Condensation-related mould treatment in a Victorian terrace loft
What we found
- •Widespread black mould across the roof boarding
- •Caused by long-term condensation and poor ventilation
- •Heaviest growth on the north-facing roof slope
- •No active roof leaks detected
- •Insulation in place but ventilation was inadequate
The problem
The loft had persistent musty odours and visible mould spreading across the roof timbers and boarding. Condensation was forming due to warm, moist air rising from the home and inadequate ventilation.
Our assessment
Our survey confirmed the mould was surface growth caused by excess moisture. We checked the roof for leaks, assessed ventilation and insulation levels, and recommended a professional biocide treatment with improved ventilation.
The treatment
We applied a professional-grade biocide to affected roof boards and timbers using low-pressure spraying equipment. The solution penetrates the surface to kill mould at source and help prevent regrowth. We also advised on maintaining good ventilation to control future moisture.
The result
The mould was treated effectively, leaving the loft clean, fresh and protected. With improved ventilation and ongoing moisture control, the loft is now in a much healthier condition.
The treatment helped to
- Eliminate existing mould at source
- Reduce musty odours
- Improve indoor air quality
- Protect roof timbers and boarding
- Help prevent future mould regrowth
- Create a healthier loft environment
- Support the long-term condition of the property
