What the work involves
Mould needs that damp surface to grow. Ventilation is usually the biggest part of the cure, but not the only part.
Survey and findings
Humidity and surface readings, existing fans flow-tested, and a written list of causes and fixes.
Fan upgrades
Weak or loft-vented fans replaced and ducted outside, with humidity control.
