PROBLEM: Specific areas with excess moisture, sometimes even mould build up.
SOLUTION: All rooms require ventilation to maintain a dry and healthy environment. Extract ventilation removes damp, stale air directly from a room. New rules require all extract ventilation to be ducted outside, so ensure any existing extract ventilation isn't going direct into your roof cavity.
