What the work involves
Ventilation is usually the biggest part of the cure, but not the only part. Heating patterns, insulation gaps and cold bridges matter too, and some damp is not condensation at all: leaks, penetrating damp and rising damp need different trades.
Mould treatment advice
How to clean and treat affected areas once the cause is fixed.
Survey and findings
Humidity and surface readings, existing fans flow-tested, and a written list of causes and fixes.
