What the work involves
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. We tell you if that is what we find rather than selling a fan that will not help.
Fan upgrades
Weak or loft-vented fans replaced and ducted outside, with humidity control.
Whole-home ventilation
PIV, continuous extract or MVHR where moisture is spread through the house.
