Condensation and mould fixes for Sevenoaks homes
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.
Whole-home ventilation
PIV, continuous extract or MVHR where moisture is spread through the house.
