Condensation Control in South Wales
Practical solutions to reduce moisture and improve airflow.
What the work involves
Mould, streaming windows and musty rooms diagnosed properly.
Black mould around windows, in corners and behind furniture is usually moisture from everyday living settling on cold surfaces, not rising damp.
We survey free of charge, find where the moisture is coming from, and recommend the right fix — usually better insulation and ventilation.
