Condensation & Mould Treatment in Whitchurch
Condensation is the most common form of damp in UK homes and a major cause of black mould growth. It occurs when warm, moisture-laden air meets cold surfaces. In South Wales, where older housing stock and wet winters combine, it is especially prevalent. Black mould (Aspergillus/Cladosporium) produces spores that can trigger respiratory problems, asthma, and allergies — making rapid treatment essential. EverDry Damp removes existing mould growth with specialist fungicidal treatments, then addresses the root causes through improved ventilation and anti-condensation coatings.

Frequently Asked Questions — Condensation & Mould in Whitchurch
Is black mould dangerous?
Black mould produces mycotoxins and spores that can cause respiratory problems, worsen asthma, and trigger allergic reactions — particularly in children, the elderly, and those with existing health conditions. It should be treated promptly.
Will a Positive Input Ventilation (PIV) unit solve condensation?
PIV units are highly effective for whole-house condensation problems. They introduce a constant supply of filtered, slightly warmed air from the loft, gently pressurising the home and pushing moisture-laden air out through natural gaps.
Can I paint over black mould?
No — painting over mould is a temporary cover-up. The mould will grow back through ordinary paint within weeks. Mould must be treated with a fungicidal solution, killed at the root, and the underlying cause (condensation) must be addressed.
