Breathe Easier in Suffolk, Norfolk & Essex

Condensation is the most common form of damp in UK homes. It occurs when moisture-laden air hits cold surfaces like windows and external walls, leading to water droplets and, eventually, unsightly and unhealthy black mould growth.

Simply wiping away the mould or painting over it doesn't solve the root cause. At KDS, we improve your home's air quality and ventilation to cure condensation for good.

The Science of Ventilation

Modern homes are sealed tight to keep heat in, but this also traps moisture from cooking, showering, and breathing.

Humidity

High humidity encourages dust mites and mould spores, known triggers for asthma and allergies.

PIV Units

Positive Input Ventilation (PIV) gently pushes fresh, filtered air into the home, forcing stale, damp air out through vents.

Heat Retention

Dry air is cheaper to heat than damp air. By reducing humidity, you can actually lower your heating bills.

Finding the source of moisture

How can condensation be distinguished from a leak?

Condensation often forms on cold surfaces and may be more noticeable in colder weather, while a leak or rainwater ingress can create a persistent, localised patch linked to plumbing or rainfall. These clues are not definitive: several causes can overlap, and salts may remain visible after a source has stopped. Record when the area changes and where it appears; if the cause is unclear, a building assessment is preferable to treating the surface alone.
