Condensation & mould control
Black mould in the corners, streaming windows, a damp smell that won't shift? That's usually condensation — and it's very treatable once you tackle the cause.
What causes condensation?
Condensation happens when warm, moist air inside the home meets a cold surface — a window, an external wall, a cold corner — and the moisture turns back into water. Modern living produces a lot of it (cooking, showering, drying clothes indoors), and well-sealed homes with poor ventilation trap it. Over time that moisture feeds black mould and can be mistaken for rising damp, which is why an accurate diagnosis matters.
Signs and symptoms
- Black spot mould in corners, on ceilings, behind furniture and around windows
- Water running down or pooling on window panes and sills
- A persistent damp, musty smell
- Damp patches on cold external walls, worse in winter
- Peeling wallpaper and damp-feeling soft furnishings
How we treat it
Because condensation is about moisture-laden air meeting cold surfaces, the solution is usually improved ventilation combined with treating the mould already present. Depending on the property that can mean extractor fans, passive or positive-input ventilation, and advice on managing humidity day to day. We remove and treat existing mould so it doesn't simply return, and we'll always rule out rising or penetrating damp first.
What to expect
We begin with a free, no-obligation survey to confirm it really is condensation and identify why it's happening, then recommend a proportionate solution with a clear written quote. Practical, honest advice — no unnecessary work.
