Condensation and mould in Skegness homes

Why condensation dominates on this coast

Condensation happens when warm moist air meets a surface cold enough to wring the water out of it. Every home produces moisture, from cooking, showers, drying washing and simply breathing, but the Skegness housing stock is unusually good at turning that moisture into mould.

• The off-season shutdown. A holiday let or caravan left unheated through a coastal winter cycles between damp mild spells and cold snaps. With no heat and no air movement, moisture settles into soft furnishings, mattresses and cold external corners.
• Single-storey living. Bungalows are a large share of the housing around Skegness, Chapel St Leonards and the inland estates, and they are popular with retired residents. All the moisture generated in a bungalow stays on one floor, and well-sealed replacement windows leave it nowhere to go.
• Converted buildings. Skegness has an above-average share of flats carved out of older houses and rooms over shops. Conversions often break up the original ventilation paths, leaving kitchens and bathrooms in the middle of a deep plan with no effective extraction.
• Cold coastal walls. Solid brick walls facing the sea are chilled by wind and evaporating rain, so the inside face runs colder than the room. Wardrobes and beds pushed against those walls create still, cold pockets where mould thrives.

What actually fixes it

1. Measure, do not guess The specialist looks at humidity, surface temperatures and how the household or letting pattern generates moisture. Mould washed off without fixing the cause returns within weeks.
2. Ventilation that matches the building That can mean proper extractor fans in kitchens and bathrooms, trickle vents, or a positive input ventilation unit for a whole bungalow or flat. For holiday lets, low-level background heat and controlled ventilation through the closed months matter more than any gadget.
3. Treat and redecorate once Affected areas are cleaned down and redecorated with appropriate materials after the moisture balance is corrected, so the fix holds.

For landlords and holiday-let owners

Mould complaints are now a serious legal matter for landlords, and a seasonal letting pattern is no defence if the property breeds mould every winter. A written assessment of a problem property, with the fixes costed, is a sensible first step.
