Loft and attic mould removal across Yorkshire
Mould in a loft usually means warm, moist air from the house is condensing on cold felt and timbers; roof leaks are another cause. We clean and treat affected surfaces, then look at ventilation, insulation and leaks so it is less likely to come back.

The longer you leave it, the worse it gets
Black mould spreads through walls, ceilings and clothing, and the spores can make breathing problems worse.

Why lofts get mouldy
Common causes are blocked soffit vents, insulation pushed into the eaves, bathroom fans venting into the loft and missing loft-hatch seals. A roof leak can look similar, so we inspect before recommending anything.
Treating rafters, joists and felt
Most loft mould can be cleaned and treated in place. We only suggest replacing timber or felt where it is genuinely rotten or torn, and we show you photos before any extra work.
Loft mould and house sales
Surveyors often flag loft mould. Buyers want to know what caused it and what's been done about it, so we explain the cause and the ventilation or insulation changes alongside the clean.

Common questions
Is loft mould dangerous?
The loft is separate from living space, but heavy growth means moisture is getting up there — the same moisture often causes mould in bedrooms below.
Do I need new felt or timbers?
Usually not. We only recommend replacement where material is rotten or torn.
