Mould prevention system
Stop black mould at source — without biocides, sprays or annual re-treatment.
Mould needs cold walls and condensation to grow. Our sprayed cork system removes both — raising surface temperature above the dew point so mould physically can't establish. No anti-mould paint, no chemicals, 25-year warranty.
The science
Three things grow mould. Remove one — permanently.
Mould spores are everywhere — they always have been. What turns a harmless airborne spore into a colony of black mould on your bedroom wall is the combination of a food source (any organic dust on paint), moisture (condensation), and a cold surface (below the dew point of the room air).
You can't sterilise the air. You can't stop people breathing and showering. But you can warm the wall — and that single intervention breaks the cycle for good. That's the entire principle behind a sprayed cork mould prevention system.
Where it works
Bedrooms, bathrooms, behind wardrobes, kitchen extensions.
Domestic: chronic mould patches on north-facing bedrooms, return walls behind wardrobes, window reveals, the cold corner of a new kitchen extension, ground-floor flats with party-wall cold-bridging.
Landlords & social housing: a permanent fix to Section 11 disrepair claims and Awaab's-Law obligations. One sprayed cork application typically outlasts five anti-mould repaint cycles — and the tenant complaint stops with it.
Why landlords and homeowners choose it
A real fix, signed off with a 25-year warranty.
Removes the cold surface
Wall surface temperature lifted 4–6°C — out of the mould growth zone.
Class 1 breathable
Existing wall moisture dries outward — nothing trapped, nothing rotting behind.
No biocides, ever
Pure physical fix. Nothing to deplete, nothing to re-apply, nothing to reformulate.
Safe for occupied homes
Low-VOC, non-toxic, certified for nurseries, schools and healthcare interiors.
Decoration-ready in 48 hrs
Paint over with breathable mineral or silicate paint, or leave as a textured finish.
25-year warranty
One application replaces decades of anti-mould repaint cycles and tenant disputes.
Mould prevention FAQs
What homeowners and landlords ask.
- What actually causes black mould on internal walls?
- Black mould (most commonly Aspergillus and Cladosporium species) needs three things to grow: a food source (any organic dust on a painted wall), moisture, and a surface temperature below the dew point of the surrounding air. Remove any one and the mould stops. Cork removes the cold surface — the easiest and most durable lever to pull.
- Is black mould actually a health risk?
- Yes. The NHS, World Health Organization and UK Housing Act all recognise persistent indoor mould as a respiratory hazard — particularly for children, the elderly, asthmatics and the immune-compromised. The 2022 Awaab Ishak inquest made the legal duty on landlords to act explicit.
- How is cork-based mould prevention different from anti-mould paint?
- Anti-mould paint adds a biocide to the surface that suppresses spores for 6–12 months. Then it depletes and the mould returns because the wall is still cold. Cork removes the cold surface itself — the mould has no liquid water to germinate on, so it can never establish. Permanent fix, not a chemical treatment.
- Does the cork coating contain biocides or chemicals?
- No. It's a water-based natural cork suspension with a binder. Low-VOC, non-toxic, no off-gassing — certified safe for occupied homes, nurseries, schools and healthcare. The mould prevention is purely thermal and physical.
- Can it be installed in occupied homes?
- Yes. Single rooms are completed in 1–2 days with minimal disruption. We mask, prep, spray, leave to cure — the room is decoratable within 48 hours. No need to move out.
- Will it stop mould in bathrooms and kitchens too?
- Yes — provided ventilation is adequate to manage steam at source. Cork dramatically reduces surface condensation, but a bathroom without an extractor will still generate enough vapour to cause issues. We assess ventilation as part of every survey.
