Restoring safety when mould takes hold

Mould is more than just a cosmetic issue, it can damage building materials, affect air quality, and trigger allergic reactions or respiratory problems. Whether mould appears on walls, ceilings, floors, or behind surfaces, fast intervention is essential.

We use certified specialists and proven methods to tackle mould in private homes, commercial buildings, and industrial facilities. From small outbreaks in bathrooms to extensive growth hidden in structures, we have the skills and tools to deal with mould of any size.

The process

Inspection and assessment

We inspect visible mould, test air quality or surfaces, and determine the extent of growth and underlying moisture sources.

Containment and isolation

We protect unaffected areas, set up barriers, and use air filtration to stop spores spreading.

Removal and cleaning

Mould-damaged materials are safely removed or cleaned, surfaces are treated and disinfected, and replacements made where required.

Drying and moisture control

We ensure the underlying moisture problem is resolved through drying and by addressing leaks or high humidity.

Final verification and clearance

After remediation, we test air or surfaces to verify mould has been fully removed and the environment is safe.
