Mould Removal & Remediation near you in Ireland

For a small visible patch, no — you can see it. Testing matters when mould is hidden, health issues are involved, or you need documentation for a dispute or insurance. Use an independent tester, not the company doing the removal, to avoid a conflict of interest.

Surface mould on a hard, non-porous wall can be a clean-and-treat job. Once it is into plaster, drywall, insulation or timber, proper remediation means removal, containment to stop spores spreading, and drying — cleaning alone lets it return.

Small surface patches are cheap to treat, but priced jobs scale with the affected area and whether the underlying cause is fixed. Most single-room remediations land in the mid three to low four figures; whole-home jobs needing containment and HVAC cleaning cost several times more. Repairing the moisture source is often a separate line.

A patch smaller than about a square metre on a hard surface is a reasonable DIY job with protection and ventilation. Larger areas, porous materials, or anyone with respiratory sensitivity should bring in a professional with containment.

Sometimes — if the mould resulted from a sudden covered event like a burst pipe, insurers may pay. Mould from long-term neglect or condensation is usually excluded. Document the cause and keep remediation reports if you intend to claim.

Some moulds produce irritants and allergens that affect breathing, and vulnerable people react worse. Colour alone does not determine toxicity, but extensive growth is a reason to use containment and proper protection rather than scrubbing it yourself.

Because remediation without fixing the moisture source is temporary. Leaks, rising damp, condensation and poor ventilation must be corrected first — any quote that treats the mould but ignores the cause is only buying you a few months.

A single room typically runs €500-€1,500 and a whole property from €1,500 upward, with small surface treatments from around €180. Fixing the damp cause is usually a separate cost.
