If the mould is caused by a structural issue — leaks, rising damp, inadequate ventilation — it's the landlord's responsibility. If it's caused by tenant lifestyle (not ventilating, drying clothes indoors with windows sealed), it gets more complicated. Our assessment report documents the root cause, which helps settle the question.

Yes, particularly for people with asthma, allergies, or weakened immune systems. Mould releases spores that cause respiratory irritation, allergic reactions, and in severe cases can lead to fungal infections. Black mould (Stachybotrys) produces mycotoxins that are especially harmful with prolonged exposure.

Not if the root cause is fixed. If you remove the mould but don't address the moisture source — the leak, the condensation, the poor ventilation — it will return. That's why our approach includes prevention advice and root cause identification, not just surface treatment.

Both. We remove the existing contamination and identify the moisture source driving it. We'll make recommendations for fixing the cause — whether that's improving ventilation, repairing a leak, or upgrading extraction. If the fix requires another trade, we'll tell you exactly what's needed.

A single room typically takes half a day to a full day. Larger jobs involving multiple rooms or material removal can take 2-3 days. We'll give you a clear timeline after the initial assessment so you can plan around it.

Yes. We provide free initial assessments for properties across South Wales. We'll visit, identify the issue, and give you an honest recommendation — including telling you if it's something you can handle yourself. Call 07350 136763 to book.

No — and this is one of the most common mistakes we see. Painting over mould traps it beneath the surface where it continues to grow. Anti-mould paint has its place as a preventative measure after proper treatment, but it's not a substitute for removing the contamination and fixing the moisture source.
