Many moulds can appear dark, and exposure effects vary between people. Mould can irritate eyes and airways and aggravate asthma. People with weakened immunity or chronic lung disease should seek medical advice about their particular exposure circumstances.
Dry brushing, sanding or scraping can disturb spores and spread dust. Avoid covering the problem with paint or repeatedly applying household products without investigating the moisture source. Larger, recurrent or hidden problems deserve a planned assessment.
We discuss the work area, material removal and cleaning method before treatment. If a ceiling stain follows rain or a bathroom patch returns after cleaning, associated repairs and ventilation changes may be needed alongside removal.
Questions about black mould treatment
Is all black mould toxic?+
No. Colour is not a reliable way to identify a mould species or determine toxicity. Visible mould of any colour and persistent damp should be addressed.
Should I stay in the room?+
The appropriate precautions depend on the extent of growth, work planned and the occupants' health. Avoid disturbing it. If someone has breathing symptoms or particular vulnerability, ask a healthcare professional for advice.
