Black mould removal
Professional black mould removal combined with investigation of moisture, ventilation and cold surfaces.
Why diagnosis matters
Treat the cause, then repair the damage
Visible mould can be treated safely within an agreed work area, but removal is only one stage. The conditions supporting growth must also be reduced to limit recurrence.

Common questions
About black mould removal
Can I clean black mould safely?+
Small areas may be manageable with appropriate precautions, but recurring, extensive or uncertain growth should be assessed before repeated cleaning.
Why is it behind furniture?+
Air movement is restricted and the external wall may be colder, allowing surface humidity to rise.
Will it come back?+
Recurrence risk remains if humidity, cold surfaces, leaks or ventilation problems are not addressed.
