Mould in houses: causes, prevention and solutions

Mould in houses is a very real issue, yet it is a problem that often gets ignored or covered up. This means that inappropriate building work that may have caused the problem is never addressed, and so the problem continues.

Doctors have long been aware of the links between mould growth and ill health, particularly amongst the young, the elderly and people with respiratory conditions such as asthma. The case of two-year old toddler Awaab Ishak, who died in December 2020 from a severe respiratory condition caused by prolonged exposure to mould at his home in Rochdale, reminds us of just how seriously we should be taking mould growth in our homes. Yet there’s comparatively little awareness of what actually causes the problem.
