The death of a 15-week-old baby who lived in a Camden flat, managed by housing association Notting Hill Genesis, led to a protest outside its headquarters on Friday.
Akram Mohammed died in February and his parents believe damp and mould contributed to their son's death. They said "no one helped" from the housing association, after repeated requests for repairs.
Patrick Franco from the organisation said: "We know this is a complex situation and will continue working with the relevant authorities as they conduct their investigations."
An inquest, opened by St Pancras Coroner's Court, into the baby's death has been adjourned and is due to conclude later this year.
