Project specification

  • Following the introduction of Awaab’s Law, we were instructed by a social landlord to inspect a sample of housing stock that the residents had said were subject to mould, damp and condensation problems.
  • The landlord has already treated the mould and arranged remedial works in these properties; they now wanted to assess if those works had been successful at stopping the problem recurring.
  • The surveys involved:
    • inspecting the condition of the property
    • assessing the levels of ventilation and insulation
    • assessing the residents’ use of heating
    • investigating the causes of damp
    • air quality tests.

Key points

  • In most cases, the mould and the causes of mould had been resolved.
  • In houses where mould was still present, it was rarely caused by the behaviour of the residents.
    • In a few cases, we found that residents were under-using their heating because of concerns over the costs.
    • Some had also blocked up trickle vents and turned off extractors to stop the noise.
  • In most cases where mould and damp were present, this was due to ventilation and insulation defects.
    • We found broken presusre ventialtion systems, and detatched ventilation ducting that was discharging warm, moist air into roof areas.
    • We also found damaged loft insulation, leading to condensation on ceilings.
