- 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.
- 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.
