There is no gap between the bottom of the cladding and a window/door head flashing (gap should be 5 mm)

Cause

It was not installed correctly when constructed – the gap has been required under E2/AS1 for building work since 1992 to allow draining and drying from behind the cladding

Repair

  • the omission of the gap may have a significant impact on the long-term performance of the cladding system. Engage an experienced building surveyor to report on the lack of the gap and the repair options available
