Gap between bottom of cladding and head flashing sealed
The gap between the bottom of the cladding and a window/door head flashing has been sealed (gap should be 5 mm)
Causes
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
- remove the sealant from the joint (sealant can be left where the window head flashing has been notched into the cladding)
