Gap between house and decking
How much of a gap should there be between the house and decking (issues with damp on adjacent wall)?
The gap between decking and wall only needs to be big enough to allow timber to swell and shrink through weathering, however if the decking is covering your air bricks this may cause problems as the decking should be no higher than 2 bricks below damp corse, in some cases it's okay to go higher dependant on the deck frame structure.

Hello yes it would be better if you can do it 150Mm down from the DPC but a gap of 15mm would be fine
