We need a few things done on the exterior of our detached house to improve a few issues caused by poor workmanship in the past and prevent damp issues from occurring:

• Break concrete and lower ground level on one side. The ground here is in a narrow passageway between one of the house walls and another wall, so it's a bit tight.

• Raise the rendering around most of the house. Currently there is no bell cast around most of the building and the rendering extends right down to the ground.

• Install airbricks along one side of the house (in the small passage) and ensure all current airbricks are in effective locations, or replace.

• Possibly trim back decking in back garden to prevent water splashing up against walls. This might not need to be done if removing the render leaves enough room for water to escape between the decking and wall.

• Investigate downpipe and ensure water is draining away from the wall.
