What the surveys describe

A Brighton survey item for the Uniting Church and Hall at the property on Brighton Road recommends: The replacement of coping render, particularly to the front roof gable is recommended to prevent water penetration and deterioration of brickwork. The Unley study notes of the property on Young Street, Parkside: The brick quoining and door dressing appear to be alternating white and red brick, although this could be painted. Both are descriptions at survey time, not advice on any wall.

Ask the provider what coating or render the quote uses and what it does to moisture in the wall.
