We specialise in fitting cavity trays which is often overlooked, but essential in keeping conservatories and extensions water tight when extending an existing house or created a new build.
Cavity tray’s are preformed damp proof courses placed at the lintel of a door or window, which allow moisture to escape through weep holes. It is a barrier put above a window or door opening to deflect moisture that transfers across the outer leaf of brickwork back to the outer face. This is rather than allowing it to cross the cavity at lintel level causing dampness internally.
