A flashing and weep apparatus allows for simple installation and accurate placement windows and doors in cavity wall construction. In a first embodiment, the flashing and weep apparatus is a two-panel extrusion that has a flashing panel that acts as a non-porous support for the masonry veneer. This embodiment also includes a second panel which is joined at a generally right angle to the first panel to be juxtaposed against the outer face of the inner wall in the cavity wall construction. Weep channels are formed between the two panels and allow for the drainage and dissipation of water and other moisture in the cavity wall system. In a second embodiment, membrane is initially attached to and draped along the lower portion of the inner wall immediately above the sill or lintel.
