Content: take advice from a structural engineer on the type and strength you need. Some tips specific to small openings are given here, but the techniques for supporting the wall and cutting the opening are those shown above. For small openings in brickwork — no wider than 3 feet, for example — it may be possible to cut the opening without temporary support. If any bricks fall out of their positions, they can be replaced after the header is set in place. With blockwork, however, it is almost always necessary to use a temporary support. If you need to cut into an exterior cavity wall for a new window or a doorway, use a cavity wall header. This will provide support while retaining the cavity wall's damp-proofing function. It directs any moisture in the cavity out though weep holes in the wall. Your structural engineer will specify the strength to use. Close off the cavity at the sides of the new opening, either using cavity closers or by laying blocks.
