STEP 1 Remove old bolts supporting centre post. Using hammer drill fitted with 10mm masonry bit, drill through existing holes into bricks. If old bolts do not come out easily, leave in place and drill a new hole.
STEP 2 Tap in new bolts using a hammer, then tighten bolts using an adjustable spanner.
STEP 3 Make gate square by checking diagonals and adjusting until they are equal. Support gate by cutting a new timber brace from 90 x 45mm treated pine to run from bottom of gate on the hinge side, to the top of gate on the latch side. Cover brace with 2 coats of outdoor paint, allowing to dry between coats. Slot brace into gate, then screw through side into the brace to secure.
Step 4 Remove old latch. Attach new galvanised latch using longer screws to get better grip into the existing timber.
