checking that the cavity between the two walls is suitable for filling
marking out existing ventilation points, wiring and pipework
loading insulating material – wool, foam, granules, fibreglass or bead – into the van and driving to the site
using a hand-held drill, pneumatic or electric, to bore a set pattern of holes in the wall, drilling from the outside in old buildings and from the inside in new buildings
operating a machine to pump or blow the insulating material into the cavity between the walls
checking that you have filled the whole cavity
repointing the drill holes to match the existing external mortar and cleaning up
fitting loft insulation and lagging pipes and tanks.
