Can anyone advise on the best way to clear out a bridged cavity?. Should you remove just one brick from the external wall at a time, or is it ok to remove several, to give better access?.

[tucny]

remove one miss say two then remove another. do this to say a two meter section at a time and replace bricks before moving on.

Thanks tucny!. When you say about 2 metres, do you mean 2 square metres ie. remove the bricks bith horizontally and vertically?

[tucny]

horizontally, say the second course above the dpc. Im assuming that you want to make sure there isnt any debris in the cavity that could bridge the dpc?

That's correct -thanks again tucny!
