Porous Chimneys Cause Thatch problems

There is no logical explanation as to why some chimneys suddenly become porous chimneys.

Often the Thatch Owner will assume it is a problem with the thatch or the flashing and the time taken to find the real problem can be distressing.

In this case, this Chimney became porous and as the Thatch Owner never used it we took it down and repaired the thatch over a period of 2½ days.
