We're on our 3rd chimney...
....even tho' we try and manoevre as carefully as possible.
So, for this one we've (her idea) tightly tied a piece of string round
the outlet in the roof and attached the other end to the chimney cap -
that keeps coming off. We reckon by the time the gases from the fire
get up there they'll be cool enough not to worry about the heat.
Anyone else use this idea?
