I am going to be installing a tall metal wood stove chimney which will be
11 ft. high from the roof. Note that my roof is also at about a 45 degree
slope, so I can't stand on the roof.

Needless to say, there will be no way to clean this chimney from the top
down without a high-lift.

I spoke to a lady who has a similar chimney and she said they had theirs
cleaned from inside the house - bottom up. Unfortunately, she was not home
when it was cleaned, so did not know how they did it.

The wood stove I will be purchasing will not allow cleaning from inside the
wood stove.

So how do you clean a chimney from inside the house?
