This is a problem with an old chimney - the house was built in 1919 and the
chimney is probably that old - don't know for sure.

The mortar has weathered thru in places. What's the best material to use
for patching it up?



Chimney guy coated the mortar around ceramic pipes on my chimney with a
mortar mix which I think contained acrylic binder. As other poster
points out, bricks may need to be repointed. This senior no longer
climbs on his roof but if I were younger could have DIY.
