" QUOTE Mustapha.I believe the mortar to be just fine; the problem has a number of causes. 1) Water ingress from leaking roof/flashing, hence the renewed roof? and or flashing.2) "Fancy", brickwork as in the orientation of the brick as well as recessing of the same.3) Likely total absence of past tuckpointing leading to water penetration.FYI: Brick is to be considered permanent with the mortor being rather a soft temperary.ALSO -More stone/brick walls have been dispatched by careless tuckpointing than I care to remember.Most tuckpointing/mortor replacement now-a-days is attackedby with the use of power grinders whichafter numerous jobs destroy the brick. Historic properties should always be finessed with hammer and chisel. - BIG MONEY!Regards,J...
