This collection of images is of a church bell tower built in 1928. They started having leaks about 10 years ago, a succession of contractors came along and attempted to "fix" the water intrusion issues. Each fix essentially added to the issues of "leaks".
The biggest problem was that each one created a more semi--conditioned space than the last one. Channel airflow from the conditioned space continued to carry air transported v***r up through the multiple floors of the bell towers, resulting in condensation and subsequent freezing and thawing of ice. This destroyed the mortar and also caused water damage in the floors, ceilings and walls below.
The fix for this project was to remove all "improvements" and return the structure to original construction and air flow management as it was at the time it was built.
