Many brick schools from the early 1900s fail modern inspections not because walls are doomed, but because later cement patches trapped moisture. Clay and lime studios are training apprentices to reverse that damage with softer mortars.
Workshops begin with brick tasting — a tongue-in-cheek term for reading porosity — then move to scaffolding practice on unused wings. Districts save demolition budgets and keep neighborhood landmarks in service.
Insurance underwriters were skeptical until moisture sensors showed drying curves after proper repointing. Now a few policies discount premiums when certified crews handle the joints.
Students notice the difference too: classrooms stay warmer when wind no longer whistles through failed mortar beds.
