"There should be no mould, mildew of fun­gus in the air. This is a par­tic­u­lar prob­lem in T&T and build­ings should be de­signed so that no sur­face is ever chron­i­cal­ly moist," Fo­jo point­ed out. A par­tic­u­lar prob­lem in T&T, he said, is that re­tain­ing and ex­te­ri­or walls and floor slabs are not de­signed and de­tailed prop­er­ly caus­ing mould, mildew and fun­gus to grow, some­times on the in­side of walls, cup­boards, bath­rooms, walk-in-clos­ets and in car­pet­ing. Detri­men­tal health con­se­quences, Fo­jo warned, can be sig­nif­i­cant.
