In its final report, the Barrett Commission determined that BC's Crisis was the result of a total system failure, and it identified several key contributors, not the least of which were imprudent building design and a reliance on uncertified and inexperienced contractors. In fact, intersections involving windows, doors and decks were identified as the most frequent locations for water ingress. Stucco installed by a certified contractor is specifically designed to prevent the type of leakage and building rot that typified the Leaky Condo Crisis. For a building envelope to be effective in wet weather, it must be able to breath, allowing water that does permeate the surface to escape through specifically designed drainage channels, one of the principle features of a traditional stucco system. Stucco performs well in all weather and climatic conditions. It is, in fact, hydraulic cement, which means it hardens or cures with each successive exposure to water.
