The article discusses possible defects of exterior walls of buildings that can occur in a multilayer brick masonry. The article is based on the inspection materials of the school building located in Bronnitsy, Moscow Region. The reasons of brick masonry defects are considered and analyzed. An external wall strength calculation of the stairwell of the building is given, confirming the reasons for the formation of defects in the masonry. The static calculation results of the exterior wall of the building stairwell revealed the presence of tensile forces in the zone of window sill of the lower window opening of the exterior wall of the building. The calculations of masonry tensile showed that load bearing capacity of the masonry in window sill zone is not provided. Thus, the calculation is justified for cracks in the window sill area of the calculated wall. The appearance of hairline cracks on the outer face of a decorative protective layer multi-layer masonry is due to the thermal deformations, the manifestation of which is enhanced by the presence of the layer of effective insulation located behind the layer of masonry and embarrassing action of rigid ties on the development of thermal deformations.
