In general, a building inspection lasts 2 to 3 hours. After introducing himself to the vendor and other stakeholders, the building inspector observes the ground and drainage conditions around the building. He carefully scrutinizes the foundation and checks the condition of the exterior components (cladding / fenestration / perron / gallery, etc.). When conditions permit, the building inspector climbs onto the roof to complete the building inspection of the exterior components. Inside, the building inspector places a lot of importance on the building inspection of the basement components (foundation / insulation / structure / mechanics) and ensures that no problem of water infiltration, humidity excessive or apparent mold is present. Subsequently, each piece of the building is checked and the building inspection ends with observation of the attic components.
