After exploring the exterior of the home, the home inspector should examine the foundation of the residence. Since the foundation supports the weight of the entire structure; this area of the building must be constructed under strict adherence to all applicable building codes and undergo rigorous safety inspections. Foundation problems can cause plumbing leaks, squeaky and uneven floors, sticking doors and windows, and cracked walls. This course will identify the factors that affect foundation design and the types of materials and components used in foundations. In addition, this course will specify inspection items for foundation problems and indicate methods used in foundation repair and retrofitting.
