1. Concrete cancer: This is the rusting of steel reinforcement inside concrete. As it rusts it expands and creates major structural problems due to ‘spalling’, where the concrete moves away from itself. This can allow water and moisture to seep in and cause further damage. “It can be very, very dangerous if the cancer is left too long,” Tanton says.
2. Termite damage: People have heard the horror stories; even just exploring a property affected by termites to determine the extent of the damage can be expensive.
3. Damp: It can come up from the ground, down from the roof, or from within the walls from leaky plumbing.
5. Water damage: This arises from drainage and plumbing issues.
7. Roofing: Not many people look at their roof on a regular basis, Tanton says, so a lot of damage can be uncovered in a building report.
10. Electrical wiring: Several homes have electrical problems that aren’t visible on the surface.
12. Frame damage: Regardless of whether frames are made of timber or metal, their condition can deteriorate and cause major structural issues.
