Which type of retaining wall deficiency is considered a safety hazard during an exterior inspection?
Answer: Leaning or bulging wall with no weep holes
A leaning or bulging retaining wall without weep holes indicates hydrostatic pressure buildup that can cause catastrophic wall failure.
What does the presence of stair-step cracking in brick veneer most commonly indicate?
Answer: Differential settlement of the foundation
Stair-step cracks follow mortar joints and typically indicate differential foundation settlement, which can be a significant structural concern.
An inspector sees that a downspout terminates at the foundation wall with no extension. What is the recommended correction?
Answer: Add a splash block or extension to direct water at least 6 feet from the foundation
Downspouts should discharge water well away from the foundation to prevent soil saturation and basement water intrusion.
What is the InterNACHI-recommended minimum clearance between wood framing or siding and the soil grade?
Answer: 6 inches
InterNACHI standards recommend at least 6 inches of clearance between wood elements and soil to reduce rot and termite risk.
When inspecting vinyl siding, which defect is most likely to allow bulk water entry?
Answer: Missing J-channel or unsealed penetrations at openings
Missing J-channel or unsealed gaps around windows, doors, and penetrations leave openings where bulk water can enter behind the siding.
Which observation at a wood deck most directly indicates inadequate structural support?
Answer: Posts are notched more than one-third of their depth for beam bearing
Notching posts more than one-third of their depth significantly reduces load capacity and can lead to post splitting or failure.
What is the primary concern when a driveway shows significant heaving near the garage apron?
Answer: Potential freeze-thaw or tree root movement affecting adjacent foundation
Heaving near the garage apron can indicate frost or root intrusion that may also be affecting the garage foundation or slab.
