InterNACHI Exterior and Grounds Inspection 3

Question 1

Which type of retaining wall deficiency is considered a safety hazard during an exterior inspection?

Accepted Answer

Leaning or bulging wall with no weep holes

Answer

A leaning or bulging retaining wall without weep holes indicates hydrostatic pressure buildup that can cause catastrophic wall failure.

Question 2

What does the presence of stair-step cracking in brick veneer most commonly indicate?

Accepted Answer

Differential settlement of the foundation

Answer

Stair-step cracks follow mortar joints and typically indicate differential foundation settlement, which can be a significant structural concern.

Question 3

An inspector sees that a downspout terminates at the foundation wall with no extension. What is the recommended correction?

Accepted Answer

Add a splash block or extension to direct water at least 6 feet from the foundation

Answer

Downspouts should discharge water well away from the foundation to prevent soil saturation and basement water intrusion.

Question 4

What is the InterNACHI-recommended minimum clearance between wood framing or siding and the soil grade?

Accepted Answer

6 inches

Answer

InterNACHI standards recommend at least 6 inches of clearance between wood elements and soil to reduce rot and termite risk.

Question 5

When inspecting vinyl siding, which defect is most likely to allow bulk water entry?

Accepted Answer

Missing J-channel or unsealed penetrations at openings

Answer

Missing J-channel or unsealed gaps around windows, doors, and penetrations leave openings where bulk water can enter behind the siding.
