Question 1

An inspector observes white crystalline deposits (efflorescence) on interior basement masonry walls. What does this PRIMARILY indicate?

Accepted Answer

Water is moving through the masonry wall and depositing dissolved salts

Answer

Efflorescence is caused by water migrating through masonry, dissolving soluble salts, and depositing them on the surface as the water evaporates, indicating active or past moisture intrusion.

Question 2

Which type of insulation poses the GREATEST health risk during installation if not properly contained, and requires special handling precautions?

Accepted Answer

Vermiculite insulation (pre-1990 Zonolite brand)

Answer

Vermiculite insulation, particularly Zonolite brand mined before 1990, is often contaminated with asbestos and should be left undisturbed; any disturbance requires professional asbestos abatement.

Question 3

A home inspector finds interior window sills with peeling paint and soft, decayed wood. What is the MOST likely cause?

Accepted Answer

Condensation from interior humidity collecting on the cold sill surface

Answer

Window sills frequently experience condensation when warm interior air contacts the cold glass and sill surface; persistent moisture causes paint failure and eventually wood decay.

Question 4

What is the ASHI Standards of Practice requirement regarding inspection of insulation in finished walls?

Accepted Answer

Inspectors are not required to inspect insulation in finished walls

Answer

ASHI Standards of Practice do not require inspectors to inspect insulation in finished walls since it is concealed; inspectors are only required to report on readily accessible insulation.

Question 5

An inspector finds stair risers that are inconsistent in height, with some varying by more than 3/8 inch from others. What is the PRIMARY safety concern?

Accepted Answer

Trip hazard due to inconsistent step heights disrupting a person's gait

Answer

Inconsistent riser heights are a significant trip hazard because people develop a walking rhythm on stairs; unexpected height changes cause stumbling and falls.
