A CMI observes diagonal cracks at the corners of window openings. What is the most likely cause?
Answer: Differential foundation settlement causing structural movement
Diagonal stair-step or diagonal cracks radiating from window corners are classic indicators of differential settlement placing stress on the wall assembly.
When documenting a defect in a CMI-level report, which approach provides the strongest actionable guidance?
Answer: Describe the defect, its location, likely cause, and recommend a qualified contractor for evaluation or repair
A complete defect entry includes description, location, probable cause, and a specific referral recommendation, which fully informs the client and limits inspector liability.
What does efflorescence on a masonry foundation wall primarily indicate?
Answer: Water has migrated through the masonry, depositing mineral salts on the surface
Efflorescence is the white crystalline deposit left when water carrying dissolved salts evaporates from the masonry surface, indicating ongoing or past water intrusion.
A CMI finds that floor joists have been notched at mid-span. Why is this a significant structural concern?
Answer: Mid-span notching cuts through the tension zone of the joist, severely reducing load-bearing capacity
The bottom of a joist at mid-span is the highest-stress tension zone; notching there can reduce load capacity by 50% or more and is prohibited by most building codes.
Which condition in an attic most directly indicates a chronic roof leak rather than a one-time event?
Answer: Stained and darkened wood with active microbial growth along a consistent pattern
Chronic leaks leave repeated stain patterns, biological growth from sustained moisture, and often deteriorated wood, distinguishing them from isolated single-event wetting.
What is the most accurate way to assess whether a visible crack in a concrete slab is active or dormant?
Answer: Apply tell-tale marks or witness points across the crack and re-inspect over time
Witness marks or tell-tales placed across a crack reveal whether movement is ongoing by showing displacement or cracking of the mark, confirming active versus dormant status.
