WLFI Defect Analysis & Claims Assessment 3

Question 1

A hardwood floor inspector observes 'crowning' across multiple boards. Which environmental condition is most often responsible?

Accepted Answer

Elevated moisture on the surface or excessive humidity causing top-face swelling

Answer

Crowning occurs when the top face of a board absorbs more moisture than the bottom, causing the center to rise above the edges.

Question 2

During a claim investigation, an inspector detects hollow spots under a glue-down hardwood floor. What tool is most commonly used for this assessment?

Accepted Answer

Sounding hammer or tap test rod

Answer

A sounding hammer or tap test reveals hollow areas by the difference in acoustic resonance between bonded and unbonded sections.

Question 3

A claim involves gray or black staining in an oak floor. The staining is concentrated near exterior walls and under windows. What is the most probable cause?

Accepted Answer

Mold or mildew growth from chronic moisture intrusion at the building envelope

Answer

Gray or black staining concentrated near exterior walls and windows strongly suggests mold from chronic moisture intrusion rather than a chemical or manufacturing issue.

Question 4

What is the inspector's primary responsibility when a claim involves both potential product defects and installation errors?

Accepted Answer

Document all findings objectively and identify the most probable cause for each defect

Answer

An inspector must objectively document all conditions and identify the probable cause of each defect to allow all parties to determine appropriate liability.

Question 5

A laminate floor shows widespread joint peaking (ridge formation at board edges). What installation error most commonly causes this?

Accepted Answer

Insufficient expansion gap causing the floating floor to buckle at joints

Answer

Joint peaking in laminate is almost always caused by insufficient perimeter expansion space, which forces upward displacement at the locking joints.
