Wood Destroying Organism (WDO) Home Inspection Practice Exam

True or False: Door frames and jambs are permitted to extend through concrete floors.

1. True

2. False

3. Only if properly sealed

4. Only in basements

The correct answer is: False

The premise of the question revolves around the structural integrity and moisture control required in building construction, particularly focusing on door frames and jambs in conjunction with concrete floors. The correct answer indicates that door frames and jambs are not permitted to extend through concrete floors, which is aligned with best practices in building design. When door frames penetrate concrete floors, it poses several potential issues. One primary concern is moisture intrusion. Concrete can retain moisture, and if door frames are allowed to extend through it without appropriate sealing, the frames could absorb this moisture. Over time, this may lead to wood rot, mold growth, and can compromise the overall structural integrity of both the door frame and the surrounding area. Proper sealing is critical in preventing moisture problems, but the initial design should ideally avoid such situations altogether. Additionally, allowing door frames to extend through concrete can hinder the structural support that the concrete offers, potentially leading to issues such as cracking or fracturing of the concrete around the door opening. While sealing may mitigate some moisture issues, the general best practice is to avoid such configurations entirely. This understanding is crucial for anyone involved in home inspection, as it informs the necessity of adherence to building codes and best practices related to moisture management and structural integrity in homes.
