CHI Property Maintenance & Operations 2 — Questions and Answers
Question 1: What is the minimum recommended clearance between combustible materials and a masonry fireplace opening?
- 2 inches on all sides
- 6 inches on all sides (Correct answer)
- 12 inches on all sides
- No clearance required if mortar is intact
Correct answer: 6 inches on all sides
Combustible materials must be kept at least 6 inches from fireplace openings to prevent ignition from radiant heat.
Question 2: During a home inspection, you notice efflorescence on a basement wall. This MOST likely indicates:
- Structural wall failure is imminent
- Water is migrating through the masonry (Correct answer)
- The wall was painted with the wrong primer
- Normal concrete curing process
Correct answer: Water is migrating through the masonry
Efflorescence is the white salt deposit left when water passes through masonry and evaporates, indicating moisture intrusion.
Question 3: What slope is generally recommended for site grading immediately adjacent to a foundation to direct water away from the structure?
- 1 inch per 10 feet
- 6 inches over the first 10 feet (Correct answer)
- 2 inches per foot
- A flat grade is acceptable
Correct answer: 6 inches over the first 10 feet
The standard recommendation is a 6-inch drop over the first 10 feet away from the foundation to ensure positive drainage.
Question 4: A homeowner complains of condensation on interior window surfaces during winter. The MOST likely cause is:
- Faulty window installation causing air leaks
- Excess indoor humidity combined with cold glass surfaces (Correct answer)
- Broken insulated glass unit seals
- Negative air pressure from the HVAC system
Correct answer: Excess indoor humidity combined with cold glass surfaces
Warm, humid indoor air contacts cold glass surfaces and reaches the dew point, causing condensation on the interior side.
Question 5: Which component of a gas water heater is designed to prevent excessive temperature and pressure buildup?
- Anode rod
- Dip tube
- Temperature and pressure relief (TPR) valve (Correct answer)
- Expansion tank
Correct answer: Temperature and pressure relief (TPR) valve
The TPR valve is a safety device that opens to release water if temperature exceeds 210°F or pressure exceeds 150 psi.
Question 6: When inspecting a wood deck, which condition would be of GREATEST structural concern?
- Surface weathering and graying of the wood
- Ledger board fastened with incorrect nails (Correct answer)
- Minor checking (surface cracks) along the grain
- Paint peeling on deck railings
Correct answer: Ledger board fastened with incorrect nails
The ledger board connection to the house is the most critical deck attachment point, and improper fasteners can cause catastrophic deck collapse.
Question 7: What is the purpose of a weep hole in a brick veneer wall?
- To allow inspection of the wall cavity
- To drain water that accumulates behind the veneer (Correct answer)
- To provide ventilation for insulation drying
- To relieve thermal expansion pressure
Correct answer: To drain water that accumulates behind the veneer
Weep holes allow water that penetrates the brick veneer to drain out of the wall cavity rather than accumulating and causing damage.
