The most rot-resistant wood retaining wall would be made of
Explanation The answer is PRESERVED WOOD FOUNDATION PRESSURE TREATING. Preserved wood foundation pressure treating is quite effective and would form the most rot-resistant wood retaining wall. If we had our choice, we wouldn't use wood for retaining walls, but wood is popular because it fits into landscaping and is relatively inexpensive.

The answer is EXCESS SOIL MOISTURE ADJACENT TO THE HOUSE. Having trees or shrubs too close to a house doesn't usually create excess moisture in the soil adjacent to the house.
Which of the following homes is most likely to have concealed damage behind the EIFS? A home
The answer is EXPOSED TO STRONG WINDS. A house exposed to strong winds will be susceptible to moisture penetration by wind driven rain. The other items in this question are either dry climates or details that tend to protect against damage.

The answer is SAG. Scanning along a porch at floor level is a good way to check for sag in the porch.
Landings at the top of steps should be
The answer is SHOULD BE LARGE ENOUGH TO OPEN THE DOOR WITHOUT HAVING THE STEP DOWN OFF THE LANDING. Good building practice dictates that someone coming up the steps should not be knocked down by someone opening the door from inside.

The answer is SIX INCHES BELOW THE WINDOW. A drain that is six inches below the window is a good arrangement in a window well.
A common recommendation for lot grading is
The answer is SIX INCHES FOR THE FIRST TEN FEET. For lot grading, a slope of six inches for the first ten feet is a common recommendation. Home inspectors usually do not measure these slopes. As a rough guide, you should look for a slope that is visible to the eye.
Draping of concrete garage floors is usually caused by
The answer is SLAB SETTLEMENT AT PERIMETER. Draping of concrete floors in garages usually is caused by settlement of the slab around the perimeter, which in turn is caused by settlement of the backfill along the foundations.
You are looking at a two-story masonry building. You notice large metal plates on the front and back walls of the home about every four feet across the walls, at approximately the second-story floor level. These are
The answer is STABILIZING A BOWED WALL. These plates are typically holding a bowed wall together. They usually attached to cables or rods that go right through the building.
A properly operating "auto-reverse" feature should
The answer is STOP AND REVERSE IF AN OBSTRUCTION IS SENSED ON THE WAY DOWN. The auto-reverse mechanism on a garage door opener should cause the door to stop and reverse if an obstruction is sensed on the way down.
What would you do if you saw metal ductwork from a forced-air heating system for the house passing through a garage?
The answer is SUGGEST THAT IT BE INSULATED TO THE LEVEL REQUIRED IN THE AREA. Metal ductwork from a forced-air heating system passing through a garage should be insulated.
Why is carpeting on wood porches considered to be a problem?
