readings at the stain, compared to the
base line can indicate elevated moisture
near the stain area.
Your moisture meter may respond to
metal in a wall as it would to an increase
in moisture content. To determine if the
elevated readings are caused by metal,
scan in the direction of a straight line,
horizontally, then vertically away from
the point where you obtained elevated
readings. Notice if the meter is responding
to what may be a piece of metal or wood
stud rather than an area of elevated
moisture. By observing the shapes of the
elevated reading area you may obtain
clues as to whether the readings are from
moisture or from metal such as a pipe or
copper wire.
Be aware of hidden metal objects that are
used in construction. Common examples
