The easiest way to check walls for plumb is
to put a spirit level on the wall
. If the bubble is not in the centre of the vial, you'll need to find out how far out of plumb the wall is by moving either the top or bottom of the level away from the wall until the bubble finds centre.
How do you measure if a wall is plumb?

rotate the level 180 degrees
, edge to edge, keeping the same end facing up. The bubble should be in the same spot. If not, your plumb vial is off.
What instruments are used to determine if a wall is plumb?

How do you use the plumb rule?
- Measure two to three few inches away from the top of the wall and make a mark.
- Set a nail in the mark.
- Hang the plumb bob on the nail, letting gravity draw a vertical reference line for you.
- When the plumb bob is done oscillating, measure the distance from the wall.
How much wall can plumb out?
The Residential Construction Performance Guidelines suggest a maximum out of plumb of
3/8′′ in 32′′ vertically
