Performance Standard: 1/8 inch in 16 inches, or 1/4 inch in 24 inches, are unacceptable.
Corrective Measure: The remodeler will install additional nails in siding to meet acceptable nailing schedules and will replace any siding that has bows exceeding the performance standard.
Discussion: Some waviness in siding is to be expected because of bows in studs. However, proper nailing of siding will straighten most bows.
