When drywall has to come out

Quick answer

Why restorers cut a strip of wall even when the paint looks fine, and how that decision changes cost.

Paper-faced drywall wicks water above the visible stain. If the cavity stays wet, mold and swollen studs follow. A two-foot flood cut can look aggressive on day one and cheap compared with a redo on day ten.

Ask what moisture readings they need before they close the wall. Ask whether insulation is wet. Those two answers explain most of the labor line.
