Describe when the stain changes
A window stain that grows after rain needs a different source review from one that follows indoor condensation. Note which side of the opening becomes wet and whether the sill or adjacent wall changes first. Photos taken at different times can help explain the pattern. Do not assume a new bead of caulk will correct every possible path for water.
Plan cleanup after the source is understood
A qualified building professional may need to investigate flashing, sealants, or the wall assembly. Interior cleanup should address affected materials rather than simply cover the stain. Ask how the source repair will be coordinated before new finishes go back. Share the repair findings with the remediation team so both scopes address the same area.
