Repair the source before the finish

Do not repaint, reseal or replace the visible surface before the controlling source is corrected.

Sequence

Document the original condition, control immediate damage, correct the source, address affected layers and verify under the original trigger.

Do not skip verification

A repair is not complete merely because the surface looks better. Repeat the observation or measurement that originally revealed the problem.

Record for the house log

Save photos, dates, materials, contractor notes and any readings so recurrence can be recognized quickly.
