Hidden damage is where budgets explode. Repair planning should assume you will find something once you open up.

Before you lock scope, check:

1. Moisture pathways: where water could travel, not just where it shows.
2. Staining patterns: repeated marks usually indicate repeated cause.
3. Softness and deflection: flooring bounce, wall softness, ceiling sag.
4. Odors and corrosion: musty smell, rust, fastener corrosion, efflorescence.
5. Adjacent systems: plumbing above, roof penetrations, exterior joints, drainage.
6. Previous patch signs: mismatched paint, fresh caulk lines, new trim segments.

Technology touch: create a simple phone folder system:

1. One folder per room or area
2. Photos named by date and location
3. A single note that lists measurements, observations, and “questions to answer”
4. Marked-up photos with arrows and short labels

One clean documentation set can save hours of back-and-forth and reduce the chance you approve the wrong scope.
