The cost of a bad scan is not the scan. It is the second drive out. Two minutes of checking before you pull away catches nearly all of it.
Walk the list
- Room count — does the model have as many rooms as the house? A missed closet or powder room is the most common miss.
- Every door opened — closets, pantry, mechanical room. A closed door scanned as a wall is a room that does not exist.
- Floor stack — on a multi-level house, spin the model and confirm the upper floor sits at the right height above the lower one.
- Walls that should be straight — a bowed or doubled wall usually means a mirror, glass, or a rushed sweep.
- Openings present — windows and doors showing up in the rooms you care about pricing.
- The numbers you came for — the specific quantity this bid depends on. Pull it up and look at it. If the kitchen is the job, read the kitchen's wall area now.
Spot-check one dimension with a tape
Pick the longest clean wall in the main room and measure it. If the scan agrees within an inch or so, the rest of the capture is almost certainly fine. If it is off by a foot, something went wrong and you want to know now.
Notes before the drive
Anything you flagged mid-scan — a wall behind a built-in, a niche, an access panel — gets captured as a voice note while you are still standing in the room. Memory does not survive the drive back.
Make it a habit, not a decision
The crews who never make rescan trips are not better scanners. They just run the same six-item check every time, before the truck starts.
The scan you check on site is the scan you only do once.
