Flooring photos from subfloor to final walkthrough
Flooring failures are almost never the flooring. They're the subfloor, the moisture, or the conditions the material sat in before it went down — and all three are invisible once the floor is installed. Manufacturers know this, which is why a warranty claim starts with questions about substrate and readings that most crews cannot answer.

What flooring crews document
The shots worth taking, and why each one matters later.
Subfloor condition
The bare substrate photographed across the whole area, including any cracks, deflection or previous adhesive.
Moisture and RH readings
Meter or RH probe in frame with the reading legible, per area, dated — the first thing a manufacturer asks for.
Flatness and prep
High and low spots identified, and the grinding or leveling done to correct them.
Material on delivery
Cartons, lot numbers and any shipping damage photographed on arrival, plus where it acclimated.
Underlayment and layout
Underlayment coverage, seams and starting layout before the field goes down.
Transitions and finish
Thresholds, reducers and edges at completion, where installation quality is actually judged.
The arguments this record settles
Every one of these comes down to whether a dated photo exists.
- Cupping shows up and your dated readings show the slab was within spec at install.
- A manufacturer claim needs lot numbers you photographed instead of a carton long since thrown out.
- Damage is blamed on the installer when the delivery photos show it arrived that way.
- Someone claims the subfloor was never prepped and the grinding is photographed.
A day on a flooring job, on the record
The same two artefacts every project builds up: what happened today, and what still needs fixing.
A daily log from this trade
Subfloor prepped, readings within spec
Ground down two high spots at the kitchen transition, filled the low area by the slider. RH probe at 72 percent in the main area, 74 by the exterior wall — both photographed and within the manufacturer range. Material delivered Tuesday, acclimating in the living room, lot numbers photographed. Layout starts tomorrow from the hall.
Crew members post updates with photos straight from the field, so the entry lands on the day the work happened.
Punch items that come up
- Install reducer at the kitchen to tile transition
- Replace two planks with visible mill defect near the window
- Re-shoe baseboard in the hall after final row
Each item carries before and after photos, so completion is visible without another walkthrough.
