Flooring Verification Checklist

Essential Checklist+

Complete these critical checks before approving the work or proceeding to the next construction stage.

✓11 Inspection Points
✓5 Verification Categories
✓Room & Subfloor Measurement+
  • Room length and width (or a known floor area) were measured on site, not taken from a floor plan alone, since as-built dimensions commonly differ from drawings by several centimetres.
  • Subfloor was checked for flatness (commonly within 3 mm over a 2 m straightedge, product-dependent) — floating floors telegraph subfloor irregularities and can develop joint-lift over time if this is skipped.
  • Subfloor moisture content was checked with a moisture meter, especially over concrete, before committing to a vapor barrier decision.
✓Layout Pattern and Wastage+
  • Layout Pattern matches what's actually planned for installation — Straight, 1/3 Stagger, Diagonal, or Herringbone — since this changes the suggested wastage significantly.
  • Wastage allowance reflects the room's actual conditions (higher for a small room, an angled pattern, or a room with many corners) rather than defaulting to the minimum every time.
  • The final quantity including wastage — not the pre-wastage raw total — is what was used to place the flooring order.
✓Underlayment and Vapor Barrier+
  • The decision on whether underlayment is needed was made based on the specific flooring product's installation instructions, not assumed either way.
  • If a vapor barrier is required (commonly over concrete, especially ground-level or below-grade slabs), it was budgeted as its own separate line item, not assumed to be built into the underlayment.
✓Flooring Type and Specification+
  • Flooring Type (Laminate or SPC/Vinyl) matches the room's actual use — SPC/vinyl for bathrooms, kitchens, and basements where moisture exposure is higher, laminate acceptable elsewhere.
✓Purchase and Final Checks+
  • Box coverage was confirmed against the actual product label, and Multiple Rooms' Same Flooring Product setting matches whether every room really does share one flooring order.
  • An 8-12 mm expansion gap at every wall and fixed vertical surface was planned for, since floating floors expand and contract with temperature and humidity.

✓Room & Subfloor Measurement+
  • Room length and width (or a known floor area) were measured on site, not taken from a floor plan alone, since as-built dimensions commonly differ from drawings by several centimetres.
  • Fixed obstacles (kitchen island, built-in cabinet, hearth) whose footprint won't be floored were measured and entered as Fixed Obstacle Area, rather than estimated or skipped.
  • Subfloor was checked for flatness (commonly within 3 mm over a 2 m straightedge, product-dependent) — floating floors telegraph subfloor irregularities and can develop joint-lift over time if this is skipped.
  • Subfloor moisture content was checked with a moisture meter, especially over concrete, before committing to a vapor barrier decision.
  • For an irregular or multi-section room, Multiple Rooms mode was used to calculate each rectangular section separately rather than forcing one non-rectangular room into a single calculation.
✓Layout Pattern and Wastage+
  • Layout Pattern matches what's actually planned for installation — Straight, 1/3 Stagger, Diagonal, or Herringbone — since this changes the suggested wastage significantly.
  • Wastage allowance reflects the room's actual conditions (higher for a small room, an angled pattern, or a room with many corners) rather than defaulting to the minimum every time.
  • End joints are planned to be staggered by at least 20-30 cm between adjacent rows (for Straight/Stagger layouts) so joint lines don't align into a visible seam.
  • The final quantity including wastage — not the pre-wastage raw total — is what was used to place the flooring order.
✓Underlayment and Vapor Barrier+
  • The decision on whether underlayment is needed was made based on the specific flooring product's installation instructions, not assumed either way.
  • If a vapor barrier is required (commonly over concrete, especially ground-level or below-grade slabs), it was budgeted as its own separate line item, not assumed to be built into the underlayment.
  • Underlayment and vapor barrier seams were planned to be taped, not just butted together, since a gap defeats the point of either layer.
  • Underlayment/vapor barrier coverage and price reflect the actual product's roll or sheet size, not a rough guess.
✓Flooring Type and Specification+
  • Flooring Type (Laminate or SPC/Vinyl) matches the room's actual use — SPC/vinyl for bathrooms, kitchens, and basements where moisture exposure is higher, laminate acceptable elsewhere.
  • Plank size and finish were confirmed against the actual product ordered, since this affects the visualization and the expansion-gap requirement at the walls.
  • AC (abrasion class) rating for laminate, or wear-layer thickness for SPC/vinyl, matches the room's expected foot traffic.
  • All boxes for the same room (or the whole job, if using the same product) were ordered from the same production batch/dye lot, since batch-to-batch shade variation can be visible across a floor.
✓Purchase and Final Checks+
  • Box coverage was confirmed against the actual product label, and Multiple Rooms' Same Flooring Product setting matches whether every room really does share one flooring order.
  • An 8-12 mm expansion gap at every wall and fixed vertical surface was planned for, since floating floors expand and contract with temperature and humidity.
  • Planks were allowed to acclimate in the room (commonly 48 hours, product-dependent) before installation, especially for a significant temperature/humidity difference from the storage area.
  • Obstacles, fixed cabinets, and doorway transitions were physically re-checked against the obstacle area entered into the calculator immediately before the order was placed.
