Expert Insights
Smart analysis for your Flooring project
Pattern Waste Calculator
Straight lay: 10% waste. Diagonal: 15%. Herringbone: 20%. AI selects the right waste factor for your pattern — not a flat percentage.
Subfloor Readiness Check
80% of flooring failures trace to subfloor issues. AI flags moisture, leveling, and prep requirements based on your material choice.
Material Lifespan Comparison
Hardwood: 100+ years (refinishable). Laminate: 15-25 years. Vinyl plank: 20-30 years. AI calculates cost-per-year for each option.
Calculation Formula
Total = Area x (1 + Waste%)
Boxes = Total / ~20 sq ft per box
