Frequently Asked Questions
How much extra flooring should I buy?
Always buy 10% extra for standard straight-lay installation. Buy 15% extra for diagonal installation or complex patterns. Buy 20% extra for herringbone or intricate designs. Buying extra is cheap insurance — matching flooring from different batches can vary in colour.
How do I calculate flooring needed?
Multiply room length × width to get square footage. Add waste percentage. Divide by the square footage per box to get number of boxes. Always round up to the nearest whole box.
What is the most durable flooring?
Hardwood: 25-100 years with refinishing. Porcelain tile: 50+ years. Luxury vinyl plank (LVP): 15-25 years. Laminate: 15-25 years. Carpet: 5-15 years. For high-traffic areas, porcelain tile or hardwood are the most durable options.
