Before and after

BEFORE · what the owner typed
Estimate for Louisa Reddy, 4953 Redleigh St, Pineford. I'm Lowell Sato with Sandleigh Floors, 312-555-0150. Going with Tidewrack Oak Plank in Smoked Pewter, box says 23.4 sq ft per box. Sketch notes: living room 14 by 18.5, but there's a hearth 2 by 5 sticking in that we're not covering. Living room is going diagonal so use 15% waste there. Dining room 11 by 12. Hallway 3.5 by 16. Hall closet 2.5 by 6, flooring goes in the closet. Everything else is 10% waste.

What it does

Takes the room measurements from a sketch or field notes and works out the net square footage, the waste added for each room, and how many whole boxes to order. It shows every calculation so the estimator can check it before ordering.

Use it when: Use when a flooring business needs to turn a room sketch or measurements into square footage, a waste factor, and a box or carton order quantity, such as 'how many boxes do I order,' 'figure the waste on this job,' or 'work out quantities from my sketch.'
