Material Quantity and Cost Guides: Drywall, Tile and Concrete
Every renovation quote starts with a quantity. This hub collects the RenoCalc Hub material-takeoff guides — sheet counts, waste factors and per-square-foot pricing — so you can check a supplier list or a contractor's material line before you pay for it.
- Order materials by takeoff plus a waste factor, never by rounded guesswork.
- Drywall is counted in sheets; tile in square feet plus 10-15% waste.
- Concrete is ordered in cubic yards — depth in inches divided by 324.
