Estimate materials like a pro

The most common renovation mistake is guessing quantities — you either run short mid-job or waste money on returns. Renoculate uses the same area-and-waste math contractors rely on, so your estimate lands close to what you'll actually use.

Every result includes a sensible waste allowance (cuts, spills, breakage) and rounds up to whole units you can actually buy. Estimates are a starting point; always confirm against your product's coverage label.
