See the formulas, assumptions and limitations behind PrepMyBuild project estimates and quote checks.
Material quantities come from explicit formulas using the measurements you enter. We do not ask an AI model to invent the arithmetic.
Waste allowances, aggregate density, paint coverage and spacing assumptions are planning inputs. They may not match your specific product or site, so they are shown rather than hidden.
The beta quote checker looks for written scope and common clarification points. It does not judge contractor competence, legal sufficiency, code compliance or price fairness.
PrepMyBuild is best used as a preparation and cross-checking tool before speaking with a supplier or contractor.
