Last updated: July 19, 2026
Email is the fastest path. No contact form and no account. Write about a formula bug, a confusing page, or a privacy question — we read every message.
Include the page URL and, for calculator issues, the inputs you used so we can reproduce the ticket.
Good reasons to write
- Wrong bag yield, volume formula, paint coverage, or pitch math
- Copy that overpromises accuracy or buries the estimate disclaimer
- Broken link, layout issue, or accessibility problem
- Privacy question about analytics, ads, or localStorage theme
What we cannot help with
We cannot design foundations, approve mix designs, price labor, mediate contractor disputes, or promise a truck will deliver the exact yards on a rainy Tuesday. For structural or bid questions, talk to a licensed professional or your supplier.
Before you write
Formulas: methodology. Privacy: privacy. Terms: terms. Many “is this a bug?” questions are answered there.
Estimate only — not a contractor bid. Confirm bag yields, coverage rates, and truck quotes with your supplier before you order.
