Contact MaterialCalcs

Questions, corrections, or feedback on a calculator or guide? Email us — a real person reads every message, and we usually reply within a few days.

Get in touch

The best way to reach us is by email at [email protected]. There’s no form to fill out and no account to create — just send a note and we’ll take it from there. We read everything that comes in and typically respond within a few days.

When to reach out

We especially want to hear from you when something on the site looks off: a calculator result that doesn’t add up, a broken or outdated source link, store pricing that no longer matches what we list, or a typo in one of our guides. General feedback is just as welcome — what helped, what was confusing, or a material, calculator, or topic you’d like us to cover next. Partnership and press inquiries reach us at the same address.

Before you email

If you’re in the middle of a project, you might find the answer faster in our mulch guides or straight from the mulch calculator. For how we handle your data, see our Privacy Policy; to learn how we verify every number, visit the About page. When you report a correction, a link to the exact page — and the number or sentence in question — helps us find it and fix it quickly.
