Contact BlacktopCalc

Found a bug, have a suggestion, or spotted a number that doesn't look right? Send us a message. We're a small team and we genuinely read and respond to everything.

Send a message

Use the form below. We typically reply within 1–2 business days. For bug reports, the more detail the better.

🐛 Reporting a bug?

The more detail the better. Tell us: which calculator you were using, what values you entered, what result you got, and what you expected. A screenshot is worth a thousand words.

💡 Have a feature idea?

We genuinely build based on what real users ask for. Already on the roadmap: hot-in-place recycling calculator, chip seal estimator, and a concrete calculator for comparison. Tell us what you need most.

📐 Spotted a data error?

If you're an engineer, contractor, or DOT professional and something looks wrong in our density values, formulas, or benchmarks — please tell us. We take accuracy seriously and we investigate every correction report.

⏱ Response time

We aim to reply within 1–2 business days. Bug fixes and data corrections are prioritised. We are a small team — not a help desk — so responses are personal, not templated.
