Contact QtyLab

QtyLab is a free DIY quantity-planning site. If something looks wrong in a calculator, you want a new tool, or you have a privacy question, email admin@qtylab.com. That address is monitored for site support — not a phone line or live chat.

What to write about

• Calculator ideas or feature requests (materials, units, or project types we should add)
• Errors, confusing labels, or results that do not match a real-world takeoff
• Broken links, missing guides, or content corrections
• Privacy, cookies, analytics, or affiliate disclosure questions

What to include so we can help faster

Send the page URL (for example /concrete/ or a guide under Guides), the inputs you used, the result you saw, and what you expected. Screenshots help for layout bugs. Do not send passwords or payment details — QtyLab does not process payments on-site.

What to expect

We read every message. Response time varies with volume; clear details get clearer answers. For how we handle data, cookies, analytics, and affiliate links, see the Privacy Policy. To learn who runs the site and how the calculators work, visit About QtyLab.
