Contact.
No contact form, no ticketing system, no email gate. Every message goes to one inbox and gets sorted by subject line.
Everything routes to [email protected]. Corrections, calculator requests, privacy and terms questions, affiliate and partnership inquiries, accessibility reports, and press.
Prefix the subject line with one of the topics below to speed triage:
- Correction math error, broken source link, outdated code citation, regional pricing that does not match reality
- Calc request a calculator that should exist and does not, with a concrete field scenario
- Privacy GDPR / CCPA / CPRA requests or other data questions
- Terms questions about the terms and disclaimer page
- Disclosure affiliate, sponsorship, or partnership questions
- Accessibility barriers reaching calculator content with assistive technology
- Press media inquiries
Corrections that include the calculator name, the input values used, the output received, the expected output, and a source citation for the expected value ship first. Calc requests with a field scenario (what the project looks like) and the specific math question a calc would answer are second. Everything else is answered as time allows.
MaterialForeman is not a licensed contractor, engineer, architect, or code official. Questions about whether a specific project complies with local code, whether a subgrade is adequate, whether a span is safe, or whether a permit is required will be redirected to a licensed professional in the applicable jurisdiction. See terms and disclaimer for the full scope boundary.
MaterialForeman operates as a solo remote publisher. No walk-in address is published. Legal service, press outreach, and partnership inquiries all route through the inbox above.
Before emailing a correction, the methodology page explains how formulas are derived and the sources index lists every citation across the fourteen calculators. Affiliate mechanics are documented on the affiliate disclosure page.
