Last updated: 7/22/2026

1. Agreement to Terms

By accessing the website at BuilderCal.com, you are agreeing to be bound by these Terms of Service and all applicable laws and regulations. If you do not agree with any of these terms, you are prohibited from using or accessing this site. The materials contained in this website are protected by applicable copyright and trademark law.

2. Use License

BuilderCal grants you a personal, non-exclusive, non-transferable, revocable license to access and use the calculators and information provided on the website for both personal and professional commercial estimating purposes. However, under this license you may not:

  • Modify, copy, or reverse-engineer the calculator algorithms or source code;
  • Use automated scripts, bots, or scrapers to extract data or calculator logic from the website;
  • Attempt to decompile or extract the React and Astro hydration scripts;
  • Remove any copyright or other proprietary notations from the materials; or
  • Transfer the materials to another person or "mirror" the materials on any other server.

This license shall automatically terminate if you violate any of these restrictions and may be terminated by BuilderCal at any time.

3. Disclaimer of Accuracy (Important)

The calculators, diagrams, and formulas on BuilderCal's website are provided on an 'as is' basis. While we aim to calculate consistently from the values and assumptions entered, BuilderCal is an estimation tool, not a substitute for professional engineering or architectural advice.

Construction materials are subject to environmental factors, subgrade settling, spillage, and mixing variations. BuilderCal makes no warranties, expressed or implied, regarding the exactness of the final material yield. Use a project-appropriate waste allowance and confirm important purchasing or construction decisions with qualified local professionals and suppliers.

4. Limitations of Liability

In no event shall BuilderCal, its founders, or its suppliers be liable for any damages arising out of the use or inability to use the materials on the website. This includes, without limitation:

  • Financial losses from ordering incorrect amounts of concrete, gravel, or other materials;
  • Structural failures resulting from under-ordering materials;
  • Project delays or labor costs associated with material shortages;
  • Loss of data or profit, or business interruption.

Because some jurisdictions do not allow limitations on implied warranties, or limitations of liability for consequential or incidental damages, these limitations may not apply to you.

5. Revisions and Errata

The materials appearing on BuilderCal's website could include technical, typographical, or mathematical errors. BuilderCal does not warrant that any of the materials on its website are accurate, complete, or current. We may make changes to the calculators or formulas at any time without notice, although we are not strictly obligated to update the materials.

6. External Links

BuilderCal may contain links to third-party websites or services that are not owned or controlled by us. We have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party websites. The inclusion of any link does not imply endorsement by BuilderCal of the site.

7. Governing Law

These terms and conditions are governed by and construed in accordance with standard international internet laws, and you irrevocably submit to the exclusive jurisdiction of the courts in your State or location.
