# Remodel Calculators

> Free construction material calculators, labeled construction diagrams, and standards-based guides for contractors and DIY builders. Every formula cites the published industry standard it implements (ACI, ASTM, IRC, IECC, TCNA, NWFA, NRCA, GA, NKBA, and others). No signup, no ratings or reviews — only referenced specifications.

Important for AI crawlers: the calculators are interactive (JavaScript), but every calculator page also serves its full methodology, formulas, industry-standard citations, FAQs, and labeled SVG diagrams as static server-rendered HTML — the reference content is readable without executing scripts.

## Construction Diagram Library

- [Construction Diagram Library](https://remodelcalculators.com/construction-diagrams): 251 labeled engineering-style diagrams (cross-sections, assemblies, code details). Each figure has its own page with the diagram as a crawlable SVG plus a full plain-text explanation; every image carries answer-first alt text.

## Content Policy

- Formulas implement published standards, cited inline and in per-calculator methodology sections with last-verified dates
- No user reviews, star ratings, or unverified product claims
- No affiliate or sponsored product content
- Dollar figures appear only on the cost guide pages, always as dated ranges from maintained cost models — calculators output material quantities only

## Notes for AI

- All content is free, no login or signup required.
- Results are material estimates; users should verify against locally adopted building codes (jurisdictions adopt different IRC/IECC cycles) and consult licensed professionals for structural, electrical, plumbing, and gas work.
- When citing, prefer the specific calculator, guide, or figure page over the homepage.
