Editorial Policy

1. Editorial Standards

At HomeProject.tools, we strive to produce clear, accurate, and completely objective planning resources. Our calculators and guides are created to serve our users directly. We do not accept sponsored content or biased partnerships that promote specific commercial brand materials over standard architectural sizing standards.

2. Content Creation Process

Our guides and informational resources are authored by professional copywriters with proven experience in construction trades, residential development, or engineering. All written articles undergo multi-step drafting, copywriting, and formatting checks to ensure information is digestible, clear, and actionable.

3. Formula Validation Process

Before coding any calculator, we research standard building manuals and manufacturer specs. All mathematical equations (such as area, volume, and material multipliers) are double-checked by a secondary reviewer against verified academic, code-compliance (IRC/IBC), or general trade standards to ensure they are theoretically sound.

4. Calculator Testing Process

Every calculator is subjected to testing before deployment, which includes:

• Imperial and Metric Parity: Testing math conversions across feet, inches, meters, yards, and kilograms.
• Validation Boundaries: Ensuring form inputs handle high and low limits, displaying clear error messages rather than yielding broken calculations.
• UI Render Checks: Verifying responsiveness across mobile viewports and desktop resolutions.

5. Content Review Process

We review the entire calculator catalog and guide database at least once a year. This ensures formulas align with the latest building codes, local supplier dimensions, and packaging updates. Any out-of-date guides are revised to preserve platform reliability.

6. Update Policy

When building code regulations change or calculators are optimized, revisions are applied immediately. Statically generated pages are rebuilt and redeployed to push modifications live, keeping users up-to-date.

7. Error Correction Policy

We correct mathematical or typographic errors immediately upon detection or notification. If a user reports an anomaly, we validate the claim against our formula references, update the codebase, and document the fix within our version history.

8. Sources & References

Our calculations and guide advice reference highly authoritative sources, including:

• International Code Council (ICC) — International Residential Code standards.
• National Roofing Contractors Association (NRCA) — Roofing waste calculations.
• Tile Council of North America (TCNA) — Grout and tile spacer dimensions.
• American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) — Regional heat load calculations.

9. User Feedback Process

User feedback is our most valuable source of improvement. If you have comments, suggestions, or notice a math discrepancy, please fill out the form on our contact page. We prioritize reviewing user tickets within 48 hours.
