Editorial & Corrections Policy
Effective Date: November 2026 • Last Reviewed: November 2026
1. Editorial Mission & Purpose
At Shiplap Calculator, our mission is to provide DIY homeowners, remodeling contractors, and architectural woodworkers with mathematically rigorous, verified material estimation tools. Unlike generic calculators that multiply raw room area by nominal lumber sizes, our engines incorporate physical joint geometry—including rabbet overlaps, tongue-and-groove profiles, and nickel-gap reveals—to protect builders from unexpected project shortages.
2. Mathematical Auditing & Testing Standards
All calculation algorithms published on our tools undergo a multi-step auditing process:
- Physical Caliper Shelf Stock Audits: We periodically measure actual lumber dimensions from major national retailers (Home Depot, Lowe's, 84 Lumber) across MDF, SPF Pine, Cedar, and Cellular PVC to account for real-world planing deviations (±1/32").
- Building Code Alignment: Clearance rules, fastener intervals, and dead-load specifications are cross-referenced directly with published standards from the International Code Council (IRC 2024 Chapters 7, 8 & 10), NFPA 211, and the American Softwood Lumber Standard (ALSC PS 20).
- Biannual Pricing Benchmarks: Material pricing tiers and prevailing labor cost indices are reviewed twice annually to reflect commodity lumber movements and regional installation averages.
3. Corrections & Peer Review Reporting
We are committed to absolute accuracy. If you notice a mathematical discrepancy, an unhandled edge case in room dimensions, an outdated building code reference, or a typographical error, we actively welcome your feedback:
- How to Report: Submit your observation directly through our Contact & Peer Review Form or email our technical desk at support@shiplapcalculator.com.
- Review Window: Formula inquiries are reviewed by our engineering and millwork audit team within 24 to 48 business hours.
- Correction Logging: When an algorithmic or informational error is confirmed, code updates are deployed to our repository, and substantively corrected pages receive an updated review timestamp.
4. Artificial Intelligence (AI) & Automation Disclosure
We believe in complete transparency regarding the tools used in our development workflow:
- Code Scaffolding & Tooling: Automated tools and generative models may assist in scaffolding front-end visualizers, formatting code, and generating initial linguistic translation baselines.
- Human Verification Mandate: No automated system is permitted to deploy formulas independently. All joinery trigonometry, rabbet deduction math, fastener load calculations, and safety warnings are manually verified against primary trade standards.
5. Commercial Independence & Anti-Bias Mandate
Shiplap Calculator is completely free to use. We do not accept sponsored product placements, paid tool endorsements, or biased material rankings from lumber mills, pneumatic nailer brands, or adhesive manufacturers. Our recommendations are determined solely by architectural durability, moisture tolerance, and physical installation performance.
