Who creates the content
Cost My Reno calculator logic and educational guides are produced under the Cost My Reno Editorial Team name. We do not claim professional licenses or field credentials that have not been independently verified. Where a topic requires project-specific engineering, code interpretation, hazardous-material work, or licensed trade judgment, we say so directly and refer readers to qualified local professionals.
How calculators are developed
We begin with dimensional geometry and unit conversions, then identify real purchasing units such as gallons, sheets, squares, bundles, boards, panels, or cubic yards. Rounding and waste allowances are shown rather than hidden. Every calculator includes a worked example, limitations, common mistakes, and sources that explain relevant practices or safety context.
How guides are researched
We prioritize government agencies, model-code organizations, established trade associations, and manufacturer technical documentation. A source is not copied into an article; it is used to check terminology, safety context, and established practice. Product instructions, approved plans, adopted local code, and the authority having jurisdiction remain controlling for a real project.
Review and corrections
Pages display a review date. We review content when formulas change, credible correction reports are received, or cited guidance materially changes. A correction request should identify the URL, disputed statement or result, reproducible inputs, expected result, and reliable evidence.
Advertising and commercial independence
The site is being reviewed for Google AdSense; display advertising is not currently served. If activated after approval, ads will be labeled and separated from navigation and calculator controls. Payment cannot change a formula, result, safety statement, recommendation, ranking, or source selection. Any future affiliate relationship will be disclosed beside the relevant link.
Use of automation
Software assists calculation, consistency checks, formatting, and site production. Published pages are expected to provide a complete user task, transparent reasoning, and source context rather than mass-produced summaries.
