Martin E. Calderwood
Martin E. Calderwood is the editorial pen name used for this site’s homeowner-focused research and explanatory writing. The role is to organize technical subjects into questions, observations and decision frameworks that a non-specialist can use when speaking with qualified contractors.
The author identity is not presented as a licensed gas technician, electrician, plumber, refrigeration mechanic, engineer, building official or medical professional. Articles are educational summaries and are reviewed against manufacturer-level concepts and Canadian public information sources where practical.
Editorial approach
- Separate owner-safe observations from professional work.
- Avoid universal claims where climate, equipment and provincial rules differ.
- Use Canadian terminology, metric units where useful and Canadian public sources.
- Update or remove guidance that becomes misleading.
