For corrections, identify the page, exact model and supporting manufacturer document.

Corrections

We welcome specific, evidence-based corrections. Identify the full page URL, exact manufacturer and model, the statement that may be inaccurate and a current manufacturer manual or other primary source supporting the correction.

Product updates

Amazon listings can merge variations or change sellers. If a button reaches a different product, include the page URL and visible ASIN. Do not send passwords, order information, addresses, payment details or other sensitive information.

Scope of responses

We can review published research and broken links, but we cannot select equipment for an unseen building, diagnose contamination, provide emergency restoration instructions or act as the manufacturer’s service department. Safety or code questions should be directed to a qualified local professional.

Useful reports

A useful message names the affected guide or product page and explains what happened: a broken destination, a mismatched image, an outdated model reference or a factual statement needing review. That level of detail lets us investigate without requesting private information about a visitor or property.
