Reader Help
For a question about a guide, start with its cited sources. For a question about your home, involve someone who can assess the actual conditions.
Check a statement
Each guide links its primary sources and shows its source-check date and review status. The source ledger gathers those documents in one place. Our corrections page records material updates and provides a downloadable note template.
Questions about your project
Use the contractor checklist to prepare a focused conversation with a qualified local professional. Contact the exact product’s manufacturer for its current label, safety documents, installation requirements, and support process. Your local building authority determines applicable permit and code requirements.
Editorial contact
