If your previously-installed fire doors and openings are missing a proper certification mark, Intertek’s field labeling service helps you avoid potentially removal and replacement of unlabeled fire doors, frames and windows. Our experts will conduct a comprehensive review of all components in question and provide you with a written deficiencies report. We will work with you on modifications and corrections, provide re-inspection services and, when appropriate, provide the Warnock Hersey certification.
The Warnock Hersey Mark indicates compliance to appropriate national and local codes, standards and requirements. The Warnock Hersey fire door certification label is the most widely recognized in the industry, appearing on 70% of all fire doors found within North America.
