Not recommended for significant water intrusion (Category 2 or 3 water) or areas affecting structural elements, electrical, or plumbing systems due to health risks, potential for hidden damage, and the necessity of specialized equipment for proper drying and remediation to prevent mold and structural degradation. Professional intervention is critical for code compliance and long-term safety.
The process requires specialized knowledge and equipment to prevent secondary damage (e.g., mold) and ensure structural integrity and code compliance, but typically precedes major structural reconstruction. Multiple trades may be involved, necessitating coordinated efforts and adherence to specific codes.
