What is typically the first step in determining the full extent of water intrusion?

1. Identifying leaks

2. Examining insulation

3. Checking plumbing systems

4. Mapping out moisture sources

The correct answer is: Mapping out moisture sources

Determining the full extent of water intrusion often begins with mapping out moisture sources. This is critical because identifying where the moisture is coming from allows professionals to accurately assess the scale of the problem. Mapping involves understanding not only visible sources but also hidden areas that may contribute to water intrusion, such as roofs, gutters, walls, or foundations. By establishing a comprehensive map of moisture sources, assessors can pinpoint problem areas that need immediate attention or remediation. This foundational step supports all subsequent actions, including identifying leaks, examining insulation, and checking plumbing systems, as it provides a clearer picture of how and where water has penetrated the environment. An effective map also aids in prioritizing areas for further investigation or repairs, ensuring a thorough remediation plan is developed.
