What is the first step in preventing moisture intrusion in a home?

Preventing moisture intrusion in a home starts with focusing on water intrusion prevention. This involves identifying and mitigating sources of water entry to protect the structural integrity of the home and the health of its occupants. Proper water intrusion prevention measures may include ensuring proper grading around the foundation, installing drainage systems, and maintaining gutters and downspouts to direct rainwater away from the home's surfaces. Addressing these potential entry points effectively reduces the risk of moisture buildup, which can lead to mold growth and damage over time.

Ventilation, sealing air leaks, and providing moisture escape are all important methods in moisture management, but they come as subsequent steps that support the primary goal of preventing moisture from entering the structure in the first place. These methods can enhance the overall effectiveness of the moisture control strategy but should not be viewed as the foundational step.
