Localized Moisture Problems and Their Causes

Localized moisture problems within internal walls require immediate attention to prevent further damage. Understanding their causes is crucial for effective remediation.

Causes of Localized Moisture Problems:

• Roof leaks: Water infiltration from damaged or poorly sealed roofs can cause moisture buildup within walls.
• Plumbing leaks: Burst or leaky pipes, faucets, or appliances can release excess moisture into wall cavities.
• Condensation: Warm, humid air can condense within walls, creating moisture buildup when it meets a cold surface.
• Groundwater infiltration: Poor drainage or high water tables can cause groundwater to seep into walls through cracks or foundations.
• Window or door leaks: Inadequate sealing around windows and doors can allow rain or snow to penetrate walls.

What Should Moisture Readings Be for Internal Walls?

Acceptable moisture readings for internal walls vary slightly depending on the material and building conditions. As a general guideline, moisture content should not exceed the following levels:

Higher moisture levels indicate a problem that requires immediate attention. If elevated moisture readings are detected, it is essential to consult with qualified professionals to identify and address the underlying cause.
