Uncontrolled moisture in building walls is an unwelcome problem with severe implications. Understanding its consequences is crucial for timely remediation. Structural Damage Weakened structural elements like framing and drywall due to softening and deterioration. Collapse or severe structural failure if moisture advances unchecked. Health Hazards Mold growth and associated respiratory issues such as asthma, allergies, and infections. Damp and musty conditions attract pests, increasing the risk of health hazards. Deteriorated Wall Coverings Blistering, peeling, or cracking of paint, wallpaper, or other wall finishes. Weakened bonds between finishes and the underlying wall, leading to premature failure. Energy Loss and Higher Utility Costs Moisture-damaged insulation loses its effectiveness, resulting in higher heating and cooling costs. Damp walls contribute to heat loss, increasing the need for space heating. Aesthetic Damage Stains, discoloration, and efflorescence (salt deposits) on wall surfaces. Unpleasant odors emanating from moisture-damaged areas. Prevention and Control How much moisture is OK in walls? Typically, less than 15% moisture content by weight. Proper ventilation and moisture control measures, such as exhaust fans and dehumidifiers. Timely repair of leaks, faulty plumbing, and damaged building envelopes. Professional moisture inspections and remedial action if necessary. Conclusion Ignoring trapped moisture in walls can have serious consequences [...]
