Moisture readings within internal walls should ideally be below 15%. Higher readings can indicate moisture ingress, which if left unchecked can lead to structural damage and health hazards such as mold growth.
**Reasons for High Moisture Readings:**
* Faulty or damaged windows or doors
* Poor ventilation
* Rising damp from the ground
* Leaking plumbing
**Consequences of High Moisture Readings:**
* Deterioration of building materials (e.g., drywall, wood framing)
* Increased risk of mold growth
* Structural damage
* Respiratory health issues
**Preventing Moisture Issues:**
* Ensure windows and doors are correctly installed and sealed.
* Maintain proper ventilation throughout the house.
* Address any sources of moisture, such as plumbing leaks or rising damp.
* Regularly monitor moisture levels using a moisture meter.
