Monitoring moisture levels around windows and doors is crucial for maintaining indoor air quality and preventing structural damage. Moisture intrusion can cause mold growth, rot, and other issues that compromise the health of your home and its occupants.

What Should Moisture Readings Be for Internal Walls?

Ideal moisture content varies depending on the material of the wall and its location within the building. In general, moisture readings below 16% are considered acceptable for internal walls made of gypsum board or wood.

Sources of Moisture Around Windows and Doors

* **Rainwater leakage:** Improperly sealed or damaged windows and doors can permit water to enter the building envelope.
* **Condensation:** Warm, humid air inside the home can condense on cold surfaces around windows and doors.
* **Rising damp:** Moisture from the ground can seep up through walls and foundations, eventually reaching windows and doors.

Consequences of Moisture Damage

* **Mold growth:** Excessive moisture can promote the growth of mold, which can cause respiratory problems and allergies.
* **Rot:** Moisture damage can degrade the structural integrity of wood around windows and doors, leading to costly repairs.
* **Energy loss:** Moisture-damaged insulation can reduce the thermal efficiency of your home, resulting in higher energy bills.

Monitoring Techniques

* **Moisture meters:** These handheld devices can provide accurate moisture readings in various materials.
* **Infrared thermography:** Infrared cameras can detect temperature differences that indicate moisture buildup.
* **Physical observations:** Check for visible signs of water damage, such as stains, discoloration, or peeling paint.

Prevention Measures

* **Proper sealing:** Ensure that windows and doors are properly sealed with weatherstripping and caulk.
* **Adequate ventilation:** Ventilate your home regularly to reduce moisture buildup.
* **Proper drainage:** Install gutters and downspouts to redirect rainwater away from your home.
* **Regular inspections:** Inspect windows and doors regularly for any signs of moisture damage.
* **Prompt repairs:** Address any leaks or moisture issues promptly to prevent further damage.
