Condensation within walls: Moisture can accumulate within wall cavities due to temperature differentials between the interior and exterior of a building. This condensation can lead to mold growth, structural damage, and insulation deterioration.
Subfloor moisture: Moisture can seep into subflooring from various sources such as groundwater, plumbing leaks, or high humidity levels. Over time, this moisture can cause warping, buckling, or rotting of the subfloor material.
Moisture trapped in insulation: Insulation that becomes saturated with moisture loses effectiveness and can create a conducive environment for mold growth. Moisture can enter insulation through leaks in the building envelope or through improper ventilation.
Moisture under flooring: Flooring materials such as hardwood, laminate, or tile can trap moisture underneath if not properly sealed or installed over a moisture barrier. This can lead to mold growth, warping, or delamination of the flooring material.
Roof leaks: Even minor roof leaks can allow moisture to penetrate into the building structure, leading to water damage and mold growth in areas not readily visible.
HVAC system issues: Malfunctioning HVAC systems can create moisture problems within ductwork or air handling units, leading to mold growth and poor indoor air quality.
High humidity levels: Excess humidity within a building can result from inadequate ventilation, improperly sized HVAC systems, or occupant activities such as cooking and bathing. Elevated humidity levels can promote mold growth and contribute to discomfort for occupants.
