RV water damage causes water stains. This deterioration may stem from a significant event like a water leak or roof leak or maybe from something as simple and unavoidable as condensation inside your camper. Water damage on the ceilings, carpet, and walls is the precursor to several issues if left unattended, primarily water stains and molding.
In addition to being unsightly, watermarks open the door for more significant issues with mold. Mold spores grow and thrive in damp areas, and leaving a water stain uncleaned leaves an optimal environment for mold growth.
Mold poses a risk to your health, as mold spores enter the air inside your RV, reduce the air quality, and have the potential to make you sick. Deal with watermarks promptly to prevent the risk of harmful soot spots of black mold or mildew.
