Winter Moisture and Mold — How to Protect Your RV Before It’s Too Late

Cold weather brings more than just frost — it brings hidden moisture that can damage your RV from the inside out. Camper John’s RV Service & Repairs helps RV owners prevent mold buildup with mobile inspections and moisture control solutions tailored for winter conditions.

Why moisture is a threat in winter

  • Condensation builds up inside walls, especially when warm air meets cold surfaces.
  • Trapped humidity from cooking, showers, or breathing can seep into insulation.
  • Poor ventilation and sealed windows prevent moisture escape.
  • Frozen leaks or roof cracks allow water intrusion that goes unnoticed until spring.
  • Mold spores thrive in dark, damp areas, leading to health risks and costly repairs.

What Camper John’s offers

  • Mobile moisture inspections: We check walls, ceilings, and undercarriage for hidden dampness.
  • Seal and caulking checks: We identify and repair vulnerable entry points.
  • Ventilation upgrades: We recommend fan systems or dehumidifiers for better airflow.
  • Interior mold treatment: If mold is present, we clean and sanitize affected areas.
  • Winterization packages: Includes moisture control, propane checks, and insulation support.

Ideal for:

  • Full-time RVers overwintering in cold climates
  • Seasonal travelers storing RVs outdoors
  • Families using RVs for holiday trips
  • Anyone with older or poorly insulated RVs
  • RVs parked near lakes, forests, or humid zones

Tips to prevent mold this winter

  • Use moisture absorbers or dehumidifiers inside your RV
  • Crack windows slightly for airflow during cooking or showers
  • Inspect seals and roof before the first freeze
  • Avoid storing wet gear or towels inside closed compartments
  • Schedule a professional inspection before winter sets in
