The short answer

First Steps After Water Damage

When you discover water damage in your RV or camper, the first step is to stop the water source. Turn off the water pump, close the valves, or disconnect from the hookup. If the leak comes from the roof, cover the area with a tarp to prevent more rain from entering. Move the vehicle to a dry, covered spot if possible.

  • Turn off water and electricity to the affected area
  • Remove cushions, mattresses, and fabrics
  • Sweep or mop up standing water
  • Use towels to blot wet carpets and upholstery
  • Set up fans and a dehumidifier
  • Wipe down hard surfaces with a mild cleaner

Drying Out the Interior

Drying an RV or camper is different from a house because the space is smaller and more enclosed. Moisture can get trapped in tight corners, under cabinets, and behind wall panels. Use a moisture meter if you have one to check for dampness in wood and insulation. If you don't, press your hand against surfaces to feel for cool, damp spots.

Pay special attention to areas where water may have wicked upward. Baseboards, cabinet bases, and the edges of the floor are common trouble spots. Use a wet/dry vacuum to extract water from carpets and upholstery. Keep the interior warm and ventilated for several days. If the weather is humid, run the air conditioner to pull moisture out of the air.

  • Check behind cabinets and under sinks
  • Remove access panels to inspect wall cavities
  • Lift carpet edges to see if padding is wet
  • Use a dehumidifier in a closed space
  • Wipe down metal surfaces to prevent rust
  • Prop up mattresses and cushions for air circulation

Assessing Structural Damage

Water can weaken the wooden frame of your RV or camper. Soft spots in the floor, warped walls, or sagging ceiling panels are signs of structural damage. Probe suspicious areas with a screwdriver. If the wood feels spongy or crumbles, it may need replacement. Check the roof for delamination or bubbling, which indicates water has penetrated the outer layer.

Inspect the seals around windows, doors, and vents. Dried or cracked sealant is a common entry point for water. Reseal these areas with a compatible RV sealant. If you find extensive rot or damage, you may need to replace sections of the frame or wall. That kind of repair goes beyond simple drying and may require professional help.

  • Look for soft spots in the floor
  • Check for bubbling or peeling on walls
  • Inspect the roof for cracks or delamination
  • Test window and door seals for gaps
  • Feel around vents and lights for moisture
  • Look for rust on metal brackets and screws

Dealing with Mold and Mildew

Mold can start growing within 24 to 48 hours in a warm, damp environment. If you see black spots, a musty smell, or discoloration, mold is likely present. Clean hard surfaces with a mixture of water and mild detergent. Avoid using bleach on porous materials because it may not kill the roots. For soft surfaces like carpets and cushions, professional cleaning may be needed.

If mold has spread into the wall cavities or insulation, the contaminated materials often need to be removed. This is not a job for a quick wipe-down. A mold professional can assess the extent and recommend safe removal. In the meantime, wear gloves and a mask when handling moldy items, and ventilate the area. If you feel unwell, see a doctor.

  • Wear gloves and a mask when cleaning mold
  • Ventilate the area with open windows and fans
  • Use a HEPA vacuum on moldy surfaces
  • Discard porous items that are heavily moldy
  • Wash non-porous items with soap and water
  • Keep humidity low to discourage regrowth

When to Call the Pros

Some water damage in an RV or camper is manageable on your own, but significant saturation or structural damage calls for experienced hands. Local water damage pros can assess how far the water has spread and what materials need to be replaced. They have the tools to dry wall cavities and the knowledge to prevent secondary issues like rot.

  • If water has soaked into insulation
  • If you notice a sagging ceiling or floor
  • If the electrical system has been wet
  • If mold covers a large area
  • If you cannot locate the source of the leak

Frequently asked questions

Can I dry out my RV myself?

You can dry small areas with fans and a dehumidifier. Remove all wet fabrics and open windows. However, if water has soaked into insulation or structural wood, you may not be able to dry it fully on your own. Professional equipment reaches deeper and prevents hidden mold.

Will my RV insurance cover water damage?

Coverage depends on your specific policy. Some policies cover certain types of water damage, like from a burst pipe, but not flood damage. Check your policy documents or contact your insurance company to ask about your situation. Policies vary, and your insurer decides what is covered.

How long does it take for mold to grow?

Mold can begin to grow within 24 to 48 hours after moisture exposure. That is why acting quickly is important. Remove wet items, increase airflow, and dry the space as soon as possible. If you see mold, clean it promptly to prevent it from spreading.
