How to Reduce Moisture in a Mobile Home

Mobile homes may develop interior moisture if the homes are not built correctly or if the interior home temperature causes condensation due to high humidity in the outdoor environment. Excess moisture can promote growth of wood-decaying fungi as well as harmful mould spores. Ridding a mobile home of excess moisture can be done by checking the design of the home and installing a dehumidifier.

Instructions

  1. 1

    Check the air ducts within the mobile home. Air ducts are typically located underneath the mobile home in the crawl space between the ground and the floor of the home. Air duct seals must be air tight to prevent outside air from entering the home, which can increase the amount of moisture in a mobile home, according to the Manufactured Housing Research Alliance.

  2. 2

    Seal the air ducts by surrounding the duct joint with several layers of electrical tape to ensure excess air is not leaking into the mobile home.

  3. 3

    Check the insulation in the walls of the mobile home if excessive wall moisture is present. The Manufactured Housing Research Alliance states that compression within wall insulation can create cold spots, which attract moisture. Insulation compression is caused by interior wall equipment pushing against the insulation, which creates pockets of air.

    An example of insulation compression is a wall outlet box pressed up against the insulation instead of cutting a portion of the insulation to accommodate the outlet box. Hire a contractor to remove the current insulation and replace with properly cut insulation.

  4. 4

    Install a dehumidifier within your mobile home to help remove excess moisture. Dehumidifiers work by extracting moisture from the air and collecting this water in a tank. The type of dehumidifier you need depends on the size of your room and the humidity level of your home. Areas with high humidity require a dehumidifier with a minimum capacity of 40 pints, which means it can remove 40 pints of air moisture every 24 hours.

Tips and warnings

  • If you believe excess moisture in your mobile home is due to a construction flaw, have a contractor review your home to determine what repairs can be done to get rid of the moisture.
  • By not quickly reducing moisture levels within your home, you run the risk of mould growth, which can be harmful to your health.
