Preventing Mold and Dampness in Mobile Homes

Dampness Prevention In Mobile Homes

Moisture problems in mobile homes arise not just from the water seeping through the roof leaks. Moist air can rise from the ground and appear through the openings in the walls, floors, and ceiling of the home as well.

When the moist air rising from the ground hits a cool surface, it condenses to form water droplets. If the surface is capable of absorbing the water, it will collect and build up with time. Indoor activities like showering and cooking can also cause moisture build up in manufactured homes.

If you wait until you see mold build up below window sill or feel a soft spot in the flooring caused by rotting of wood, then the fix can be an expensive one as you will need to pay for repairing the damage and to stop water leakage. Yet if you were a bit cautious with the same, you can prevent the issue in a few simple steps. Experts advise two ways to prevent dampness in manufactured homes:

  • Undertaking home improvement projects to make the manufactured home more moisture resistant.
  • Adjusting everyday lifestyle to decrease moist air formation inside the mobile home.

The simple improvement steps listed below will help you control formation of humidity and moisture in your manufactured home.

Install Ground Cover

HUD standards recommend having enough openings in the mobile home skirting to offer ventilation to the moist air rising from the ground, but experts say that the best preventive measure to stop accumulation of moisture is to use a ground cover. You may use a polythene sheet to prevent moisture build up. The ground cover need not cover every square inch of soil – you just need to cover the area that you can.

Seal Openings in Belly Board

Belly board is the plastic sheet that wraps the bottom of a mobile home and offers a moisture barrier for the bottom of the home. The belly board should be taken just as seriously as the roof of the home. Belly board can be torn in transportation, installation or it can be cut open to access the under floor plumbing.

Belly board openings can be sealed by installing a sheet of lightweight sheathing to the opening, fastening the area to the sheathing, and then applying a sealant to the edges. You may then cover the entire area with scrap belly board piece.

Seal Openings in Walls, Floor, and Ceiling

You may use caulk to seal small cracks around doors, windows, and ceiling light fixtures. If the openings are large, you may use an insulating foam sealant and this can provide a neat seam. In addition, special attention should be provided to the sealing around base of showers and bathtubs, else spilled water may leak through the floor and be trapped under it by the belly board.
