Moisture on Materials

Moisture is a homes worst enemy. It causes mold to form on building materials that decomposes and as a result, lots of damage and of course illness. It is important to have a basic understanding of how moisture degrades a building structure.

How materials react to moisture depends upon many factors such as porosity, permeability, absorption, moisture holding capacity, evaporation rates and susceptibility to damage and microbiological growth. Although many building materials such as plaster, stucco and fiberglass are not generally conducive to mold growth, most others are. Below is a list of building materials and how moisture can affect them.

Mold can be successfully removed from Stucco but not from Sheetrock

  • Brick and Cinderblock: These materials do have high absorption characteristics, however, like concrete, they do not create a favorable growing environment for mold. It is important to make sure all mortar joints are properly tooled to help prevent water absorption. Once brick or cinderblock gets wet, it takes an extended period of time for them to dry out, which can cause mold to form when given the right set of circumstances.
  • Concrete: Concrete is one of the least predictable materials in the mold remediation industry. Not all concrete is the same. It comes in different thickness’ and some is more porous than others. Due to these variations, it is often unpredictable how concrete will act when moisture is introduced. Concrete does not create a favorable growing environment for mold, however, mold will grow on it especially when other building materials are in contact with wet concrete.
  • Drywall / Sheetrock: Drywall is extremely porous, which means it easily absorbs water causing mold to form. It’s an excellent source of food for mold and should be removed whenever left wet for more than 48 hours.
  • Glass, Plastic, Ceramic and Porcelain: These building materials are non-porous and mold rarely grows on them. However, moisture will often degrade these materials if left for long periods of time.
  • Metal: Metal building materials such as soffits and metal beams are non-porous, making them less susceptible to mold growth. However they do tend to rust when water is introduced for an extended period of time.
  • Insulation: Insulation is considered porous, therefore it easily absorbs water and should be replaced, not dried when wet.
  • Laminate Flooring: While the visible surface of laminated flooring is non-porous and does not invite mold growth, the underside is made of fiberboard and if this gets wet it will deteriorate and mold will grow.
  • Oriented Strand Board (OSB): OSB is similar to solid wood, therefore when the moisture content exceeds 16%, they should be removed rather than dried.
  • Particle Board / Fiberboard: These materials easily absorb water causing them to swell and loose their strength. Mold easily forms on these materials, therefore they should be replaced when wet.
  • Plaster and Stucco: These materials are similar to concrete and in most cases mold can be removed, restoring these surfaces to normal.
  • Plywood: Plywood is similar to solid wood, therefore when the moisture content exceeds 16%, they should be removed rather than dried.
  • Solid Wood: Examples are framing, flooring and trim. These materials are considered semi-porous and when the moisture content exceeds 16%, they should be removed rather than dried.
  • Vinyl Tile (VCT): While these materials are non-porous, meaning they do not absorb water, often water leaks through between the tiles causing trapped moisture below the floor. In these cases it is best to remove the tile to dry down the sub-flooring below.
