Where In Homes Is White Mold Most Prevalent

Mold tends to thrive in dark, damp environments with a food source present.


Attics provide an ideal environment for white mold since they contain plenty of food sources such as wood and insulation. Leaky roofs, condensation from fluctuating temperatures, leaky pipes, and/or poor ventilation can provide mold with the moisture it needs to grow. Eliminating mold from attics can be particularly tricky due to the tight spaces. We recommend checking your attic occasionally for the appearance of white mold or a musty smell.


White mold in basements frequently grows on concrete walls, wooden floor joists and possessions stored there such as clothing. Water often seeps through basement walls to create a moist environment that is beneficial to mold growth. Cold outside air that comes in contact with warm indoor air in basements can also cause condensation making it a perfect breeding ground for white mold.

Its easy to confuse white mold in a basement with a substance known as crystalline efflorescence. Both substances grow in high humidity areas, but efflorescence isnt a type of mold. Efflorescence is a salt deposit left behind when moisture makes its way through concrete. In order to tell if it is white mold or efflorescence mist the affected area with water. If its efflorescence the salt with dissolve away. If youre still unsure, you should have a mold inspection, because mold can spread inside the walls and floor joists.

  • Warehouse: 34%
  • In most cases, mold growth can occur when the relative humidity levels range 65% to 99% in a given environment. However, when cold outdoor temperatures exist, conditions can form where even low amounts of humidity can condense on poorly insulated surfaces. This dew point is where water vapor becomes liquid and provides the conditions needed for mold growth to begin.

Mold in Insulation

  • Outside: 0 ppm
  • Warehouse: 0 ppm
  • Ideally, CO concentrations indoors are expected to be the same as CO concentrations outdoors. CO concentrations are typically around one to two parts per million parts of air or less. Concentrations are usually lower in rural areas. Finding CO concentration higher indoors than outdoors indicates an indoor source of CO, or a source very close to your home.
  • Carbon Dioxide :
  • Outside: 387 ppm
  • Warehouse: 779 ppm
  • The American Society of Heating, Refrigerating and Air-Conditioning Engineers recommends a concentration of CO2 no more than 700 ppm above the ambient air concentration in order to minimize human odors and maintain comfort.

Why Does Attic Mold Rarely If Ever Affect Indoor Air Quality In Homes

Its due to the simple fact that warm air rises in a house, this phenomenon is known as Stack Effect. Air rises from the lower levels of the home and up through the attic. Mold spores dont have wings, e.g., they cant fly against an upward flow of air from stack effect within a house, so its extraordinarily rare for attic mold spores to show up on indoor air quality mold tests. Therefore, it really isnt a per se health concern.

Mold On Attic Sheathing

Mold growth on attic/roof sheathing is a common issue in cool climates, such as the Pacific Northwest. In the vast majority of cases, the mold growth is caused by condensation. This occurs when the temperature of the sheathing drops below the dew point, creating a thin layer of moisture on the substrate. If this happens regularly, mold spores will activate and begin to grow.

  • Chest and nasal congestion
  • Watering, dry, or sore eyes

Respiratory Conditions

Symptoms like upper respiratory tract problems, coughing, wheezing, and shortness of breath are linked to respiratory conditions associated with mold. That is particularly concerning for healthy children who may go on to develop asthma or other types of respiratory illnesses.

Severe and Chronic Conditions

Certain types of mold can produce mycotoxins, which is a dangerous toxic by-product that can be absorbed by the skin, airways, and intestinal lining. Prolonged exposure to mycotoxins can lead to severe and even deadly conditions, including:

  • Cancer
  • Digestive and heart failure
