What causes mold growth?

Answer: Mold growth is primarily caused by excess moisture in indoor environments.

Answer: Moisture and poor circulation.

Answer: Moisture and poor ventilation

Answer: Water sitting either wet, drywall wood anything that can keep moisture barrier.

Answer: Moisture intrusion, air, temperature

Answer: moisture

Answer: When water and moisture come in contact with organic building materials.

Answer: moisture and heat

Answer: Moisture

Answer: Water

Answer: Mold is created by the moisture level in building materials. If the level is below 19% on a moisture meter, mold will most likely not be present.

Answer: Moisture

Answer: Moisture allows molds to grow, then they attach themselves to a food source.

Answer: Moist conditions and mold spores.

Answer: Heat and mositure

Answer: Moisture

Answer: In short WATER. Mold spores are everywhere, but without moisture it can not grow. That said even a little bit of moisture like condensation on an air vent may be enough.

Answer: High relative humidity or water intrusion and organic materials exposed to either.

Answer: Moisture, food source and ambient temperature are needed to cause mold to grow. Buildings and houses are maintained at suitable temperatures and are constructed with food sources, that mold desires to consume.

Answer: Extended exposure of building materials to water or moisture.

Answer: The primary ingredient need for mold growth is moisture. Eliminating the moisture source will stop the growth.

Answer: Mold grows when its spores float through the air and land on damp surfaces. Outdoors mold serves a natural function, helping to break down fallen leaves, twigs and even whole trees. Indoors, however, mold is capable of causing health problems for human beings.

Answer: Moisture and inadequate ventilation.

Answer: Moisture

Answer: Mold growth is cause by water and air. There are mold spores all around and they grow in moist warm areas.

Answer: Certain surfaces combined with moisture

Answer: Moisture

Answer: Mold needs these conditions before it can begin to grow in a home: Mold spores A food source (eg wood, drywall, cotton) Darkness (mold can't grow under ultraviolet light) Warmth (mold can't grow in freezing temperatures) Oxygen Moisture (eg water leaks, humidity) Enough time (most molds can begin to grow in 24-48 hours if the conditions are right)

Answer: Moisture and material to feed it.

Answer: Mold is caused by the prolonged presence of moisture.

Answer: Moisture in the air not being able to complete the "thermal Cycle".

Answer: Mold spores, 60-80% humidity, and a food source (cellulose materials)

Answer: Mold growth can occur in your home when there are elevated levels of interior moisture over a period of time.

Answer: excessive moisture

Answer: moisture

Answer: moisture, darkness and heat.

Answer: When there is moisture and warm air and substance for mold to grow on

Answer: Moisture problems

Answer: A combination of mold spores naturally occurring in the air and moisture, etc. that causes it to grow and multiply.

Answer: Moisture & high relative humidity

Answer: Dampness and a food source.

Answer: Moisture

Answer: Moisture levels above 20% can start spores in a growth. Controling moisture in a home is essential to control the growth of mold

Answer: Mold needs the same things as most forms of life, water food and warmth. The right combination can cause mold to grow rapidly.

Answer: Moisture, Lack of air movement & a growth media

Answer: Typically moisture that accumulates over an extended period of time

Answer: Moisture, proper growth medium and lack of ventilation.

Answer: Moisture, Food Source, Temperature, Spores

Answer: Mold can grow when there is a food source and adequate moisture. Different genuses of mold spores prefer different types of food and different amounts of moisture. The main limiting factor for mold growth is MOISTURE. Moisture can be in the form of liquid water or humidity. Different substrates (mold food sources) have different abilities to absorb moisture (water affinity) - this determines the optimum condition for specific mold growth conditions.

Answer: Water

Answer: Water source Cellulose material Moisture levels above 18% Humidity levels above 60%

Answer: There are 4 critical requirements for mold growth – available mold spores, available mold food, appropriate temperatures and considerable moisture. The removal of any one of these items will prohibit mold growth.

Answer: Moisture/damp conditions and a food source

Answer: Humidity water leaks

Answer: Moisture such as: water intrusion, condensation & plumbing leaks.

Answer: Moisture, organic food, (drywall, carpeting, dust...) heat, and lack of sun light.

Answer: Water intrusion and atmospheric conditions

Answer: Moisture & a food source for the mold

Answer: Mold generally needs elevated moisture levels to grow and a surface made of something it can consume.

Answer: Many conditions can cause mold growth but mostly humidity over 50 percent. Wet organic material can cause mold growth in as little as 24 hours.

Answer: Wet and moist areas. Plumbing, roof and structure leaks.

Answer: Moisture

Answer: Dampness and water intrusion.

Answer: Moisture

Answer: High Humidity, dust or organic materials, and low light or non light at all

Answer: Moisture

Answer: Moisture

Answer: Cellulose, lack of air movement and moisture.

Answer: There are many types of mold, and none of them will grow without water or moisture.

Answer: Moisture is really the key cause of mold growth

Answer: Water and drywall

Answer: Always a moisture source

Answer: moisture, bacteria

Answer: Water leaks, moisture, dampness

Answer: Moisture
