What causes mold growth?

Answer: Moisture.

Answer: Mold is caused by poor ventilation, high humidity, and warm temperatures.

Answer: Mold needs water to grow, and high humidity (moisture in the air) creates a perfect environment for it to thrive.

Answer: In a word, moisture. Fungus requires moisture to germinate and live. Moisture concentrations of 20% or more in wood will lead to sustained growth.

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

Answer: Moisture and poor circulation.

Answer: MOISTURE

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

Answer: Moisture intrusion, air, temperature

Answer: Spores need three things to grow into mold: nutrients - cellulose (the cell wall of green plants) is a common food for indoor spores; moisture - To begin the decaying process caused by mold.

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

Answer: moisture and heat

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) Moisture is really the key cause of mold growth since the other conditions on the list are always going to be present in homes. The difference between whether mold grows in your home or not comes down to whether you have a moisture problem.

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: Mold needs to grow a minimum small water leak, cellulose to start the spores grow up.

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: Moister and humidity

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: Moisture related issues are the primary cause of mold 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 and humidity.

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: Water

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 requires two things: mold requires water and a food source

Answer: excessive moisture

Answer: moisture

Answer: Moisture/humidity above 60%, food growth, warmth

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

Answer: Moisture problems

Answer: Mold requires moisture and a food source. With the addition of time, the likelihood that mold growth will begin increases. Many of the building materials used in homes are cellulose based and provide a perfect food source for mold when they are wet for extended periods of time.

Answer: Moisture & high relative humidity

Answer: Dampness and a food source.

Answer: Unwanted 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 from outside or water issues from inside, poor ventilation and many other causes

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

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

Answer: Moisture, High Humidity, Water Leaks

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: Sudden or long term moisture, condensation and humidity. Indoors, affected materials must be removed physically. The affected area and the remaining structure treated and dried within 24 hours or have the area professionally environmentally assessed by SafeHouse before letting anyone deploy fans to dry.

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: moisture

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

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

Answer: Mold generally needs elevated moisture levels to grow (50% and higher) and an organic surface to grow on.

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: Damp conditions

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

Answer: Moisture

Answer: Water and humidity are the ingredients for growing mold in any environment

Answer: Moisture

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

Answer: moster

Answer: Moisture

Answer: Cellulose, lack of air movement and moisture.

Answer: Excessive humidity.

Answer: Moisture is really the key cause of mold growth

Answer: Water and drywall
