What causes mold growth?

Answer: Moisture and poor circulation.

Answer: Moisture and poor ventilation

Answer: MOISTURE

Answer: Moisture intrusion, air, temperature

Answer: moisture

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: moisture and heat

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) 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: 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

Answer: Moist conditions and mold spores.

Answer: Heat and mositure

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

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: Moister and humidity

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: Moisture related issues are the primary cause of mold growth.

Answer: Moisture and inadequate ventilation.

Answer: Moisture

Answer: Moisture and humidity.

Answer: Certain surfaces combined with moisture

Answer: Moisture

Answer: moisture

Answer: Moisture and material to feed it.

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

Answer: Water

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: Mold requires two things: mold requires water and a food source

Answer: moisture

Answer: moisture, darkness and heat.

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

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: 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: Dampness and a food source.

Answer: Moisture

Answer: Unwanted moisture

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

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

Answer: Moisture, Food Source, Temperature, Spores

Answer: Moisture, High Humidity, Water Leaks

Answer: Water

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

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: Moisture/damp conditions and a food source

Answer: Humidity water leaks

Answer: moisture

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

Answer: Water intrusion and atmospheric conditions

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

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: Damp conditions

Answer: Moisture

Answer: Dampness and water intrusion.

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

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

Answer: Moisture

Answer: moster

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: Excessive humidity.

Answer: Water and drywall

Answer: Always a moisture source

Answer: Dampness, moisture, and water intrusion.

Answer: Water leaks, moisture, dampness

Answer: Moisture

Answer: moistrue and lck of light
