Mold takes 24 to 48 hours to germinate and grow in ideal conditions (optimal temperature and humidity). A typical spore colony typically takes 3-12 days to colonize and has a visible appearance after 18-21 days. The time required for different types of mold to grow varies, depending on the conditions of each, the type of surfaces, the amount of moisture, the temperature, and so on. Regardless, the longer time passes, the greater the probability of mold developing and spreading to other areas of the house or other buildings.
It takes just a few hours for mold to spread. Moist organic materials attract mold spores, which grow in porous surfaces and feed on organic materials. Microorganisms attached to moist materials start spreading within hours, threatening the structural integrity of the materials. Mold quickly fills the air in your home with thousands of spores that spread throughout the building, affecting more and more surfaces as the days pass. Consequently, you will need to dry your home within 48 hours of an incident with water damage if you want to prevent mold from growing in your home.
Symptoms of Toxic Mold
Florida’s Department of Health states that toxic mold causes the following types of health problems:
Allergy and Irritation
Mold sensitivity may be higher in people with allergies. If they are exposed to mold, they might experience symptoms including:
- Runny or blocked nose
- Watery, red eyes
- Dry cough
- Skin rashes
- Sore throat
Shortness of breath can be a severe symptom of mold allergies.
For people with a strong immune system, mold is not an issue. Fungal infections are harder to treat in people with weakened immune systems, including those with HIV, transplant patients, and people undergoing chemotherapy.
