Understanding Mold Growth After Water Damage

Moisture, time and food — the three things mould needs, and how to take them away.

What mould needs

Mould needs moisture, an organic food source such as drywall paper or wood, and suitable temperatures. Homes provide plenty of food and warmth, so moisture is the factor you can control.

How fast can it grow?

Under favourable conditions, mould can begin to grow on damp materials within roughly 24 to 48 hours. That is why prompt drying is so important.

Inspection vs. remediation

Inspection determines whether there is a mould or moisture problem. Remediation contains and removes affected materials and addresses the moisture source.

A note on health

Some people are more sensitive to mould than others. If you have health concerns, speak with a medical professional.
