How Does Mold Spread?

The thought of mold in your house may be very disturbing. After all, mold spores can affect your household's overall health and safety!

Mold spreads in the same way other fungi do through airborne spores.

There are five factors that will cause mold to grow:

  • Organic food source

  • Time (48-72hrs)

  • Lack of air movement

  • Temperature (68 to 86) degrees

  • Moisture

Once mold has been established, it’ll begin to produce spores that spread through the air and attempt to colonize other areas of the house.

Mold spores easily travel through houses via air ducts, people, and pets. And when spores land in a space where conditions are right, they’ll begin to grow.

How Quickly Does Mold Spread?

In the right environment, mold can grow and reproduce quickly—in just 48-72 hours. How quickly mold grows depends on some of the factors listed above.

When all conditions are met, mold spores can settle and grow rapidly. When they reproduce, new spores are released into the air and can travel and settle in other areas of your home.

It’s a good idea to have regular home inspections to look for water damage and any visible mold growth, particularly after a flood. A home inspection can help you proactively correct mold-friendly environments before a problem occurs.

Be on the alert for visible mold and moisture in the following situations:

  • Water Damages

  • Sewage backups

  • Plumbing or roof leaks

  • Sump pump failures

  • Overflows from sinks or bathtubs

  • High humidity

  • Flooding

How to Get Rid of Mold Spores in a House

Mold spores travel through the air. If they land in ideal conditions, they’ll grow into mold and release more spores. Air filters and purifiers can help to remove spores from your property. But the best way to get rid of mold spores in your home is to prevent them from taking hold.

You can prevent mold growth at your property by:

  • Maintaining optimal humidity levels (between 30 and 50%) with an air conditioner or dehumidifier.

  • Quickly fix leaky roofs, windows, walls, or pipes.

  • Using a professional water damage remediation and mold removal services.

  • Ensuring proper ventilation in the shower, laundry, and cooking areas.

  • Keeping air filters clean and consider installing an air purifier.

  • Having HVAC ductwork professionally cleaned and maintained.

  • Monitoring potential problem spots like bathrooms, the laundry room, mechanical room, and basement.

  • Replace washing machine hose with steel braided hoses.
