While mold is essential in maintaining the environment’s natural balance, indoor mold can cause health issues and property damage. You can stop the growth of mold in your home by learning a few facts about mold growth. Here’s everything you need to know about what causes mold to grow in homes like yours.


Mold Requires Specific Conditions to Grow

  • Spores
  • Darkness – (Mold will not grow in ultraviolet light.)
  • Warmth
  • Oxygen
  • Moisture – water leaks, humidity, etc.
  • A Food Source – wood, drywall, cotton, etc.

All of these conditions are easily found in any home. The exception: moisture. Moisture is the real answer to “what causes mold to grow?” Without moisture, mold simply will not grow.


Common Causes of Moisture in Your Home

Humidity – Humidity is, in essence, moist air. If that moistness has a chance to settle into your home, then mold has a chance to grow. Keep your home well ventilated and try to keep the humidity level below 50 percent.

Leaks – Leaks from faulty pipes or a rotting roof can cause mold. Often, water damage hides inside your walls or roofline, unseen. Check for water damage frequently, and if you experience a suspicious loss of water,  check for a leak or pipe break. Before purchasing a home, hire a certified inspector to examine your roof. If the roof needs replacing, mold will likely be present.

Insufficient Ventilation  If your air isn’t moving, it’s creating humidity. Use fans if needed, and open doors and windows to help ventilate a space so that stagnant air doesn’t have a chance of settling moisture.

Condensation – Condensation will be visible, whether it’s on the windows, walls, or elsewhere. If there’s condensation in your home, then there’s a humidity problem, and the moisture will lead to mold.

Wet Clothing – Leaving wet clothing lying around is a great way to invite mold into your home. Never leave your damp laundry sitting around in your home, and make sure your dryer is properly vented.

Flooding – Flooding can cause a significant amount of damage, some of which will remain unnoticed to the untrained eye. Mold can grow within 24 to 48 hours of a flood, and the longer water is left standing, the more opportunity mold has to develop.

Foundation Grading Issues – The ground around your home should slope away from your foundation. If your grading slopes towards your foundation, you’re leading the water straight into your foundation. This can cause flooding, dampness and stagnant water buildup, all of which create the perfect environment for mold to grow.
