How Much Moisture Does Mold Need to Grow?

If you’ve recently discovered a leak in your San Francisco home or office, you may be wondering if that wet spot on the floor is going to grow mold. Mold can spring up in as little as 24 hours after a puddle forms from a leaky pipe or A/C unit.

When in doubt, don’t wait. Address the moisture issue immediately and contact the trained mold remediation professionals at My Pure Environment right away. We know all about how mold grows, what mold needs to grow, what temperature and humidity level mold grows at, and how to prevent mold growth in your home or office.

What Temperature and Humidity Does Mold Grow At?

Mold grows fastest between 77°F and 86°F with relative humidity above 55%. It’s worth noting that mold can survive at almost any temperature. Colder temperatures simply cause mold colonies to go dormant, which limits spore production.

Coincidentally, temperatures between 77°F and 86°F are also the optimum temperatures for human comfort. In lieu of keeping the temperature in your home either blisteringly hot or freezing cold, the best way to control mold growth is by keeping the relative humidity low.

What’s the Best Humidity Level to Maintain Indoors?

Between 35% and 45% relative humidity will ensure that mold spores aren’t able to spread easily. However, if your air is too dry, it will be hard on the mucous membranes of your body. You’ll want to make sure that you’re living in a relative humidity of at least 35%.

Remember, mold grows best at a relative humidity of 55% so keeping the humidity well below that percentage is your safest bet. Most modern dehumidifiers have the ability to set a minimum humidity level. Set yours right around 40% to keep mold from growing in your home.
