Humidity Levels and Mold Growth

Humidity, Dew Points, and the Myrtle Beach Climate

In order to understand the relationship between humidity levels and mold growth, we first need to understand that our South Carolina climate is considered “muggy” for 5.2 months of the year. If you live here, this is no surprise. You can sum up a Myrtle Beach summer in two words: hot and humid.

Humidity Levels in Myrtle Beach, South Carolina

We typically measure humidity with what’s known as the “Dew Point.” The dew point, simply, is the temperature at which water vapor condenses into liquid water. The dew point is a good indicator of how much moisture is in the air. In Myrtle Beach, lower dew points occur in the winter and higher, “muggier” days make up most of the weeks from May-October. Muggy weather, or weather with a high dew point, makes it easier for mold and mildew to grow.

Conditions for Mold Growth

Mold spores live and grow on and in organic material. Around your home this may be wood, carpeting, insulation, or paper. These organic materials are the “food” source for mold. Mold growth is not just a respiratory and health problem, it also can slowly destroy the structural integrity of walls, framing, and flooring.

While there are some molds that can thrive in cold temperatures, most mold thrives in warm, moist areas. For this reason, indoor mold growth can run rampant, especially in hot, sticky areas like an attic or a poorly ventilated room.

If mold spores grow and spread in these areas, a professional mold removal service is required. After successful remediation, the best way to prevent returning mold is to control indoor humidity and ventilation.

Signs of High Indoor Humidity and How to Control It

Indoor mold growth is often a clear sign of indoor humidity, but you may see other signs as well. Indicators of high indoor humidity include:

  • Condensation on windows, walls, and around plumbing
  • Mildew on kitchen or bathroom surfaces
  • Feeling sticky and uncomfortable indoors

High indoor humidity (and resulting mold growth) often means your HVAC system is inefficient. After mold removal by a professional service like MasterTech Environmental of Myrtle Beach, you’ll want to work with an HVAC company to address humidity, ventilation, and air circulation concerns.

As a result, using portable dehumidifiers are a good temporary solution. Used in poorly ventilated and humid rooms, dehumidifiers are inexpensive tools that will remove excess moisture from the air. Although this may take some of the work off your HVAC systems plate, it’s a temporary solution if the cause is poor air flow.
