Why Does Mold Grow In A Crawlspace?
Generally mold likes to grow in dark wet places. Therefore, your crawlspace can easily become a breeding ground for mold spores such as Stachybotrys (toxic black mold). Crawlspace mold can develop from several different moisture issues inside the crawlspace including:
- Cracks in foundation walls or exterior walls that allow additional moisture into the crawlspace.
- Leaky or frozen burst pipes.
- Condensation on the ductwork that contributes to high humidity and/or puddles.
- Items you are storing, insulation, or other crawlspace debris can promote mold by soaking up moisture.
- Gutter and downspout extensions that do not carry the water far enough away from the house for it not to enter the crawlspace.
- Rainwater can enter the crawlspace if the drainage of the yard slopes towards the house.
- Inadequate ventilation can hold excess humidity.
- Excess ground moisture evaporates into crawlspace due to lack of or improperly installed vapor barrier (link to crawlspace encapsulation).
Most crawlspace mold issues arise from several small issues that combine to form a major mold issue.
How Can Crawlspace Mold Be Prevented?
Since mold thrives in wet areas, the key to controlling mold growth is in controlling the level of moisture in your crawlspace. In most cases the humidity level in your crawlspace can be controlled with proper Crawlspace encapsulation(link) and/or crawlspace dehumidification. However, depending on the cause of the additional moisture, some situations may call for additional solutions such as a french drain system (link) or a Sump pump (link). Here are some general tips to preventing mold growth in your crawlspace:
- Keep crawlspace free of debris and check for missing or sagging insulation.
- Check foundation walls for crack where water could enter the crawlspace.
- Make sure downspouts and gutters channel away from the house.
- Look for leaks on plumbing components and HVAC unit.
- Make sure dryer vents terminate outside of the house.
