Even though mold and mildew do not structurally damage wood, they will cause wood members to become more absorbent, which can allow moisture levels to reach critical levels of 26% to 28% or higher. Once these levels occur, decay fungus can set in.
  • Normal: 10-18%
  • Mold or Mildew: over 20%
  • Wood Decay: 28%

Step 2- Foundation Ventilation

Foundation¬†ventilation can be critical in limiting the amount of moisture accumulating in your crawlspace. Johnson Pest Control can determine the need to increase your crawl space ventilation. It is estimated that the soil of a crawlspace 30’x60′ can release nearly 40 gallons of water vapor per day.


Step 3- Crawl Space Moisture Barrier

The moisture barrier is usually compromised of sheets of 6 millimeter polyethylene (plastic). The sheets are laid in rows over the soil. The edges of the sheets are overlapped and tapped to form a continuous barrier that will trap the rising moisture. In most locations, the barrier is placed only over the soil and secured with weights. In some regions, the barrier is continuous over the foundation wall and secured to the sill plate.

  • Effectively decreases water vapor build up.
  • This vapor barrier is carefully installed over 75 – 80% of surface area in your crawlspace to prevent water vapor build up.
