Crawl Space and Mold a Problem

 crawl space and mold

Why is moisture accumulation so common in crawl spaces? Consider the location of the crawl space: it sits underneath your home right on top of the earth as your home’s foundation. Soil and dirt from the earth contain moisture. And moisture is one of two requirements for mold growth (the other being a food source such as the wood found in crawl space sub flooring). And since moisture forms so easily in confined areas, dirt crawl spaces are regular mold breeding grounds.

Moisture from dirt normally will evaporate into the atmosphere but can get trapped in a closed area like a crawl space. When moisture is not vented to the outside, it can start to condense on foundation walls or subflooring, which can be especially a problem if the sub flooring is wood (wood is a food source for mold).

Two other points to keep in mind about crawl spaces:

  1. Air travels from bottom to top. Thus, any moisture formed in crawl spaces will be carried by the moist air upwards to your living spaces naturally (or mechanically through the HVAC system), which can lead to mold growth beyond just the crawl space.
  1. You do not need standing water in crawl spaces to trigger mold growth. High humidity levels (above 60%) are enough to cause crawl space mold growth; And high humidity levels are very common in crawl spaces even in the absence of flooding!

At Southern Pest Control we offer Crawl Space Care.

CrawlSpace Care is a system that was developed for closing and protecting your home’s crawl space. Using innovative technology, the CrawlSpace Care system reduces moisture underneath your home, which can lead to low energy bills and improved indoor air quality.

The CrawlSpace Care system protects your home from the bottom up and controls moisture with:

  • High quality reinforced vapor liner to cover the ground and walls
  • Taped seams
  • Sealed foundation vents
  • Mechanical drying

With CrawlSpace Care, you’re protected against:

  • Condensational moisture
  • High levels of humidity
  • Ground moisture vapor
  • Moisture intrusion from inside of the foundation walls

The air in the crawlspace will be cleaner, improving the air quality in your home. You can even monitor the conditions of your crawlspace right from the comfort of your home with the thermo-hygrometer.

Mold/Crawlspace -Moisture Concerns

Mold/Crawlspace – What can be done to limit moisture buildup and crawl space mold? You may be have asked this question to yourself or asked others. We at Southern Pest Control would like to offer some tips that may can help you with your concerns.

  • Check the foundation walls and make sure there are no cracks where water can enter. Along these lines, check that there are no holes or cracks in the ceiling of your crawl space. These holes can be a gateway for mold and water transport from the crawl space to your living area.
  • Make sure gutters and downspouts channel away from the house. Otherwise, water can accumulate near the house and eventually find its way inside your crawl space.
  • Check for adequate ventilation. At a minimum, there should be 1 square foot of ventilation for every 150 square feet of crawl space area. Many building professionals now advocate closing vents and controlling moisture through other means.
  • In vented crawl spaces, insulate tightly against the sub floor. Secure the insulation snugly with mechanical fasteners. Do not just stuff the insulation up in the sub floor between the joists and hope it stays put. It will likely fall out eventually without fasteners. The vapor barrier portion of the insulation should face the heated source, which typically means upward against the subfloor.
  • Make sure existing insulation is not missing or sagging.
  • Make sure plastic sheeting covers the entire dirt crawl space and goes up a few inches alongside the foundation walls. There should be plenty of overlap between the layers of sheeting and the sheeting should be absent of any standing water.
  • Look for leaks around HVAC ducts and plumbing components.
  • Dryer vents should also terminate to the outside of the house and NOT into the crawl space.
