In many ways: tiny cracks in the floors, around air registers, space around plumbing pipes, heating and air conditioning ducts – especially return air ducts. In fact research shows that up to 50% of the air in your home comes from your crawlspace. This infiltration brings with it odors, moisture, mold mildew, fungi spores or radon gas that is in your home’s crawlspace.
Dirt crawl spaces provide a dark, damp, dirty environment that is rich in organic materials. These are exactly the conditions needed for molds, fungi, and other microbes to thrive. Many of these molds and fungi can cause illness or irritation as their spores drift up into the home's living space (individuals with allergies, asthma, and other respiratory conditions are especially vulnerable).
These rodents are burrowing animals and they often enter the home under footings and into the crawl space. A concrete floor is an impenetrable barricade.
These insects can not be detected in the early stages of invasion without the special equipment. Termites have the ability to go undetected within your home, sometimes for years, eating away at the structure. Their stealth tactics of eating wood, when outwardly it looks completely uninjured, are the cause of their late discovery
Sometimes cracks occur from settling, and usually happen within the first three years of the home. Horizontal cracks may need structural repair, but most cracks are vertical and do not affect the compressive strength of the foundation. However, cracks on outside walls are subject to water seepage and should be repaired.
