John Lombardi, owner of John's Waterproofing, speaks about the hazards commonly hidden in basements and crawl spaces. John's Waterproofing is a basement waterproofing, basement remodeling and crawl space repair contractor serving the Portland, Salem and Eugene, OR area since 1974 as well as Vancouver WA.
John explains that below grade areas as extremely prone to water intrusion and moisture problems. In these areas, the Relative Humidity levels are often very high, well above 70% year round, and often above 100% at which point condensation occurs.
High humidity in these areas create the perfect conditions for mold and dust mites to grow. Mold spores and dust mite pellets are the two most common causes of indoor allergies in the U.S.
Because the air inside buildings always moves upwards, about half the air you breath in your home is coming straight from the basement or crawl space, along with the mold spores and any other harmful particles found in that environment.
Untreated crawl spaces and basements are unusable spaces. Wooden structures in these humid environments can eventually rot, or attract termites, eventually compromise the structural integrity of the house.
John urges area homeowners to take advantage of the FREE inspection his company offers and have their below grade areas professionally checked every six months.
