Overlooked crawlspaces outside, cause health concerns inside

FOR IMMEDIATE RELEASE
Annapolis, MD (August 27, 2011) -- As Hurricane Irene impacts the mid-Atlantic region this weekend, homeowners can expect significant flooding.  High winds, rain, and storm surge are three major concerns with this type of storm.  While it is easy to see the impact if storm waters enter the four walls, should you be concerned if the crawlspace floods?
 
"Absolutely!" says Todd Stevens, licensed inspector and owner of American Mold and Restoration in Maryland.  "There are several concerns when a crawlspace isn't dry or functioning properly. In homes with crawlspaces, approximately 40-60 percent of the home’s make-up air, and thus the air we breathe, comes from the crawlspace.  If it gets wet, a number of issues arise"
 
Flooded crawlspaces are a major source of indoor air quality complaints.  Wet lumber, soaked insulation, and water trapped on top of the crawlspace vapor barrier create an environment for mold and other fungal growth, as well as deterioration to the home’s structural components.  
 
As mold grows, airborne spores are drawn into the living environment from natural forces that pull and push the air from the crawlspace.  According to Stevens, the primary reason mold grows is because the crawlspace and building materials are wet or the humidity inside the crawl is high.
 
“There are a several things that a homeowner can do to reduce indoor air quality risks, as well as damage to the structure itself,” Stevens said.  “First, be safe.  Make sure standing water is removed and no dangers like hanging electrical lines exist. Then, get wet materials out as soon as possible.  Many emergency response companies are either not equipped or not willing to do this type of work, while AMR does.
 
“Next, improve drainage and ensure that ground water is abated making sure that the crawlspace is adequately dry prior to restoring the vapor barrier and insulation,” said Stevens.
 
While a flooded crawlspace can be disheartening and stressful, in most cases the crawlspace and home can be restored in relatively short order.  The key to a healthy living space is healthy crawlspace. Keeping the crawlspace dry and clean is necessary and achievable.
