What Makes a Crawlspace Smell Like One?

Thursday, July 9th, 2015 by Fraser Hay


If you own a home with a crawlspace, chances are you have noticed a damp musty odour coming from the crawlspace, or on the boxes removed from the crawlspace.  The answer is quite simple.  Mould!  Mould can even grow in a "Waterproofed Crawlspace". 

Mould needs organic material to grow (which many crawlspaces are full of.  Boxes, Insulation, drywall, carpet etc.), and high relative humidity - over 55-65%.  It does not have to be wet fro mould to grow, just humid.  In fact mould will not grow under water.

A proper air systems such as the Sani-Dry systems ensures that relative humidity stays below 55% all year long so mould does not have a chance to grow.  Proper encapsulation and keeping the humidity levels low will help eliminate those damp musty odours in your crawlspace.
