Sunshine Home Inspection found this very large termite tunnel.  You don't see them this big very often.  Our home inspection revealed this 5 inch wide tunnel going up the pier to this raised home.  It's the muddy vertical area going up the brick pier in the middle of the picture.  These little critters caused extensive damage to the structure under the home and in the attic.  We also saw several studs that were eaten away.  We estimated around 30,000 to 40,000 dollars worth of work to repair this home.  Maybe more after you start digging into things.  Home inspections are certainly worth the $400 that we charge.
