Your crawlspace should be inspected by you or someone you hire at least once a year. Water intrusion, termites, water leaks and more can start up at anytime and create havoc and cost a bunch of money if not discovered in time. But if your crawlspace looks like this; crawling around the space is like a war zone! Who would attempt it if you did not have a immediate need to try and negotiate this unsafe space? So pay some young worker to clean out your crawlspace and make it easy to crawl around in. This floor is dirt. It is best to add a plastic vapor barrier to keep the ground moisture from entering your space and making it much nicer to crawl around on.
