In this photo, there is a balled up liner of some sort. Obviously not how it was meant to be laid out, but that's probably because whoever was trying to lay it out got frustrated. Installing these Liner can me very annoying and time-consuming, and that's just using basic liners which often do not get sealed. Our crews are experts at this, with many of our installers having over 10 years experience, they are able to knock these crawlspaces quicker than not.
