You are installing a new vapor barrier, what happens to the old one?
/Our best practices are that the old vapor barrier is left in place and the new one is placed over it. The old barrier even if it does not cover the entire crawl space serves to provide some additional moisture blocking and also help protect your new vapor barrier from any rocks or debris on your crawl space floor. Additionally an old barrier helps keep the new one from getting dirty during installation.
If you prefer we can remove the old vapor barrier for an additional cost.
