Construction and repair of commercial buildings or houses require constant awareness of moisture’s dangers. Water entering a building in an unintended location can cause rotted wood, mold, chipped paint, and many other problems. If not dealt with the right tools at the right time, a leak can cause tens of thousands of dollars of damage to an area that is already susceptible. It is therefore crucial to prevent moisture using crawl space moisture barriers.


It is not just rotted roofs and massive storms that can let moisture into commercial buildings. It can also develop from the ground up, causing damage that building owners may not even notice until it is too late. Crawl space moisture can cause severe damage

All of these problems can be solved easily with a crawl space vapor barrier.
