Who typically installs the plastic vapor barriers for a pretreat?

The installation of plastic vapor barriers for a pretreat is typically the responsibility of the contractor. During the construction process, contractors are in charge of implementing various measures to ensure that the building structure remains protected from pests, moisture, and other potential issues. Plastic vapor barriers play a crucial role in preventing moisture from infiltrating the foundation, which can lead to various problems, including termite infestations.

While the applicator may handle chemical treatments and the inspector is responsible for evaluating the effectiveness and compliance of pest control measures, it is the contractor who manages the overall installation of vapor barriers as part of the building's foundation preparation. The owner, on the other hand, may have input on the construction, but the actual installation tasks are delegated to the contractor and their team, who are trained and equipped to implement these protective measures effectively.
