Southeast — High Humidity pricing reflects local labor rates and climate-driven scope.

20-mil reinforced is recommended in this climate. Cheaper 6-mil or 10-mil sheeting will tear and degrade within 3–5 years under Southeast humidity.

A dedicated crawl space dehumidifier sized for 90+ pints/day is standard for 1,500–2,500 sq ft homes. Maintain humidity below 55% year-round — this is non-negotiable in the Southeast.
