Why Encapsulation Matters in Summerlin South
The Southwest is dry, so full encapsulation is less common — but a vapor barrier and vent sealing still matter. Soil gas (radon, methane), occasional monsoon flooding, and pest infiltration are the real drivers here. Many homes do a "partial encapsulation" (barrier + vent caps, no dehumidifier) which costs significantly less.
What a Summerlin South Encapsulation System Should Include
- ✓10–12 mil vapor barrier (lighter mil acceptable due to low humidity)
- ✓Vent sealing with operable summer/winter caps
- ✓Pest exclusion at all penetrations
- ✓No dehumidifier needed in most cases — climate handles it
- ✓Foundation repair if expansive-soil cracks exist
- ✓Monsoon-season drainage if flood plain
What to Watch For in Nevada
- !Be skeptical of contractors selling full encapsulation packages (with dehumidifiers) in dry Southwest climates — partial encapsulation is usually right
- !If your soil tests positive for radon, upgrade to 20-mil radon-rated barrier
- !Check for expansive-soil cracks before barrier installation — cracks shift the substrate and tear cheap barriers

How long does crawl space encapsulation last?
