Why Encapsulation Matters in New Iberia
In the Southeast, vented crawl spaces draw in hot, humid summer air that condenses on cooler surfaces and feeds mold within 24–48 hours. Encapsulation is no longer "optional" here — most Southeast building codes now allow or require sealed crawl spaces. The combination of a sealed vapor barrier, vent caps, and a dedicated dehumidifier is the standard remediation.
What a New Iberia Encapsulation System Should Include
- ✓12–20 mil reinforced vapor barrier on floor and 6–12 inches up walls
- ✓Mechanical vent sealing on all foundation vents
- ✓R-10 to R-13 wall insulation (rigid foam)
- ✓Crawl space-rated dehumidifier (70–95 pints/day depending on sq ft)
- ✓Antimicrobial pre-treatment if any visible mold
- ✓Pest exclusion at sill plate and penetrations
What to Watch For in Louisiana
- !Avoid contractors who use thin (6-mil) plastic — it is not a long-term vapor barrier
- !Reject quotes that omit a dehumidifier — vent sealing without dehumidification can trap moisture
- !Confirm the warranty is transferable to the next homeowner (resale value)
