Why Encapsulation Matters in Fajardo
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 Fajardo 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 Puerto Rico
- !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)

How much does crawl space encapsulation cost in Fajardo, Puerto Rico?
Crawl space encapsulation in Fajardo, Puerto Rico typically costs $2,850–$7,750 for a complete system.

How long does crawl space encapsulation last?
A professional encapsulation system in Fajardo lasts 15–25 years. The vapor barrier itself (especially 20-mil reinforced products) can last 25+ years. Dehumidifiers should be serviced annually and replaced every 8–12 years. Most contractors offer transferable warranties of 10–25 years on the vapor barrier and 5–7 years on the dehumidifier.
