    The Hidden Costs This Calculator Doesn't Show

    • Mold remediation: $3,000–$10,000 per incident (every 3-5 years with fiberglass in humid climates). GaiaCrete™ = $0.
    • Energy savings: Hemp's thermal mass reduces HVAC costs ($800–$1,500/year).
    • Health costs: The average family spends $4,000+/year on health issues linked to poor indoor air quality.
    • Property value: Buyer demand for healthier, lower-energy homes is growing, though any resale impact depends on the local market and appraisal.
