Crawl Space Moisture & Support Solution in Loudon, TN

Challenge

A homeowner in Loudon, Tennessee, was concerned about excessive humidity and sagging floors in their crawl space. The area was unsealed, poorly insulated, and lacked adequate structural support — all of which contributed to moisture buildup and long-term risk to the home’s foundation. The homeowner wanted a permanent solution to protect their investment and improve the stability and health of the space beneath their home.

High moisture levels can lead to mold growth, wood rot, and musty air creeping into the living space. Additionally, the sagging joists were beginning to cause uneven floors and creaks above. It was clear that this crawl space needed a total overhaul.

Solution

Our crew at Master Services began by installing a professional-grade dehumidifier system to actively manage humidity levels and improve air quality. We then encapsulated the crawl space with a durable vapor barrier to seal out ground moisture. Reflective insulation was applied to the walls to help regulate temperature and improve energy efficiency.

To address the sagging structure, we installed SmartJack® support posts beneath the floor joists, lifting and stabilizing areas that had weakened over time. This combination of moisture control, insulation, and structural reinforcement gave the homeowner exactly what they were looking for — a crawl space that’s dry, clean, and strong. 

Thanks to the comprehensive system we installed, this Loudon crawl space is now protected against moisture and structural damage. The homeowner has peace of mind knowing their home is supported from the ground up — literally.
