Martinez Crawl Space Encapsulation
The Martinez home had a dirt-floor crawl space with chronic moisture problems. Relative humidity regularly exceeded 80%, leading to mold growth on floor joists and a persistent musty smell throughout the first floor. We performed a full encapsulation with a 20-mil vapor barrier, installed a commercial-grade dehumidifier, and sealed all foundation vents to create a conditioned crawl space.

Project Outcome
Crawl space humidity dropped from 82% to a steady 45% within two weeks of project completion. Independent mold testing six months later confirmed zero active growth. The Martinez family reported that the musty odor was eliminated entirely, and their HVAC system now runs more efficiently, reducing their monthly energy bill by approximately 15%.
