Atlanta Crawl Space Waterproofing – Dry-Tec® Closed Crawl Space System
Crawl space encapsulation is critical for homeowners because it seals off the area beneath the home from moisture, outside air, and ground vapor — the primary causes of mold, wood rot, structural damage, and poor indoor air quality. In humid climates especially, open crawl spaces allow moisture to enter through vents and foundation walls, creating the perfect environment for deterioration and unhealthy air.
Since a large portion of the air inside your home rises from the crawl space, untreated humidity and contaminants don’t stay below — they circulate throughout your living areas. Professional encapsulation creates a controlled, dry environment that protects floor joists and support beams, improves energy efficiency, reduces musty odors, deters pests, and helps prevent costly repairs.
Simply put, crawl space encapsulation protects your home’s structure, your air quality, and your long-term investment.
BEWARE OF THE OTHER COMPANIES that use cheap plastic, low grade scrim that will result in major off-gassing issues in your home!
