This is what long-term moisture intrusion looks like.
Dark staining, efflorescence, and visible mold growth along a basement foundation wall — all signs that water has been entering and sitting for some time. Mold doesn’t just stay on the surface. It spreads behind walls and into porous materials.
Professional remediation means proper containment, HEPA filtration, antimicrobial treatment, and fixing the moisture source — not just wiping it down.
Address the cause. Remove the contamination. Restore safely.
