Long-term solutions for preventing efflorescence and moisture problems include improving drainage around your home. Installing French drains, sump pumps, or exterior waterproofing membranes can be effective measures.
Consider applying a high-quality masonry sealer to your basement walls to prevent moisture infiltration. Regular use of a dehumidifier can also help maintain optimal humidity levels, reducing the risk of efflorescence and mold growth over time.

Consult a professional mold remediation service to handle significant infestations. They have the expertise and equipment to safely remove mold and restore the affected areas. DIY solutions may suffice for minor mold, but professional guidance is recommended for larger issues.
