Which characteristic applies to semi-porous surfaces like floor joists after mold exposure?

Semi-porous surfaces, such as floor joists, have a unique composition that allows them to absorb some moisture without being fully porous. After exposure to mold, the potential for remediation largely depends on the structural integrity of the surface. If the structural integrity is intact, it is generally feasible to clean these surfaces effectively. Specialized cleaning methods and antimicrobial treatments can often eliminate mold spores and prevent regrowth, making it possible to salvage the material.

In contrast, if a semi-porous surface has been severely compromised or damaged by mold growth, it may be more challenging or even impossible to restore it adequately. However, as long as the structure itself is sound and the mold is addressed properly, these surfaces can be cleaned and preserved, which aligns with best practices in mold remediation.
