Common Questions

What is mold remediation, and what happens during it?

Answered from: Tex. Occ. Code Ch. 1958, EPA 402-K-01-001, IICRC S520

Answer

Remediation means removing mold and the materials it has damaged, cleaning what can be saved, and fixing the moisture that caused it. Texas law defines it as removing, cleaning, sanitizing, demolishing or otherwise treating mold-contaminated matter. EPA describes the goal as removing mold to prevent exposure and damage, not just killing it.

The usual sequence: fix the water problem; set up containment and protection; remove moldy materials that can't be cleaned; clean and dry what stays; then check the result. On a licensed Texas project, a licensed assessor writes a protocol first, the remediator gives the client a work plan before starting, and an independent licensed assessor performs clearance at the end.

What the sources say

“"Mold remediation" means the removal, cleaning, sanitizing, demolition, or other treatment, including preventive activities, of mold or mold-contaminated matter that was not purposely grown at that location.”

“It is necessary to clean up mold contamination, not just to kill the mold.”

“Fix the water or humidity problem.”

“The license holder shall provide the work plan to the client before the mold remediation begins.”

“Physically removing mold contamination is the primary means of remediation.”
