Mold remediation is defined by the State of Texas as the removal, cleaning, sanitizing, demolition or other treatment of mold. The Texas Mold Assessment and Remediation Regulations (TMARR) of 2005 mandates that a state licensed Mold Remediation Contractor (MRC) must have a mold remediation protocol prior to any mold remediation project, regardless of square footage. A protocol must be obtained for any mold remediation above 25 contiguous square feet of visible mold, unless you are the owner of a residential property with fewer than 10 residential dwelling units. 

Technically, where there is less than 25 contiguous square feet of visible mold, any unlicensed entity can conduct mold remediation and not be subject to the TMARR, which means a protocol would not be required. You should know that this exemption does not protect you from any liability or damages arising from an unregulated mold remediation. When an unlicensed remediator is used, a full Texas Mold Certificate cannot be issued. Significant health issues can be caused by unlicensed remediators removing mold without adequate containment (sealed plastic walls) and/or negative air.

Homeowners can remediate mold in their own home without being subject to the Mold Regulations. However, the homeowner should be aware of the potential health hazards that could be created should they try to remediate themselves without proper precautions.

A mold assessment (with or without mold sampling) report should not be confused with a Mold Remediation Protocol. The assessment report can be a standalone document and will satisfy the needs of many customers that undergo an assessment. However, the assessment report typically acts as the starting point for the more comprehensive Mold Remediation Protocol document. The Mold Remediation Protocol is a state-mandated document prepared by a licensed Mold Assessment Consultant (MAC). It’s required when the customer has chosen to use a State licensed Mold Remediation Contractor (MRC). 

It specifies the estimated quantities and locations of materials to be remediated, the remediation methods, and the clearance criteria for each remediation project. Basically, the protocol specifies the:

  • Location and causes of mold
  • Location and method of mold removal
  • Personnel requirements
  • Containment
  • Worksite security
  • Personal Protective Equipment (PPE) requirements
  • Clearance criteria

Each individual mold remediation project should have a customized protocol. Any hidden mold found after the initial scope of remediation in the Protocol should be placed in an Addendum to the Protocol and should specify what additional building materials should be removed (under containment). After the remediation is completed and a detail cleaning with 24-48 hour undisturbed air scrubbing occurs, a post-remediation inspection with air testing will be performed to ensure that no visible mold is present and that all clearance criteria has been met.
