How to Apply for a New Mold Remediation Worker Registration

A mold remediation worker is limited to performing mold remediation under the supervision of a licensed remediation contractor.

Application and Fee

To apply for a new Mold Remediation Worker Registration, submit a completed application form (Apply Online or see Mold Remediation Worker Initial Registration Application - PDF) along with the $50 registration fee.


You must be at least 18 years old at the time of application.

Submit with your application a copy of your initial mold remediation worker course certificate provided by a department accredited training provider or licensed mold remediation contractor.

Employer Requirements

Office in Texas

If you are currently employed by a company or individual that performs mold remediation, your employer must maintain an office in Texas.

You will be asked to provide your employer's license number (if applicable) on the application form.


You must provide a copy of your employer's certificate of insurance as evidence that the employer meets the requirement of maintaining a commercial general liability insurance policy in the amount of at least $1 million per occurrence.

You may be exempt from providing documentation of insurance if you meet any of the following conditions:

  1. You are currently unemployed. Before performing mold-related activities, you must provide the required proof of insurance coverage to the department.
  2. Your employer is licensed with TDLR as a Mold Remediation Company.
  3. You are employed by a governmental entity.
  4. You are employed by non-governmental entity that is considered "self-insured." Please submit to the department a signed affidavit stating that the employer has a net worth of at least $1 million. A current financial statement indicating a net worth of at least $1 million must accompany the affidavit.

Background Check

As part of the licensing process, TDLR will conduct a criminal history background check. You must pass this background check to be eligible for registration.

Having a criminal conviction will not necessarily disqualify you from registration. Please see the Guidelines for License Applicants with Criminal Convictions, which describe the process by which TDLR determines whether a criminal conviction renders an applicant an unsuitable candidate for the license, or whether a conviction warrants revocation or suspension of a license previously granted.

Temporary Registration

The purpose of a temporary mold remediation worker registration is to allow an individual to work while their background check is pending.

In order to receive a temporary registration, you must apply online for a mold remediation worker registration. The receipt from the online application will serve as your temporary registration. The receipt must be printed, and is required to be in your possession or on the job-site when performing mold-related activities.

The temporary mold remediation worker registration is valid for 21 days and may not be renewed. You must stop performing mold remediation services if you have not received your mold remediation worker registration before the temporary registration expires.
