Best Mold Testing and Removal Companies in Dallas

Living in Dallas means dealing with constant humidity. The city sees average humidity levels above 60% throughout the year, and rain events happen regularly. This creates a perfect environment for mold growth in homes and businesses. If you’ve noticed musty smells, spotted discoloration on walls, or you’re preparing for a real estate transaction, you need professional help. But here’s something you should know: Texas law under the Mold Assessors and Remediators Occupational Code requires separate licenses for mold assessment and mold remediation on any single project. This means you’ll need to decide whether to hire a testing-only firm or a full-service provider handling different jobs. This article walks you through five Dallas-area companies that can help, whether you need inspection, testing, removal, or all three.

How to Select Top Mold Testing and Removal Providers

We evaluated these companies in early 2026 by checking Texas TDLR licensing records, IICRC certification databases, BBB filings, HomeAdvisor and Angi ratings, and customer reviews across multiple platforms. Here’s what we looked at:

• Texas Licensing: Testing firms must hold a valid TDLR Mold Assessment Consultant (MAC) license, while remediation companies need a separate Mold Remediation Contractor (MRC) license per state law.
• Scope of Service: We assessed whether each provider offers testing only, remediation only, or both services (though these must be separate projects under Texas law).
• Certifications and Experience: We favored firms whose staff hold nationally recognized credentials like IICRC or NATEC beyond state licensing.
• Turnaround Time: We checked how quickly each company can schedule on-site visits and return lab results, since delays let mold spread.
• Customer Reputation: We reviewed ratings on HomeAdvisor, Angi, Google, and BBB to gauge consistency, professionalism, and report quality.

Factors to Consider When Choosing a Mold Testing and Removal Company in Dallas

Testing vs. Full-Service Providers

Texas law prohibits the same company from performing both mold assessment and mold remediation on a single project. Decide upfront whether you need a dedicated testing firm, a remediation contractor, or a full-service company for independent jobs.

TDLR License Verification

Confirm your inspector holds a current TDLR Mold Assessment Consultant (MAC) license before booking. You can verify licenses for free using the Texas TDLR public search tool at tdlr.texas.gov.

Turnaround Time

Ask how quickly the company can schedule on-site visits and deliver lab results. Mold grows fast, so providers who can inspect within 24 to 48 hours and return results the next day meaningfully reduce your total remediation timeline.

Multi-Contaminant Needs

If your property was built before 1980 or involves demolition, choose a firm that tests for asbestos and lead too. Disturbing those materials without testing first creates serious legal and health risks.

Report Completeness

Request a sample report before booking. A quality mold assessment should include photos, moisture readings, lab results, identified mold species, and a clear remediation protocol, not just a summary or pass/fail result.

Final Thoughts

Before hiring any provider, verify their TDLR license. Unlicensed mold testing carries no legal standing in Texas and can void insurance claims. Match the provider to your situation: a quick residential inspection, a real estate transaction assessment, and a large commercial multi-contaminant survey each need different types of firms. Act promptly. Dallas’s humidity and heat mean mold can spread significantly within days of water intrusion, so delays between discovery and testing directly increase both health risk and remediation cost. Check credentials, compare turnaround times, and choose a provider whose services align with your specific needs.
