In Texas, 2025 marks a turning point for how environmental service companies operate and for how businesses must choose their mold inspection partners. With the signing of Senate Bill 1255, all mold testing and remediation work across the state now falls under stricter licensing and compliance standards.
For commercial property owners and facility managers, this change means that hiring the right inspection company is not just about speed and accuracy; it is now a matter of state law and regulatory compliance.
As temperatures cool and humidity levels shift this fall and winter, hidden mold growth becomes a greater concern for Texas businesses. Whether it is an office, warehouse, or retail space, ensuring your building’s air quality and compliance status has never been more important.
That is where DCG Environmental comes in, combining fast, licensed, and compliant testing with expert knowledge of the new Texas mold regulations under Senate Bill 1255.
Senate Bill 1255: A Major Change for Texas Mold Testing
Signed by Governor Greg Abbott and effective September 1, 2025, Senate Bill 1255 updates how mold assessment and remediation are regulated by the Texas Department of Licensing and Regulation (TDLR).
The biggest shift is that every employee who performs mold assessment or remediation work in Texas must now be individually licensed or registered.
Previously, only lead consultants or supervisors needed a license while employees could operate under their supervision. Now, no unlicensed worker can perform mold testing, sampling, or remediation.
Key points from SB 1255
- Employee Licensing: Every individual working on a mold project must hold a valid TDLR license or registration.
- Company Requirements: Mold assessment and remediation firms must maintain a one million dollar liability insurance policy and a physical Texas office.
- Consumer Transparency: Licensed assessors must provide the TDLR Consumer Mold Information Sheet to every client before work begins.
- Administrative Oversight: The TDLR is updating the Texas Administrative Code (Title 16) to reflect the new rules.
These updates were designed to raise industry standards, ensuring that all mold work in Texas meets consistent training, documentation, and safety benchmarks.
For business owners, that means one thing: choosing a licensed, insured, and compliant partner is not optional; it is essential.
Why Compliance Matters for Commercial Property Owners
SB 1255 shifts more responsibility onto property owners and managers. Under the new law, hiring unlicensed contractors or technicians could expose businesses to regulatory penalties and legal liability if testing or remediation work does not meet state standards.
Proper licensing ensures accurate testing from trained professionals, valid reports that hold up under inspection or insurance review, safety for building occupants and workers, and compliance with insurance and environmental requirements.
DCG Environmental has proactively adapted to these regulations. Every technician, consultant, and inspector on the team holds current TDLR-issued licenses, ensuring full compliance with SB 1255 and giving clients peace of mind that their inspection results meet state standards.
What This Means for Businesses Across Texas
If your company manages commercial properties, schools, hospitals, multifamily complexes, or industrial facilities, you now need to confirm that your environmental testing partners meet all new Texas licensing requirements.
DCG Environmental operates fully within these updated laws. With offices in Dallas, Austin, and Houston, the team of multi-licensed professionals can handle mold testing, asbestos inspections, and indoor air quality assessments quickly and compliantly.
The promise is simple: fast results, licensed professionals, and total transparency.
Commercial Mold Testing: How It Works Under the New Law
The testing process itself has not changed, but who performs it has. Under Senate Bill 1255, each step must be carried out by a licensed individual using approved sampling and documentation methods.
Here is what a compliant commercial mold inspection looks like with DCG Environmental.
- Visual and Moisture Inspection
- Inspectors perform a detailed walkthrough, focusing on high-risk areas where water sources may be.
- Air Sampling
- Air samples are collected from from one to multiple zones and compared to outdoor baselines to identify hidden contamination.
- Surface Sampling
- Swab or tape-lift samples are taken from visible or suspected mold growth for lab analysis.
- Laboratory Testing
- Accredited laboratories analyze all samples to confirm species and spore concentration levels.
- Comprehensive Reporting
- A clear, easy-to-read report is provided that meets all TDLR reporting and record-keeping standards.
These steps, when performed by licensed professionals, ensure compliance and credibility that are crucial for insurance claims, tenant communications, and legal protection.
The Cost of Testing vs The Cost of Non-Compliance
The cost of a professional commercial mold inspection varies depending on building size, number of samples, and project complexity. But under SB 1255, the cost of hiring an unlicensed provider can be far higher.
Non-compliant work can lead to voided insurance coverage, invalid test results or remediation plans, project delays, and fines or penalties for regulatory violations.
Partnering with a TDLR-licensed company like DCG Environmental eliminates those risks and ensures your documentation and results meet all state requirements.
Asbestos Regulations: What Has Not Changed
While mold regulations underwent major changes in 2025, Texas asbestos laws remain largely consistent.
The Texas Department of State Health Services (DSHS) continues to regulate asbestos licensing, requiring advance ten-day notifications for all facility or public building demolitions, annual refresher training for all licensed asbestos workers and supervisors, and medical surveillance documentation for active licensees.
DCG’s licensed asbestos inspectors and air monitoring technicians follow all DSHS and NESHAP standards, providing a one-stop resource for full environmental compliance in Texas.
Why Fall and Winter Still Matter
Even with new licensing rules in place, seasonal mold risk has not gone away.
Cooler months create conditions for moisture to linger in commercial buildings: HVAC condensation as systems switch from cooling to heating, reduced ventilation in sealed offices and retail spaces, and leaks from fall storms or early freezes.
Hidden mold growth can spread behind walls, ceilings, or ductwork long before it becomes visible. Combining seasonal awareness with regulatory compliance is the smartest move a property manager can make this year.
