Professional TDLR-licensed mold remediation following IICRC S520 standards. HEPA containment, antimicrobial treatment, post-remediation lab clearance testing. We handle the work most companies aren't licensed to legally perform in Texas.
Mold remediation in Texas is regulated under Texas Occupations Code Chapter 1958 and overseen by the Texas Department of Licensing and Regulation (TDLR). For any mold remediation project affecting more than 25 contiguous square feet, Texas law requires:
This separation protects homeowners from a common scam: companies that inflate mold problems to sell unnecessary remediation. We work with independent TDLR-licensed Mold Assessment Consultants for the assessment, then perform remediation as the licensed MRC. Both reports become permanent property records, useful for future real estate transactions.
Houston's subtropical climate makes mold remediation a year-round business. Our 70%+ average humidity, 50+ inches of annual rainfall, and history of catastrophic flooding mean mold colonization is more aggressive here than in any other major US city. Common species we encounter include Aspergillus, Penicillium, Cladosporium, and the more dangerous Stachybotrys chartarum (commonly called black mold) — especially after untreated water damage events.
Critical timing: Mold spores germinate on wet drywall and insulation within 24-48 hours of water exposure. If you have a leak, flood, or burst pipe, prevent mold by calling water damage restoration immediately — don't wait for visible mold to appear.
Following ANSI/IICRC S520-2024 protocols plus Texas TDLR requirements.
A TDLR-licensed Mold Assessment Consultant (MAC) inspects, takes samples, and prepares a written Mold Assessment Protocol — the legal scope document for remediation.
Polyethylene sheeting seals the work area. HEPA-filtered air scrubbers establish negative air pressure, preventing spores from migrating to clean areas during removal.
Remediation cannot succeed without fixing the moisture source. We identify and address the underlying leak, humidity issue, or flooding cause.
Contaminated drywall, carpet padding, insulation, and ceiling tiles cannot be cleaned — they must be removed. Workers wear Tyvek PPE and respirators throughout.
HEPA vacuums remove remaining spores. EPA-registered antimicrobials treat non-porous surfaces. Air scrubbers run continuously throughout the process.
Independent lab analyzes air and surface samples after completion. Clean clearance results legally close the project and provide documentation for future real estate disclosure.
TDLR-licensed MAC visual inspection, thermal imaging, moisture mapping.
AIHA-accredited lab analysis with spore identification reports.
Stachybotrys chartarum removal with Level C PPE and strict containment.
The most common cause — leak, flood, or burst pipe followed by mold colonization.
Specialized work after Houston flood events with Cat 3 contamination context.
NADCA ACR Standard HVAC mold remediation for whole-system contamination.
Subtropical humidity, repeated flooding, and aging housing stock combine to make Houston one of the worst mold markets in the country.
Our 70%+ average humidity sustains mold growth year-round — there's no "dry season" that resets the moisture conditions like in arid climates. Combined with hurricane season (June-November), winter freeze events that burst attic pipes, and the catastrophic flooding events Houston has experienced — Allison, Memorial Day Flood, Tax Day Flood, Harvey, Imelda, Beryl — our properties are repeatedly subjected to water intrusion that creates mold conditions.
Post-Harvey, Houston experienced what some public health officials called a "mold epidemic." Tens of thousands of homes were flooded, but only a fraction were properly remediated. Many homeowners attempted DIY cleanup with bleach (which doesn't kill mold roots) or hired unlicensed "remediators" who simply painted over the problem. Years later, those same homes are still presenting with chronic mold issues — and many residents have developed respiratory problems.
Texas TDLR licensing exists specifically because of these scams. The state separates assessment from remediation precisely to prevent companies from over-diagnosing problems to sell more work. When you hire a TDLR-compliant team like ours, you get an honest assessment from an independent MAC, followed by legitimate remediation we can defend in any future real estate transaction or insurance dispute.
Most Texas homeowners policies offer limited mold coverage — typically $5,000 to $10,000 — only when mold results from a covered water damage event (burst pipe, appliance leak, sudden plumbing failure).
Coverage exclusions are common: mold from gradual leaks (slow drips going unnoticed), humidity issues, flooding (separate NFIP territory), or poor maintenance is typically not covered. We help determine your actual coverage before work begins and document everything for your adjuster.
We review your policy before work begins so there are no surprises
We tie mold back to the covered water event to maximize coverage
Third-party assessment carries more weight than self-issued reports
Legal closure that protects future real estate transactions
Mold coverage varies — we check yours first
"Three different companies told us we needed a full mold remediation that would cost $40K. The MAC inspector they brought in determined only one room was actually affected. Total cost ended up being $4,500. Honest people in a dishonest industry."
"Black mold from a slow leak we never noticed. The TDLR-licensed assessor, the protocol, the remediation, the clearance test — all coordinated by them. Our pediatrician confirmed our daughter's asthma symptoms improved after the work."
"Post-Harvey mold in our Meyerland home — discovered when selling. They had it cleared in 6 days, clean clearance report in hand, and we closed on time with no buyer concerns. Saved the deal."
Yes for any project over 25 contiguous square feet. Texas Occupations Code Chapter 1958 requires a TDLR-licensed Mold Assessment Consultant (MAC) for the assessment and a separate TDLR-licensed Mold Remediation Contractor (MRC) for the work. The same company cannot legally both assess and remediate the same project. Smaller projects under 25 sq ft don't require TDLR licensing but should still follow IICRC S520.
Most Houston mold remediation projects take 3-7 days total: containment setup (1 day), active remediation work (1-4 days depending on extent), and post-remediation clearance testing with lab results (3-5 business days). Major flood-related mold remediation can take 2-3 weeks.
Coverage varies. Most standard Texas policies offer limited mold coverage ($5,000-$10,000) when mold results from a covered water damage event. Mold from gradual leaks, humidity, or flooding is typically excluded. We help determine coverage before work begins and document the water source to maximize available coverage.
No, and this is one of the most common DIY mistakes. Bleach kills surface mold but doesn't penetrate porous materials where mold roots grow. The water content in bleach can actually feed deeper mold growth. EPA and the IICRC do NOT recommend bleach for mold remediation. Professional EPA-registered antimicrobials and proper porous material removal are required.
Stachybotrys chartarum produces mycotoxins that can cause respiratory problems, allergic reactions, and aggravate conditions like asthma in sensitive individuals. The "toxic black mold" cultural narrative is partly overhyped, but the underlying health concerns are real — especially for children, elderly, immunocompromised individuals, and people with respiratory conditions. Remediation should be handled professionally with Level C PPE.
Houston's humid climate makes mold inevitable after untreated water damage. We provide free initial inspections and only recommend remediation if it's truly needed — backed by independent MAC reports.
