Mold Remediation and Mold Removal in Tyler, Longview & East Texas

What are the signs of mold in a home?

The most common signs are a musty smell, visible fuzzy or discolored patches on walls, ceilings, or in bathrooms, and past or ongoing water damage, leaks, or high indoor humidity. Mold can also grow behind walls, under flooring, or inside HVAC systems where it isn’t immediately visible, so a musty odor without visible growth is still worth investigating.

If you had a roof leak, a slow plumbing leak, flooding, or a burst pipe in the last few days, mold can start developing quickly in the damp material left behind. See burst and frozen pipes and flood cleanup for what to do about the water itself, or read what water damage restoration involves to understand the drying process that keeps it from taking hold in the first place.

Is mold in the house dangerous?

The CDC states that mold can affect different people differently, and that some people, including infants, the elderly, and people with asthma, allergies, or weakened immune systems, may be more sensitive to it than others. The agency does not recommend routine testing, because sampling and culturing don’t reliably predict whether a specific person will get sick, and there’s no accepted standard for how much of any given type is “safe” in a home. The EPA’s mold cleanup guidance is consistent with this: whatever type is present, it should be removed, and the moisture problem that allowed it to grow needs to be fixed at the same time. If it is affecting your health, talk with a doctor; this page is general information, not medical advice.

What does professional mold remediation involve?

Mold remediation work generally follows a version of the process described in the EPA’s mold cleanup guidance and the industry’s ANSI/IICRC S520 Standard for Professional Mold Remediation:

• Find and fix the moisture source. Remediation without repairing the leak, humidity, or ventilation problem tends to fail, since growth returns on damp material.
• Contain the work area. On larger jobs, crews typically hang plastic sheeting to isolate the affected area from the rest of the home and run negative air pressure machines so spores don’t spread to clean rooms during the work.
• Remove contaminated material. Porous materials that have absorbed spores, such as soaked drywall, insulation, or carpet, are usually removed and discarded rather than cleaned, since growth can spread into the material itself.
• HEPA clean the space. The work area and any exit path are typically vacuumed with a HEPA air scrubber and wiped down, which captures spores that ordinary cleaning leaves behind.
• Dry the structure. Once contaminated material is out, the remaining structure is dried to a normal moisture level so it doesn’t return.
• Verify the work. On larger or insurance-involved jobs, a separate assessment (often by a different company, see below) can confirm the area is clean before it’s closed back up.

The EPA notes that small areas under about 10 square feet can sometimes be handled by a homeowner directly. Larger areas, contamination from a significant water event, or growth inside HVAC ductwork generally call for a professional with the right containment equipment.

Do you need a license for mold work in Texas?

Yes, in most cases. Texas regulates mold work through the Texas Department of Licensing and Regulation (TDLR), which issues separate licenses for mold assessors (who inspect a property and write a remediation protocol) and mold remediators (who perform the actual removal, cleaning, and treatment).

Two rules to know if you’re hiring for a larger job:

• The small-job exemption. TDLR’s own guidance states that small areas of growth, under 25 contiguous square feet, can be cleaned or removed by an owner or maintenance staff without a license. Above that size, licensing generally applies.
• The same-company rule. TDLR rules generally do not allow the same person or company to act as both the assessor and the remediator on the same project. The idea is that the assessor’s job (writing the protocol and later verifying the work) shouldn’t be handled by the same business doing the removal. There is a narrow exception for work performed by employees of a school district on that district’s own project.

If your job is larger than a small patch, ask any company you’re considering whether they hold an active TDLR license, and confirm whether they’re doing assessment, remediation, or both before you sign anything.

Why East Texas homes see mold problems

Mold needs moisture to grow, and it doesn’t take a flood to create it. Slow plumbing leaks, roof leaks, poor bathroom or kitchen ventilation, and humid crawl spaces are common year-round sources in this region. A home that had water damage from a storm, a burst pipe during a winter freeze, or a slow undetected leak is at higher risk if the drying wasn’t thorough. Homeowners looking into mold remediation in Tyler or mold removal in Longview usually describe the same pattern: a water event that never fully dried. If it followed a specific water event, it’s worth reading insurance and water damage to understand what coverage might apply.

What does mold remediation cost?

Cost depends heavily on the size of the affected area, whether contaminated material needs to be removed and replaced, and whether the moisture source itself (a roof, plumbing, or HVAC issue) also needs repair. National cost-guide data from HomeGuide gives a rough sense of scale:

Because pricing varies so much by scope and by local contractor, get a written, itemized estimate from the crew rather than relying on these national figures, and ask what’s included (assessment, containment, removal, drying, and any post-work verification). See our water damage cost guide for more on how restoration pricing generally works.

Does insurance cover mold remediation?

Insurance usually covers mold only when it results from a sudden, covered event like a burst pipe, and usually excludes mold from neglect, humidity or a long-running leak. The Texas Department of Insurance also notes that some water-related coverage, such as backup of sewers or drains, is often a separate optional endorsement rather than something included automatically in a standard policy. Review your specific policy or ask your agent how your situation is classified before assuming coverage either way.

What to do next

If you can see or smell mold, or you had recent water damage that wasn’t fully dried out, don’t wait. Small problems get more expensive the longer moisture sits.
