Black Mold in Colleyville Homes: Facts, Myths, and When Size Demands a Licensed Remediator

Few phrases trigger panic in a homeowner faster than "black mold." If you have spotted a dark patch under a bathroom sink or behind baseboards in your Colleyville home, take a breath before you assume the worst. The truth about black mold is more measured than the headlines suggest, and the question that actually matters has nothing to do with color.

What "Black Mold" Really Is

The term usually refers to *Stachybotrys chartarum*, a greenish-black mold that grows on damp, cellulose-rich materials like drywall, ceiling tile, and wood. It is real, and it does appear in homes that have had persistent moisture problems. But "black mold" is not a precise scientific category. Plenty of harmless or common molds also look dark, and *Stachybotrys* itself can look slimy green-black rather than the dramatic charcoal smudge people picture.

What is firmly established: any indoor mold growing on a chronically wet surface signals a moisture problem that should be corrected, and disturbing mold can release spores you would rather not breathe. What gets exaggerated is the idea that one species is uniquely toxic and that its mere presence is a medical emergency. Major health bodies have walked back the most alarmist "toxic black mold" claims. Sensitive individuals, people with asthma, and those with weakened immune systems can react to mold exposure, which is a good reason to address it promptly and carefully, not a reason to panic.

Why Color Is the Wrong Thing to Measure

Here is the part most homeowners never hear: in Texas, the rules that govern mold cleanup do not care what color the mold is. They care about *how much* of it there is.

Mold remediation in Texas is regulated by the Texas Department of Licensing and Regulation (TDLR). Under TDLR rules, work involving mold over a certain size threshold must be performed by a licensed mold remediation contractor. There is, however, a recognized exemption for small areas: cleanup of mold affecting less than 25 contiguous square feet does not require a TDLR mold license. That 25-square-foot line, not the shade of the growth, is what determines who is legally allowed to do the work.

So a small green-black patch the size of a placemat behind a vanity may be a straightforward cleanup. A black-streaked ceiling spanning half a room, or mold hidden across a large wall cavity, is a licensed-remediator job regardless of how mild it looks. Scope decides scope.

What Go Green Restoration Can and Cannot Do

Go Green Restoration is bonded, insured, IICRC-certified, and EPA Lead-Safe certified. We are not a TDLR-licensed mold remediation company, and we do not present ourselves as one. What we handle is small-area mold cleanup under that 25-contiguous-square-foot exemption, paired with the moisture control that keeps it from coming back.

For those small jobs, our approach focuses on doing the work safely and getting to the actual cause:

• Containing the small affected area and cleaning mold from surfaces using careful, EPA Lead-Safe certified methods—important in older Colleyville homes where lead paint may be present
• Finding and correcting the moisture source, whether a slab leak from our shifting clay soils, a slow plumbing drip, or roof and flashing damage after a hail and wind storm
• Drying materials thoroughly so spores have nothing to feed on
• Advising you honestly when what we find exceeds the small-area threshold

If we open up a wall and discover the growth is larger or more widespread than 25 contiguous square feet, we stop and tell you. That work legally requires a TDLR-licensed mold remediation contractor, and we gladly refer you to one. We would rather hand off a job than overstep what we are certified to do.

Local Conditions That Feed Mold in Colleyville

The larger custom homes around Colleyville Heritage and Colleyville Heritage come with premium finishes that deserve careful handling, and they also have plenty of square footage for moisture to hide. Storm season is a recurring culprit: hail and wind that batter tile and slate roofs can open small leaks that go unnoticed until a ceiling stain appears. Our expansive clay soil is another, flexing with the seasons and causing slab leaks that quietly dampen flooring and lower walls.

The practical takeaway is to treat moisture as the enemy and color as a distraction. Fix leaks fast, keep an eye on areas under sinks and along exterior walls, and act on small spots before they spread past the point where a simple cleanup is even allowed.

If you have found a small patch of suspected mold in your Colleyville home and want an honest assessment of its size and cause, call Go Green Restoration at (469) 727-3217.
