Small-Area Mold Cleanup in Southlake: Understanding the Texas 25-Square-Foot Rule

If you have found a patch of mold under a Southlake sink or behind a baseboard, your first question is usually "how serious is this?" The answer in Texas often comes down to a single number: 25 contiguous square feet. That threshold determines whether a small-area cleanup is enough or whether your situation legally requires a licensed mold remediation contractor. Here is what that rule means in plain English and how to tell which category you fall into.

What the Texas 25-Square-Foot Rule Actually Means

In Texas, mold remediation is regulated by the Texas Department of Licensing and Regulation, or TDLR. State rules require that most mold remediation projects be performed by a TDLR-licensed mold remediation contractor. But there is a built-in exemption: when the affected area is less than 25 contiguous square feet, that work falls outside the licensing requirement and can be handled as a standard cleanup.

"Contiguous" is the word that trips people up. It means the mold has to be connected as one continuous patch. A single growth roughly five feet by five feet equals 25 square feet, so anything smaller than that connected area qualifies as small-area cleanup. If you have several small, separate spots in different rooms, they are generally measured individually rather than added together. The rule is about how large any one connected area of growth is, not the total across your whole home.

Go Green Restoration is not a licensed mold remediation company, and we do not present ourselves as one. We legally handle small-area cleanup under that 25-contiguous-square-foot exemption. Anything larger, or mold that has spread widely, requires a TDLR-licensed remediator, and we are glad to refer you to one.

What Small-Area Cleanup We Can Handle

When the growth is contained and under the threshold, the work is straightforward and we can take care of it as part of restoring the affected area. Our approach centers on EPA Lead-Safe certified methods and moisture control, because mold is almost always a symptom of a water problem that has to be solved or it simply comes back.

For a qualifying small-area cleanup, that typically includes:

• Cleaning visible surface mold from a contained spot under 25 contiguous square feet
• Finding and correcting the moisture source feeding the growth, such as a slow supply-line leak or condensation around a fitting
• Removing and replacing small sections of saturated drywall, trim, or cabinet material
• Drying the structure thoroughly so humidity does not invite a second round

In many Southlake homes around Carillon or Timarron, the larger footprints and custom layouts mean more plumbing runs and more fittings, which translates to more places a small leak can start quietly under a vanity or behind a built-in. Catching one of those early often keeps the problem comfortably inside small-area territory.

How to Tell Which One You Have

You will not always be able to eyeball this accurately, and that is fine. Here are the practical signs that point toward a larger project that needs a licensed remediator rather than a cleanup. If mold covers a connected area bigger than a five-by-five-foot square, that is over the line. If you pull back drywall or peek behind a cabinet and find the growth runs well past what was visible, the hidden area counts too. Mold inside your HVAC system is another flag, and Southlake's larger custom HVAC setups can carry spores between rooms before you ever see a spot, which tends to push a problem beyond a simple contained patch.

Water history matters as well. A long-running roof leak from a spring hail storm, the kind that damages roofing and skylights across Tarrant County every year, can soak insulation and framing for weeks before staining appears on a ceiling. By the time you notice, the affected area is frequently much larger than the visible mark suggests. Those are exactly the situations where a TDLR-licensed mold remediation contractor should take the lead, and we will help you find one.

When we come out, we assess the contained area honestly. If it qualifies as small-area cleanup under the exemption, we handle it and address the moisture behind it. If it is larger or more widespread than the rule allows, we tell you plainly and refer you to a licensed remediator. We never stretch a job past what we are legally able to do, and we never tell a homeowner a serious mold problem is smaller than it is.
