Small-Area Mold Cleanup in Mansfield, TX: Understanding the 25 Square Foot TDLR Rule

If you have found a patch of mold under a bathroom sink or behind a baseboard in your Mansfield home, your first question is probably simple: can someone just come clean it up, or is this a bigger deal? In Texas, the answer hinges on a specific number written into state regulation. Understanding that number puts you in control of the decision and helps you avoid both overpaying and underestimating a problem.

The 25-Square-Foot Line That Texas Draws

Texas regulates mold remediation through the Texas Department of Licensing and Regulation (TDLR). The rules require a licensed mold remediation contractor for projects involving mold that affects 25 or more contiguous square feet. The word "contiguous" matters: it means a single connected area, not the total of small spots scattered around your house.

Below that 25-square-foot threshold, the work falls under a TDLR exemption. That means a non-licensed but qualified professional can legally clean up the affected area. Go Green Restoration is bonded, insured, IICRC-trained, and EPA Lead-Safe certified, and we handle exactly this kind of small-area cleanup. What we do not do, and cannot legally do, is full mold remediation on larger jobs. We are not a TDLR-licensed mold remediation company, so anything at or above 25 contiguous square feet goes to a licensed remediator. We are glad to refer you to one.

How to Tell Which Situation You Have

Measuring contiguous square footage is easier than it sounds. Picture the visible mold as a rectangle and estimate its width times its height. A spot the size of a sheet of paper is well under one square foot. A patch covering most of a 4-by-8 sheet of drywall is approaching the threshold and may cross it.

Use these quick guidelines as you assess what you are looking at:

• **Likely small-area cleanup:** a single patch smaller than roughly a 5-by-5-foot square, on a hard or semi-porous surface, with a clear and recently fixed moisture source.
• **Likely needs a licensed remediator:** mold spreading behind walls, across a ceiling, through an HVAC system, or covering a large connected section of drywall; visible growth larger than 25 contiguous square feet; or musty odors with no visible source.

When mold is hidden inside a wall cavity, the visible patch is often only part of the story. In Mansfield, this comes up frequently because of our expansive clay soil. Foundation movement can crack supply lines and drains, and a slow hidden plumbing leak can feed mold inside a wall long before you see a stain. If the moisture source is hidden or the growth disappears behind a surface you cannot see past, treat it as a job for a licensed professional rather than a quick cleanup.

Why Small Jobs Still Deserve a Careful Approach

Even a cleanup under 25 square feet should be done correctly, not just wiped away. Mold returns whenever the moisture that fed it returns. That is why our small-area work centers on two things: removing the affected material safely and controlling the underlying moisture so it does not come back.

Many homes around Historic Downtown Mansfield and newer subdivisions near Walnut Creek were built in the last 15 to 20 years with builder-grade materials. A small roof or window leak after a spring hailstorm can let water into a wall, and weeks later a tenant or homeowner finds a contained patch of mold near a window frame or ceiling corner. For a genuinely small, contained spot like that, careful cleanup paired with fixing the leak is often all that is needed.

Our EPA Lead-Safe certification matters here too. Homes and additions can contain lead-based materials, and disturbing a moldy surface without proper containment can spread both mold spores and lead dust. Lead-Safe methods mean we contain the work area, control dust, and clean up thoroughly so the cleanup itself does not create a new problem.

When in Doubt, Get Eyes on It

The honest reality is that some mold situations look small on the surface and turn out to be large once a professional investigates the moisture source. There is no shame in calling for an assessment before deciding. We will tell you straight whether your situation fits within the small-area exemption we can address, or whether it has crossed into territory that requires a TDLR-licensed remediator, and we will help you find one if it has.
