Mold after water damage is the problem fast drying is meant to prevent, but it still happens when a slow leak goes unnoticed or a wet wall gets closed up too soon. Texas regulates mold work more than most states. Under the Texas Mold Assessment and Remediation rules, mold remediation of 25 contiguous square feet or more generally must be done by a mold remediation contractor licensed by the Texas Department of Licensing and Regulation (TDLR), working from a protocol written by a separately licensed mold assessor. Elm Fork Water Restoration doesn't do mold remediation. For mold jobs that size, we refer you to a TDLR-licensed mold remediation company.

Under 25 square feet vs. 25 or more

Situation	Usually
A few spots on a bathroom ceiling or a small patch behind a sink, well under 25 sq ft	Can be cleaned by a homeowner or a general water damage crew, once the moisture is fixed
Mold covering 25+ contiguous sq ft, about a 5 ft × 5 ft area	TDLR-licensed assessor writes a protocol; licensed remediator does the work; assessor confirms it passed
Mold found partway through a water damage job	Work in that area should stop so it can be assessed; larger growth goes to a licensed remediator

The rules have exemptions (for example, some owners working on their own home). Check the details on the TDLR mold program site, and verify any company's license with TDLR's license search before hiring.

Signs of mold after a leak

A musty, earthy smell, especially when the AC kicks on or a cabinet is opened.
Gray, green or black spots on drywall, baseboards, the back of cabinets or under carpet.
Paint bubbling, peeling or staining in an area that got wet before.
Allergy-like symptoms that are worse at home.

Why the moisture comes first

Mold needs moisture to grow. Cleaning or treating mold without fixing the leak and drying the materials just resets the clock. That's why an assessor's protocol, and any good remediation, starts with the water source and ends with moisture readings, not just a clean surface.

Avoiding mold after water damage

Start drying within 24 to 48 hours.
Don't reinstall baseboards, flooring or cabinets until materials read dry.
Replace wet insulation and carpet pad rather than drying them in place.
Keep indoor humidity under about 50 percent while the house recovers.

Common questions

Do I need a licensed company to remove mold in Texas?

For mold covering 25 contiguous square feet or more, Texas generally requires a TDLR-licensed mold remediation contractor and a protocol from a licensed mold assessor, with some exemptions. Smaller areas don't require a license.

Can the same company test and remove the mold?

Texas rules generally don't allow the same company to do both the assessment and the remediation on the same project. That separation protects you from a conflict of interest.

Is black mold more dangerous?

Color doesn't tell you the species or the risk. Any significant mold growth indoors should be dealt with, and people with asthma, allergies or weak immune systems should avoid exposure.

Will bleach kill mold on drywall?

Bleach can lighten mold on hard surfaces, but on porous drywall it doesn't reach growth inside the material. Moldy drywall is usually cut out and replaced.
