Mold Inspection in Austin, TX

In Texas the person who inspects for mold is a licensed mold assessment consultant, licensed by TDLR. The visit is built around one question: where is the moisture coming from? Mold is the symptom. A protocol that removes growth without naming the source sends you back to square one after the next storm.

What gets checked, by type of Austin house

Pier-and-beam homes in the central neighborhoods. The assessor goes under the house with a flashlight and a moisture meter, checking joists, the underside of the subfloor, insulation, drain lines, and whether the soil stays wet after rain. A musty smell in a Hyde Park or Travis Heights living room very often starts down there.

Slab homes with attic air handlers. Up top, the focus is the condensate pan and line, sweating ductwork, the roof deck around vents, and ceiling drywall below the equipment. Inside, walls around tubs, water heaters, and kitchen sinks get readings, because foundation movement and age can strain the plumbing that runs under and through a slab.

Homes near Onion Creek, Williamson Creek, and other flood-prone creeks. Lower walls, baseboards, carpet tack strips, and the bottom of cabinets are where old floodwater leaves damage that paint can hide.

When an inspection is worth booking

• Water got inside after a storm or a burst pipe and was not dried within 24 to 48 hours, the window the EPA recommends.
• A musty smell keeps coming back and there is no visible growth.
• You are buying an older home. About 28% of Austin's housing was built before 1980, according to the Census ACS, and many of those homes are pier-and-beam.
• You see growth that looks larger than about 25 square feet, which is the point where Texas requires licensed professionals.

A small spot on a bathroom ceiling with an obvious cause usually does not need an inspection. Fix the moisture and clean it; the EPA considers patches under about 10 square feet a homeowner job.

The protocol: what you should get on paper

If cleanup is needed, the consultant writes a remediation protocol. It should list the rooms and approximate quantities of material to remove, the cleaning methods, the containment and protective equipment the crew must use, and the clearance criteria the job has to meet at the end. Contractors bid against that document, which is what makes their quotes comparable.

Why the inspector will not do the removal

Texas does not allow one license holder to perform both the assessment and the remediation on the same project. The consultant who measures your problem therefore has no financial interest in making it bigger. It also means you will deal with two companies; the one you reach by phone can explain who does what.

Austin inspection prices

Local price guides published in 2026 put a visual inspection at about $200 to $600 and an inspection with air sampling at about $300 to $800. Crawl space access, a large attic, and extra samples raise the price. Offers of a free inspection usually mean a visual look without samples or a written protocol; our guide to free mold inspections explains the trade-offs. If you only need lab samples or a clearance check, see mold testing in Austin; if the problem is already mapped, go to mold remediation in Austin.

Making the call

Have three things ready: whether the house is pier-and-beam or slab, when the water problem started, and where you smell or see mold. The company you are connected with can then quote the visit and tell you whether samples are likely to be needed. The call is free and you decide whether to book.

Texas licenses mold assessment consultants through TDLR, with limited exemptions such as owners working on their own small residential property. Look up the Austin consultant at tdlr.texas.gov before the visit; the same license holder may not also do the removal on your project.
