Mold Inspection and Testing in San Antonio, TX

Texas splits mold work into separate licenses: assessment technicians and consultants, who inspect, sample and write protocols, and remediation contractors, who remove (TDLR). A license holder may not do both on the same project, and nobody may own both companies on one project (Texas Occupations Code 1958.155). That separation is the point: the person telling you how much mold you have doesn't profit from the answer.

In Texas the assessor is built into any licensed job. For contamination of 25 contiguous square feet or more, a licensed assessment consultant writes the remediation protocol before work starts and carries out the clearance inspection after it, and their statement goes on your Certificate of Mold Damage Remediation (1958.154). If you can already see a large patch, you need both: see mold remediation in San Antonio. You need an assessor on their own when the question is whether, where or how much, or when you need an independent report. Check any license on the TDLR license search.

The EPA is direct: "In most cases, if visible mold growth is present, sampling is unnecessary" (EPA). The CDC doesn't recommend mold testing and says you don't need to know the type to clean it up (CDC). Paying for a test to confirm that the black patch on the wall is mold is money better spent on removing it.

Testing earns its keep in specific situations, which the EPA's own guidance lists (EPA):

• The source is unclear. A musty smell, allergy symptoms that ease when you leave the house, or a stain with no obvious leak. An assessor finds the moisture and the growth, often behind drywall, in the attic or in the air handler.
• Health concerns. Someone in the home with asthma, allergies or a weakened immune system, and you need to know what you're dealing with.
• A licensed remediation. In Texas, jobs of 25 contiguous square feet or more need an assessor's protocol first and a clearance inspection after.
• Buying, selling, renting or a dispute. A landlord, buyer, seller or insurer wants an independent written finding. In San Antonio that is often an older home changing hands, a rental turning over, or a house that flooded from a creek.

Texas law defines assessment as an inspection, investigation or survey of a structure to tell the owner about the presence, identification or evaluation of mold; the development of a mold management plan or remediation protocol; and the collection or analysis of samples (Texas Occupations Code 1958.001). The rules say the purpose is to determine the source, location and extent of growth, and that samples follow nationally accepted methods with a chain of custody and go to a licensed laboratory (16 TAC 78.100). In practice a visit looks like this:

1. Interview and history. Past leaks, floods, freezes, AC problems, when the smell started.
2. Visual inspection. Every room, closets, the attic, the air handler, under sinks.
3. Moisture and thermal readings. A moisture meter and an infrared camera find wet materials behind finishes (see what a normal moisture meter reading is).
4. Sampling, if warranted. Air samples indoors compared with outdoors, and surface swabs or tape lifts, sent to a licensed lab.
5. Report and protocol. Findings, photos, lab results and the likely moisture source. For a licensed remediation, the protocol specifies the quantities and locations of materials to be removed, the methods for each area, the protective equipment, and the criteria the job must meet to pass clearance.

Published national figures put a mold inspection at roughly $300 to $1,000, with averages around $500 to $650, and testing at about $50 to $700 depending on how many samples go to the lab (Fixr, 2025; Bob Vila). In Texas, the protocol and the clearance inspection for a licensed remediation are usually priced as separate items. San Antonio rates sit around the middle of those ranges. Ask what the fee includes (number of samples, lab fees, the written report, the clearance visit) before booking.

In Texas, clearance isn't optional on a licensed job. A licensed mold assessment consultant conducts a post-remediation assessment in each remediated area, with a visual, procedural and analytical evaluation, while any walk-in containment is still in place; the area must be free of visible mold and wood rot and the work done to the protocol before a passed clearance report is issued (16 TAC 78.140). Within 10 days the remediator then gives you the Certificate of Mold Damage Remediation, carrying the assessor's statement, plus before-and-after photos (16 TAC 78.150; TDLR FAQ).

The EPA's plain-language test for "finished" is the same everywhere: the water problem is fixed, no visible mold or moldy odors remain, and people can use the space without symptoms (EPA).

• A musty smell you can't trace, or symptoms that improve away from home
• Water damage you suspect wasn't fully dried (a past flood, a burst pipe in the freeze, a previous owner's repair)
• Before buying, or after remediating, a property
• A dispute with a landlord, tenant, seller or insurer

Call (726) 224-4911 and we'll connect you with a local assessor. If you can already see a sizeable patch, go to mold remediation; if it's wet, start with water damage restoration.
