A mold inspection, called an assessment in Texas, finds where mold is, how much there is and why moisture reached it. A licensed assessor writes the findings and the remediation protocol. By Texas law the assessor cannot also do the removal on that project, so inspection and remediation always come from two separate companies.
After a leak, a flood or a ceiling that stayed wet for days, the question most people ask is whether there is mold. The honest answer is that you often cannot tell by looking. Growth can sit inside a wall cavity, above a ceiling or under flooring, and a clean-looking surface proves little about what is behind it.
An assessment is how you find out. In Texas, mold assessors are licensed by the Texas Department of Licensing and Regulation, or TDLR, and they work for you, not for whoever will do the cleanup. That independence is by design: the same license holder may not assess and remediate the same project, so the person telling you what is wrong has no cleanup contract riding on the answer.
This page is about the inspection role only. It does not offer removal, and no page on this site pairs testing with removal. If the assessor finds mold that needs to come out, the mold remediation page explains the other half, and it is a different company by law.
Do not cut into walls to look for mold, and do not run fans or a household vacuum across suspected growth, because that spreads spores. If the area is small and visible, stay out of it, keep children and anyone with asthma away, and wait for the assessment.
Assessment fees depend on the size of the house, how many areas are checked and how many samples are taken. The assessor and the remediator are separate companies on a project and are priced separately. These are working estimates, not a price list.
| Job | Typical range | What it includes |
|---|---|---|
| Mold inspection and assessment, visual plus moisture mapping | $250–$650 | Size of the home and number of areas drive the fee |
| Mold air or surface sample, lab fee per sample | $75–$175 | Samples are taken only when they help answer a question |
| Emergency inspection and moisture assessment for water damage | Free–$200 | A water-loss check, not a mold assessment; often credited if drying goes ahead |
| Small mold remediation, under 25 contiguous sq ft | $500–$2,000 | A separate company; shown for scale only |

The assessor inspects visually, uses meters and a thermal camera, and maps the moisture without taking samples. This is the usual starting point and often answers the main question, which is where the water went and whether materials are still wet.
When growth is suspected but not visible, or when you need a record for a sale or a claim, the assessor adds lab samples. Sample results are one input, not a verdict, and they are read in context.
After a larger remediation, the assessor returns to confirm the work matched the protocol. It is performed by the assessor, never by the remediation company that did the work.

No. Texas Occupations Code section 1958.155 says a license holder may not perform both mold assessment and mold remediation on the same project, and a person may not own an interest in both companies on the same project. The assessor inspects and writes the protocol; a separate remediator does the work.
The rule exists because an inspector who profits from cleanup has a reason to find more mold than there is. Texas adopted its licensing regime in 2003, and the conflict-of-interest rule is a central part of it. You may well have been offered a bundled test-and-remove package by a company elsewhere, and now you know why that is a red flag on a larger job.
For you, it means the person who tells you what is wrong is also the person who checks the work afterward, and neither of them is paid more if the job gets bigger. Ask any company you hire whether it also does remediation, and if so, whether it is working on your project.
Order one when a leak or flood stayed wet for more than a day or two, when a smell lingers, when you cannot see behind the damp materials, or when a claim or a home sale needs a record. The EPA's 24 to 48 hour drying guideline is not a deadline, and mold may have grown even if materials later dried.
The case for waiting to see is weak after a long wet period. Mold grows quietly in places you do not open, such as the top of a ceiling or the back of baseboards, and the cost of an assessment is small next to the cost of a repair that has to be reopened.
If a water-damage crew has already dried your house, ask for its moisture readings, the date it started and the dry reference it used. Those records give the assessor a head start. The page on structural drying explains what good documentation looks like, and the guide on mold after water damage in Texas walks through the order of steps.
Results tell you which kinds of mold spores were collected from the air or a surface at one place and time. They do not tell you the amount hidden in a wall or the health effects on you. An assessor reads them with the moisture map and the visual findings, not alone.
Air levels change with the weather, the HVAC and the time of day, and there is no single safe number to quote. Mold can trigger allergy and asthma symptoms in some people, and the CDC calls the idea of toxic mold inaccurate. A sample is evidence, not a diagnosis, and its value is in comparison with an outdoor sample and the visible findings.
That is also why a lab report alone is a weak basis for hiring a remediator. The protocol should say what to remove and why, and the clearance check should confirm it.
The assessor asks what got wet, when, for how long and how it was dried. This history shapes where the inspection looks, and it is why photos and moisture readings from the original water loss are worth keeping.
A visual inspection comes first, then moisture meters and thermal imaging map where materials are still damp. Moisture mapping often finds the source and the hidden extent that a stain does not show.
Air or surface samples may be taken and sent to a lab. Samples show what is present, not how much is behind a wall, so they are interpreted alongside the visual findings rather than on their own.
On a project of 25 contiguous square feet or more, the assessor writes a remediation protocol that a licensed remediation contractor follows. The report states the extent, the cause of the moisture and what must be removed or cleaned.
When removal is complete, the assessor checks that the area meets the protocol before it is closed up. On larger jobs the owner receives a certificate of mold damage remediation.
In Mansfield, the usual routes to hidden moisture are attic water heaters and air handlers, clogged AC condensate lines in a long cooling season, hail-damaged roofs and slab leaks. Each leaves damp insulation, drywall backs or baseboards that are easy to miss. The pages on ceiling water damage and slab leak water damage cover the water side.
Texas humidity slows drying, so an area that was wet in July or August may take longer to reach readings that match a dry reference. A good assessor compares the damp area with a reference reading from a part of the house that never got wet.
Ask any assessor for a TDLR license number and check it with TDLR. This site does not claim any TDLR license of its own. The agency also has a record of licensed assessors and remediators so you can see who is who before you sign anything.

The removal side of mold work, how Texas separates it from inspection, and what to ask for before anyone starts.
Air movers, dehumidifiers and moisture meters that dry the floors, wall cavities and ceilings water reached in Mansfield slab homes.
Stained, bulging or dripping ceilings: find the source above, relieve the water, dry the drywall and insulation, then repair.
Drying and cleanup for the flooring, baseboards and walls a leaking line under the slab has soaked.
For a slab home on the south side of the metroplex, our working estimates run about $1,200 to $4,000 for clean-water mitigation in one room or small area, $2,500 to $6,500 for gray water, and $7 to $15 per square foot for black water.
In Texas, mold assessment and mold remediation are licensed by TDLR and must be done by two different license holders on the same project.
Not always, but it is worth considering if materials stayed wet for more than a day or two, a smell lingers, or you cannot see behind the damp area. The EPA's 24 to 48 hour guideline is not a deadline. An assessor can confirm whether materials are dry and whether growth is present.
No. A water damage crew dries structures and takes moisture readings. A mold assessment is a separate licensed role in Texas, and the assessor cannot also do the removal. Keep the crew's readings and photos, because the assessor can use them.
As a working estimate, a visual and moisture assessment commonly runs $250 to $650, and each lab sample adds roughly $75 to $175. The exact price depends on the size of the house and how many areas are checked, and it is confirmed before the work begins.
It is the written plan the assessor prepares before removal on a project of 25 contiguous square feet or more. It states what to remove, how to contain it and what the clearance check will confirm. A licensed remediation contractor follows it.
It depends on the cause of the moisture and on your policy, and many policies limit mold coverage. Your insurer decides. Read the policy or ask your agent before you order, and keep the photos and records from the water loss.
A kit can show that spores exist, which is true of almost every home, but it cannot show where the moisture is or how much growth there is. For a damp area you cannot see into, a licensed assessor with a moisture meter is the more useful step.
