Visual inspection with moisture mapping
This is the core of most assessments. The assessor looks for growth, tests materials for moisture and traces the water's path. It answers where, how much and why, without a lab.

Mold Inspection
Mold Inspection: what it covers
Quick answer
A Texas mold inspection is done by a TDLR-licensed assessor who inspects, maps moisture and writes the plan, and is not the company that removes the mold. State law bars one license holder from doing both on the same project. Expect a visual inspection and moisture readings first, with air sampling optional rather than automatic.
If you smell mold or see a stain that keeps coming back, the first step is a look, not a lab kit. A visual inspection with a moisture meter finds more than most people expect, because mold needs water and the water leaves a trail. The question is where it came from and how far it spread.
In Texas, the person who looks is not allowed to be the person who removes. Texas Occupations Code Chapter 1958 says a license holder may not perform both mold assessment and mold remediation on the same project, and may not own an interest in both companies. The Texas Department of Licensing and Regulation, or TDLR, licenses both roles.
That rule works in your favor. The assessor's job is to tell you what is there, in writing, with no stake in how big the cleanup is. The remediator then works from that plan, and the assessor can check the result.

Warning signs
Signs you need mold inspection
Do not disturb, scrub or cut into a large patch of growth before the assessment, since that can spread spores and change what the assessor finds. Fix the water source if you can, and keep the HVAC fan off if growth is near a vent.
- A musty odor in a closet, bathroom or room that was wet
- Stains with a darker ring or a fuzzy edge on a ceiling or wall
- A leak that was dried more than a day or two after it began
- Paint or wallpaper that bubbles on a wall near a pipe or an attic heater
- Baseboards or cabinet bases that remain soft after a repair
- A room where allergy-like symptoms get worse and ease when you leave
- A ceiling below an air handler or condensate line that has been stained before
- A house you are buying or selling where a past leak is mentioned
Our process
How our mold inspection visit works
Interview and walk-through
The assessor asks about the leak history, the smell and when symptoms began. Then the home is walked, room by room, with attention to wet areas and the spaces around them.
Measure moisture and look behind surfaces
Moisture meters and a thermal camera show where materials are wet or have been. Access points such as attic hatches and cabinet backs are checked as well.
Sample only if there is a reason
Surface or air samples are optional and used when they answer a question the visual inspection cannot. They are not an automatic add-on.
Write the findings and the protocol
For a job of 25 contiguous square feet or more, the assessor writes a protocol the remediator must follow. You get a document that shows where growth is and what is to be removed.
Check the work afterward
The assessor reviews the finished work against the protocol before the area is closed up. The assessor and the remediator stay separate throughout.
Cost
How much does mold inspection cost in Lewisville?
Assessment is a flat fee in many cases, with lab work extra if you choose it. The remediator is a separate company and is priced separately, so ask for the two quotes in writing.
| Job | Typical range | What it includes |
|---|---|---|
| Mold inspection and assessment by a licensed assessor (visual and moisture mapping) | $150–$600 | A separate company from the remediator |
| Mold lab sample (per sample) | $75–$450 | Sources disagree; lab and sample type matter |
| Emergency inspection and moisture assessment | Free–$200 (often credited if work goes ahead) | A water-damage walk-through, not a mold assessment |
| Small mold remediation (under about 10 sq ft, contained) | $500–$1,500 | For context only; done by a different company |
| Moderate mold remediation (larger drywall or flooring area) | $1,500–$3,500 | For context only; priced from the assessor's plan |
Assessors set their own fees, so these figures are only a rough guide. Ask what is included before you book, and keep the assessor's cost and the remediator's cost separate in your budget.
Why does Texas separate the inspector from the remover?
Texas law, Occupations Code Chapter 1958, bars a license holder from doing both mold assessment and remediation on one project, and from owning an interest in both companies. The idea is that the scope should reflect what is actually in the house, not what a cleanup company would like to bill.
Think about how a one-stop offer would work. A company tests, finds a problem and prices the removal, all with the same incentive. Texas decided that split was worth requiring.
That is why a straight answer from any mold company here will include the other half: someone else writes the plan, or someone else carries it out. Both should be licensed by TDLR, and both should show their licenses on request.
Do you need air sampling to know if you have mold?
Not usually. A visual inspection and moisture mapping tell you where growth is and why, and air samples add little to that. They can help in a few cases, such as a hidden problem with no visible growth, and the assessor should explain the reason before you pay for any sampling.
Air test results depend on the day, the weather, whether doors were open and how the sample was taken. A number without context can be misread in either direction, which is why it should not stand alone.
If anyone pushes sampling as the first step, or links it to a fear-based pitch, ask what question it answers. A good assessor will give you a clear reason or skip it.
When is an inspection worth doing?
An inspection is worth doing when you see or smell growth, when water sat for more than a day or two, or when growth may cover 25 contiguous square feet or more. It also helps before a sale. A minor, dried-quickly leak on a hard surface usually does not need one.
The 25 square foot line matters because above it Texas requires a licensed remediator working to a protocol. If you cannot tell whether you are above or below it, the assessor can measure and write down the answer.
Buyers and sellers sometimes ask for an inspection for another reason. A seller who passes the property on must give the buyer every Certificate of Mold Damage Remediation issued in the preceding five years.
What happens after the assessor writes the plan?
You hire a licensed remediator to carry it out, and the remediator follows the plan's scope, containment and cleanup steps. The assessor can return to check the work. If the area is under 25 contiguous square feet, a license may not be needed, and you may handle or hire removal without a protocol.
The plan is yours, and you can show it to more than one remediator to compare quotes against the same scope. That makes bids easier to read than a stack of different descriptions.
Meanwhile, drying must continue. A protocol does not help if the wall behind it is still wet. The mold remediation page explains what removal involves.
What should you have ready before the assessor arrives?
Gather the dates and causes of any leaks, the drying records and photographs from earlier water jobs, repair invoices and any prior mold paperwork. Note where the smell is strongest and when symptoms began. The more history the assessor has, the faster the water's path can be traced and the plan written.
If a restoration crew dried the house after a leak, ask for the moisture log. It shows how fast materials dried and which areas lagged, and that points the assessor to the places most likely to have trouble.
Clear access to the attic, the closets on exterior walls and the cabinets under sinks. Move nothing that you suspect is wet. An assessor wants to see the problem where it is, not after it has been cleaned up.
Options
Types and options for mold inspection
Surface and bulk sampling
A sample from a visible patch can be sent to a lab to identify what it is. The result rarely changes the removal plan, which is why it is optional.
Air sampling
Air samples compare spore counts in different spaces. They vary with the day, the sampling method and the lab, so interpret them with care. They are never required to start a visual inspection or a drying plan.
Denton County
Why mold inspection is different in Denton County
Inspections in Denton County often start with a house that had a known water event: an attic water heater that dripped, a condensate line that overflowed in summer or a pipe that split. The assessor's first question is when the water came and how fast it was dried. The drying log from the earlier job helps answer that.
A tight, air-conditioned slab house can hide a slow leak behind a closet wall or inside a ceiling cavity. A thermal camera and meter often find it before any growth shows. The structural drying page covers the readings that explain why some leaks turn into mold and others do not.
Lewisville and the lake-area suburbs have a mix of older and newer houses, and the assessor can tell you how age affects what to look for. Older finishes may also contain asbestos or lead, which is a separate question for the EPA and the Texas Department of State Health Services before any demolition.
One call and it gets handled.
A crew is dispatched as fast as one is available, and you approve the estimate before any work starts.

FAQ
Mold Inspection FAQs
Does the water damage crew do mold inspections?
A water damage crew takes moisture readings and photographs as part of drying, which can help an assessor. A mold assessment is a separate service by a TDLR-licensed assessor who does not remove the mold.
How do I find a licensed assessor?
Use TDLR's license lookup on its website, and ask the assessor for a license number. Confirm that the company is not also the one that will remove the mold.
Can I skip the inspection and go straight to removal?
For areas under 25 contiguous square feet, a license may not be needed. At 25 or more, Texas expects a protocol from a licensed assessor first. If you are unsure how large the area is, an inspection answers it.
Is a mold test the same as an inspection?
No. A test is a sample sent to a lab, and an inspection is a person looking at the house, measuring moisture and finding the water. The inspection is the more useful of the two for most homes.
Is mold in my house dangerous?
Mold can trigger allergy and asthma symptoms in some people, and the CDC calls the term toxic mold inaccurate. If anyone in the house has health concerns, talk to a doctor as well as an assessor.
Will insurance pay for an assessment?
It depends on your policy and the cause of the water. Ask your agent before you hire anyone, and keep the written report, photographs and moisture readings in case they are needed.
