Mold Testing in DeSoto, TX: What to Do and Who to Call

Do You Really Need Mold Testing?
Often, no. The EPA says sampling is unnecessary in most cases when visible mold is present. The Texas Department of Licensing and Regulation (TDLR) says you do not need to know the mold type before cleanup. First, find and fix the water.
Testing for mold can still help. It can show if a stain is mold or dirt, point to hidden growth, or give a licensed assessor what is needed to write a cleanup plan.
Know the limits. An air sample shows one moment only. The EPA says a negative result never replaces a visual check. No federal limit exists for mold, so a test cannot pass or fail a home.
What usually brings people here
- A musty smell that returns after a storm or a leak
- A stain on a ceiling, wall or under a sink
- A buyer, seller, landlord or insurer asking for proof
- A kit result that scared you and explained little
- Worry that the tester will also sell you the cleanup
Is Mold Dangerous, and Can You Stay Home?
Spores are everywhere, indoors and out, and people react in different ways. TDLR and the CDC say sample results cannot show your own health risk. A spore count is not a health result.
Worried about symptoms? Ask a doctor. A licensed assessor can inspect the home itself.
Why Mold Shows Up in DeSoto Homes
Mold needs moisture. The National Weather Service calls the Dallas Fort Worth climate humid subtropical, with hot summers. These are common moisture sources here.
- Spring storms. Heavy rain, wind and hail can open a roof. Hail falls on about two or three days a year in the metro area.
- Roof and pipe leaks. TDLR lists these first among common moisture problems, with floodwater and sewage backups.
- Humid summers. Warm, damp air can leave moisture on cool surfaces, including air conditioner ducts.
- Overflowing tubs, sinks and toilets. TDLR names these too.
Can You Test for Mold Yourself in Texas?
Yes, at your own home. TDLR says owners of residential buildings with fewer than 10 units do not need a license to assess or clean mold on their own property. Visible mold under 25 contiguous square feet can usually be cleaned by unlicensed people.
The limits: results need an inspection to be read, and a home test cannot produce a protocol or certificate.
| Task | Owner, fewer than 10 units | Licensed professional |
|---|---|---|
| Look for mold and leaks | Yes | Not required |
| Clean under 25 square feet | Usually yes | Not required |
| Take your own samples | Allowed | Required for a protocol, clearance or certificate |
| Write a protocol, sign a certificate | No | Yes |
Safe steps for small areas
- Fix the moisture first.
- Clean hard surfaces such as tile, metal and glass.
- Throw away soaked drywall, carpet and insulation.
Two myths
- Bleach or paint fixes mold. TDLR says neither is a permanent fix.
- You must test first. The EPA says sampling is unnecessary in most cases when mold is visible.
- You cannot find the water source.
- You need a protocol, clearance or certificate for insurance or a sale.
- Someone at home has health worries. Ask a doctor first.
What Texas Law Says About Testing for Mold
TDLR regulates this work under Texas Occupations Code Chapter 1958 and 16 Texas Administrative Code Chapter 78.
- People and companies that inspect and sample for mold must hold a TDLR license unless exempt.
- A licensed consultant writes the cleanup protocol: where, how much, which methods, and the cleanup goals.
- A licensed contractor follows the protocol. The consultant then checks the work.
- One license holder may not do both assessment and cleanup on the same project.
- TDLR does not inspect or test homes, and it cannot make an owner or landlord do so.
- TDLR readopted these rules in March 2026 after its required four year review.
Check any license on the TDLR license search. The TDLR consumer sheet explains your rights in plain words.
How Professional Mold Testing Works
- Inspection. The assessor checks the home and looks for the water source.
- Sampling plan. The assessor sets how results will be read before work starts.
- Samples. A mold air test takes air. Surface samples come from one spot.
- Lab. Samples go to a lab. Texas licenses mold analysis labs.
- Report. You receive written findings.
- Protocol. If cleanup is needed, the assessor writes the plan.
- Clearance. After cleanup, the assessor checks the work. The contractor and assessor then sign the Certificate of Mold Damage Remediation.
Air or surface samples?
Air samples show what floated by at that moment. Swabs and tape lifts check a stain or a spot. Neither shows the whole home, so the inspection guides the choice.
Why an outdoor sample?
Spores drift in from outside. Assessors often compare indoor samples with an outdoor one. The EPA uses the same idea after cleanup: indoor spore types and amounts should be similar to outdoors.
How long do results take?
It depends on the home, the number of samples and the lab. Ask the provider for the schedule in writing.
Where testing stops: It does not remove mold or fix leaks. A separate licensed contractor cleans. A plumber or roofer fixes the water source.
Licensed Testing vs Home Test Kits
If you search for mold testing near me, check the license first.
| Home kit | Licensed assessor | |
|---|---|---|
| Sampling plan | None | Set before testing |
| Reading results | Hard without an inspection | Tied to the inspection |
| Protocol | Not possible | Written by a consultant |
| Certificate | Not possible | Possible with a licensed contractor |
Is an ERMI test worth it?
No. The EPA says its ERMI score is a research tool and is not recommended for any other use. See the EPA mold questions page.
What Does Testing Cost, and Does Insurance Pay?
We do not quote prices. Each independent provider sets its own. These things change the price:
- Home size and layout
- Number and type of samples
- Lab fees
- A written report or protocol
- Attics and crawl spaces
- The reason: a sale, a claim or a worry
Ask every provider for
- Its TDLR license number
- A written scope
- What lab fees and the report cover
- Whether the protocol and re-testing are included
Does insurance pay?
It depends on your policy and the cause of damage. The Texas Attorney General says residential policies do not cover all water and mold damage. Call your insurer first.
The Texas Department of Insurance (TDI) regulates insurers. Its mold certificate form tells owners to give a copy to their insurer. TDI rules limit how insurers use past mold damage when a property was remediated and certified.

Questions About Testing for Mold
What does testing for mold cost?
It depends on home size, sample count, lab fees and whether you need a protocol. Each independent provider sets its own price. Ask for a written scope.
Does insurance pay for a mold test?
It depends on your policy and the cause of damage. The Texas Attorney General says residential policies do not cover all mold damage. Call your insurer first.
Do mold test kits work?
Not well. Spores are everywhere, so a kit can show mold in almost any home. Kits skip the inspection, and TDLR says results cannot be read without one.
Can I test for mold myself in Texas?
Yes, at your own home. TDLR exempts owners of residential buildings with fewer than 10 units. A home test cannot create a protocol or certificate. For those, you need a TDLR licensed professional.
Is testing needed if I can see mold?
Usually not. The EPA says sampling is unnecessary in most cases when visible mold is present. This includes black mold, since TDLR says knowing the type is not required before cleanup. Find and fix the water source first.
How is testing done?
A licensed assessor inspects, sets a sampling plan, takes air or surface samples and sends them to a lab. If cleanup is needed, the assessor writes a protocol for a separate licensed contractor.
What is the difference between air and surface samples?
An air sample shows the air at one moment. A surface sample checks one spot. Neither shows the whole home, so the inspection decides which to use.
Can a mold test show if I am sick or if my home is safe?
No. TDLR and the CDC say samples cannot show your health risk. The EPA says no federal limits exist for mold, and TDLR says no safe level standard exists. Ask a doctor about symptoms.
Can the same company test and clean my mold?
Not on one project in Texas. A license holder may not do both assessment and cleanup, and may not own a stake in both. Check licenses with TDLR.
