How testing calls are handled right now. Water Damage Pro Dallas does not test for mold and does not transfer testing calls yet. If you call about mold testing, the automated assistant writes down your name, phone number, address and what you need, as a message. Nobody promises a test will be set up, or how soon. Mold removal calls are different: those are transferred to an independent DFW mold remediation company.
Who does mold testing in Dallas
Mold testing in Dallas, and anywhere in Texas, is part of what the law calls mold assessment, and the Texas Department of Licensing and Regulation (TDLR) issues the licenses for it.
TDLR issues two assessment licenses to individuals: Mold Assessment Technician and Mold Assessment Consultant. The consultant is the one who writes a remediation protocol, the plan a remediator has to follow, and who checks the work at the end. Assessment firms hold their own company license, and TDLR separately licenses the laboratories that analyze mold samples.
The key rule: the person or firm that assesses a project cannot also remediate it. That keeps the tester from profiting on the size of the removal job the test points to. An owner sampling inside a home they own, does not need a license as long as the property has under 10 dwelling units.
Mold testing in Dallas homes: worth it or not?
EPA guidance puts it plainly: when growth is visible, sampling is usually not needed. Remove the mold and fix the water. Testing earns its fee in narrower situations.
Testing usually helps
- A musty smell with no visible growth, suggesting mold inside walls, under floors or in ductwork
- A leak was dried, and you want to know whether hidden materials grew mold
- After remediation, to confirm the area meets the protocol's clearance criteria
- A dispute with a landlord, seller or insurer where written findings matter
Testing usually adds little
- Mold is plainly visible and its size is obvious
- You only want to know whether it is "black mold" (the CDC says the type does not change how it should be handled)
- You hope a number will prove the house is "safe" (there are no federal limits for mold or spores)
- The water source is still leaking, so any result would change next week
What a mold assessment can include
Every job is different, so ask the assessor to put the planned scope in writing before the visit.
- Visual inspection. Walking the home, looking at stains, past leaks, the attic, closets, under sinks and the air handler.
- Moisture readings. A moisture meter, a handheld gauge for the water content of drywall, wood or flooring, points to spots still holding water, which often matters more than any sample.
- Sampling. Air samples pulled through a cassette by a pump, surface samples taken with tape or a swab, or a small piece of material sent to a lab.
- Lab analysis. Samples go to a mold analysis laboratory. TDLR licenses these labs; ask which one is used.
- Written report. Findings, the moisture source, the size of affected areas, and, if remediation is needed on a large area, a protocol for the remediator to follow.
Clearance testing after the mold is removed
Testing is not only something that happens first. On a licensed Texas job, the assessment consultant returns after the remediation contractor finishes for a post-remediation assessment. The area should show no visible mold or wood rot, the work should match the protocol and the contractor's work plan, and the results should pass the clearance standard the consultant set in writing before work began. The EPA also notes that surface sampling may be useful to check whether an area was adequately cleaned or remediated.
If the area fails, the remediator does more work as the consultant directs, and the area is checked again. If it passes, the remediation contractor gives you a Certificate of Mold Damage Remediation no later than 10 calendar days after the project ends. Both license holders sign it, and the consultant's part says the mold was remediated under the protocol and, when the consultant finds it so, that the underlying cause was corrected. Keep it. When you sell, Texas law says the buyer must receive copies of any certificates the house received during the five years before the sale.
Texas mold rules in short. Mold work in Texas is licensed by the Texas Department of Licensing and Regulation (TDLR). A small patch, under 25 contiguous square feet, usually falls outside the licensing rules. Bigger jobs generally bring in two separate license holders: a mold assessment consultant who writes the cleanup plan, called a protocol, and a mold remediation contractor who carries it out. Texas does not allow one license holder to play both roles on a single project. People who own a home or other residential property with fewer than 10 units are exempt when working on their own property. You can check any name on the TDLR license search; the Texas mold rules guide explains more.
Reading a mold test report without getting misled
A lab report full of spore counts can look alarming or reassuring, and neither reaction is always right. The EPA points out that there are no federal limits for mold or mold spores, so no number on the page can show that a house meets or fails a federal standard. That is why the EPA says sampling should be done by people with real experience designing sampling plans and interpreting the results.
Ask the assessor to walk you through the report in plain language. Good questions are where the moisture is, how large the affected area measured, which rooms were sampled and why, and what the results mean for the scope of any remediation. If the report finds 25 contiguous square feet or more that needs remediation, it should come with, or lead to, a written protocol. A report that names a problem but not its water source leaves the most important question unanswered.
Choosing a mold assessor in DFW
Because the line takes only a message for testing calls, many callers will find an assessor on their own. These questions apply to any of them:
- What is your TDLR license type and number, and your company's? Search both on the TDLR license search.
- Do you or your firm own any part of a remediation company, or get paid by one?
- How many samples, of what kind, and why those spots?
- Which licensed lab analyzes them?
- Will the report name the moisture source and measure the affected area?
- Should remediation be needed, who prepares the protocol and returns for clearance?
Each licensed assessor must give you the Consumer Mold Information Sheet before any mold-related work begins. Also know what TDLR does not do: it does not inspect or test homes for mold, and it cannot order a landlord to clean it up.
