TREC inspections only flag suspected mold, while TDLR assessments confirm causes—skipping one can leave hidden moisture issues and costly repairs uncovered.
A TREC-licensed home inspector may point out signs of mold or water damage. But they do not test, confirm, or fix the problem. Their job is to find problems that could be there. To know exactly what it is, you will need another licensed expert. Many people in Fort Worth only find this out after they have closed on the home.
TREC Flags Problems. TDLR Solves Them.
TREC (Texas Real Estate Commission) gives licenses to people who check homes. A home checker looks for things you can see are wrong. If you see a crack, write it down. If you smell something musty, make a note of it. If there is a stain you can see, put that in your report.
TDLR, or the Texas Department of Licensing and Regulation, gives licenses for mold assessors. You can find this under Texas Occupations Code. A mold assessor looks for what is causing the moisture. They write down their findings in a clear way. Then, they make a plan to fix the problem.
There are two types of licenses. Each one needs a different set of skills. Each license gives the person a separate legal right. Most home inspectors who have a TREC license do not hold a TDLR license. That is a completely different path.
Your buyer’s agent probably did not talk about this gap when the inspection report got to you. Most agents do not.
What Your TREC Inspector Is Legally Allowed to Do
A TREC professional can take a photo of a crack. They can say where it is and talk about any change in color or stains. As stated by the TREC Standards of Practice, the professional needs to say what they see. This is what they do.
But they cannot take a sample. They cannot look for wet spots. They cannot use a thermal imager. They also cannot say if the crack is letting water in now, or if it comes from old troubles. They do not have training for the job. And, Texas law does not let them do this work.
“Suspected mold” in a TREC report is like a warning sign. It does not say what the problem is. It tells you that you need to have someone else look at it. A lot of buyers read this and still buy the home. They finish the deal and move ahead. Then, after some months, they need to pay for the repairs because of the mold.
Fort Worth’s Clay Foundation Problem
Fort Worth is on Blackland Prairie clay. This soil gets bigger when wet and gets smaller when dry. Foundation engineering research says the soil in Fort Worth can move up or down by about 2 to 4 inches because of weather changes. This happens many times over the years. Each year, this can put a lot of pressure on concrete and can make cracks show up.
A crack in concrete lets water come in. When it rains and the soil is wet, water gets pulled to the crack. It moves through the crack, and can get to the framing above.
Your TREC inspector can let you know if there is a crack. They will not be able to say if water is moving through it at this time. They cannot find out the humidity inside the wall behind the crack. They also cannot say if the crack started two months ago or years before. The inspector cannot tell if water is coming in through the crack or if it is only a mark that does not let water in.
A TDLR-licensed person can help you answer all three questions. They will do this by using a moisture meter and a special camera that can show heat. They will also look at the area very closely. This is what makes a warning not the same as a full finding.
What Happens When You Skip the Assessment Before Closing
If you skip a good mold check before you buy, you can end up with big problems. You may miss a warning and then have to spend a lot of money on repairs. You might trust a report that isn’t right and does not help you if there is trouble. Serious mold can pop up months down the road, and you won’t be able to show it was there before you bought the place. In the end, you could have to pay thousands from your own pocket.
What a TDLR-Licensed Assessment Actually Documents
A Mold Assessment Consultant (MAC) comes with tools like moisture meters, heat cameras, and special rods. They walk around the foundation and look at how much water is in the air near the slab edges, walls, and under the house. They use heat cameras to find cool spots. These spots can show where water is leaving. They also take photos and collect samples from the area if needed.
They will make a report, and someone with a TDLR license will sign it. This signature proves that the report has legal standing in Texas. You can use it if you need to make a claim. You may show it to someone who wants to buy the place later. It is also useful when you talk about repair costs before closing.
The report gives some clear facts. A moisture measure at the edge of the slab, next to the east wall, showed 19 percent relative humidity. The usual reading there be 12 percent. Images that read heat show a cold spot at the bottom of the wall. This is the same place where moisture is moving in. A mark left by the water can be seen. This suggests that water got in during the last rain.
Your TREC inspector’s “suspected mold” note brings up a big question. The TDLR assessment gives the answer.
SB 1255: The License Change You Should Know About
In September 2025, Texas law changed how company licenses work. Now, with Senate Bill 1255, anyone who does a mold assessment has to have their own TDLR license. A company can no longer hire someone who does not have a license and let them do the work using the company’s license.
If you hire an assessor, ask them, “Do you have your own TDLR license?” You should talk to the person who comes to your place, not just the company. You must look at their ID or papers before they start. This will help you stay safe with the law.
The Assessment You Need Before, Not After, Closing
If the TREC home inspection shows there is any water problem, a crack, or something that could be mold, you should get a TDLR check before you close. Do not wait three weeks after you close. Do not wait three months, either. Get it done before.
The cost for this is usually between $500 and $800. The information you get is valuable. You will know if the home has a moisture problem now, or if it is just a stain from something that happened before. You can talk to the seller about fixing it. You can ask them to handle it before you finish the deal. You can also decide not to buy the home.
If you do not have the check before you close, you do not have all the facts.
FAQs
Can a TREC inspector also have a TDLR license?
Yes, but it does not happen often. The reason is that these two jobs do not cover the same work. Most people pick one and stay with it.
What if the report says “possible mold”?
Do not look away from this. A TDLR assessment can show if you have a problem and give you a legal report.
Do SB 1255 changes affect old assessments?
Yes. Older assessments may not be right now, so it is good to get a new one.
What if the seller says no to an assessment?
This is not good. It is best to ask for an assessment or leave.
**How much can it save?
** A $500 check can help you avoid $5,000 or more in repair costs.
The Gap That Costs You Thousands
A TREC inspector tells you about “suspected mold” before you buy the home. You go ahead and buy it. After you move in, you get someone to check the house. They find water coming in through a crack in the base. Water has been getting in for over a year. It will take $8,000 to fix this. Now, the problem is yours.
A TREC inspector spots what looks like mold. You then have a TDLR checkup before you buy. The person doing the checkup notes the same crack. He says water got in over one year. You ask the seller to drop the price by $8,000 or to give you money to fix it. You get $8,000 in your favor.
If you want to buy a home in Fort Worth and the inspection report shows water, cracks, or mold, schedule a TDLR assessment before closing. This check gives you the legal paper that tells you the real condition of the home you are about to get. If you do not have this, you are taking a big risk and may not know what you are paying for.
