Quick Answer: Mold inspections (meaning no testing just looking for mold) in Austin typically range from $300 to $900. Testing is more money depending on the type and quantity of testing required. Air sampling, swab sampling, ERMI testing, HVAC inspections, protocol and PRV testing can significantly affect the total cost. Below, we'll break down what each service includes and when paying more is actually worth it.
These are market ranges for individual mold testing services in Austin, not any single company's pricing, but what the market generally charges.
Cost — $300–$900
No lab testing involved. Identifies visible mold and moisture signs. In some states this is offered cheap or even free as a lead for remediation sales (that business model is not legal in Texas where testing and remediation companies are required to be separate). This is usually not sufficient in most case where mold is suspected because laboratory testing is likely necessary to confirm the findings. Some companies will prepare a report with their findings for you post-assessment to summarize what they have found. The price will vary depending on square footage mostly as a larger home will take longer to inspect than a small home. Additional requests to inspect crawlspaces, attics, etc will also add to the time on site and increase the cost.
Cost - $80–$150 per sample
Captures airborne spores in one room at one moment in time. A starting data point, but rarely sufficient on its own to draw meaningful conclusions about a whole home. An outdoor sample is always required so budget for a minimum of 2 mold air tests. Some inspectors rarely use air tests and others love them and perform a significant quantity of tests. Ask your mold assessor if any tests are already included in their price and how much it is to add on more tests. Also enquire about their testing strategy. There are certain companies with reputations for taking a huge amount of air samples and then using high-pressure sales tactics to add on many thousands to the price you already agreed too. Sometimes more tests are necessary IF there is strategy and a reason to take those tests. Also, some companies will charge less for their mold inspection price but have a heftier fee for the air samples, so it is important to be able to price compare apples to apples.

Cost— $80–$150 per swab
Identifies the species on a visible surface. Most useful when you can already see suspected mold and want to confirm what it is before remediation. This is when you see something that you think is mold, a swab that is similar to a Q-Tip can wipe the suspected mold and the sample will be sent to a laboratory for analysis.
Cost— $250–$600
DNA-based analysis of aged settled dust. Lab fees make this more expensive than a single air test, but it captures mold across a longer time window and catches heavier species that air tests consistently miss. A useful tool for certain situations, but expensive compared to other testing methods. Unfortunately, a lot of analysis and knowledge is needed to intrepret the results. So while a DIY option is available, usually the homeowner does not know the proper way to collect the dust and then is left with results that they cannot interpret.
ERMI results consultation — $90–$249 per session
These are usually not offered by mold inspectors as they already include these results in their reports, but by mold experts online who typically sell you a diy dust test and offer you a meeting to review the findings.

Cost— $500–$800
Goes beyond mold to measure particulates, VOCs, CO2, PM2.5 and other airborne factors. Relevant for chronic health concerns when mold is not the only suspected cause of concern. Sometimes when someone has health symptoms at home they suspect mold but in certain situations it is caused by other invisible pollutants. Performing indoor air quality testing lets us go room by room with equipment to test the air for a number of different things. For instance we can find out if someone is always tired because the carbon dioxide is really high in their bedroom or perhaps having a lot of allergy symptoms due to a lot of dust or headaches from VOCs. It is another useful tool that can help differentiate the rooms in the house to get to the bottom of a home health mystery.

A protocol is the plan for the remediation prepared by the Mold Assessment Consultant aka MAC (licensed in Texas by TDLR) for the Mold Remediator (also licensed by the TDLR). Some mold assessors are only certified as a Mold Assessment Technician aka MAT and they cannot legally prepare the protocol. So you may need to hire another company if your mold assessor is not a licensed MAC. The protocol is meant to protect the home owner from the remediation company doing too much work in the home (meaning ripping out too many walls and floors). The MAC sets out the scope of the job, how it is done, where it is done, how to clean, etc. It can be very high level or very detailed. This protects the homeowner to ensure the right work is being done in the right away. A reputable remediation company will want a proper protocol to follow.
After remediation is completed then the MAC comes back to perform Post-Remediation Testing. This is meant to provide comfort that the mold is gone and the air is safe for the homeowner and re-construction can begin. This testing MUST happen while containment is still up (the plasticy wall barriers you may have seen in photos). This way the MAC can test the air inside the containment area and compare it to the air outside the containment area. They also will test the outdoor air as a control test as well to see what the air is reading at outside the home. Depending on how many areas of the home were remediated, this can add up to quite a few tests at $85-$150 but it is an important step in the process to ensure that the remediation was successful.
These can be anywhere from $300 each to $1500 each depending on who is preparing these documents (quality & depth can vary greatly just ask any mold remediator who has to follow these plans!). A one room small mold issue is going to be a smaller protocol and less laboratory testing than a home with multiple mold issues in different rooms of the room. If the price is too cheap to cost at least 3 air samples and a site visit, you will want to question if you are getting a proper licensed and insured service.
A common misconception is that mold inspection cost is mostly about the inspector's time on site. However a portion of what you pay goes toward lab fees and testing materials. Each air cassette sample has a cost. An ERMI dust test sent to a qualified DNA lab costs several hundred dollars on its own. Swab samples go to an accredited lab for analysis. The more thorough the testing, the more samples are collected, and the more lab costs accumulate, before an inspector has even spent time reviewing results or writing a report.
Beyond lab costs, pricing is affected by the size and complexity of the home, whether the inspection covers exterior areas, whether extra areas like HVAC and ductwork are examined, the number of rooms tested, and whether indoor air quality testing beyond mold is part of the scope. A single-story home with no forced air equipment and a 3,500 square foot two-story home with an aging HVAC system and an accessible crawlspace are different jobs requiring different amounts of time and materials.
Here is a list of some reasons the price will vary:
In many states, mold remediation companies offer free or very cheap inspections to get in the door. The inspection is not really an independent assessment, it is a sales call. The same company that tests your home also profits from the cleanup, so there is a built-in incentive to find mold and recommend their own remediation services.
In Texas, that model is against the law. Texas state law prohibits the same company from both assessing and remediating mold. Mold assessors and mold remediators must hold separate TDLR licenses, Because there is no remediation revenue to subsidize a free inspection, Texas-licensed mold assessors charge appropriately for their time, testing materials, and lab fees. That is actually the system working correctly as it means the person testing your home has no financial stake in what they find. They are paid to give you accurate information about what is happening in your home and potentially prepare the protocol for the remediator to follow. Beware there are some companies that hold both licenses and present to you that they are independent but actually passing the remediation work to their other entity. Eg. Company A owned by the husband is the mold assessment company and Company B is the mold remediation company owned by the wife. And Company A always recommends that Company B does the remediation.
If you encounter someone in Texas offering a free mold inspection, it is worth asking hard questions about their licensing and what they are hoping to sell you on the back end. You may even want to enquire further about their relationship with the mold remediation company they recommend. Are they related? Do they get kick-backs? Have they worked with them before?
**Red flag:** A company that both tests and does remediation in Texas is not following state law. If they are willing to cut corners on licensing requirements, consider what else they may be cutting corners on.
Texas regulates mold assessment more rigorously than many states. The Texas Department of Licensing and Regulation (TDLR) oversees two license tiers for mold assessment professionals, and the requirements are not trivial.
A Mold Assessment Technician (MAT) must complete a 24-hour training course from a TDLR-accredited provider, pass a state licensing exam with a minimum score of 70%, submit a completed application with required documentation, and pass a criminal background check. Importantly, a MAT cannot work independently, they must operate under the direct supervision of a licensed Mold Assessment Consultant. This means that any legitimate mold assessment in Texas, even if a technician does the on-site work, always has a MAC involved and accountable for the results.
A Mold Assessment Consultant (MAC) requires either a bachelor's degree in a natural or physical science, engineering, architecture, or building science with at least one year of relevant experience; or at least 60 college credit hours in applicable sciences with three or more years of field experience; or five years of hands-on experience with a high school diploma. On top of those educational requirements, MAC candidates must complete a 40-hour TDLR-accredited training course, pass a separate state exam, and maintain the license through eight hours of continuing education every two years.
In many other states, someone can show up to test your home with no formal training, no exam, and no accountability to any regulatory body. In Texas, you can verify any mold assessor's license through the TDLR public database before you hire them.
The default practice in the mold inspection industry is to run one or two air cassette samples, send you the lab results and call it a completed inspection. Air testing is fast, inexpensive to perform, and simple to explain. It is also, on its own, a fundamentally incomplete picture of what is happening inside a home.
There are three core problems with relying only on air tests.
Mold is not always releasing spores into the air. An air test captures what is airborne at the exact moment the pump runs which is typically run for about five minutes. Mold colonies cycle between active and dormant phases. If the mold in your home is not currently dispersing spores when the inspector arrives, an air test can come back completely clean while significant growth is present. A clean air test result does not mean no mold. It means no mold detected in that room's air at that moment.
Some mold species are heavier and settle rather than staying airborne. Not all mold spores behave the same way. Certain species produce spores dense enough that they fall out of the air relatively quickly and accumulate in settled dust on floors, baseboards, windowsills, and furniture rather than remaining suspended where an air cassette can capture them. If the testing method is limited to air sampling, those heavier species will be missed consistently, regardless of how much mold is actually present.
One room is not the whole house. We regularly hear from homeowners who had a single air test run in their living room, received a clean result, and were told everything was fine. What about the bedroom where the family sleeps? The bathroom? The hallway near the HVAC return? Mold does not distribute evenly through a home. A single sample in one location tells you about that location at that moment and nothing else.
The real cost of inadequate testing: Online forums and neighborhood groups are full of accounts from homeowners who paid for a mold inspection, were told they had no problem, and later discovered significant hidden contamination through follow-up testing. In nearly every case, the original inspector ran one or two air samples, in one or two rooms, and stopped there.
ERMI (Environmental Relative Moldiness Index) is a DNA-based test that analyzes settled household dust rather than air. Because dust accumulates gradually over weeks and months, ERMI gives us a much longer time horizon. Mold that was actively releasing spores last month but is dormant today will still leave its DNA signature in the aged dust on your baseboards and floors. An air test run today would miss it entirely. ERMI also captures those heavier mold species that settle to surfaces rather than staying airborne, the ones that standard air cassettes consistently fail to detect.
So why do many inspectors skip it? Partly cost as ERMI lab fees are significant, making it harder to advertise a low price. Collecting an ERMI sample correctly requires knowing which surfaces to sample, how much dust to collect, and where aged dust is most likely to have accumulated, because incorrect collection produces unreliable results. Not all situations make sense to do an ERMI though as if you collect dust from an entire home, does it bring you closer to finding the mold source? Or is the purpose to match it to the data from the bloodwork from your doctor and see if the home is the source of your body having mold exposure? ERMI is one tool that sometimes we will recommend and often not. Our default is no ERMI but to suggest it in particular situations where it will be helpful and provide additional useful data.
ERMI is not a perfect tool and we do not treat it as one. It tells you what mold DNA is present in your home's dust, but it cannot pinpoint exactly where the mold is growing, whether it is currently active, or whether it is a remnant of a past water event that was already addressed. This is why we use it as part of a multi-method approach alongside air testing, visual inspection, infrared imaging, and moisture mapping rather than as a standalone answer. For a full explanation of how ERMI works, what it can and cannot tell you, and the ongoing debate in the industry around its use, see our detailed guide: What Is ERMI Mold Testing?
A very low price for mold testing almost always reflects one of a few things: a single air test in a single room, a visual-only walkthrough with no lab analysis, a company operating without proper Texas licensing or no report or a report that staples the lab results with no analysis or recommendations for your next steps. None of those scenarios will give you the information you need to actually understand whether your home has a mold problem, where it is coming from and what to do about it.
The goal of a mold inspection is not to collect a sample. It is to answer a question. Questions like: Is there mold in my home? Could it be affecting our health? Is it safe to move into this house? Is the remediation we paid for actually complete? A cheap inspection using one method in one room typically answers none of those questions, even though it produces a report that looks official. You end up spending money and still not knowing what is going on which can lead to far more expensive decisions made on incomplete information.
Most people who call us do not know what kind of mold testing they need. They should not have to. That is our job. What they know is their situation: they feel sick and cannot figure out why, they see something suspicious on a bathroom ceiling, they are about to close on a house and want confidence, they have been dealing with something mysterious for months and need real answers.
We built our packages around those situations rather than individual a la carte services, because we are the experts in what types and quantities of testing are appropriate for different scenarios. Different situations call for genuinely different levels of investigation and what makes sense for a quick baseline check is very different from what is appropriate when someone's health may be at stake and no one can identify the source. We also wanted to be transparent and not make customers do math to add up and guess how many samples they need to figure out what the total price would be.
If you are not interested in a whole home mold inspection but have concerns about one specific leak for example we will come and use our tools to look into that one area and any related areas such as the floor above or opposing wall. This package does not include testing, but the technician may recommend an optional lab test if would be beneficial to you based on our inspection.
Includes visual inspection, infrared thermal imaging, moisture meter, borescope use, 3 indoor air tests, 1 outdoor control sample, and 1 surface swab. Final report with findings and recommendations. Performed by a MAC so we can prepare protocols if needed.
The starting price for this service is $795 and will increase for larger homes (2500+ square feet), time for us to inspect & report on additional areas such as the attic or a casita, additional add-on testing, being outside our service area of Travis Country or needing rushed results. .
Interior and exterior inspection, infrared imaging throughout, moisture meter mapping, HVAC, attic and ductwork inspection, full indoor air quality testing, 3 air tests, 1 physical swabs, plus a call to walk through results together. When you feel it but cannot find it, this is how you find it. We do complete indoor air quality testing in every room of the house in this package as well and we test for humidity, CO2 levels, formaldehyde, VOCs, PM2.5 and more. All providing us clues that help us figure out what is happening in the home.

Mold testing in Austin typically ranges from a few hundred to over a thousand dollars depending on the size of the home, number of samples, and type of testing used.
Prices vary based on factors like home size, number of air or surface samples, accessibility of problem areas, and whether specialized testing methods are used.
A proper mold inspection usually includes a visual assessment, moisture detection, identification of problem areas, and recommendations. Testing may be included or offered separately.
In most cases, mold testing is not covered by insurance unless it is tied to a covered water damage claim. Coverage varies by policy, so it is important to check with your provider.
No. In many cases, visible mold or clear moisture issues can be identified without testing. Testing is most useful when the situation is unclear or needs documentation.
