AfterMold Inspection & Testing in Austin, TX
Mold inspection and testing in Austin typically costs between $300 and $650 for a standard single-family home, depending on square footage, the number of air samples taken, and whether infrared scanning is included. Most inspections take 90 minutes to two hours, and you’ll have lab results back within 48 to 72 hours. If you’re noticing a musty smell, seeing discoloration on walls or ceilings, or dealing with unexplained allergy symptoms at home, call Marsh Water Damage Austin at (361) 315-6142 and we’ll tell you exactly what we’d check, what it costs, and who’s showing up before we ever knock. If testing confirms a problem, we also offer Mold Remediation services.
We’ve been doing this in Austin since 2005, and we approach mold testing differently than companies that just sell tests. Our Mold Remediation in Austin work starts with inspection, because you can’t fix what you haven’t accurately identified. Marsh Water Damage Austin is built on the Threshold Verified standard: every technician is background-checked, identity-verified, and sent to you by name and photo before the visit. You’ll know who’s coming, see their badge at the door, and get a written price before any testing begins. No surprises, no strangers.
Key Takeaways:
- Mold inspection in Austin runs roughly $300 to $650 for most homes, with lab fees included in that range.
- We send the technician’s name and photo before arrival, and they show a photo ID badge at the door, every time.
- You get a written price before any work starts, and a written guarantee on every report.
- Our 365-Day Done Right Promise means if something isn’t right within a year, we make it right, free second visit included.
When You Need Mold Inspection & Testing
Mold isn’t always visible. In Austin’s climate, especially after the spring storm season and the humidity that settles into crawl spaces and slab foundations, mold grows behind walls, under flooring, and inside HVAC ducts long before you see a single spot on the drywall. Here are the situations where inspection and testing are the right call:
- You smell something musty or earthy, but can’t find the source. This is the most common call we get in older neighborhoods like Hyde Park, Allandale, and Cherrywood, where pier-and-beam foundations trap moisture under the house and smells drift up through floorboards.
- A pipe leaked, an AC condensate line overflowed, or a toilet wax ring failed. If water sat for more than 24 to 48 hours, mold has likely started. Testing tells us what genus and how much is airborne before we decide on remediation scope.
- You’re buying or selling a home in Austin. Pre-purchase mold inspections are increasingly standard in Travis County real estate transactions, especially for homes with crawl spaces, basements, or a history of roof leaks.
- Someone in the home has persistent allergy symptoms, asthma flare-ups, or chronic sinus issues that improve when they leave the house. Certain molds, like Stachybotrys and Aspergillus, trigger respiratory responses, and air sampling is the only way to know if they’re present at elevated levels.
- You saw a remediator’s quote that doesn’t include testing. If a contractor wants to tear out drywall without first identifying the mold type and moisture source, that’s a red flag. Testing protects you from paying for the wrong fix.
- After a flood or major storm event. Austin’s flash floods, especially in low-lying areas like Onion Creek, Dove Springs, and parts of East Austin, push water into homes fast. Even after drying, mold spores can remain in insulation, drywall, and carpet padding.
Our Mold Inspection & Testing Process
Here’s exactly what happens when you call Marsh Water Damage Austin for mold testing:
- You call (361) 315-6142 and talk to a live person. Not a voicemail, not a chatbot. We answer 24/7, including holidays, because mold doesn’t wait and neither should you.
- We schedule a time that works, and send you the technician’s name and photo before the visit. That’s the Threshold Verified standard. You’ll know who’s coming, and they’ll show a photo ID badge at the door.
- The technician walks the property and asks targeted questions. We want to know about past leaks, condensation on windows, bathroom ventilation, crawl space access, and any symptoms family members are experiencing. Context matters as much as samples.
- We take moisture readings, use infrared scanning where needed, and collect air and surface samples. Air samples are drawn with a calibrated pump into cassettes, and surface samples are collected with swabs or tape lifts. We send everything to an independent lab, which means we have no financial incentive to inflate results.
- You get a clear written report with lab results and our recommendation. We tell you what we found, what it means in plain English, whether remediation is needed, and what it will cost. No jargon, no fear-mongering, no upsell. If remediation isn’t needed, we say so.
Our technicians carry credentials from the IICRC and RIA, and they use moisture meters and thermal imaging tools from Dri-Eaz and Phoenix. That’s the same equipment used on big commercial losses, applied to your house.
Mold Inspection & Testing Pricing in Austin
Here’s the honest money conversation. Mold testing in Austin is not outrageously expensive, but you should know what you’re paying for before you commit. If you’re wondering How Much Does Mold Remediation Cost? (2026 Price Guide) - Austin, TX, we can cover that too. Our prices are written down before any work starts, and they don’t change after testing begins.
- Visual inspection with moisture mapping: $150 to $250. We walk the whole property, document visible mold, measure moisture with a pin-type meter, and tell you what we see. No samples, no lab fees.
- Air sampling (per sample): $75 to $125. Most homes need two to three samples: one outdoor baseline and one or two indoor samples from problem areas. The lab identifies mold genus and concentration.
- Surface sampling (swab or tape lift, per sample): $50 to $90. Useful when visible mold is present and you need to know the specific species.
- Full inspection with 2 air samples and 1 surface sample: $350 to $550. This is the sweet spot for most Austin homes, and it’s what we recommend for pre-purchase inspections or when symptoms are present but mold is not visible.
- Larger homes (3,000+ sq ft) or crawl space inspections: Add $100 to $200. Crawl spaces in Austin take extra time and require additional sampling due to the high humidity environment under pier-and-beam homes.
What affects cost: square footage, the number of samples collected, whether infrared scanning is needed, and accessibility of crawl spaces or attics. What does not affect cost: how nice the house is or how worried you sound on the phone. We quote the same to everyone.
Every job gets a written price before any work begins and a written guarantee on the report. If the inspection fails to identify a mold problem within 365 days and you find mold in an area we tested, the 365-Day Done Right Promise applies. We come back and make it right, free second visit included.
FAQs – Mold Inspection & Testing
How much does mold inspection cost in Austin?
A standard mold inspection in Austin costs between $300 and $650, with most single-family homes falling in the $350 to $550 range for a full inspection with two air samples and one surface sample. Visual-only inspections run $150 to $250. Every Marsh Water Damage Austin quote is written down before any work starts, so you’ll know the exact number before anyone steps inside. Call (361) 315-6142 for a free estimate.
Can you test for mold the same day?
Yes, in most cases. We answer calls 24/7 and can often schedule a same-day or next-day inspection in Austin, especially for active leaks or visible mold situations. Lab results take 48 to 72 hours, but the inspection itself can happen quickly. Call us and we’ll tell you what today looks like.
Is it cheaper to test for mold myself with a store-bought kit?
Store-bought kits cost less up front, usually $10 to $40, but they have real limitations: they only tell you that mold spores exist in the air, which is true of virtually every home on earth. A professional inspection measures the concentration, identifies the genus, pinpoints the moisture source, and gives you a documented report you can use for insurance claims or real estate transactions. If the source is severe, we may recommend Mold Removal as the next step. A $40 kit won’t do any of that. Call (361) 315-6142 if you want a real answer, not a sell.
Do I really need mold testing before remediation?
In most cases, yes, especially in Austin where humidity and flood events create conditions for multiple mold types. Testing tells us what we’re dealing with, where the moisture is coming from, and how far it has spread. That informs the Mold Remediation plan and prevents paying for tear-out that wasn’t necessary or missing mold that was hidden. If a company skips testing and goes straight to demolition, you should ask hard questions.
Can you come today if I think there’s mold after a flood?
Yes. We answer live 24/7 and maintain availability for emergency inspections after storms and flooding in the Austin area. If water sat for more than a day, don’t wait for visible mold to appear. Call (361) 315-6142 and we’ll get someone out to you.
