Mold Remediation Cost in Texas: Published Estimates, What Drives Price, and When a License Is Required
Quick answer: Commonly published national estimates put a typical professional mold remediation job at roughly $1,223–$3,757 (Angi, average $2,368) or $1,500–$6,000 (HomeGuide), with per-square-foot estimates of $10–$25 (Angi) to $15–$30 (HomeGuide). A mold inspection is estimated at $303–$1,075 (Angi, average $689). These are national figures, not a Texas survey: real Texas quotes vary by size, material, HVAC involvement, containment, and metro. In Texas, anyone you hire to remediate 25 contiguous square feet or more generally needs a TDLR license (Occupations Code §1958.102), and the assessor and remediator must be separate on the same project (§1958.155). Get 2–3 written quotes from licensed firms on the same protocol.

Published Mold Remediation Cost Estimates
The tables below reproduce ranges from named consumer cost guides, with each page's own date. They are national estimates, not Texas-specific measurements, and the publishers do not always say how large the underlying jobs were or exactly what was included. Use them to sanity-check a quote, not to predict one.

HomeAdvisor, part of the same Angi family of sites, publishes the same $1,223–$3,757 range and $2,368 average (HomeAdvisor, updated Jun 19, 2026), so we treat it as the same data rather than independent confirmation. Angi's own page also contains an older-looking FAQ range ($1,125–$3,350, about $2,400 average); we use its headline figure.
Inspection and testing estimates
| Item | Published estimate | Source (page date) |
|---|---|---|
| Mold inspection | $303–$1,075 (average $689) | Angi (updated Oct 5, 2026) |
| Mold test (air and surface samples) | $250–$500 | Angi (updated Oct 5, 2026) |
| Air test / swab test (per Angi) | $250–$350 air (up to $700 extensive) · $200–$300 swab | Angi (updated Oct 5, 2026) |
| Mold inspection (older page) | $300–$650; up to $1,000 for large homes | HomeGuide (page dated Sep 15, 2023) |
Sampling is not always needed. EPA's Brief Guide to Mold, Moisture, and Your Home says that in most cases, if visible mold growth is present, sampling is unnecessary, and that no EPA or other federal limits have been set for mold or mold spores. In Texas, a licensed assessor still writes the protocol for a regulated job, but ask what decision each lab sample will inform before you pay for it.
What Drives Mold Remediation Cost in Texas
Every source we reviewed agrees on the same core variables. Here is how they play out on a Texas job:
Size of the contaminated area
Published guides price by affected square footage, but small jobs rarely scale down linearly—setup, containment, protective equipment, and disposal cost roughly the same whether the patch is 20 or 60 square feet. In Texas, crossing 25 contiguous square feet also changes who may legally do the work (see the licensing section below).
Material and how much must be removed
EPA notes that absorbent or porous materials such as ceiling tiles and carpet may have to be thrown away if they become moldy. Cleaning a non-porous surface is a different job from cutting out drywall, insulation, or subfloor. Rebuild (new drywall, paint, flooring) is often quoted separately from remediation.
HVAC involvement
Mold in an air handler or ductwork is one of the most expensive line items in every guide we reviewed. EPA advises not to run an HVAC system you know or suspect is contaminated, because it can spread mold through the building—so HVAC scope also affects how soon a home is usable.
Containment and access
Attics, crawl spaces, and wall cavities take more labor and setup than an exposed bathroom wall. Larger jobs typically require plastic containment, negative air, HEPA filtration, and more time on site, which is why the same square footage can price very differently by location in the home.
Water source and category
Remediation without fixing the moisture source usually fails. EPA states that if you clean up mold but do not fix the water problem, the mold will most likely come back. Plumbing, roofing, or drainage repairs are commonly separate trades and separate bills. Sewage or other contaminated water calls for a professional experienced with that kind of damage, per EPA.
Texas two-firm structure
On a regulated Texas project, assessment and remediation are performed by different licensees (Occupations Code §1958.155). That means separate quotes for the assessor’s protocol and clearance and for the remediator’s work. National “remediation cost” averages may not make clear whether those assessment fees are included.
Metro labor costs and scheduling
Labor rates, disposal fees, and contractor availability vary by metro and by season. Demand can rise after major storms and flooding, which may affect both price and lead time. We do not publish city-specific multipliers because we have not found a public source that measures them reliably.

Inspection vs. Remediation vs. Clearance: Three Different Line Items
Many national cost guides describe one company that inspects, removes, and re-tests. On a regulated Texas project that is not how it works. Occupations Code §1958.155 bars a license holder from performing both mold assessment and mold remediation on the same project, and bars anyone from owning an interest in both entities on that project. Budget for three pieces:
| Stage | Who (TDLR license) | What you are paying for |
|---|---|---|
| 1. Assessment & protocol | Mold Assessment Consultant (MAC) / Assessment Company (ACO) | Inspection, any sampling, and a written work analysis listing rooms or areas, quantities of materials, methods, and clearance criteria before remediation begins (§1958.151). |
| 2. Remediation | Mold Remediation Contractor (MRC) / Remediation Company (RCO) | A written work plan that follows the protocol (§1958.152), TDLR project notice at least five days before starting, or by the next business day in an emergency (§1958.153), the removal and cleaning, and before-and-after photos (§1958.156). |
| 3. Clearance & certificate | Assessor (MAC/ACO)—not the remediator | Post-remediation evaluation. The Certificate of Mold Remediation the remediator delivers within 10 days must include the assessment licensee's statement that the mold was remediated per the protocol (§1958.154). |
We did not find a reliable public source for clearance pricing, so we do not publish a number. Ask your assessor to quote protocol and clearance together in writing, including what happens (and what it costs) if the first clearance fails. TDLR's mold FAQ notes that a consultant who did not prepare the protocol in advance cannot declare that the project achieved clearance, so switching assessors mid-project can add cost. For the certificate itself, see our Certificate of Mold Damage Remediation (CMDR) guide, and for why the roles are split, see assessor vs. remediator in Texas.
Texas Regional Factors: Humidity and Flood Risk
Texas is large enough that climate and water risk differ sharply by region. These are qualitative patterns, not price adjustments—we have not found a public dataset that measures mold remediation prices by Texas metro, so we do not publish one.
- Gulf Coast (Houston, Beaumont–Port Arthur, Galveston, Corpus Christi): Persistently humid air and hurricane, tropical-storm, and flood exposure. Expect more emphasis on drying, moisture source correction, and sometimes larger affected areas after water events.
- Central Texas (Austin, San Antonio, Hill Country): Flash-flood-prone terrain and heavy-rain events can produce sudden water intrusion, plus summer humidity that strains HVAC dehumidification.
- North Texas (Dallas–Fort Worth): Severe storms and hail can lead to roof and window leaks that show up later as attic or wall mold; attic access can drive cost.
- Rio Grande Valley and South Texas: Heat and humidity for much of the year; condensation around HVAC equipment and ducts is a frequent concern.
- West Texas and the Panhandle (El Paso, Lubbock, Amarillo, Midland–Odessa): Drier climates generally mean fewer humidity-driven problems, but plumbing leaks, roof leaks, and evaporative-cooler moisture can still cause localized mold.
Wherever you are, the cheapest remediation is the one you avoid. EPA recommends keeping indoor humidity below 60 percent, ideally between 30 and 50 percent, and fixing leaks and drying wet materials quickly (EPA Brief Guide). To find licensed firms near you, search your city or browse the statewide directory.
DIY vs. Licensed: The 10 sq ft Guidance and the 25 sq ft Texas Threshold
Two different numbers show up in mold advice, and they mean different things:
- About 10 square feet (EPA guidance, not a Texas law). EPA says that if the moldy area is less than about 10 square feet (roughly 3 ft by 3 ft), in most cases you can handle the job yourself. For more than 10 square feet or a lot of water damage, EPA points to its Mold Remediation in Schools and Commercial Buildings guidance. For sewage or other contaminated water, EPA recommends a professional experienced with that damage; for a suspected HVAC problem, it says not to run the system and to consult its air-duct guidance first.
- 25 contiguous square feet (Texas licensing threshold). Under §1958.102(c), a person does not need a license to perform mold remediation in an area where the contamination affects a total surface area of less than 25 contiguous square feet. At 25 contiguous square feet or more, a company you hire to remediate generally must hold a TDLR mold remediation license. TDLR's FAQ puts it this way: in most instances, areas of visible mold of less than 25 contiguous square feet can be cleaned up by people who are not licensed.
Owner exemptions (and what SB 1255 did not do)
§1958.102(e) exempts an owner, or the owner's managing agent or employee, performing mold assessment or remediation on residential property the owner owns with fewer than 10 dwelling units—unless that agent or employee is in the business of doing mold work for the public. That exemption predates SB 1255. SB 1255 (effective September 1, 2025) repealed §1958.102(b), the former supervised-employee exemption. SB 1255 did not create the under-10 rule. Legal permission to DIY is also not the same as EPA's practical safety guidance; see our Texas mold laws guide for the full exemption picture.
Small jobs with a licensed firm still follow the rules
If you hire a licensed remediator for an area under 25 square feet, TDLR's FAQ says the licensee is not exempt: they must still prepare a work plan that follows a protocol from a licensed Mold Assessment Consultant, though no TDLR project notification is required. That is one reason a small licensed job can cost more than a per-square-foot estimate suggests.
How to Compare Mold Remediation Quotes in Texas
- Get the assessor's written protocol first, then ask 2–3 licensed remediators to bid on that same protocol so quotes are comparable.
- Ask each bidder to separate containment, removal, HEPA cleaning, disposal, HVAC work, and rebuild into line items.
- Confirm who fixes the moisture source and whether that is in or out of the quote.
- Confirm clearance is by your independent assessor, and who pays if clearance fails.
- Put TDLR license numbers for every individual and company on the contract, then verify each TDLR mold license on TDLR License Search.
- Be cautious of a quote far below the published ranges with no protocol, or one firm offering to test, remove, and clear the same project.
Methodology and Disclaimer
- No proprietary survey. Texas Mold Remediation did not survey contractors or homeowners. We do not publish a “Texas average” or city price table.
- What we cite. Every dollar figure on this page is a third-party estimate copied from a named, linked public page (Angi, HomeGuide, HomeAdvisor), shown with that page's own date and accessed October 5, 2026. Those publishers describe their own methods (customer-reported project costs and internal databases); we have not audited them.
- What is qualitative. Regional climate notes, clearance pricing, and Texas-specific cost drivers are explained without numbers because we did not find a reliable public source to cite.
- Estimates vary. Actual prices vary by size of the contaminated area, materials, HVAC involvement, containment, access, water source, and metro. Get 2–3 written quotes from TDLR-licensed firms.
- Legal information. Licensing statements come from Occupations Code Chapter 1958 and the TDLR mold FAQ. This is general information, not legal, insurance, or medical advice.
- Neutral directory. We list licensed professionals and do not perform mold work or set prices. Listing on our site is not an endorsement.

Frequently Asked Questions
How much does mold remediation cost in Texas?
We are not aware of a reliable public Texas-only average, so we cite national estimates. Angi (updated July 9, 2026) publishes a typical range of $1,223 to $3,757 with a $2,368 average, and $10 to $25 per square foot. HomeGuide (February 5, 2026) publishes $1,500 to $6,000, or $15 to $30 per square foot. Treat all of these as estimates: actual Texas prices vary with the size of the area, materials, HVAC involvement, containment, and metro. Get 2–3 written quotes from TDLR-licensed firms.
How much does a mold inspection or assessment cost in Texas?
Angi’s mold inspection page (updated October 5, 2026) lists $303 to $1,075 with an average of $689, and $250 to $500 for a mold test with air and surface samples. In Texas, a regulated project generally needs a licensed mold assessor (MAC/ACO) to prepare the protocol, and post-remediation clearance is also an assessment function, so ask the assessor to quote both up front. These are estimates; confirm with licensed local assessors.
Do I need a licensed mold remediator for a small area in Texas?
Texas Occupations Code §1958.102(c) says a person does not need a license to remediate an area where the contamination affects a total surface area of less than 25 contiguous square feet. At 25 contiguous square feet or more, a company you hire generally needs a TDLR mold remediation license. Separately, §1958.102(e) exempts an owner (or the owner’s managing agent or employee) working on residential property the owner owns with fewer than 10 dwelling units, unless that agent or employee does mold work for the public. If you hire a licensed remediator even for a small job, TDLR’s FAQ says they must still follow the rules, including working from a licensed assessor’s protocol (project notification is not required under 25 sq ft).
Why does a Texas mold job involve two separate bills?
Occupations Code §1958.155 prohibits a license holder from performing both mold assessment and mold remediation on the same project, and bars anyone from owning an interest in both entities on that project (with a narrow school-district carve-out). So a regulated job typically has an assessor invoice (protocol and clearance) and a separate remediator invoice. Repairs to the water source and rebuild are often separate again.
Is clearance testing included in a remediation quote?
Often not, and in Texas the remediator cannot be the one who clears its own work on a regulated project. Under §1958.154, the Certificate of Mold Remediation must include a statement by a mold assessment license holder that the mold was remediated as outlined in the protocol. TDLR’s FAQ adds that a consultant who did not prepare the protocol in advance cannot declare clearance. We did not find a reliable public source for clearance pricing, so ask your assessor for a written clearance quote at the start.
Does homeowners insurance pay for mold remediation in Texas?
It depends on your policy and on what caused the mold. Coverage questions are between you and your insurer, so read your policy and call your agent before work begins. Keep the assessor’s protocol, the remediator’s invoices, photos, and the Certificate of Mold Damage Remediation (CMDR); those records matter for claims and for disclosure if you sell.
Did SB 1255 create the under-10-units owner exemption?
No. SB 1255, effective September 1, 2025, repealed Occupations Code §1958.102(b)—the former supervised-employee exemption. The owner exemption for residential property with fewer than 10 dwelling units is §1958.102(e), which was already in the law before SB 1255.
Why don’t you publish a Texas price table by city?
Because we have not found a public data source that measures mold remediation prices city by city in Texas, and we will not invent one. This page cites dated national estimates from named sources, explains the Texas-specific factors that move a quote, and recommends getting 2–3 licensed local quotes on the same written protocol.
