Trusted Mold Inspectors
in the Tulsa Area
Before you call a mold remediator, you need an independent assessment from a qualified professional. This guide lists verified, unaffiliated mold inspection professionals serving Tulsa and the surrounding area — along with honest notes on what each type of professional can and cannot do for you.
Why We Published This Guide
We are a mold remediation company. We remove mold — we do not test for it, and we never will. A company that both tests and remediates has a direct financial incentive to find more mold than is actually there. We believe that is wrong, and we refuse to operate that way.
The professionals listed on this page have been researched and selected because they provide independent mold assessment services. We have no financial relationship with any of them — no referral fees, no kickbacks, no partnerships. We list them because we believe you deserve honest guidance on who to call before you call us.
Our one ask: when you have your report and protocol in hand, give us a call. That's when we go to work.
The One Rule That Protects You
No matter which professional you choose from this list, one rule applies to every situation: the company that tests your home must have absolutely no financial relationship with the company that remediates it.
This is not a technicality. A mold inspector who also sells remediation services makes more money when they find more mold. That conflict of interest — even when unintentional — can lead to inflated scopes of work, unnecessary remediation, and thousands of dollars in costs you may not have needed to spend.
Before hiring any professional, ask directly: "Do you, or any company affiliated with you, perform mold remediation?" If the answer is yes, or if they hesitate, find someone else.

The Professionals
Listed in order of credential level — from the most rigorous and legally defensible assessments down to initial screening options. Choose based on the stakes of your situation.
Liberty Occupational Health & Safety
Liberty OHS is a Tulsa-based firm led by Joshua Brewer, a Certified Industrial Hygienist (CIH) and Certified Safety Professional (CSP) — the two highest credentials in the occupational and environmental health field. They provide mold inspections, chemical analysis, indoor air quality testing, and written remediation protocols for both residential and commercial properties. Critically, they provide the protocol — they do not perform the remediation themselves.
Liberty OHS is a consulting firm only. They write the protocol; they do not swing the hammer. Their financial interest ends at the assessment, which means their findings are never influenced by what remediation work they might sell you.
Legal situations, insurance claims, large or complex contamination, health-related cases, residential and commercial
Those on a tight budget looking for a quick initial screening
$400 – $900
Highest — CIH reports are legally defensible and accepted by courts and insurers
Marshall Environmental Management
Marshall Environmental Management (MEM) is one of Oklahoma's most credentialed industrial hygiene firms, with over 30 years of service and a Tulsa office. Their team includes multiple Certified Industrial Hygienists, a PhD, and a Fellow of the American Industrial Hygiene Association — the highest recognition in the field. MEM performs mold investigations, indoor air quality surveys, biological monitoring, and laboratory analysis for both residential and commercial clients. They have held long-term contracts with the State of Oklahoma, universities, hospitals, and federal agencies.
MEM is a pure consulting and industrial hygiene firm. There is no remediation division, no abatement crew, and no financial incentive tied to what they find. Their entire business is built on providing accurate, defensible assessments — not on selling follow-up work.
Legal cases, expert witness testimony, insurance disputes, complex contamination, government and institutional clients, any situation where the highest credential level matters
Quick residential screenings or budget-sensitive situations
$400 – $1,000+ (varies by scope)

Indoor Science
Indoor Science is a nationally recognized indoor air quality and mold testing firm that serves the Tulsa area. Every project is supervised by a Certified Industrial Hygienist (CIH), and their methodology goes well beyond a standard inspection — they perform moisture mapping, cause-and-origin reports, protocol development, and laboratory analysis to determine mold type and health risk. They have served clients including NASA, the U.S. military, hospitals, and schools.
Indoor Science does not perform remediation. When remediation is needed, they refer clients to their nationwide network of vetted restoration partners and can provide independent clearance testing after the work is complete. Their revenue comes from assessment — not from what they find.
Complex cases, high-stakes situations, clients who want national-caliber scientific rigor, post-remediation clearance verification
Those who need a local in-person consultation on short notice
$300 – $800+
Very High — CIH-supervised reports with laboratory documentation
Terracon Consultants — Tulsa
Terracon is one of the largest engineering and environmental consulting firms in the country, with a Tulsa office established in 1981. Their industrial hygiene division employs 22 CIHs and 13 CSPs nationwide and has performed everything from individual employee exposure evaluations to community-wide health research projects. For mold, they perform site investigations, bio-sample collection, air quality analysis, forensic investigations, and remediation design and oversight. They are best suited for commercial, industrial, and institutional clients.
Terracon's IH division designs and oversees remediation but does not perform the physical removal work — that is contracted separately. For assessment and protocol writing, their CIH staff operates independently of any remediation contractor. Confirm this separation explicitly when you contact them.
Terracon also offers remediation oversight services. When engaging them for assessment only, confirm in writing that your assessor will have no financial role in any subsequent remediation work.

Cox Environmental
Cox Environmental is a Tulsa-based certified mold inspection firm serving residential and commercial clients throughout Oklahoma. They perform air quality sampling, visible mold identification, moisture mapping, and infrared camera scanning to locate hidden water intrusion. Following the inspection, clients receive a lab analysis from SanAir Technologies, a detailed written report, and a remediation protocol when warranted. Results are delivered within 48 hours. Cox Environmental also explicitly cites Oklahoma law on their website — the statute that prohibits the same company from both inspecting and remediating mold.
Cox Environmental is inspection-only. They cite Oklahoma Statutes tit. 15 § 765.4 directly on their homepage — the law that prohibits a company from both inspecting and remediating mold. Their business is built entirely on assessment, and they provide a list of qualified remediation contractors when mold is found.
