Working with DocAir was a great experience. They are one of the most honest companies I have worked with. If you are having air quality concerns I would definitely recommend calling DocAir.
Nashville's Premier Engineering-Driven Restoration and Environmental Experts
Expert Restoration. Proven Environmental Solutions. Built on Science.
When something is wrong with your building, unexplained health symptoms, a musty odor that won't leave, a troubling inspection report, utility bills that keep climbing, the answer is never a guess.
DocAir has been solving Middle Tennessee's most difficult building problems since 2002 using the same approach applied in industrial hygiene: diagnose the root cause with data, then recommend only what the evidence supports.
The DocAir Difference, Science Before Sales
Most Nashville restoration and environmental companies are contractors first. They identify a visible symptom, quote a fix, and move on. DocAir is built differently. Founded and led by Barry C. Westbrook, Senior Certified Industrial Hygienist (CIH), Professional Engineer (KY), and Master Plumber, DocAir treats every building as an integrated system. That combination of credentials exists nowhere else in Middle Tennessee.
"Science Before Sales" is not a tagline. It is an operational constraint we place on every project: we will not propose a service we cannot justify with the data collected during a diagnostic evaluation. If your building doesn't need it, we won't sell it.

What DocAir Does
DocAir offers five interconnected service areas, all supervised by a Certified Industrial Hygienist and grounded in the same building-science-first methodology.
Call Us Today! 1 2 3 4 5
Air Quality Testing & Evaluation
IAQ monitoring, duct diagnostics, moisture intrusion investigation, CIH consulting, and post-remediation verification. Every evaluation includes a written interpretation, not just raw data.
Mold & Contamination Remediation
Mold testing, HEPA-scrubbed remediation, containment setup, structural drying, and post-remediation verification. Every mold project carries a written warranty.
Radon & Soil Gas Mitigation
Testing and EPA-compliant mitigation system installation. Critical for Greater Nashville, an EPA Zone 1 high-probability radon area. DocAir installs hundreds of systems annually.
Crawlspace Encapsulation & Moisture Control
Nashville's 70%+ humidity destroys vented crawlspaces over time. DocAir diagnoses the root moisture source, then designs an encapsulation system that addresses it, not just covers it.
Environmental Consulting
Certified Industrial Hygiene (CIH) consulting, commercial IAQ assessments, litigation support, expert testimony, and independent third-party assessments for homeowners, property managers, legal teams, and commercial clients across Middle Tennessee.

Our Process
How Every DocAir Project Works
Whether the issue is mold, radon, crawlspace moisture, or poor air quality, every DocAir project follows the same three-step process: diagnose the cause, fix it with evidence, then prove it's solved.
Diagnostic Evaluation First
DocAir technicians assess the building as an integrated system, not isolated symptoms, using infrared thermography, blower door testing, duct pressurisation fans, moisture meters, and smoke pencil analysis.
This step is not optional, it's what separates a lasting solution from a repeated repair.
Evidence-Based Written Proposal
You receive a detailed scope of work with clear explanations of every recommended action and why the diagnostic data supports it.
We will not propose what we cannot justify, no upselling, no guesswork.
Remediation, Verification & Warranty
Work is completed to the agreed scope. All mold remediation carries a written warranty. Post-remediation testing proves the results scientifically, not just visually.
You receive documentation you can keep, share with buyers, or use in legal proceedings.

Frequently Asked Questions
Have questions about DocAir's testing, remediation, or commercial services? Below are the answers we get most often, every one rooted in real diagnostic data.
Is DocAir a restoration company or a testing company?
Both, and that combination is what sets DocAir apart. Most Nashville companies either test or remediate. DocAir conducts the initial diagnostic evaluation, performs the remediation if the data supports it, and then verifies the outcome with post-remediation testing. Every step is supervised by a Certified Industrial Hygienist. You never have to manage two companies with conflicting interests.
What does 'Science Before Sales' mean in practice?
It means DocAir will not propose a service unless a diagnostic evaluation, using instruments, not guesswork, supports it. If your crawlspace moisture levels are within range, we won't sell encapsulation. If radon tests come back below the EPA action level, we won't recommend mitigation. Recommendations are earned by data, not commission.
Does DocAir serve commercial properties?
Yes. DocAir provides commercial IAQ consulting, industrial hygiene services, commercial HVAC installation and plumbing, air barrier auditing (ABA), and litigation support and expert testimony for attorneys and property managers throughout Middle Tennessee.
How long has DocAir been serving Nashville?
DocAir was founded in Nashville in 2002 by Barry Westbrook, over 22 years of continuous operation in Middle Tennessee. The company's reputation is built on referrals from real estate professionals and residential clients who return for every building problem because they trust the process.
