Certified · Independent · Inspection-Only
Our Services
Every service is performed personally by a NORMI- and HBIA-certified microbial biotoxin assessor with 22+ years of field experience, guided by current functional medicine protocols. We don’t sell remediation, and we don’t take referral fees — our independence is your protection.
W. David Winstead is a trained, certified and experienced indoor environmental professional. He is not a Certified Industrial Hygienist and is not held out as one. Our assessments are not technically exhaustive and are not the equivalent of an industrial hygiene evaluation. Where a Certified Industrial Hygienist, professional engineer or other specialist opinion is warranted, we will say so plainly.
Service 01 · Core
Certified Mold & Moisture Inspection
Thorough visual inspection of every accessible building system — HVAC, crawlspace, attic, plumbing chases, wall cavities — combined with moisture mapping using thermal imaging and pin-style hygrometry. We open the systems other inspectors close.
Deliverable: Written Field Findings Summary with photographic documentation, moisture readings, identified problem areas, a prioritized action list, and stated exclusions.
Service 02 · Core
Lab-Verified Sampling & Testing
Six categories of contaminants, not just mold: fungal species, Actinobacteria, endotoxins, formaldehyde, TVOC (Total Volatile Organic Compounds), and MVOC (Mold Volatile Organic Compounds). ERMI and HERTSMI-2 dust testing for CIRS patients per the Shoemaker Protocol. Analysis is performed by independent accredited laboratories. We accept no fee, commission or consideration from any laboratory.
An outdoor baseline sample is collected on every engagement that includes air sampling. This is not discretionary and we do not omit it on screening-level work. Indoor spore counts cannot be meaningfully interpreted without a contemporaneous outdoor control, because indoor spore populations derive substantially from outdoor air. A report presenting indoor counts with no outdoor reference is not defensible. Many firms skip it. We do not.
Deliverable: Laboratory results with contextual interpretation, including HERTSMI-2 scoring where applicable, in a format your physician can work from.
Service 03 · On-Site Assessments
The On-Site Assessment Ladder
Four levels, one methodology. Start where your situation actually sits and move up only if the findings call for it. Every on-site engagement is performed in person by W. David Winstead across our MD, VA, WV, PA and DE service area, and every one includes a written Field Findings Summary.
Why on-site pricing is quoted, not listed
On-site work depends on the size of the conditioned area, how much sampling the situation actually warrants, which laboratory analyses apply, and what you need the report to do. A single published number would be wrong for most people who read it — too high for some, too low for others, and misleading either way. So we send you the full fee schedule and then put you in the right tier on a short call. No pressure, no upsell, no obligation.
Request the full fee schedule →Credit forward
50% of the Sensitivity Walk-Through™ fee credits forward into a Level 1, 2 or 3 assessment booked within 30 days. If you start small and the findings tell you to go further, you are not paying twice for the same visit.
How square footage is calculated
Base pricing covers up to 1,500 square feet of conditioned floor area — all heated and cooled living space on every level, including a finished conditioned basement. Above 1,500, a surcharge of $225 applies for each additional 500 square feet or portion thereof.
This figure is usually larger than the square footage on your tax record or listing, because public assessment records count above-grade finished area only. A home listed at 2,000 sq ft with a finished, heated 1,000 sq ft basement is 3,000 sq ft for our purposes. We ask for both figures at booking and quote from those, not from the listing.
How travel is calculated
No travel charge within 25 miles of Point of Rocks, Maryland. Beyond that radius, travel is billed at $1.25 per mile round trip for the distance exceeding 25 miles in each direction.
Example: a property 58 miles out is 33 billable miles each way — 66 miles round trip — for $82.50. Mileage appears as a separate line item on every quote and invoice and is never folded into a base price.

Service 04 · Continuous Monitoring
Indoor Air Quality (IAQ) Monitoring
Real-time and long-term monitoring of particulate matter (PM 1.0, 2.5, 10), VOCs, formaldehyde, CO2, temperature, and relative humidity. We deploy calibrated instruments and analyze trend data over hours, days, or weeks depending on the case. Critical for sensitized clients, post-renovation evaluations, and HVAC system troubleshooting.
Deliverable: Time-series reports showing when contaminants spike, which often reveals the source — HVAC cycles, cooking, off-gassing patterns.
Service 05 · Specialty
CIRS & MCAS Building Evaluations
Designed around the Shoemaker Protocol and the needs of environmentally sensitized occupants. With your written authorization we coordinate directly with your CIRS-literate physician and document findings in a form that works in a medical chart rather than a real estate transaction.
Deliverable: Physician-ready documentation with HERTSMI-2 scoring and dust mycotoxin panels, describing the conditions found.
We are not physicians. We do not diagnose, treat or interpret clinical laboratory results, and we will not state that any environmental finding caused any symptom or condition. Those judgments belong to licensed healthcare professionals. We describe the building; your clinician decides what it means for you.
Service 06 · The Independence Service
Remediation Scope & Owner’s Representative
We do not perform remediation, and that’s exactly why our clients hire us. When remediation is needed, you don’t want the inspection company also doing the work — that’s a structural conflict of interest with no defensible boundary. No referral fees. No vendor partnerships.
We help you define a clear scope of work, ask qualifying questions of the contractors you are considering, and independently document conditions before and during the work as your representative. We do not direct, supervise or control the contractor’s means and methods — the contractor remains responsible for their own work. For post-work verification, see Post-Remediation Verification below.
Deliverable: Written scope-of-work definition, a contractor qualification checklist, and independent written documentation of conditions observed during the project.

Remote Consultations & Virtual Investigations
For clients outside our regional service area, we offer virtual consultations — phone, video, or a detailed written response — and structured Guided Virtual Microbial Investigations™ at $895, $1,495 and $2,295. The Biotoxin Assessment Kit (+Rental Pump)™ is $725, with an optional AMOLDBUSTER interpretation letter for $395.
Guidance — by phone, video, or detailed written response — is available in all 50 states and the District of Columbia. Investigations involving sampling, whether on-site or virtual, are not available in Texas, Florida, New York or the District of Columbia, which license mold assessment. The restriction applies to the work itself, not to how it is delivered.
⚠ The Industry’s Open Secret
Would You Let a Student Grade Their Own Test?
Marquee Service — Independent Verification
Post-Remediation Verification (PRV)
An independent, third-party look at whether remediation met the objectives it was documented to meet — performed by a firm with no financial stake in the answer. The remediator shouldn’t be the one grading the remediator’s work.
STEP 1
Pre-Remediation Assessment
Document baseline conditions before remediation begins — moisture maps, photo records, scope boundaries.
STEP 2
During-Remediation Monitoring
Optional independent spot checks during active work, documenting whether containment, PPE and HEPA negative pressure are being maintained.
CORE
STEP 3
Post-Remediation Sampling
Independent air and surface sampling after remediation, with a contemporaneous outdoor baseline, analyzed by independent accredited laboratories.
STEP 4
Written PRV Report
Photos, laboratory data, and contextual interpretation measuring post-remediation conditions against the documented baseline.
COMPREHENSIVE
Up to 9 samples plus mycotoxins, MVOC and thermal imaging · medical and legal ready
Before you book a PRV, three things have to be true
1. A documented remediation protocol exists. 2. A baseline record exists. 3. No water event has occurred since the work was completed.
A PRV measures completed work against a known specification. Where no protocol was recorded, where no baseline exists, or where the building has been re-wetted since, there is nothing to verify against — and a report titled “verification” would verify nothing. In that situation the correct engagement is a Forensic Reinvestigation™, described below. We will tell you which one you need before you pay for either.
Why AMOLDBUSTER for PRV: We do not perform mold remediation work. We do not accept referral fees. We have no financial stake in the outcome — only in giving you accurate, defensible findings.
Service 08 · New
Forensic Reinvestigation™
When remediation was done and nobody wrote down what was done. No protocol, no baseline, no scope of work — just a bill and a building you are not sure about. A Forensic Reinvestigation reconstructs the specification from physical evidence instead of verifying against one that was never written.
STANDARD
Level 2 sampling scope, plus full document review and reconstruction of undocumented prior remediation.
COMPREHENSIVE
Level 3 sampling scope, plus reconstruction, Tri-Combo Panel and formaldehyde.
LITIGATION-GRADE
All Comprehensive, plus deposition-ready documentation and a testimony preparation reserve. Covers preparation only — deposition and trial appearance are billed separately.
If you were handed a “clearance letter” by the company that did the remediation, and no independent baseline was ever taken, this is the service you are looking for — not a PRV.
Extended Capabilities
What else we can test, evaluate, and document
Beyond the core services above, our laboratory relationships and certifications allow us to assess a wide range of indoor environmental concerns.
Water Quality Testing
Heavy metals, microbial contamination, PFAS, hormones, and emerging contaminants. Especially important for private well systems.
EMF / EMR Surveys
Electromagnetic field assessments for residential and commercial spaces, particularly for EMF-sensitive occupants and bedroom environments.
Seasonal Comparison
A building behaves differently in July than in January. A summer condensation problem is invisible in a heating-season visit. Available where we performed the original assessment, because comparison requires identical methodology.
LEED IAQ Sampling
Sampling and documentation supporting LEED submittal requirements for commercial new construction and major renovation projects.
Allergen Profile Testing
Pollens, dust mites, pet dander, cockroach, mouse allergens. Coordinated with allergist findings when patient consent is provided.
Litigation & Insurance Documentation
For attorneys, insurance adjusters, and clients in dispute. Comprehensive documentation prepared to withstand scrutiny.
Commercial & Healthcare
Hospitals, clinics, schools, office buildings, multifamily housing. Documentation supporting OSHA and ASHRAE programs.
Emergency Water Event Response
Post-flood, post-fire, and post-storm assessment within our service area. Documentation and assessment only — you engage mitigation and remediation contractors separately.
What we will and will not say about your building
We do not certify a space. AMOLDBUSTER will not describe any building, room or vehicle as safe, healthy, or suitable for any person or for any named condition. We describe conditions found and work performed. We issue no clearance letters and no letters of suitability.
There are no accepted thresholds. There are currently no generally accepted regulatory or scientific threshold exposure limits for mold or microbial contamination in indoor environments. We interpret results contextually and will not certify a property against a threshold that does not exist. Any party representing otherwise is misstating the state of the science.
We are independent. AMOLDBUSTER performs no remediation of any kind, sells no equipment or remedial products, and accepts no referral fees, commissions or consideration from any contractor, laboratory or practitioner. We have no financial interest in what we find.
We are not engineers. Findings regarding the source and pathway of any water event are observational, based on visual inspection and moisture mapping. We do not provide engineering cause-and-origin determinations, and structural and soils questions are documented, photographed, and referred to a licensed engineer.
HBIA disclosure. W. David Winstead holds a partial ownership interest in the Healthy Building Institute of America and serves on its board of directors. HBIA accepts no referral fees and requires the use of no affiliated company. His NORMI certification is independent of AMOLDBUSTER.
