Mold growth on a wall
Mold

Bring in a credentialed third-party indoor-air professional.

Roughly 100,000 species could be classified as mold. Identifying which one you have — and which one matters — is not a contractor's job. We coordinate with a 3rd-party Hygienist and execute against their protocol.

Process

Containment first. Always.

  1. 01
    Source identification. Find the moisture source. Mold doesn't grow without water — fix the cause or it will come back.
  2. 02
    Containment. Plastic barriers, negative-air machines, and a clearly marked work zone before any disturbance.
  3. 03
    Hygienist engaged. We bring in a 3rd-party 3rd-party indoor-air professional (ACAC- or AIHA-credentialed) to test, identify species, and write the remediation protocol.
  4. 04
    Removal & cleaning. Affected materials removed under containment. HEPA vacuuming and antimicrobial application on what remains.
  5. 05
    Post-remediation verification. Hygienist returns for clearance testing. We don't close the wall until clearance passes.
  6. 06
    Build-back. Drywall, paint, flooring, and finishes restored.
Testing & identification

Why we don't guess at species.

Approximately 100,000 organisms could be classified as mold, and the remediation protocol depends heavily on which species is present. Stachybotrys (black mold) requires a vastly different scope than Cladosporium, which is in nearly every house in the Midwest.

We work with three 3rd-party laboratory vendors and go with whichever can get results back fastest. The Hygienist's report is the source of truth for the project — not our opinion or anyone else's.

Roles & licensing

  • Missouri testing. Mold testing is performed by a credentialed third-party indoor-air professional (ACAC or AIHA). Wiley Services holds the Missouri DHSS Lead Renovator (RRP) license for use of EPA-recognized lead test kits on components we will disturb in pre-1978 housing; formal lead inspection or risk assessment is performed by separately licensed Lead Inspectors or Risk Assessors.
  • Kansas testing. We hire a 3rd-party Hygienist for Kansas work — state requirements differ.
  • Verification. All findings confirmed by 3rd-party clearance testing.
  • Abatement. Specialty abatement crews on standby through our subcontractor network.
Pricing

What mold remediation typically costs.

Small

$2,000 – $5,000

Localized, single area, accessible.

Moderate

$5,000 – $10,000

Multiple rooms, HVAC involvement, or hidden growth in cavities.

Large

$10,000+

Whole-home, structural saturation, or specialty species.

Pricing depends heavily on species, accessibility, and the Hygienist's clearance protocol. Hiring a 3rd-party indoor-air professional (ACAC- or AIHA-credentialed) takes the guesswork out of scope — and out of pricing.

See something growing? Don't disturb it.

Disturbing mold spreads spores. Call before you cut, scrape, or wash. We'll set containment first, identify second.
