Commercial is a different job
Commercial Mold Jobs Start With a Protocol, Not a Spray Bottle
Residential jobs often start with a walk-through and a quote. Commercial jobs in Basehor usually start with an independent assessor who inspects, takes readings and writes a remediation protocol that spells out containment, removal and clearance criteria. Keeping assessment and remediation separate protects the owner, and some states actually prohibit one firm from doing both on a single project.
Commercial crews work to IICRC S520, the recognized remediation standard, and to OSHA requirements for respiratory protection and PPE. Engineering controls do the heavy lifting: critical barriers sealing doors, vents and penetrations, HEPA negative air machines exhausting the work zone, and a manometer at the containment wall logging the pressure differential so the building manager can see containment is holding.
Commercial calls cluster around the same sources: ponding water on flat roofs working through the membrane, condensation on chilled-water piping, hotel PTAC sleeves and drain pans, walk-in cooler walls in restaurants and apartment units found moldy at turnover. Each one needs a crew that can work around tenants, guests, students or patients.
