Containment and Negative Air in Portland, OR
Containment is what separates remediation from spreading the problem around. Disturbing mold releases spores, and an unsealed work area sends them through the whole building on normal air currents.
Fleur Mold Remediation builds containment on every job across Portland, OR where the affected area justifies it. Poly sheeting seals the work zone with a zipper entry, and a negative air machine with HEPA filtration exhausts outside so air flows into the containment and never out of it. Target is around four air changes per hour depending on volume.
You can verify it yourself. Properly negative containment pulls the sheeting inward.
Critical barriers go over supply and return vents so the HVAC system does not bypass the whole arrangement. Technicians wear PPE and follow decontamination on exit.
The EPA guidance treats roughly 10 square feet as the point where professional handling makes sense. Below that, a homeowner can often manage with sensible precautions, and we will say so rather than quoting a containment job for a patch of bathroom ceiling.
