Key points
- Containment = plastic walls and a zipper door around the work area.
- Negative air = a HEPA air machine exhausts air out, so air flows into the work area, not out.
- Spores and dust stay inside while materials are removed.
- Standard practice for significant mold jobs.
How it works
- Seal off the work area with plastic sheeting.
- Install a zipper entry.
- Run a HEPA air machine ducted outside or filtered back in.
- Monitor that air flows into the containment.
- Keep it running until cleaning and clearance are done.
Why it matters
Tearing out moldy drywall releases spores. Without containment, they can spread through the house and HVAC system.
Vault sets up sealed containment with HEPA negative air on remediation jobs. See air scrubbing and HEPA filtration and what to expect.
