Mold Remediation

We find the moisture source, contain the affected area, remove contaminated materials, HEPA-clean the envelope, and leave the space drier than we found it. IICRC S520 principles, no shortcuts.

Equipment

What we bring to the job

Professional-grade tools matter — they decide whether your space gets surface-cleaned or actually restored. Here's the gear we use on every mold remediation job.

HEPA Air Scrubbers
Commercial-grade air filtration units (500–2,000 CFM) run continuously inside containment — filter 99.97% of spores from the air the whole time we work.
Negative Air Machines
Create negative pressure inside the work area so spores can only travel OUT through HEPA filters, never into unaffected rooms.
ZipWall Containment + 6-mil Poly
Full floor-to-ceiling containment with airlock entry. No drywall dust or spores migrate into the rest of the home.
Benefect Decon 30 (Botanical)
Thyme-oil-based EPA-registered antimicrobial — kills mold and bacteria without the bleach smell or VOC load. Safe around kids, pets, immunocompromised clients.
Moisture Meters (Pin + Pinless)
Protimeter-class meters verify the substrate is dry before we close anything back up — the #1 reason mold comes back is skipping this step.
Thermal Imaging Camera
FLIR-class imager maps moisture behind walls, under floors, and around plumbing chases — finds the wet area you cannot see.
Process

How we do it

Same six-step process every time, so you know exactly what to expect.

  1. 1
    Assessment + moisture source
    Before we touch mold, we find where the water is coming from. No point removing mold if the leak is still active.
  2. 2
    Containment
    ZipWall barriers seal the work zone. Negative air machine runs before we cut anything.
  3. 3
    Remove affected materials
    Porous materials (drywall, insulation, carpet) that are visibly colonized come out and are bagged double-layer for disposal.
  4. 4
    HEPA clean + antimicrobial
    Every surface inside containment HEPA-vacuumed, then wiped with botanical antimicrobial. Air scrubbers run through the entire process.
  5. 5
    Dry to standard
    We dry the cavity with air movers and dehumidifiers and meter-verify moisture is back to baseline before anything closes up.
  6. 6
    Post-remediation verification
    Visual + moisture verification documented. Third-party clearance testing available on request for insurance jobs.

FAQ

Questions we get

Can I stay in the house during remediation?

In most cases yes — containment isolates the work area. For large jobs or sensitive occupants (infants, immunocompromised), we recommend staying elsewhere during the active removal day.

Do you do testing?

We visually assess and can arrange third-party air and surface sampling through an independent indoor environmental professional. For insurance or litigation jobs this is often required.

Will insurance cover it?

Depends on the cause. Sudden events (burst pipe, roof leak) are usually covered; long-term leaks and humidity are often excluded. We provide photo documentation either way.

How do I prevent it from coming back?

Fix the moisture source, ventilate wet areas (bath fans vented outside), keep indoor humidity below 55%, and address any new leaks within 24–48 hours.
