Attic Mold Removal Cost

Mold remediation isn't just spraying bleach and walking away. It's a multi-step process that requires proper containment, safety, treatment, and restoration. Here's a deep dive into the phases of mold remediation.

🧰 1. Inspection & Moisture Source Identification

What’s involved:

• Visual attic inspection
• Moisture readings (IR cameras or moisture meters)
• Identifying leak sources, venting issues, insulation saturation

🔒 2. Containment & Setup

What’s involved:

• Sealing off the work area with plastic sheeting
• Creating negative air pressure (HEPA fan)
• Floor protection and access control

🧼 3. Insulation Removal (if contaminated)

What’s involved:

• Attic vacuum system for blown-in or batt insulation
• Bagging and disposal of contaminated material

🧪 4. Mold Cleaning & Disinfection

What’s involved:

• Applying EPA-registered products (e.g., Vital Oxide, Benefect, Concrobium)
• Brushing/scrubbing visible mold
• HEPA vacuuming all surfaces

🎨 5. Encapsulation

What’s involved:

• Spraying mold-resistant primer/sealant (e.g., Zinsser Perma-White, Fiberlock Aftershock)
• Covering all exposed wood (rafters, decking, joists)

🌬️ 6. Ventilation Correction & Air Sealing

What’s involved:

• Bathroom fan rerouting to exterior
• Unclogging soffits
• Installing baffles
• Sealing light can penetrations, top plates, pipes

🧱 7. Insulation Reinstallation

What’s involved:

• Installing new blown-in cellulose (often R-49 or greater)
• Final prep, air sealing touch-ups
• 

⚠️ Notes on Pricing:

• Emergency jobs (flood/mold after storms) = higher labor rate
• Crawlspaces or tight attics increase time and hazard pay
• Licensed mold remediation companies often include limited warranties, which may increase overhead
