Hamilton County, TN & North Georgia · IECC Climate Zone 4A Specification
Old Insulation Removal & Attic Restoration
Vacuum extraction of wet, compacted, smoke-damaged, or pest-contaminated fiberglass and cellulose, followed by air sealing and installation of fresh insulation to restore a clean attic.
Quick answer
Vacuum extraction of wet, compacted, smoke-damaged, or pest-contaminated fiberglass and cellulose, followed by air sealing and installation of fresh insulation to restore a clean attic. Humid Zone 4A crawl spaces and vented attics that took on water grow mold and compress the existing insulation, killing its R-value. We remove the contaminated material, dry the cavity, then air-seal and re-insulate from a clean baseline.
Scope of work
- ✓HEPA-vacuum extraction of existing fiberglass and cellulose
- ✓Removal of pest-contaminated or smoke-damaged material
- ✓Mold remediation coordination and disposal
- ✓Air sealing of the cavity before re-insulation
- ✓Fresh blown-in or spray foam replacement
- ✓Attic floor and deck cleanup

What drives project pricing
| Insulation removal (vacuum) | Per sq ft of attic floor |
|---|---|
| Disposal and bagging | Bundled with removal |
| Re-insulation | Priced by the new material chosen |
Ranges are typical for the Chattanooga market before incentives; a locked quote needs an on-site measurement.
What a complete quote includes
- ✓Inspection of existing material and moisture source
- ✓Removal volume and disposal plan
- ✓Air-sealing scope before new insulation
- ✓Replacement material recommendation
- ✓Timeline around containment
Real Transformation Results
Rodent-Damaged Cellulose vs. Vacuumed & Polyurethane Air-Sealed
Indoor Air Quality
Old, contaminated insulation leaks conditioned air and harbors allergens. High-powered HEPA vacuum extraction removes debris down to bare framing, followed by precision air-sealing of every ceiling electrical chase.
Frequently asked questions
- When should old attic insulation be removed before upgrading?
- Remove it if it is wet, compacted, moldy, pest-contaminated, or smoke-damaged. Foaming or blowing new insulation over a wet or contaminated base traps the problem and ruins the new material. A clean, dry cavity is the starting point.
- How is old insulation removed safely?
- We vacuum it with HEPA-filtered equipment, bag it on-site, and dispose of it per local rules. We then inspect and treat the cavity, air-seal, and re-insulate. Pest-damaged areas get extra containment.
