Issue: Active Knob and Tube Wiring or Exposed Wiring
- Solution: The house must be rewired before work in wall cavities may begin.
Issue: Mold
- Solution: A mold remediation professional should conduct an in-depth inspection and follow up with proper remediation of affected areas. No work in wall cavities can proceed until the space has been certified clean by the mold professional. (See EPA Protocols)
Issue: Structural Integrity and Wood Rot
- Solution: Make the framing structurally sound, remediate rot, and correct sources of moisture as part of the project.
Issue: Lead-Based Paint (Homes Built Before 1978)
- Solution: Follow the most current version of EPA’s Lead-Based Paint Renovation, Repair, and Painting Rule.
Issue: Natural Draft Combustion Appliance

Issue: Pest-Related Activity or Damage
- Solution: Inspection and treatment by a certified pest control contractor will be necessary before work can proceed.
Issue: Vermiculite Insulation or Asbestos-Containing Materials
- Solution: Obtain professional advice. Vermiculite insulation may contain asbestos and must be tested before wall cavity work begins. Contact the state health department. (See EPA Protocols)
Issue: Leaks or Moisture Damage
- Solution: Include repairs in the project and pay attention to sources of interior condensation.
