Remove asbestos, vermiculite, and knob and tube wiring to allow for weatherization installation.
For buildings with a commercial meter, the Sponsors of Mass Save offer incentives for the following abatement and mitigation:
- Removal of vermiculite/ asbestos
- Removal of knob & tube wiring
- Knob & tube wiring verification
If vermiculite or asbestos is present, it must be abated prior to the insulation work. Knob and tube wiring (outdated electrical wiring) must also be remediated for safety purposes prior to insulation upgrades. Rebates are available to help address these pre-weatherization barriers.
