If your home was built between the mid-1960s and late 1970s, you may have aluminum wiring.
Some insurers will not provide or renew insurance coverage on homes without an ESA inspection. You may need to repair or replace the wiring and provide your insurer with a copy of the ESA Certificate of Acceptance. Ask your insurance company for their requirements.
Each home is different and must be assessed on its own. ESA recommends hiring a Licensed Electrical Contractor (LEC) familiar the techniques required for working with and repairing aluminum wiring. The LEC should do an assessment, make the necessary repairs, and have the work inspected by ESA. Ask the LEC for a copy of the Certificate of Acceptance for your records.
