Came to customers home for a light fixture replacement, exhaust fan, and exterior light. During my assessment, I noticed there was aluminum wiring. Customer already had devices corrected however no arc fault breakers are present. I highly recommend getting these installed since your circuits were altered. Also, customer had no working smoke detectors in home. Work performed today: Replace exterior light fixture in front of home. Replace exhaust fan in upstairs bathroom. Replace (2) 2x4 fixture bulbs to LED. Install (1) hardwired smoke detector in upstairs hallway. Replace loose electrical box for exterior fixture and install alumicons.
