Had problems with one of my exterior lights that burned out causing the rest of the circuit to trip. He removed the fixture, check the wires, removed a piece of the light bulb still stuck in the assembly. And showed me some pointers to prevent something like this happening again. He reinstalled all within 1 hr of first contact to him leaving. Work was performed after 6 pm, in the dark, and still had a cheerful attitude. Recommend to everyone to give him a try.
