As we arrived Today, Mr. Lain explain to us that his upstairs bathroom light was not working anymore. When we remove the light switch from the wall to see one of the wires was pulling out of the back of the switch. When we started pulling on the wire you could hear it popping and cracking inside of the switch. The light switch was defective. We replaced the existing Singapore light switch with a new one. Once that was done, everything worked properly in the bathroom again. It was nice meeting you Today Mr. Lain! If you have any questions about the estimates, please feel free to give me a call anytime. Thank you, Brandon
