I look around my house for gfi. I even went out and bought two new breakers at home depot and replaced at electric panel (it's not hard only 3 screws) because they are dual function and had a light on when I reset. Thought it maybe they were bad. Still didn't fix. Finally call Mr electrician. Showed up next day. He arrives and tells my wife (screenshot of $320 fee of) it's a $320 dollar diagnostic fee just to find problem. Whatever I need it fixed. I arrive home ten minutes later. Ask him what's wrong? He won't tell me the problem until I sign/pay for work. Keeps saying there's a short somewhere he has to find. Red flags going off like crazy at this point, but I need my garage to work. Talks me into buying their "silver" package that includes a surge protector to get my money's worth. He says those are normally $600 on their own (which is a $70 part at home depot and 10 minutes install). I ask multiple times how is this fixing the outlet? I'll show you when I'm done so you can fix if happens again. At that moment I knew I got scammed (already paid)and it was gfi's I couldn't find. He shows me an outlet outside, and one in my garage behind my safe amd tells me "you should've looked better". I was pretty livid that I paid $719 for two button presses and a $69 Siemens surge protector (in stock at Home Depot) that I called and spoke with Bobby the manager. A bunch of excuses, you knew price before signing explanations, and finally I'm sorry you feel this way (if I knew they'd charge hundreds of dollars to push two buttons I would've sent them packing). I finally said good day to him and came to realize that this is just a predatory company. DO NOT CALL THIS COMPANY UNLESS YOU HAVE A SAM'S CLUB SIZE BOTTLE OF LUBE!!

He had other jobs already scheduled but was able to come by on Sunday afternoon. (I had shut off everything I could think of so the leak had stopped. Was afraid it was the toilet by the kitchen.) He was able to arrive an hour earlier than he expected which was great. Long store short... he was able to diagnose the actual problem (wasn't the toilet) and the issue was resolved. Very professional, very knowledgeable, very personable. Nice guy and the cost was actually less than I expected for an emergency weekend plumbing call.
