just curious - was that electrician a professional or he was just lucky? To be honest I would call him as I have some certain problems with electricity in my house

Yeah, me too, I would call him as well, just because It's too hard in our days to find a good electrician that will be able to fix all of your issues fast and clean. I've called a couple of electrician's to ask them for help, don't know what happened, but i have no light in my house for days, and my renter dont want to fix that, he said this is my trouble. My neighbour told me that I can ask for help from Taren-Point emergency electricians and they will fix everything I need for a good price in minutes. Well, as it was said, those guys fixed everything I had in about 20 minutes and the price was reasonable. Try to find some good specialist's to fix your problems to avoid the next issues
