In all fairness, you have my sympathy. If you don’t know, you don’t know.
My mate, who is an architect, decided to renovate his own flat rather than getting someone in; he reckons it cost him nearly three times as much plus his time. He had to buy loads of tools, and did most jobs twice as he was learning as he went. Place looked amazing but nearly killed him. He won’t change a fuse these days, always gets someone in.
