respecting the builders and trades is key. decent ones know their stuff, and have a wealth of knowledge. My builders have told me about how other customers have talked down to them, expect them to work miracles, expect things that were not included in the quote, cant make decisions for tit and then complain things take too long, withhold payment etc. I actually felt sorry for them as they probably have to deal with so many arseholes. Youd never go to your dentist and tell them how to do their job because that would be disrespectful, yet people do it to trades people all the time. Yes there are cowboy builders etc but I reckon the chances are Zanna and her snobby mate jojo have been rude and disrespectful throughout. I wouldn’t dream of going round my extension with red stickers to point out snagging. I’d just make a list and chat to my builder about it like a normal human instead of being a passive aggressive twit.
