That's interesting I've not seen a bodge of his, care to share? He seems like he does a good job in the videos I've seen.
I've seen a number of his videos which make me shudder. For example one about making good around a new window, another in a toilet the list goes on.
These are so rushed that down the line there will be movement, cracks and damp, but I can understand its partly the way of modern trades. He also makes some incorrect statements about chemicals and tools. What's sad is that he considers this fine to put online which reflects on the state of modern trades really and overall perhaps he's not that bad compared to some.
When I started out renovating my own homes almost 40 years ago, I did work to save money not to get a better result. Now I do work to get a vastly better result and on the occasions I've spent a lot of money on professionals the result has often been poor at best even when I've paid top rates.
