All tradesmen are particularly busy right now, due to Covid. However, I agree that they are all very difficult to pin down. My neighbour has been trying to find a decorator for months.
My daughter bought a house, last January, which needed extensive renovation.Luckily she works with a lady whose husband does this, and he agreed to ‘fit her in’. Family and friends did all the preparation work. We ripped out the kitchen, doors bannisters and skirtings, and took off all the plaster down to the bare brick. (I quite enjoyed the demolition work) In spite of having umpteen other jobs on the go, the various tradesmen co-operated very well. Apart from the plasterer who did a rush job and had to redo some work everything went pretty smoothly. We all rallied round again and did all the decorating.
She had more trouble with the blind fitters, who had to come back three times.
Judging from all your tales of woe, she has been very lucky. I have a few jobs waiting, but I will wait until next year and see if things improve.
