Hmmm, I don't like getting drawn into arguments but I kind of have to say something in response to the various pics and comments by Maxwell. Contrary to the photo's he has posted not much of his 'work' was satisfactory. I'd had several quotes from several builders prior to employing this guy, none of which were as expensive as he says. But, based on  all of his claims to being a builder, and his pics on his laptop, AND his quote, I employed him. ALL of my previous quotes included removing the wall as it was on top of tiles which had been fixed with yeso. As for his welding skills, most of the finished welds could be broken by a slight push. The osb boards are t&g but none of the t&g's are fitted properly. He broke my window sills, his cement crumbled and there are many concrete blocks with NO cement at all. Notice too that the blocks have been put on upside down.
Re: My Welsh pants, well i'm proud of that Dragon and don't mind showing them off. However, and I won't publish any pics, this 'experienced builder' does like to parade a building site in his underwear and moccasins, neither of which are steel toecapped!
This has become rather farcical now and I think, even though he speaks English, he doesn't actually understand much of it. I attribute this as the main reason for him not doing a good and fair job and for not realising that the wall removal was a clearly stated priority for me. Several people saw his 'finished' roof, not one of those people thought it was finished, not one thought that the work was satisfactory.
It's a pity it's come to this, I would never have disclosed his name publicly and I wanted only to prevent others from wasting their monies on his services. That's all from me.
