Bold Seagull
strong and stable with me, or...
Thanks for all this advice folks, it's pretty much what we're thinking. I'm going to be calling the coppers and trading standards tomorrow, as well as the man himself to put a stop to the talking to my dad. I didn't think he'd fall for this sort of thing, but clearly he is more vulnerable than I thought he was and this is a concern.
The fact that he hasn't provided us any written documentation so far was an alarm bell even for me, I'm glad that instinct was right.
With regards to the costings and the amount already charged (but not paid) - as there was no agreement in place, can we re-negotiate based on quotes from reputable sources?
I think you can say you are not paying until you see the order receipt and certification for the window to ensure compliance and what was paid for that. You should then ask that the rest of the works be broken down so that you have an invoice which is a mini schedule of works i.e.
1. Remove existing window and dispose of
2. Remove loose masonry, repair and make good opening,
3. 20 bricks needed with mortar and ties as necessary
4. Fit new window including dpcs, mastic and trims etc.
4. make good internal plasterwork
5. Window cost + OHP (this is the contractors cost for ordering and handling the order, normally 10% of the item price).
Once you have that you would have a better understanding of the value of the works and whether they are overpricing. Then you would have a chance to dispute what was being claimed for if you can see that only a few bricks needed pointing in rather than more extensive work.
