Be more careful.Just learn from the experience, single pane glass won't be much to replace, not knowing you technique I can't say for certain, but your very unlikely to have cracked it, good chance it was already done and you didn't notice, did you hear it crack ? Darran
You forgot 'deny all knowledge and do a runner'
The chap I use would probably charge around £25 all in.Hopefully, the customer is upstanding and honest, my money is on that it was previously cracked.Darran
Depends if the building is listed. If it is the cost will go up, you'll be looking at about £45.00 for supply and deliver as far as I remember for glass that's supplied for buildings of this nature. There's a company supplies panes suitable if this is the case, I can't remember what the type of glass is called, something like Royal. Anyway, if you need to know I can find out for you when I'm back in the country next week.
Really pleased for you, nice to have an honest customer too Darran
