Get 3 quotes from somewhere like trustatrader or ratedpeople from 3 builders/bricklayers. Also ask them to confirm if a structural engineer would be needed. (it wont)
Id reply something like this
Morning All,
I received an email reply for the above message
"It’s very childish to blame us for not saving the broken pieces of the bricks also to claim which can be used to put together/repair the brick. It appears like giving unreasonable reasons to delay forever.
We have given enough time already however we give final notice with further 14 days from today(ie.9/11/2021) to repair damages caused by them as last opportunity to settle things with out dispute. We have tried our level best to avoid a dispute and settle things amicably but seems like the other party has no intention to conclude this matter."
I still don't understand, Did he went through my email or not!.I did clearly mention that as per the quotes attached. I would be offering average of the quotes which would be £120 in full and final settlement of this issue.But he is still giving final notice for settling things.
