Dear XYZ,
On receipt and examination of the pictures of the damage I have obtained the three following independent quotes via the site (whatever you use here) to cover the removal of three screws and the removal and replacement of the three damaged bricks.
These quotes have also confirmed the involvement and cost of a structural engineer for cosmetic damage is disproportionate and unnecessary and the removal of the screws followed by the re-attachment of the dislodged pieces for cosmetic reinstatement is all that is needed.
Accordingly my offer without prejudice stands at (highest/average of the quotes) in full and final settlement of this issue.
I would also remind you that as per the civil procedure rules you have a requirement to act reasonably and keep costs to a minimum. Should this offer be refused we would vigorously defend against any uplift in this offer and argue for a reduction on the basis that:
1) So far your actions relating to the incident have been excessively unreasonable. After the claim of damage it has taken X weeks before any evidence of the damage was presented as you refused to allow us to inspect the claimed damage.
2) The pictures provided could still be of any 3 bricks at any location as there is no wide angle shot showing the location and we have still been denied access to assess and confirm the damage. However we are willing to accept the pictures taken on good faith at this point.
3) We have obtained the opinion of three professional builders who have all stated the involvement and costs of a structural engineer are disproportionate and excessive.
4) Unless otherwise informed, the debris from the damaged bricks which could have been used to restore the cosmetic appearance of the bricks without complete and unnecessary replacement has been disposed of by yourself increasing the costs through no fault of our own.
5) The builder who caused the alleged damage has offered to rectify the problem, and you have refused to allow him to do so.
Accordingly we consider the offer above to be more than reasonable and look forward to confirmation of acceptance. You can do this in writing or by calling (phone number) to provide details on how best to make payment.
Yours sincerely
