Dear Richard,
First, I should like you to know how highly we regarded and appreciated your team. They were highly professional, very caring and informative, and a pleasure to have on site. They did an excellent job, with a minimum of inconvenience to us. Be assured I shall be delighted to recommend them.
I am particularly grateful to you for your concerns, and the extra effort made by your team, regarding the defective pane in the stair (right).
I am happy with your final invoice, and have now settled it by faster payment.
Thank you for your help in the project - a small one for you, but a large commitment for us. I am sure I do not need to say how delighted we are with the result.
Regards
David
