I am writing to thank Summer for doing an excellent job installing our new conservatory. We are very pleased with finished product.
I am also very impressed with the speed of response to addressing the final and outstanding work items which were done speedily and effectively.
All too often people are quick to complain, so in your case writing this letter is a pleasure.
My wife and I were impressed with the staged payment process, which gives increased confidence to customers and supports quality delivery of the product and service.
