I just wanted to let you know how pleased I am with the new windows in my kitchen and bedroom. Your workmen did a wonderful job, I wouldn’t have known that I had had any work done were it not for the fact I was present. Your fitters were so clean, and the way Patrick matched the outside brickwork looks great. I know people are always ready to complain and not so ready to praise so I thought I would let you know what a good job I feel has been done. I now hope you get the job to do my Bay windows at the front of my house too!

May I take this opportunity to thank you for the efficient manner with which Premier Windows Ltd has conducted the work at our house recently. Your workforce, (led by Jason) has demonstrated considerable skill, in completing a task that was not simple, by any means. The work was carried out in a highly professional manner and this is reflected in the standard of the installation of the windows. Your company was verbally recommended to me by acquaintances in the neighbourhood, I shall have no problem in making similar recommendations to others.
