"I don't usually write letters to any suppliers"
“I don’t usually write letters to any suppliers of goods and services. However in the instance I feel it is time to do so. I am agreeably please and surprised at the quality of both the windows and of your fitters. Your workers arrived on time on the agreed day and they were friendly and informative. When I watched them now and again while they were working, I noticed a very high standard of work was being done, and with a meticulous attention to detail. The work was complete within the time specified and no damage done to any of my property and the work areas were cleaned up each day. The quality of your windows looked better and had better fittings than the original ones, also the soun?proofing is much better. All in all the windows are excellent and your fitting team are a credit to you. If I ever decide to replace any more I will have no hesitation returning to you. ”
