Report
Diamond Windows have done a fantastic job on our house. We called up for a quote (in the middle of a snowstorm) and Mike came to measure up a few hours later. He was very friendly and helpful. He produced a quote the following day. There was no messing about like some companies where they start at a high price and you have to haggle to get it low! The price was competitive and fair. We'd asked friends for recommendations and Diamond came highly recommended.
The installation took a couple of days, the installers were polite, friendly and tidy workers. The finished job has transformed the look of our home. The quality of the windows is excellent too. Many thanks for a great job!
