From the online application which I completed vie Facebook to the windows being fitted took only 5 weeks. From the initial measuring and free quotation to the guys that fitted the windows everyone was very polite and had a good senses of humour, windows were fitted in one day. I also received £200 per old window and a returning customer discount. The windows that they fit look great and you really notice the difference especially with the free coulor frame upgrade. I have used safe style when I had doors replaced and the quality and professionalism is second to none, I would very much recommend to anyone to use this company if you are thinking of replacing doors or windows
