Just what a professional service should be. Nothing but the best experience from the moment I clicked on the SF website. The multipoint lock failed in the locked position on our double glazed front door. I was expecting a huge bill to repair, or even a new door. SF came round within 2 hrs. Opened the door without any damage to door or surrounding trim and fitted a new lock. Professional, honest and altogether pleasant service. Businesses like this deserve to do well! 5 stars – Although deserves 6
