As a company we have dept with door stop on and off over many years, we have seen many faults. Overall our view is that there door manufacturing facility is not nearly as high a quality as it needs to be. Our fitters dread fitting there doors. Our fitters basically need to rebuild each door on site to get them to work. On receiving doors into our premises we went through a stage of rejecting these doors approx 8 out of 10 for bad quality finish. When you speak to customer services you have to fight very hard for any help. We have moved away from this company, but fear that we will suffer more in the further as the quality of there doors gives up over our guarantee period. BE WARNED STAY AWAY!!!
