Once an IT solution is successfully implemented we will not abandon you. At first we will conduct thorough training courses – either on-site at your premises or at our premises in Sendenhorst – and provide a professional customer service. Apart from their sound IT knowledge, our skilled staff will have a great deal of practical experience in the field of window construction and will offer quick and specific assistance should a problem arise. You can contact them between Monday and Thursday from 8am to 5pm and on Fridays from 8am to 12pm using our service hotline.
