We firstly met with James , Sales Executive who had a comprehensive knowledge of all the DWL products and was able to advise us competently of the equipment we would require. More importantly DWL were very accommodating and supportive in fitting in with our schedule. Dan the Co-ordinator was a key person in this undertaking. From the surveyors who came, and the installers. We must say the guys all turned up punctually on each occasion, and executed their tasks with skill and dexterity to a very high standard. It has been a real pleasure to deal with DWL and both the picture window and doors look spectacular. We would have no qualms in recommending this company to anyone else we know in the future.
