Jason from Zenith's Kent branch visited to discuss replacing existing double glazing for new units. He was very friendly and knowledgeable and went to great lengths to explain the technology behind the glazing products and the benefits behind them. It was a very comfortable meeting and in no way did we feel under any pressure. As this was out first meeting, I intend to write further about how the installation went and our level of satisfaction, but, suffice to say, it was a very promising and impressive start to the project.
