I've worked as a construction project manager for over 30 years. I found Kevin to be knowledgeable, courteous, professional, diligent and very neat in the execution of his works. I had a reasonable idea of the specification the installation that I wanted however Kevin highlighted features within the equipment that I had made my mind up on that I was not aware of and persuaded me to go with a slightly less expensive option. Works were undertaken on time, to budget and to a very good quality. I am entirely happy with the quality of the installation and the equipment supplied and would not hesitiate to recommend I-Spy to both domestic and commercial clients.
