Replacing my conservatory roof with your product was a considerable undertaking for me and my roofer who had not used the product before. Therefore I decided to visit you premises to check the light tiles out for myself and find out a little more about installation. I was greeted by Laura who was most helpful, answered all my questions and showed me some sample installations in you premises. From measurements and photographs I provided, Laura worked out a complete list of items required and provided a quotation.
In addition Laura emailed me with web links providing video clips of tile installation.
I was very pleased with the service and follow up emails. The tiles have arrived today as planned and I look forward to finding out how the installation goes over the next couple of weeks.
