Dear Monica, I just wanted to say thank you to Magnetite; to yourself with our phone conversations re the product, and to the boys who installed the windows today. Although I wasn't there myself, I was told they were courteous, efficient and they left the rooms superbly tidy. Thank you again for your professional approach. In looking for retrofit double glazing, I approached a number of companies, but yours was the most professional- coming out to measure and quote- unlike many companies who want the client to measure and email the dimensions to them! The fact that Magnetite sent out a sales rep- Ken Seto (also very helpful, professional and courteous) to measure and quote was the main reason I went with your company, along with a recommendation from Philippe Goriaux from Acoustic. Customer service makes all the difference!
