Problem Solved, Happy Customer and a Fulfilling Day at Storm

Our involvement several months ago started with my wife having an idea to use a copper sheet as a backsplash that could hide a circuit breaker box and could slide in and out allowing access to the box. She called Storm Copper and met Tina Hicks. Tina went out of her way to help including sending several samples of different patterns on the sheeting. She was impressed with the service as well as the friendly attitude. She commented to me at the time what a positive experience she had in her conversation with Tina and how she did everything she said she would and quickly.
We ended up buying a sheet which looked great until I sprayed on the protective coating. I will spare you the details but I spoke to Tina, explained the problem and the procedure I followed per Storm Copper instructions and sent some pictures. The short story is that the sheet was replaced pre-sprayed at no cost to me. I installed it behind the sink and it looks great. Not only was the outcome perfect but the whole process was a pleasant one thanks to Tina.
Although Tina is the most memorable, I did have occasion to speak to some other Storm Copper people prior to placing the original order and they were also easy to deal with and very pleasant. My compliments to whoever does the hiring as well as the environment that exists to encourage people to make the customer truly feel like a customer.
If you ever need a testimonial to what a great company Storm Copper is, feel free to contact me.
Take care,
