Smart Gutter USA. I had the gutter guards installed on the front of our home last summer (we had the rear completed the prior year). The Tech (Sonny) indicated that +/- 8' of the gutter on the left side of my home needed a wider guard that he did not have on hand. He installed the "standard" section and promised to return when he could get hold of the wider sections. I have sent two-2 emails to the company and have not heard a thing. Not the best customer service.
