They were the last company to come for an estimate. He inspected my gutters and came down with a wad of plastic wrapping and a few pieces of shingle, and said that was causing my problem. He said that if I continued having a problem he would install an additional downspout for $50 and did not charge me for the visit.
Leaf Filter Gutter Protection gave me an estimate for $1,164 to clean my gutters (ridiculous!).
Space Coast Rain Gutters never showed up and when I called the company nobody answered. A few days later I found a business card from them saying he had been held back and to call again.
If I have another issue, I will definitely call A-1.
