We had about $600 worth of gutters installed on our house in Jan 03. I didn't see them but my wasn't impressed with the skill or courtesy of the installers. By April both long (~50 foot) runs down the side had developed creases in the middle of the runs, it looked like the metal had just popped out. I called them back as they gave a 1 year warranty. My wife said they accused us of pulling on them! Eventually they just nailed the centers down, saying we better do it right cause otherwise they'll call us back! It looks pretty crappy now, but I don't want to deal with them again. I wish I had gone with one of the other bids, and spent $50 more, those guys seemed a lot nicer.
