We chose CMP to do our gutters because they had the best price and a family member had used them and said good things. They stuck to their quoted price, even though they were at our place a day or two longer than I think they anticipated. They had a tendency to start later in the day than I would have thought, around 9 or 10, so that could explain why it took longer. We have a lot of gutter on our house and wanted continuous black k-style. That's what we got, so no complaints there, however, the crimping on the ends of the gutters doesn't look very good as compared to our previous gutters and the seams at the corners don't look like other k-style gutters we've seen. It's as if they left one piece of the metal long to fold over the corner and screwed it into the other piece. Most others we've seen have an extra piece of metal seam sealed over the corners. The other issue I had is that even now, a month or so after the work was done, I am still finding little shards of metal around our house. We have dog so that's not ideal, not to mention if someone was walking around barefoot. Better clean up would be appreciated. read more
