Joff did an excellent job replacing an old plastic gutter for us with new seamless gutter and downspout. His crew regularly works in Bangor with no issue on traveling from Palmyra. They use 0.032 inch aluminum for their seamless gutter (the thickest aluminum used in gutter work, and the best for Maine winter weather). He used clear silicone caulk - the best you can get for longevity. He sealed not just the corner joints, but also the entire length of the gutter to our facia board under the drip-edge, and showed a lot of attention to detail. They also did a nice job using gutter guard that I had already purchased and they were careful cleaning up after the job. When they arrived to do the job, we asked for an additional item that was not on our original job quote (replacing an additional downspout that had not been in the original job quote) and he was fair and honest about the additional cost for doing that work. (Note: A different seamless contractor from Bangor/Brewer had not been fair about an add-in we asked for after their initial quote, and then tried to pack on additional costs for minor items). Joff even came back a couple days later to seal some holes in our siding from our old gutter brackets that we noticed, and he then also re-fit a gutter guard for us -- free of charge. Overall his installation including several helpful detail items like providing an extra wide valley-diverter that was above and beyond what I think other gutter installers would do. So definitely a 5-star rating. read more
