It took many return trips for them to get the job done close to correctly. They still haven't fixed a leaky gutter seam. I have given up on them ever doing that. The corner pieces of the siding are not correct at the bottom, the "flaps" just hang at a 45 degree angle to the ground instead of being neatly tucked. The vinyl siding is very prone to mold. Lastly, the siding makes tremendous amounts of noise in the house whenever the wind blows. Their installation crew performs very poor quality work. I would never hire them for anything again.
