Recently bought a house the ATR resided 5 years ago. One gable end has completely fallen off. I ve called multiple times to have someone come out at take a look to at it but have never received a call back. The work that was done was very unprofessional, they did a terrible job doing a layover (it s falling off in multiple places) and they used interior drywall screws to mount exterior light fixtures. At this point I just want to find out where they bought the nonamed siding from. No one at Harvey s, abc, Lowe s Home Depot, Coopman, National, Cape cod, Chace or Fernando Has ever seen the siding before.... but they where all in agreement they it was a hack job from the pictures ... be warned
