We had a basic iron security door purchased and installed within about 3.5 weeks from purchase. I was not happy with the initial installation. There were holes in the seal in multiple places. The closer restricted the door from actually opening which prevented us from being able to enter our home with our stroller. The solution to this problem suggested by installer was to disable the closer. I presented all of these issues to the installer who came initially and he had no solutions.
So I subsequently called customer service and initially they were going to send same installer but I explained I knew he did not have any solutions as I discussed all of these issues with him. Therefore, I requested someone different. They sent Adam who came about 2 weeks later. He was worth the wait. He fixed ALL of the issues we were having. The closer bracket was installed in a more optimal position, the door closes seamlessly, the seal is fixed. I was very impressed with his professionalism and his work. In the end, I am 100% satisfied but it took vigilance and extra effort on my part to reach this satisfaction. The company did deliver in the end.
