Aman is the Arabic word for safety. Mahmoud chose it on purpose, because a contractor is not really selling tile or paint. He is selling the feeling that you can stop checking on the work.
Mahmoud Thiab has spent ten years with tools in his hands. He learned the trade in Palestine, on homes where the standard was simple and the work was judged by the people who had to live with it.
Aman Construction & Remodeling is his company. He does the walkthrough, he writes the estimate, and he is the one on site doing the work. When a project needs more hands, he brings in help he trusts and he stays on the job. You will not get passed off to a crew you have never met, and you will not be chasing anyone for an answer.
