In 1998, Jam Arch came to life in Upper Montclair, NJ with a focus in building a client base and a good reputation. Our work previously consisted mainly of residential additions and alterations. In the summer of that year Justin hired his first employee, expanding the staff to ten over the next 9 years. Since that time, we have completed over 800 projects in the residential, commercial, institutional, childcare and religious building industries, totaling more than $75 million in construction.
