Tasha
South Harrison Twp, NJ
They did an amazing job building my deck. They went above and beyond the basic construction code to reinforce the deck due to its size and made sure that it remains safe and secure. I would not hesitate to use them again for my next project.
C Jam did great work. Mark was professional. He constantly kept me in the loop by texts, calls or emails. This was a much different experience than many other contractors who never let you knw what is going on.

Mark was extremely professional. Mark came to my home, took down my deck specifications. Within days, I received a highly reasonable estimate on a deck that I wanted built off the back of my house. The communication between Mark and myself, was exceptional. Marks work ethic is outstanding! Our deck is exactly how we envisioned it. Mark took the time to remove all of the construction debris, leaving my yard meticulously clean. I highly recommend C-Jam Construction LLC
