Solving New Jersey's most complex structural challenges since 1989

We're not a general contractor that does a little bit of everything. We're structural framing specialists — the team other contractors call when the job requires real expertise. LVL and PSL engineered beam installation, load-bearing wall removal, foundation repair, internal home expansions, and custom outdoor structures. If it's structural, it's what we do best.

Founded by Vincent Castellano and built entirely on referrals and repeat clients, CDI Builders has spent over 35 years earning a reputation for precision work, straight talk, and jobs that pass inspection the first time. We guide every client through the full process — from prints to permits, site work to completion — so nothing falls through the cracks.

Licensed and insured throughout New Jersey. Based in Hillsborough. Proudly serving Central NJ.
