About
A framing crew built on doing it right and on time
Dos Santos Construction LLC is a commercial subcontractor based in Kenilworth, NJ, working across New York and New Jersey.
Who we are
Led by Wellington Dos Santos
Wellington Dos Santos has spent more than 20 years framing commercial buildings across New York and New Jersey. He runs every Dos Santos Construction crew around two things: work done right the first time, and a schedule the general contractor can count on.
We work for general contractors, developers and building owners on commercial, mixed-use and multifamily projects. Our crews install structural steel and metal deck, bar joists and C-joists, panelized load-bearing walls, light and heavy gauge metal framing, composite floor systems such as Hambro, EcoSpan, ComSlab and Epicore, and ACT suspended ceilings.
After more than 20 years in the field, what we are judged on has not changed: the quality of the work we leave behind and whether we finished it when we said we would. Everything about how we run a job is built around those two things.

Quality work
Walls plumb and on line, joists at spacing, deck fastened to the pattern, grid level. Getting it right the first time is what keeps the next trade moving and the punch list short.
On schedule
We plan crew size, deliveries and crane days around your schedule and keep you informed about what is done, what is waiting on information and what the next floor needs.
