Hands on

"I've personally completed every scope in Division 7. General contractors appreciate our submittal process because they are highly detailed and always on time"

Right out of high school Corey Roberge had the opportunity of a lifetime to travel across country. 


Arriving at this destination and looking for work before the age of cell phones, he was given maps, materials, and a truck and directed to the jobsite that would cement his career in one of the most critical phases of commercial construction.

Corey is an eyes-on-site commercial subcontractor that will be there for every step of the waterproofing and firestopping phase of your project to monitor schedule, quality and budget!
