Dedicated and experienced experts

The NBC team has a depth of expertise and problem-solving skills. Unique in the industry, more than half of our project managers and superintendents have been with us for decades.

 

Most of our technicians have been on the crew for at least twenty years, several over thirty. Their collective knowledge has proven invaluable, particularly when formidable problems have appeared, such as an unexplained leak source, complicated structural factors, or delicate architectural elements in need of restoration. Even on more routine jobs, our crews achieve impressive efficiency and superior results because they know each other—and work together—so well.
