D.J. Cross has more certified technicians on staff than any other company in the Philadelphia region.
In almost forty years, D.J. Cross has served nearly 35,000 families and businesses (34,397 to be exact). Experience not only means time under your belt and customers served, but also the certifications necessary to master the craft. D.J. Cross continues to invest in educating our technicians from industry leaders. In fact, D.J. Cross was one of the first businesses to become a member of the National Chimney Sweep Guild. The Guild is the premier, non-profit trade association that promotes professionalism and ethical accountability in the chimney and fireplace industry.
The top two chimney certification agencies are: the Chimney Safety Institute of America (CSIA.org) and the National Fireplace Institute (NFI.org). These agencies are responsible for teaching America’s chimney and fireplace technicians to inspect, maintain, and restore your hearth. All lead technicians at D.J. Cross are certified by these organizations.
Our lead duct technicians are certified by the National Air Duct Cleaning Association (NADCA.com), which is the hallmark certification for specialists in HVAC air systems. While D.J. Cross started the business focusing on chimney cleaning and restoration, in the 1990s we expanded our services to include the maintenance of home heating and cooling ducts.
