CENTIMARK & EDWARD B. DUNLAP
SUCCESS STORY Edward B. Dunlap, Chairman & CEO
Edward B. Dunlap started D&B
Laboratories as a part-time industrial
cleaning products business in the
basement of his home in Pittsburgh,
PA, and then started Northern Chemical

business produced first-year sales
In response to customer needs, the company shifted from
product sales to installation, maintenance and repair of
commercial roofs and floors.
By 1974, sales reached $1 million. In March 1975, the official
company name was Consolidated Enterprises, Inc. - a holding
company for Northern Industrial Maintenance, Southern Industrial
Maintenance and Western Industrial Maintenance. The first sales
office outside Pittsburgh was established in 1976 in Harrisburg,
PA, as the company began its geographic expansion.

CentiMark’s President and COO).

by 1989. With geographic expansion,

and Western Industrial Maintenance
needed a common brand. Thus, the
company rebranded as CentiMark
Corporation in 1987.

of achieving $100 million in sales (which it achieved in
1994). “Mark” recognized the company’s unique mark on
and contributions to the roofing industry - all visions of
