About Us

Dunkirk Supply Inc. has been your community building materials dealer for over 35 years. We started out building trusses back in 1977 for Southern Maryland. Our design staff helps to make even the toughest jobs work. In 1983, we opened our first building materials store in Dunkirk, MD. We opened our second location in Lusby, MD, in 1990.

In 1999 we added our crane division, making us the one stop shop for all of your building needs.  Seeing a need for a building materials store in St. Mary's county, we opened our Leonardtown, MD location in 2004.
