More Details About Project The vast majority of the work that DEC perfoms is custom made to the architect's design. Many times, we are askd to do the more difficult work as a result. On this project, we supplied the door surrounds and pediments when the structural column manufacturer balked at the parts. We matched their color and cast these to in a one-piece configuration. Since this was Echo-Stone, we were able to produce these elements quickly and accurately with a very consistent finish.
