Chimney Crown Repairin Piscataway, Middlesex County, New Jersey, NJ
Chimney Crown Repair in Piscataway, Middlesex County, New Jersey, NJ. The chimney crown (also referred to as the chimney wash) is the top element of a masonry chimney. It covers and seals the top of the chimney from the flue liner to the chimney edge. The crown should provide a downward slope that will direct the water from the flue to the edge of the crown. The overhanging drip edge, by directing the run-off from the crown away from the chimney, helps prevent erosion of the brick and mortar in the chimney’s vertical surfaces.
