What is ashlar masonry?

Ashlar masonry uses stone that has been dressed (shaped and smoothed) into regular rectangular or square blocks, then laid in straight horizontal courses with tight, consistent joints. The result is a flat, orderly wall face with a finished appearance, unlike the rough and irregular surface of rubble stonework.

The precision of ashlar work lies in both the stone cutting and the laying process. Each block must fit snugly against its neighbors, and mortar joints remain thin and uniform. This requires skilled labor and careful selection of stone, which is why ashlar typically commands higher cost than rougher masonry methods.

Ashlar comes in several patterns. Coursed ashlar arranges stones in level rows of equal height. Random ashlar uses stones of varying sizes but still maintains a dressed, squared appearance and level courses. Both contrast sharply with random rubble masonry, where uncut or minimally shaped stones are laid without regard to pattern.

Connecticut contractors use ashlar for visible masonry walls, foundations, and restoration work where appearance and durability matter. The tight joints and dressed surfaces shed water effectively and resist weathering better than rough masonry. Ashlar also provides a formal, professional look valued in both historic renovation and new construction.
