Rob Wozniak moved into a c. 1850 commercial building in downtown Easton, PA, in 1999. The facade of the building had been "shell pointed" with a hard Portland cement mortar, causing extensive damage to the bricks.
Unaware of the differences between lime mortar and cement mortar, Rob discovered most brick & stone buildings built prior to the end of WWII were constructed with lime-based mortar that's compatible with old softer bricks, allowing them to "breathe" (expand and contract with temperature and humidity) - but those older bricks are incompatible with cement-based mortars, which would hold water in the wall and eventually cause extensive efflorescence and spalling damage to the bricks.

Preservations Works is incredibly knowledgable about restoring historic homes and businesses. They use historically appropriate masonry restoration, custom plaster materials and application of those materials. Their custom plaster work is hands down incredibly artistic and they can create exact replicas of historic plaster work. I would recommend them for any masonry and or plaster work.
