This is a great example of tuckpointing, in that it was done to what might be relegated today as an unworthy section of the house. Looking at the entire area of exposed stone it’s amazing that the time and effort would have been put into such a small area. With only a few square feet exposed directly to the street to be seen by pedestrians and much of the surface area exposed to the neighboring house, it exemplifies the perfection sought out by builders and the expectations owners had of craftsmanship.
What’s also great about this example is the cross section that can be seen on the exposed and worn corner, showing the beaded joint profile.
On a recent visit to Rochester, NY I noticed this gem of a building. While at first sight it may appear ordinary in its joint profile, further examination under the porch showed evidence of a well done tuckpoint joint, that has faded. there is also some evidence of a colorwash or stain that was applied to the brickwork and stopping mortar and has since faded. Alternatively this could be evidence that the red stopping mortar incorporated a red pigment which has almost completely faded. Only the proper sampling and examination of one of these mortar joints could offer some complete answer.
Also notice the pictures of a limestone foundation with a black beaded joint profile. This building is located behind the tuckpointed prick building. In fact you can see the rear of the building in the last photo.
