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.
