Salvaged Puddingstone for Renovation

Roxbury Puddingstone is a beautiful conglomerate stone originally sourced in downtown neighborhoods of Boston and Brookline and pretty much nowhere else. It was extensively used in construction in the late 19th century, but there remains no longer any commercial source for this important building stone. Much no doubt remains in the ground, but the neighborhoods that produced it are now fully built out urban neighborhoods in which it is no longer possible to blast and quarry.

So where are we to get suitable Roxbury Puddingstone for building restoration and renovation? Salvaged stone from demolition is pretty much the only resource available today. S + H has a policy of keeping any historic building material acquired by demolition, in case of future need, but sometimes the volume needed requires us to seek an outside vendor.

An example is the expansion of a porch area on a Tudor Revival style home on Brattle Street. The walls of the porch were constructed out of puddingstone and capped with Portland (CT) Brownstone. We had a sufficient quantity of salvaged brownstone, which we cut to size. We located a quantity of puddingstone boulders produced by demolition of a ledge for a residential construction project in Brookline.

Le Masurier Granite, a granite supplier in Chelmsford, split the puddingstone boulders into the building units that we needed for the project. Freshly cut puddingstone is gray, not the mellow brown yellow that we associate with historic puddingstone. This yellow color is a result of the oxidation due to exposure to the elements. To match the existing historic stone color, Le Masurier “worked” the fresh cut stone with compressed oxygen to achieve the result that you see today.
