ince its founding in 1849 by coppersmith John Nicholson, our firm has grown from a small roofing and waterproofing concern to a modern company with sophisticated restoration contracting capability. Our firm successfully meets the needs of building owners and architects for craftmanship in all types of exterior repair and restoration work, including roofing, waterproofing, masonry and concrete restoration, and sheet metal fabrication for both historic and comtemporary structures.

As a full-service company, we offer clients total management of a project from inspection, budget preparation, and bids to performance of all work and coordination of relevant trades. We have architects and engineers on staff whose knowledge of building structure, facades, and materials adds to our understanding of a client's problem, enabling us to respond to their needs quickly and efficiently. To complement this professional expertise, we employ experienced craftsmen – many of whom have been with the company for more than thirty years. These valued workmen bring insights that can only be developed through a lifetime on the job.
