What Jablonski Building Conservation does
Jablonski Building Conservation, Inc. (JBC) is a privately held, woman-owned architectural conservation firm founded in 1995 by Mary A. Jablonski and headquartered in Manhattan. The firm specializes in the preservation of historic buildings, monuments, sculpture, cemeteries, mosaics, bridges, and other cultural resources, and describes itself as among the nation's premier practices in this niche. JBC serves a horizontal mix of clients including architects, engineers, governmental agencies, cultural institutions, religious organizations, contractors, and building owners, with a marquee client roster that includes the Architect of the Capitol, the National Park Service, the Smithsonian Institution, the National Trust for Historic Preservation, the Metropolitan Transportation Administration, and universities such as Cornell and Yale.
The firm's offerings are organized around three phases — Assess (conditions assessments, materials analysis, paint analysis), Design (documentation, construction documents, field and lab testing), and Execute (conservation treatments, construction monitoring, materials sourcing) — supplemented by disaster preparedness and insurance evaluation services. JBC operates an in-house materials testing laboratory equipped with portable FTIR spectrometry and XRF analysis, with partner-laboratory access to petrographic analysis, SEM-EDS, GC-MS, and XRD. The firm also maintains an extensive proprietary library of material samples (sand, aggregates, tile, bricks, and stone from domestic and foreign quarries) and offers custom product development, including frost-proof tiles, for new construction matching historic materials. World-renowned architectural paint analysis is cited as a particular specialty.
Revenue is generated through project-based professional services engagements under multi-year contract structures, with fees determined by project scope, size, complexity, and client requirements. The go-to-market model is direct, relationship-driven enterprise/field sales to design professionals and institutional clients. Pricing is quote-based and not publicly disclosed. The firm employs 11-50 staff, all of whom hold graduate degrees from respected historic preservation programs, and is led by Mary Jablonski (President and Founder, adjunct professor at Columbia University since 2002), two Principals (Stephanie Hoagland and Helen Thomas-Haney), and two Senior Associates (Edward FitzGerald and Jennifer Kearney).
