About the company
Jablonski Building Conservation, Inc., a women-owned small business based in New York, provides historic building conservation and architectural preservation services to federal agencies as a prime contractor on small-business set-aside purchase orders, with supplementary subcontract work on federal design-engineering projects. The firm is SBA certified as a Women-Owned Small Business and self-certified as a Small Disadvantaged Business, operating as a for-profit Subchapter S corporation and registered with the Department of Transportation as a certified disadvantaged business enterprise.
Jablonski's prime contract work centers on field conservation, conditions assessment, and historic-structure remediation — specifically stained-glass panel conservation, masonry analysis, and foundation documentation at historic properties. Named work includes a $57,232 purchase order from the National Park Service Northeast Region for stained-glass ceiling panel conservation at the exedra in Thomas Edison National Historical Park (Glenmont, New Jersey), a $54,910.03 order for exedra glass feature removal and reinstallation at the same park, and a $35,795 survey of the basement foundation wall at Thomas Edison National Historical Park (West Orange, New Jersey) including visual inspection, moisture testing, mortar and stone analysis, and preservation recommendations. All three prime awards carry Total Small Business set-aside designations and performance schedules running through March 2027 or October 2025.
The Department of the Interior's National Park Service Northeast Region dominates Jablonski's customer base, accounting for four awards with $178 thousand in combined potential value (67% of the firm's total portfolio value). The Department of the Army Corps of Engineers Engineering District New York represents three additional awards; together these two agencies cover 78% of all awards. Total portfolio activity spans nine awards since 2007, with recent trajectory showing two awards in 2026 and one each in 2024 and 2025 after a gap in 2021–2022. One award carries an ultimate completion date within the next twenty-four months (combined potential value $36 thousand).
Jablonski subcontracts to Jacobs/Ewingcole, A Joint Venture, on engineering design services; three sub-awards dated January 2024, March 2025, and February 2026 align with "100% RTA Design for Cullum & Lincoln Engineering Services." The firm operates without parent contracts, GWACs, or agency-wide IDIQs; all prime activity flows through direct purchase orders under small-business set-asides. Jablonski's geographic footprint for field work includes New Jersey and New York, with corporate headquarters in New York.
