What John Canning does

John Canning & Co., Ltd. is a privately held, family-owned specialty architectural arts restoration contractor founded in 1975 and headquartered in Cheshire, Connecticut. The firm conserves, preserves, and restores historic decorative elements — ornamental plaster, decorative painting, gilding, woodwork, stone, murals, and fine art — across civic, sacred, higher-education, theatre, museum, and high-end residential buildings nationwide. Its service portfolio spans consulting and pre-construction (historic paint analysis, conditions assessments, plaster surveys, mockups), project and construction management (including complex scaffold engineering in occupied buildings), and full-scale restoration, with a proprietary Historic Plaster Conservation Services (HPCS) product line and a sub-brand, Canning Liturgical Arts, focused on sacred-space design. The firm has completed work on America's most recognizable landmarks — the US Capitol, Grand Central Terminal, Radio City Music Hall, multiple state capitols, Yale, Boston College, Boston Public Library, and the Mark Twain House — and adheres to American Institute for Conservation guidelines emphasizing reversible treatments and thorough documentation.

The company generates revenue primarily through project-based specialty contracting at fixed prices on specific restoration engagements, supplemented by professional-services fees for consulting, paint analysis, and pre-construction planning. Go-to-market is direct enterprise field sales — engaging building owners, architects (e.g., Connell Architects, KlingStubbins), preservation consultants, and general contractors (e.g., Wiseman Construction, Christman Company) through competitive bids and RFP responses on government, institutional, and private preservation projects. Bonding capacity is disclosed at up to $4M per single contract and $10.5M aggregate, which implicitly bounds project scale. Marketing is content-driven: an active blog, resource guides (including a free Theatre Restoration Guide), Instagram presence (~2,100 followers), newsletter, press releases, and frequent professional panels and presentations. Recent recognition includes the 2026 ICAA Addison Mizner Award (FL Chapter), 2025 Pennsylvania Historic Preservation Construction Award, 2025 Doris Duke Historic Preservation Award, and 2024 GSA Construction Awards Merit, reinforcing the firm's positioning as America's most renowned decorative arts studio.
