Built in 1911, the Jesup Memorial Library is one of Bar Harbor’s most cherished historic structures. Beset by the coastal environment, the building, envelope, and site require localized, ongoing maintenance. To create a comprehensive strategy to ensure the landmark’s lasting future, maintenance records were reviewed, current conditions were carefully assessed, and outstanding issues were cataloged. A multi-year effort to preserve the building’s architectural integrity was launched to sew together the needs of both site and building. The Jesup Memorial Library stands as a vital community cornerstone, and its preservation is designed to provide a durable public resource that will serve generations of Bar Harbor residents still to come.
Key Highlights
- Historic masonry preservation: The project began with targeted diagnostic evaluations, unlocking possibilities that cleared the way for widespread repointing, structural brick-and-stone rebuilding, and meticulous stabilization of historic masonry.
- Watertight infrastructure: The envelope strategy integrates a rebuilt semi-annual granite entrance foundation, injection-grouting of foundation walls, new perimeter drainage, slate roof repairs, and custom copperwork for downspouts and perimeter detailing.
- Specialized shell solutions: The multi-faceted scope tackled complex challenges, including skylight restoration, precise waterproofing, and thorough leak mitigation across the building envelope.
- Site-specific integration: Upgrades extended beyond the primary structure to manage the careful repair of historic retaining walls and paving at the building’s main entrances.
- Community collaboration: Working in close coordination with library leadership and community volunteers, the team ensured every detail, from custom copper flashing to intricate masonry joints, met the highest standards of historic preservation.
