Kingston Armoury
Building Envelope
RTM completed comprehensive building envelope restoration work at the Kingston Armoury, a federal institutional heritage building located at 100 Montreal Street in Kingston, Ontario. The completed project restored key architectural elements and improved long-term performance while strictly preserving historic character.
Project Scope
RTM completed building envelope restoration work at the Kingston Armoury, including heritage masonry restoration, stone repairs, roof and flashing work, wood window restoration, selective demolition, and coordination of related building services and site work.
The work included repairs to the entrance tower, exterior stair areas, stone masonry elevations, roof assemblies, and existing wood windows. The masonry scope included repointing existing stone joints, rebuilding and stabilizing stone masonry, stone patching, stone replacement, crack injection, and heritage masonry reinforcement.
Notable Details
This project required careful work on a historically significant federal building while preserving existing materials, surfaces, and finishes. The specifications placed particular importance on protecting historic fabric, salvaging materials where required, and using careful selective demolition practices.
The drawings identified restoration and reinstallation of existing wood windows, including the removal and reinstallation of metal security bars, new hinge and latch connections, and related masonry repairs at openings.
The masonry work included complex tower parapet repairs, the rebuilding of upper wall areas, deep repointing with traditional lime-based mortar, stone stabilization, and the careful reinstallation and pinning of crenellation stones using stainless steel anchorage.
Final Result
The completed work successfully restored and stabilized key exterior envelope elements of the Kingston Armoury while rigorously maintaining the historic character of the building.
The project significantly improved the long-term performance of the masonry, roof, drainage, and window assemblies, establishing a weather-tight structural envelope that respects the original architecture of this prominent federal heritage property.
