Saint-Esprit-de-Rosemont Church

As part of the church restoration program, the stone cladding of the bell tower was dismantled to access the brick masonry behind it. With the masonry and mortar having reached the end of their useful life, our masons removed the bricks one by one and replaced them with new or restored bricks depending on their condition.

Damaged cladding stones were individually assessed: those with minor deterioration were repaired on site using natural stone dutchman repairs, while severely degraded elements were replaced with compatible new stones.

St-Marc stone was selected for the bell tower cladding due to its exceptional qualities and compatibility with the original masonry. Each element was precision-cut at our processing centre at Ducharme, with final adjustments made on-site as needed to ensure a perfect fit. The natural stone is distinguished by its exceptional resistance to freeze-thaw cycles, wear, and thermal variations. Its high thermal mass contributes to interior climate stability, while its low porosity once sealed limits future maintenance needs.

The installation of a system scaffolding was necessary to ensure the safe execution of work at height around the bell tower. The configuration represented a significant challenge, as the structure had to be installed on a sloped roof while wrapping around all four faces of the bell tower. A modular system was chosen to ensure precise adaptation to the building’s geometry. Anchoring and load distribution were carefully planned to preserve the roof’s integrity.
