Project Type

Balcony Repairs & Restoration

This balcony restoration project saw GroupCMG handling two properties for Osgoode Non-Profit Corporation (ONPHC), located at 2761 8th Line Road and 3200 Vance Street. The scope focused on addressing existing safety concerns, improving waterproofing performance, and extending the service life of the balcony assemblies while the buildings remained fully occupied.

Existing metal guardrails were mechanically cleaned to remove rust and failing coatings, prepared to a sound substrate, and repainted using an exterior-grade, corrosion-resistant system matched to existing finishes. Deteriorated top rails were removed, and replacements were installed to meet current building code requirements. A new traffic-bearing membrane system was also installed, including full surface preparation, priming, base coat, and topcoat.

Project Challenges

The balconies were experiencing advanced corrosion at the metal guardrails, including compromised anchorage that posed a safety risk to occupants. The buildings remained occupied throughout construction, and seasonal temperature considerations were at the centre of the project’s material selection and application to ensure performance.

Solutions Implemented

GroupCMG developed and executed a phased repair strategy to deliver the project in a more occupant-focused manner:

Planning & Coordination

Established a detailed plan to coordinate notices, access, and sequencing.
Maintained communication with residents to support a smooth workflow.

Phased Execution

Completed work in phases, providing uninterrupted unit and entrance access.
Implemented site protection and safety measures to address active hazards.

Technical Oversight & Quality Control

Selected materials and membrane systems suited for long-term durability.
Monitored temperature and curing requirements throughout the installation.
Coordinated with product manufacturers for procedures and on-site reviews.

Results

The structural concrete repairs restored the integrity of balcony slabs, while the new waterproofing systems protect against future infiltration and deterioration. These improvements, including the railing upgrades, enhance safety and visual appeal, lessen future maintenance demands, and support long-term lifecycle planning for both properties.
