Mayfair House had undergone targeted repairs, as well as rehabilitation of one full elevation with a rainscreen assembly.   The roof assemblies varied from built-up flat roofs to sloped metal roofs.   Above-grade units were provided with balconies or decks.  The remedial work included replacement of:

• Exterior wall assemblies with stucco-clad drained cavity assembly at all face-sealed walls
• Windows and sliding doors with new thermally broken aluminum units
• Balcony and deck membranes complete with new guardrails and surface resloping
• Sheathing and deteriorated structural wood members, as required
• Built-up roof with two-ply modified bitumen SBS membrane
• Sloped metal roof with asphalt shingles
