One team. Every building service. Across the GTA.

Why Master exists

Property managers in Toronto and the GTA spend more time coordinating vendors than managing buildings. A typical portfolio requires a window cleaner, a janitorial company, a painting contractor, a pressure washer, a floor care crew, and a maintenance team — each with its own COI, its own WSIB clearance, its own scheduling window, and its own invoice. When something falls through, everyone points at the other vendor.

Master Building Services was built to eliminate that problem. One master service agreement covers the entire building — interior and exterior, routine and urgent — under one accountable team. One COI. One WSIB clearance. One monthly invoice. One point of contact who knows your property. Photo-verified completion on every visit, forwarded straight to your board.

Credentials and insurance

Every Master technician working at elevation is Working at Heights trained. Crews are fully WSIB-cleared and the company carries full liability insurance — $5M per occurrence — so your building and your board are protected on every visit, every time. Every completed service is photo-documented, giving you an audit trail you can forward to ownership or compliance reviewers without reformatting.

Certificates of insurance and WSIB clearance are available on request — included automatically when you sign a master service agreement.

How we work

Every quote is delivered within 48 hours — guaranteed. General inquiries receive a response within 2 business hours. No voicemail loops, no waiting a week for a call back. Master contracts are flat-rate and multi-year, with no annual CPI escalators and no surprise extras buried in a renewal — the price you sign is the price you keep.

After every service visit, a photo-verified completion report is sent directly to you. For caulking and inspection work, that means before/after documentation. For janitorial, it means a checklist verified line by line. Every visit is accountable, by design.
