Aging or undersized gutter systems on multi-unit properties create compounding costs and liability exposure that residential-grade solutions simply can’t address.
Built for Scale
THE CHALLENGE
What Property Managers Face Every Season
OUR APPROACH
A Complete Exterior Solution
We don’t just replace gutters — we assess, specify, and install systems designed around the actual drainage demands of your property.
Site Assessment & Scoping
We start with a full walkthrough of your property — measuring roofline square footage, counting drainage zones, identifying problem areas, and building a complete scope of work before any commitment is made.
No-cost for qualified properties
Lifecycle-Grade Gutter Installation
We fabricate and install seamless aluminum eavestroughs on-site using roll-forming equipment. No pre-cut sections, no leak-prone joints. Sized to the drainage load of your specific roofline — not the nearest standard size.

Before & After Galleries for Commercial Managed Properties
Blackstar Aluminum provides reliable exterior aluminum solutions for commercial buildings and property management clients across the GTA. This gallery highlights large-scale eavestrough, soffit, fascia, and siding projects completed on multi-unit residential buildings, warehouses, plazas, and office properties.
Our commercial projects are designed to meet functional drainage requirements while maintaining a professional appearance. With experience coordinating with property managers and contractors, we deliver consistent, code-compliant results on complex rooflines and large properties.
Multi-Unit Buildings
Blackstar Aluminum has worked with property managers, condo boards, and building owners across the GTA on projects ranging from 8-unit townhouse rows to large multi-residential complexes. We understand the operational realities — occupied buildings, tight scheduling windows, superintendent coordination, and the need for documentation that satisfies boards and ownership groups.

Warehouses & Industrial
Industrial rooflines move a lot of water fast, and standard residential gutters aren’t built for it. Blackstar Aluminum installs heavy-duty commercial eavestrough systems sized to the actual drainage load of large flat and low-slope roofs — with high-capacity downpipes and commercial-grade hangers rated for snow and ice loads. We’ve completed projects on warehouses, distribution centres, and manufacturing facilities across the GTA and Southern Ontario.

Retail & Plazas
Retail properties have zero tolerance for water intrusion, ice overhang over entrances, or visible exterior deterioration — and neither do their tenants. Blackstar Aluminum has installed and replaced eavestrough, fascia, soffit, and siding on plazas, drive-throughs, and strip malls throughout the GTA, working around business hours to keep disruption minimal and storefronts presentable throughout the project.

Churches & Institutional
Historic and institutional buildings often have complex rooflines, ornate fascia, and drainage challenges that require more care than a standard commercial job. Blackstar Aluminum has completed eavestrough and exterior work on churches, community centres, and institutional properties across Southern Ontario, matching profiles to existing architecture and sourcing materials suited to buildings that need to last generations — not just pass an inspection
