Siding Installation & Exterior Cladding in Toronto

Your Home's First Line of Defense

In Toronto, siding takes constant abuse from moisture, wind, and freeze-thaw cycles. If it’s installed incorrectly or built with the wrong materials, it won’t last.

At SZ Obsidian Builds, we approach siding the same way we approach all exterior work: structure first, finish second. The goal isn’t just to improve appearance — it’s to protect the building envelope long-term.
