Toronto & GTA · Long-Term Protection
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.

Wood siding offers a natural, high-end look that works across both modern and traditional homes.
We install wood siding that holds its shape and appearance through seasonal movement.

Modern & Durable
Metal siding is a durable, low-maintenance option with a clean, modern look.
“Metal siding requires accuracy. Small errors show immediately. We build it clean and exact.”
Full System Design
Cladding is more than just the outer layer; it’s a full system designed to protect the structure underneath.

We design cladding systems based on your home, not a one-size-fits-all approach.
Full Replacement
If your siding is failing, replacing it properly is critical to avoid deeper structural issues.
“Replacing siding isn’t just cosmetic. It’s an opportunity to fix what’s underneath.”
