Where Structure Meets Detail
In Toronto, your home is constantly exposed to moisture, temperature swings, and long winters. If the exterior carpentry isn’t built properly, it won’t last. If it isn’t designed properly, it won’t look right.

Serving Toronto & Greater Toronto Area
Foundation of Every Project
Everything starts with the structure.
Exterior carpentry that lacks proper framing will fail quickly, no matter how good it looks, especially in Toronto’s climate. We build structural wood framing that holds its integrity through seasonal movement, not just something that passes inspection.
Built to Last
Defining the Look
Trim work defines the look of a home. It’s what gives clean lines, depth, and character to the exterior.
Whether it’s modern minimalist trim or detailed profiles, exterior trim carpentry by SZ Obsidian is crafted for lasting performance and visual appeal.
Function & Appearance
Soffit and fascia are often overlooked, but they play a major role in both function and appearance.
Why They Matter
Protect roof structure from moisture
Provide proper ventilation
Create clean roofline transitions
Substandard installation leads to risk of water damage and long-term structural issues. With SZ ObsidianBuilds, you get mindful installation - proper protection and a flawless finish.
Built for Durability
Exterior stairs take more abuse than almost any other structure.
Movement and Shifting
Over time due to ground movement
Rot from Moisture
Exposed to the elements year-round
Poor Footing & Support
Inadequate foundation for load
Solid Base and Footing
Proper foundation for long-term stability
Proper Rise/Run
For safety and comfort
Built for Long-Term Use
Framing that withstands Toronto’s climate
Whether it’s a front entry staircase or backyard access, we build stairs that stay safe, level, and structurally sound.

Framing Matters
The Foundation
A deck is only as good as the framing underneath.
Decks can look fine initially but fail structurally within a few years due to poor framing practices. Our focus on the structural phase ensures that your deck doesn’t just look good, it lasts.
Where Craftsmanship Shows
We build custom exterior woodwork that ranges from clean, modern design to highly detailed restoration work.
Modern Exterior Carpentry
Many homes in Toronto were built with intricate woodwork that has been lost over time. We restore that detail by:
Restoration isn't guesswork.
Historical Knowledge
Understanding historical construction methods
Complex Recreation
Recreating complex shapes and curves
Respect
Respecting the original architecture
“We’ve restored homes to bring back 100-year-old designs that had been removed or damaged. If the original detail exists, we can rebuild it.”
We don’t “replace” — we bring the original look back to life.
Know the Problem
Most problems start at installation, not years later.
We build with Toronto conditions in mind from the start.
