A PRECISION STRUCTURAL TRADE PARTNER.

ICI & BUSINESSES.

Precision Construction for Professionals Who Demand Accuracy.

Monolith Custom Construction Inc. will partner with builders, developers, architects, engineers, and commercial clients who require precision execution, structural reliability, and professional accountability.

We provide concrete, structural carpentry, and accessory structure services for projects where tolerances matter, drawings must be followed, and long-term performance is non-negotiable. Our goal is simple: execute your scope accurately, reduce risk, and eliminate unnecessary callbacks or delays.

Based in King City, we serve the Greater Toronto Area, Simcoe County, and Central Ontario, including Muskoka.

  • We specialize in concrete applications where accuracy, load performance, and durability are critical.

    • Carports and covered work areas

    • Barns and agricultural buildings
