PVC, WPC, and composite siding systems represent the highest tier of modern exterior claddingโdesigned for homeowners and builders who prioritize performance, precision, and long-term value. Unlike traditional siding materials, these advanced composites deliver exceptional durability, refined aesthetics, and minimal maintenance, making them ideal for custom homes and high-end renovations across the Greater Toronto Area.
Every installation begins with a detailed assessment of the homeโs structure, design intent, and exposure conditions. Alliance Exteriors Inc. carefully prepares the substrate, installs appropriate weather barriers, and applies composite siding systems according to manufacturer specifications. Precision fastening, expansion allowances, and clean detailing ensure long-term stability, performance, and a flawless finished appearance.
In addition to PVC and WPC composite siding, we install James Hardie fiber cement siding, premium wood siding, modern metal cladding, custom exterior cladding systems, self-adhered weather barriers, and soffit and fascia systems.
