How much does a Siding Installer cost in Montreal in 2026?

What's Involved

Siding replacement involves removing the existing exterior cladding, inspecting the sheathing and house wrap underneath, making any necessary repairs, installing new weather-resistant barrier (WRB) if needed, and applying the new siding material. The project also includes finishing around windows, doors, corners, and soffits with matching trim.

In Canada, siding must withstand extreme temperature swings, UV exposure, wind-driven rain, and in many regions, ice and snow loads. The most common materials are vinyl (dominant in Eastern Canada), fibre cement (e.g., James Hardie), engineered wood (e.g., LP SmartSide), and traditional wood clapboard or shingles.

For homes in Montreal, choosing a siding material rated for your climate zone is essential. Proper installation over a rain screen or house wrap ensures moisture management and helps prevent mould and rot in the wall cavity.

Factors That Affect Cost

• Material — Vinyl ($5-$9/sq ft installed) vs. fibre cement ($9-$15/sq ft) vs. engineered wood ($8-$13/sq ft) vs. natural wood ($10-$20/sq ft).
• Home size — A typical 1,500 sq ft home has 1,200-1,800 sq ft of exterior wall area.
• Removal and disposal — Stripping old siding adds $1-$3/sq ft.
• Sheathing repairs — Rotted or damaged OSB/plywood needs replacement at $3-$6/sq ft.
• Architectural details — Gables, dormers, bay windows, and multiple corners increase labour time.
• Insulation upgrades — Adding rigid foam board under new siding costs $2-$4/sq ft but improves energy efficiency.
• Permits — Some municipalities in Montreal require permits for siding replacement, especially if changing materials.

How to Save Money

1. Choose vinyl siding for the best value — it's durable, low-maintenance, and the most affordable option.
2. Combine siding replacement with window or insulation upgrades to reduce scaffolding and mobilization costs.
3. Get three quotes from siding contractors in Montreal and compare material grade, warranty, and trim details.
4. Ask about manufacturer promotions or contractor volume discounts on materials.
5. Apply for energy rebates if adding insulated siding or continuous insulation under the cladding.

Hiring Tips

1. Verify the contractor has experience with your chosen material — fibre cement and wood require different skills than vinyl.
2. Ensure they carry liability insurance and WSIB/WCB coverage.
3. Ask about their moisture management approach: house wrap, rain screen, and proper flashing around windows.
4. Get a written quote that specifies material brand and product line, trim details, and waste disposal.
5. Check references from recent siding projects in Montreal and inspect the finished trim work in person.
