These price ranges include material, labour, trim work, and disposal of old siding. Actual costs may vary depending on architectural complexity, number of stories, and site conditions.
Additional Factors That Influence Siding Costs
1. Removal of Old Siding
Tearing off old siding typically adds $1 – $3 per sq. ft. to project costs. Homes with multiple layers (e.g., old wood plus vinyl) may require additional labour.
2. Insulation & House Wrap
Adding insulated panels or modern house wraps behind siding improves thermal performance but adds $1.50 – $4 per sq. ft. This upgrade often qualifies for energy efficiency rebates through programs like Natural Resources Canada’s Home Efficiency Rebate Plus.
3. Trim, Soffit, and Fascia
Professional trim work enhances appearance and prevents moisture intrusion. This can add $1,500 – $4,000 for an average Ottawa home, depending on materials and complexity.
4. Architectural Features
Dormers, gables, bay windows, and multi-story elevations increase installation complexity. Expect a 10–25% increase for homes with these features.

Seasonal Pricing Trends in Ottawa

Winter installations are possible but require specialized techniques to prevent cracking and ensure proper adhesion. See Winter Siding Installation in Ottawa: Myths, Risks, and When It’s Fine for expert insights.
DIY vs. Professional Installation Costs
While DIY siding installation might seem like a way to cut costs, Ottawa’s extreme weather, strict building codes, and the need for precise waterproofing make professional installation the smarter long-term investment.
- DIY Material Costs: $4 – $14 per sq. ft. (vinyl or basic wood)
- Professional Costs: $9 – $30+ per sq. ft., but includes warranty, labour, and compliance

Permits and Building Code Considerations
In Ottawa, siding replacement may require permits if structural changes are involved or if your home is part of a heritage district. You can verify requirements through the City of Ottawa Building Permits Portal. Non-compliance can lead to costly delays or fines.
Energy Efficiency and Resale Value
Siding replacement isn’t just cosmetic. It can deliver tangible energy savings during Ottawa’s cold winters and boost resale value significantly. Modern insulated siding can reduce heating costs by up to 15% annually, while fresh siding improves curb appeal and appraisal value.

Choosing the Right Siding Contractor
Selecting a reliable contractor is as important as choosing the right material. Look for:
- WSIB & liability insurance
- Detailed written quotes
- Experience with Ottawa’s building code and climate
- Portfolio of completed local projects
Conclusion: Plan Strategically for 2025
Siding costs in Ottawa vary widely based on material, house size, and project complexity, but strategic planning can help homeowners maximize their investment. By understanding real price ranges and factoring in energy savings, design goals, and installation timelines, Ottawa homeowners can make confident, budget-smart decisions.
