Factors That Influence Siding Installation Costs in Ottawa
1. Material Selection (The #1 Cost Driver)
Your siding material choice can double—or triple—the final cost. Vinyl remains the most budget-friendly option, while metal and fiber cement deliver premium durability, especially in Ottawa’s freeze-thaw cycles.
To compare lifespans and durability rankings, many homeowners use resources like:

2. Home Size & Layout Complexity
Total square footage is only the first part. Builders also assess:
- Gables
- Dormers
- Number of windows & doors
- Two-storey installation premiums
- Roof tie-ins
- Drip cap & flashing needs
A simple single-storey Barrhaven bungalow may cost thousands less than a multi-roofline Orleans home.
3. Removal of Old Siding
Removal fees in Ottawa range from $1.50 – $4.00 per sq. ft.
Factors affecting removal include:
- Presence of asbestos-based siding
- Rot, mold, or hidden damage
- Old aluminum that requires special disposal
For a 1,800 sq. ft. home, removal alone can add $3,000 – $7,000.
4. Insulation & Energy Efficiency Upgrades
New Ontario energy standards (referenced by the Government of Canada’s energy efficiency guidelines) are pushing homeowners toward insulated siding, high-performance house wraps, and rainscreens.
Add-ons include:
- Exterior rigid foam board
- Insulated vinyl siding
- Rainscreen drainage gap systems
- High-performance house wrap
- Flashing and waterproofing updates
These upgrades add $3–$8 per sq. ft. but can reduce winter heat loss significantly.
