What Does Siding Replacement Cost?
Siding replacement costs in Ontario typically range from $5,000 to $15,000 for a standard home, depending on the material, home size, and complexity of the job. Partial replacements (repairing or replacing just a section) can cost considerably less.
Average Costs by Material
| Material | Cost Per Sq Ft (Installed) | Typical Home Total |
|---|---|---|
| Vinyl siding | $4 - $7 | $5,000 - $10,000 |
| Aluminum siding | $5 - $9 | $7,000 - $13,000 |
| Engineered wood | $8 - $14 | $10,000 - $18,000 |
| Metal panel siding | $7 - $12 | $9,000 - $16,000 |
These are ballpark figures. The actual cost depends on your home’s size, the number of openings (windows and doors), and any underlying repairs needed.
Choosing the Right Material
Vinyl Siding
The most popular choice in the GTA for good reason. Modern vinyl siding is durable, low-maintenance, and available in a wide range of colours and profiles. It doesn’t need painting, won’t rot, and handles Ontario’s climate well.
We install vinyl siding from Kaycan and Gentek, Canadian manufacturers whose products are designed for our freeze-thaw cycles.
Aluminum Siding
More durable than vinyl, aluminum handles impacts better and doesn’t warp in extreme heat. It’s a strong choice for homes in areas with heavy weather exposure. The downside is a slightly higher cost and the potential for denting.
Insulated Siding
Both vinyl and aluminum siding are available in insulated versions, where a layer of foam backing is bonded to the panel. This improves your home’s energy efficiency, reduces outside noise, and makes the siding feel more substantial.
The added cost is typically $1 to $2 per square foot, but many homeowners find the energy savings and comfort improvement worth it.
Signs Your Siding Needs Replacement
You might not need a full replacement. Here’s how to tell:
Watch for these signs:
- Cracked, warped, or buckled panels
- Fading that won’t clean up
- Soft spots when you press on the surface
- Mould or mildew that keeps coming back
- Loose or missing panels after storms
- Higher than expected heating bills
A section repair may be enough if:
- The damage is limited to one wall or area
- The rest of the siding is in good shape
- The issue is from a specific event (storm, impact)
Full replacement makes sense when:
- Multiple walls show deterioration
- The siding is more than 25 years old
- You’re seeing moisture damage to the sheathing underneath
What to Look for in a Siding Contractor
- Licensed and insured. Ask for proof of WSIB coverage.
- On-site assessment. No reputable contractor quotes siding without seeing your home.
- Clear scope of work. The quote should detail materials, removal, disposal, and any trim work.
- Manufacturer partnerships. Contractors who work with specific manufacturers typically have more experience with their products.
- References available. A good contractor has a track record you can verify.
The Connection to Your Other Exterior Components
Siding doesn’t exist in isolation. When we replace siding, we always check the condition of your soffit, fascia, and flashing. These components work together to protect your home, and addressing them at the same time is often more cost-effective than doing separate projects.
If your eavestroughs, soffit, or fascia also need attention, we can handle everything as one project, saving you time and reducing the total cost.
