How Much Does Siding Cost in Ontario? A Straight Answer
Siding cost Ontario homeowners ask about more than almost anything else — usually within the first minute of a phone call. It’s a fair question, and homeowners deserve a straight answer rather than a vague “it depends.” Here’s an honest breakdown of what siding actually costs in Ontario in 2026, what drives the price up or down, and why the number you see online might not match the quote you get for your specific home.
Siding Cost Ontario: Pricing by Material
Pricing in Ontario is typically quoted per square foot installed. We install materials from trusted manufacturers including Kaycan, Mitten, and James Hardie. Here’s roughly where each material lands:
| Material | Cost Per Sq Ft (Installed) |
|---|---|
| Vinyl Siding | $6 – $14 |
| Metal Siding (Steel/Aluminum) | $8 – $16 |
| Fibre Cement (incl. James Hardie) | $12 – $20 |
For a typical home in the Niagara Region or Hamilton area, that usually translates to a full siding replacement somewhere between $10,000 and $30,000+, depending on size, material, and complexity. It’s a wide range — and for good reason.
Siding Cost in St. Catharines, Niagara Falls, Welland and Thorold
The ranges above are a realistic starting point for homes across the Niagara Region, including St. Catharines, Niagara Falls, Welland, Thorold, Grimsby and Port Colborne. What moves your number is the house itself. A few things we see often when we price Niagara homes:
- Newer subdivision homes with simple, repeating wall layouts usually sit toward the lower end of the range.
- Older homes in established neighbourhoods are more likely to need sheathing repair once the old siding comes off, which adds to the total.
- Homes with lots of windows, corners, dormers or gable ends take more time and material than a plain rectangle.
Because we look at every home in person, your quote is based on your house, not an average. You can see where we work on our service areas page, read about our roots on our Thorold siding contractor page, or book a free estimate.
What Actually Drives Siding Cost Ontario Wide
Home Size & Storeys
More square footage means more material and labour. A two-storey home also requires more time and equipment than a bungalow.
Material Choice
Vinyl is the most budget-friendly. Metal and fibre cement cost more upfront but bring different durability and appearance trade-offs.
What’s Underneath
Two homes that look identical from the street can price very differently once old siding comes off. Hidden rot or moisture damage adds cost — but it’s far cheaper to find and fix now than to cover it up.
Why Two Quotes for the Same House Can Look Different
If you’ve gotten quotes from more than one contractor, you may have noticed the numbers don’t match — sometimes by a lot. This usually isn’t one contractor overcharging and another lowballing. It comes down to what’s actually included.
A proper quote should account for removal and disposal of old siding, inspection and repair of the sheathing underneath, a proper moisture barrier, flashing around windows and doors, and cleanup. A quote that skips any of these steps might look cheaper on paper — but it usually means the work will need to be redone sooner, or worse, problems get sealed up behind new siding instead of fixed.
Why We Don’t Quote Prices Over the Phone
We get asked for a ballpark number often, and we understand the instinct to want one. But an honest quote requires actually seeing your home. Wall complexity, the number of windows and doors, corners, the condition of what’s underneath the existing siding, and access all affect the final price — sometimes significantly. A number given without seeing the house is a guess, not a quote.
What we can promise is a free, no-obligation estimate with a real walk-around of your home, an honest conversation about your options, and a written quote that spells out exactly what’s included.
