Siding for an Ontario House: Every Cladding Compared on Cost, Life, Maintenance and How It Behaves at Minus 30
Siding is the raincoat and the face of the house at the same time, and it has to do both through forty freeze-thaw cycles a winter. Here is every cladding we put on houses, what it costs installed in 2026, and the one detail under all of them that matters more than the choice.
Short version: The cladding keeps most of the rain off; the drainage plane behind it (house wrap or taped sheathing, flashings, and a rainscreen gap) keeps the wall dry, and the Code expects it. On top of that: vinyl is the cheapest ($6 to $12 per square foot installed) and fades and cracks in cold; fibre cement ($12 to $20) and engineered wood ($10 to $18) are the mid-range workhorses with 30 to 50 year lives; real wood ($14 to $25) is beautiful and needs finishing every few years; steel ($14 to $24) is the low-maintenance choice that shrugs off hail and sun; brick veneer ($25 to $45) lasts a century; stone veneer ($30 to $60) is the look of the moment; stucco and EIFS need an installer who understands water. Mix two: brick or stone at the base, something lighter above. On an ICF wall every one of them attaches to the embedded webs, with a drainage plane over the foam.
The layer that matters more than the siding
No cladding is waterproof. Wind drives rain behind every lap and around every window. What keeps the wall dry is a continuous water-resistive barrier behind the siding (house wrap or taped sheathing), flashings that lap in the right order at every opening and transition, and a drainage gap (rainscreen) so water that gets behind the siding runs out the bottom and air dries the back. Ontario’s Building Code requires a second plane of protection behind cladding and, in wetter zones, a capillary break; in practice a rainscreen strapping or a drainage wrap is the standard for a house you want to last. Get this layer right and the cladding choice is about looks, cost and maintenance. Get it wrong and the best siding rots the sheathing behind it.
Every cladding, compared
| Cladding | 2026 installed, per sq ft | Life | Maintenance | Cold-climate notes |
|---|---|---|---|---|
| Vinyl | $6 to $12 | 20 to 30 yr | None, but cannot be refinished | Gets brittle below minus 20; cracks when hit; expands a lot, so it must hang loose |
| Fibre cement (Hardie type) | $12 to $20 | 40 to 50 yr | Repaint every 10 to 15 yr unless pre-finished | Heavy, cuts with dust control; handles freeze-thaw well; needs correct clearances and flashing |
| Engineered wood (LP type) | $10 to $18 | 30 to 50 yr | Repaint 10 to 15 yr | Lighter and easier than fibre cement; keep the cut ends sealed |
| Real wood (cedar, pine) | $14 to $25 | 30 to 60 yr with care | Stain or paint every 3 to 7 yr | Looks best, costs the most in weekends; back-prime and use a rainscreen |
| Steel or aluminum | $14 to $24 | 40 to 60 yr | Almost none | Hail, sun and fire resistant; dents; steel over aluminum for strength |
| Brick veneer | $25 to $45 | 75 to 100 yr | Repoint in 30 to 50 yr | Needs a foundation ledge, weep holes and an air space; the Ontario default for a reason |
| Manufactured stone veneer | $30 to $60 | 40 to 60 yr | Little; watch the sealant | Over a drainage mat and lath; the failures are water behind it, not the stone |
| Stucco / acrylic | $15 to $25 | 30 to 50 yr | Patch and recoat | Must be a drained system; conventional stucco on a rainscreen |
| EIFS (foam-backed) | $18 to $30 | 30 plus if drained | Little | Only the drainable kind, by a certified installer; the old barrier type is the one in the lawsuits |
Costs are for a straightforward two-storey with normal detailing; corners, gables, trims and a complex elevation add quickly. The real cost of upgrades shows where exterior money shows at resale.
Choosing for the house
- Match the style: a farmhouse in board-and-batten engineered wood, a bungalow in brick, a chalet in wood and stone. Vinyl on a Victorian is a sin against the house.
- Mix materials on purpose: masonry on the lower third where splash and snow hit, lighter cladding above. It looks right and it puts the expensive material where it works.
- Pre-finished beats site-painted in this climate; factory coatings last twice as long.
- Colour: dark siding runs hot and fades faster; vinyl in dark colours needs the heat-reflective kind or it warps.
- Exposure: a lake-facing wall in Georgian Bay gets more wind-driven rain in a year than a city wall gets in five. Spend there.
- Future you: if you will not stain a wall every four years, do not buy a wall that needs it.
On an ICF wall
Every cladding on this list goes on an ICF house. The siding screws to the plastic webs embedded in the foam at 8 or 12 inches on centre, over a house wrap or drainage layer on the foam; brick and stone veneer sit on the foundation ledge with a brick tie system designed for ICF; stucco and acrylic finishes go directly over a base coat on the foam as a drained system. The detail that changes is the window: the buck and the flashing sit in a thick wall, and the installer has to have done one before. What ICF is covers the wall; how to buy windows covers the openings in it.
What goes wrong
- No flashing over windows and doors, or flashing lapped backwards so it drains into the wall.
- Siding tight to the roof or the grade; most products want a 1 to 2 inch gap at roofs and 6 inches at grade.
- Vinyl nailed tight, so it buckles in July and cracks in January.
- Stone veneer with no weep screed or drainage, holding water against the sheathing.
- Caulking used as flashing. Caulk is a maintenance item; flashing is a building component.
- Fibre cement cut without dust control, or installed with the wrong clearances, voiding the warranty.

Questions people ask
What is the best siding for an Ontario house?
For most houses, fibre cement or engineered wood for the body and brick or stone veneer at the base: 30 to 50 year lives, good freeze-thaw behaviour, moderate cost. Steel is the low-maintenance choice; vinyl is the budget choice and gets brittle in deep cold. Whatever you pick, the drainage plane and flashing behind it matter more.
How much does siding cost in Ontario in 2026?
Installed, roughly $6 to $12 per square foot for vinyl, $10 to $20 for engineered wood and fibre cement, $14 to $25 for real wood or steel, $25 to $45 for brick veneer and $30 to $60 for stone veneer, before trims and complex detailing.
Does the Building Code say anything about siding?
Yes: it requires a second plane of protection (a water-resistive barrier) behind cladding, flashing at openings and transitions, clearances at grade, and in wetter regions a capillary break; masonry veneer has its own rules for ties, weep holes and the air space.
Can you put brick or stone on an ICF house?
Yes. Brick and stone veneer sit on the foundation ledge with a tie system made for ICF and an air space; siding screws to the embedded webs; stucco goes on as a drained system over the foam. All of it over a drainage plane.

I can imagine how changing the siding of a building can drastically change the appearance. I never considered these other benefits like lower utility and maintenance costs. I think stone siding is the best looking and love all of the different patterns and colors that are available.
My husband and I have decided that we want to get a custom home built. I like how you point out that there are several different types of siding that have different functions. It’s interesting to learn that siding vinyl can expand and contract in hot and cold weather and will slide freely from side to side. It is also inexpensive and doesn’t need painting. We are very low maintenance people, so having something like this sounds like a great option for us.
I prefer brick, but for our next house we will choose vinyl because it has more variety and designs to choose from.
I didn’t know that there were so many choices for home panel siding. This is going to help my fiance and I a lot as we look into getting new siding for our new home. We like composite siding since it will look like real wood.
I did not know there were so many different options for siding! This information will be very helpful while we look for siding for our home.
If I buy a 19 year old siding home how do o know if it is still weather proof or rotted underneath. Ad well a 2400ft home would cost how much to replace and when would I do this and at what age.
Please call the reputable home inspector.
There is no way of appraising the situation without being there.
My wife has been thinking about getting some more exterior work done for the house and I want to help her find out what our choices are. I was interested when you stated that log sidings are a great way to get that classic log home without rebuilding it because my wife has opted for a less city-looking house and a more country-style design and so this could help nail that aesthetic. Once we find a siding installation service that can help us, we’ll be sure to inquire about these kinds of products. Thank you for the article!
Brick can last a century. Because itβs made from fired clay, brick doesnβt burn and is not susceptible to dry rot. Brick and wood are really good combination.
Thank you for explaining how it can be a good idea to replace your siding if you want to lower your utility bills. I’ve been wondering if there’s more ways to make our home energy efficient. I’ll have to look more into these options to see what might work out best for the siding of our home.
