Choosing between vinyl and fibre cement siding is one of the most consequential exterior renovation decisions Ottawa homeowners face. The siding you select protects your home from Ottawa's brutal freeze-thaw cycles, -30°C winters, humid summers, and driving rain — while simultaneously defining your home's curb appeal and resale value. Both materials have passionate advocates, but the right choice depends on your budget, how long you plan to stay in the home, your aesthetic preferences, and how much maintenance you are willing to perform. This comprehensive 2026 guide compares every aspect of v...
Before comparing the two, it helps to understand exactly what each material is and how it is manufactured.
Vinyl siding is made from polyvinyl chloride (PVC) resin, extruded into panels that interlock and are nailed to the exterior sheathing. Modern vinyl siding has evolved significantly from the thin, easily damaged products of the 1970s and 1980s. Today's premium vinyl siding is thicker (0.044 to 0.055...
Fibre cement siding is made from a mixture of Portland cement, sand, water, and cellulose fibres (wood pulp). The most well-known brand is James Hardie (HardiePlank), which dominates the Canadian market. The material is extremely dense and heavy — approximately 2.5 pounds per square foot compared to...
Cost is typically the deciding factor for most Ottawa homeowners. Here is what you can expect to pay in 2026.
Vinyl siding installed in Ottawa costs between $6 and $10 per square foot for standard vinyl, and $9 to $14 per square foot for premium insulated vinyl. For a typical 2,000 square foot Ottawa home with 1,200 to 1,500 square feet of exterior wall area, total installed cost ranges from $8,000 to $15,0...
Vinyl siding requires virtually no maintenance beyond occasional pressure washing. It never needs painting. However, damaged panels must be replaced (and colour matching older vinyl can be difficult). Over 30 years, vinyl's total cost of ownership is approximately $10,000 to $20,000. Fibre cement re...
Ottawa's extreme climate is the ultimate test for any siding material.
Vinyl siding becomes brittle in extreme cold. At temperatures below -20°C (common in Ottawa from December through February), a direct impact — such as a hockey puck, falling ice, or kicked-up stone from a snowblower — can crack vinyl panels. This is the single biggest complaint about vinyl siding in...
Vinyl siding expands and contracts with temperature changes. In Ottawa's summers (which can reach 35°C+ with humidity), vinyl panels can warp, buckle, or wave if improperly installed without adequate expansion gaps. Quality installation with proper nailing technique virtually eliminates this issue. ...
The visual difference between vinyl and fibre cement is noticeable, particularly up close.
Fibre cement siding looks and feels like real painted wood. The texture depth, shadow lines, and colour richness are superior to vinyl. Fibre cement accepts any exterior paint colour, so you have unlimited colour options (including dark colours that would cause warping issues on vinyl). Vinyl siding...
In Ottawa's real estate market, fibre cement siding typically adds 3% to 7% more to home value compared to vinyl. For a $600,000 Ottawa home, that is $18,000 to $42,000 in additional perceived value. Homes in premium Ottawa neighbourhoods (Rockcliffe Park, The Glebe, Westboro, Manotick) particularly...
The best choice depends on your specific situation and priorities.
Budget is your primary concern and you want the lowest upfront cost. You plan to sell within 5 to 10 years and want a clean, attractive exterior without a premium investment. You want zero maintenance beyond occasional washing. Your home is in a neighbourhood where vinyl siding is the standard exter...
You plan to stay in your home long-term (15+ years) and want the most durable exterior. You want the most authentic wood-like appearance without the maintenance of real wood. Your home is in a premium Ottawa neighbourhood where curb appeal matters significantly. You want maximum fire resistance (imp...
Quality vinyl siding lasts 25 to 40 years in Ottawa. Insulated vinyl tends to last longer because the foam backing reduces impact damage from cold-weather brittleness. The main threats to vinyl longevity in Ottawa are impact damage in extreme cold and UV fading over time.
Fibre cement siding lasts 40 to 60+ years with proper maintenance. James Hardie offers a 30-year non-prorated warranty on their products. The key to longevity is keeping paint and caulking maintained to prevent moisture infiltration.
No. Fibre cement is too heavy to install over existing siding. The old siding must be removed, the sheathing and house wrap inspected and repaired, and the fibre cement installed fresh. This adds $1 to $2 per square foot in removal costs.
Fibre cement is more durable in Ottawa winters because it does not become brittle in extreme cold. However, insulated vinyl is a strong performer that addresses many of vinyl's cold-weather weaknesses while remaining more affordable.
Yes. Fibre cement siding typically adds 3% to 7% more to home value compared to vinyl in Ottawa's market. The premium is largest in upscale neighbourhoods like Rockcliffe Park, Westboro, and The Glebe.
