Is vinyl siding or fiber cement siding better for homes in NB?

Both vinyl and fibre cement siding are good choices for NB homes, but fibre cement wins on long-term durability and performance in the Maritime climate, while vinyl wins on upfront cost and zero maintenance. The right choice depends on how long you plan to stay in your home, your budget, and whether you're willing to repaint every decade or two.

Let's put real numbers to the comparison for a typical NB home. A full siding replacement with vinyl on a 1,500 square foot bungalow runs approximately $11,000 to $18,000 installed. The same home with fibre cement (HardiePlank) runs $18,000 to $29,000 installed. That $7,000 to $11,000 gap upfront is the core trade-off. Over a 30 to 40 year period, however, fibre cement's durability advantage can make the math closer — vinyl may need a full replacement at 25 to 30 years, while quality fibre cement installations in NB regularly last 40 to 50 years with proper paint maintenance.

In NB's specific climate conditions, fibre cement holds a real performance edge. The province's 100+ freeze-thaw cycles annually are hard on vinyl — the material contracts significantly in cold temperatures and expands in summer heat, and after 15 to 20 years that cycling causes the material to become more brittle and the paint to crack and peel if surface-painted vinyl is used. Standard vinyl doesn't get painted, so fading is the main issue rather than peeling, but colour fade after 20 to 25 years can make older vinyl homes look tired. Fibre cement doesn't have this thermal movement problem to the same degree — it's dimensionally stable, which is why the paint holds up decade after decade.

For coastal NB properties — along the Fundy shore, Northumberland Strait, and Gulf of St. Lawrence — fibre cement is the stronger recommendation. Salt air, wind-driven rain, and persistent humidity accelerate the wear cycle on vinyl, and fibre cement's resistance to moisture absorption and salt exposure gives it a clear longevity advantage in these demanding environments.

Vinyl's genuine advantages shouldn't be dismissed. It requires no painting — ever. A properly installed vinyl siding job needs only occasional washing with a hose. For NB homeowners who aren't interested in ongoing maintenance commitments, this is a real quality-of-life benefit. Modern insulated vinyl siding with an EPS foam backer also adds R-value to your wall assembly, which matters in NB's cold winters — and the premium over standard vinyl is modest, typically $1 to $2 more per square foot. Insulated vinyl also dents less easily than hollow-back panels, which is worth noting in NB communities with significant hail or flying debris risk during storms.

Fibre cement's main maintenance requirement is repainting every 10 to 15 years, which costs $3,000 to $8,000 for a full exterior paint job on a typical NB home. Factor that into your long-term cost comparison. HardiePlank's factory-applied Colorplus finish is the premium option and holds up better than field-painted installations — it's worth the premium if your contractor offers it.

Installation quality matters enormously for both materials. Vinyl that's nailed too tight won't expand properly and will buckle in summer heat. Fibre cement that's installed without proper flashing at horizontal terminations will absorb moisture at the cut ends and fail prematurely. In both cases, hire a contractor with demonstrated experience with the specific material — ask to see examples of their work on NB homes.
