How much does new siding cost for a home in New Brunswick in 2026?

New siding on a typical New Brunswick home costs $12,000 to $30,000 fully installed in 2026, depending on the material you choose, the size of your home, and the amount of prep work required. That range reflects the full spectrum from economical vinyl siding on a modest bungalow to fibre cement or engineered wood on a larger two-storey with complex trim detailing.

Breaking it down by material: vinyl siding is the most affordable option at $6 to $10 per square foot installed, making it the most common choice in NB. A standard 1,500 square foot bungalow with roughly 1,800 square feet of exterior wall surface (accounting for gables) typically runs $11,000 to $18,000 for a full vinyl siding replacement. Fibre cement siding (HardiePlank) runs $10 to $16 per square foot installed — the same bungalow would cost $18,000 to $29,000. Engineered wood siding (LP SmartSide) falls in between at $8 to $14 per square foot installed. Cedar shingles and shake are at the premium end at $12 to $20 per square foot, typically reserved for accent areas or heritage-style homes.

The price per square foot is only part of the story. Prep work adds significant cost on older NB homes, and this is where estimates can vary dramatically between contractors. If your existing siding is in poor condition, you may face removal and disposal costs ($1.50 to $3.00 per sq ft), repairs to the sheathing or housewrap underneath, and additional work around windows and doors where flashing has failed over the years. NB homes built before 1990 sometimes reveal moisture damage behind the old siding once it's removed — rotted sheathing, deteriorated window sills, and failed flashings are common findings. This is why a 15 to 20% contingency budget is smart for a siding project on an older home.

Insulated vinyl siding is worth considering for NB's climate. It adds a layer of rigid foam insulation behind the vinyl panels, improving your wall's thermal resistance noticeably without a full exterior insulation retrofit. The premium over standard vinyl is modest — typically $1 to $2 more per square foot installed — and the energy savings in NB's cold winters can make it worthwhile over the life of the siding.

Labour accounts for 40 to 50% of a siding project's cost in NB, which means material fluctuations have a proportional impact. Material costs in 2026 have been elevated compared to pre-pandemic pricing but have stabilized relative to the peaks of 2022 and 2023. Getting 3+ quotes from local contractors is essential — NB siding prices can vary 20 to 40% between contractors for identical scope. Always confirm that each quote is covering the same prep work, flashing replacement, and disposal so you're comparing apples to apples.

Timing matters for both scheduling and quality. Siding installation in NB should happen between May and October — vinyl becomes brittle in cold temperatures and is prone to cracking during installation if the ambient temperature drops below 5 degrees Celsius. Adhesives and sealants also need temperatures above 10 degrees to cure properly. Contractors who install siding in NB winters are cutting corners on quality.
