What is the cost to install stair treads and risers in hardwood for a two-storey NB home with 13 steps?

Hardwood stair treads and risers for 13 steps in New Brunswick typically cost $2,500-$5,500 fully installed, depending on wood species, existing stair condition, and complexity of the installation.

Material costs for 13 steps run $800-$2,200. Red oak treads (the most popular choice in NB) cost $60-$100 per tread, while risers run $25-$45 each. Premium species like white oak or maple increase costs to $80-$140 per tread. You'll also need stair nosing, scotia molding for underneath, and matching wood stain and polyurethane finish.

Installation labour adds $1,700-$3,300 to the project. Stair installation is precision carpentry requiring exact measurements, proper overhang calculations, and seamless integration with existing railings and balusters. Most NB contractors charge $130-$250 per step for installation, with higher rates for curved stairs, open risers, or complex trim work.

Additional costs often surprise homeowners. If your existing stairs have carpet, removal and disposal add $200-$400. Subfloor preparation or structural repairs can add $300-$800. Many NB homes built before 1980 have stairs that aren't perfectly square or level, requiring shimming and adjustment work. If you're matching existing hardwood floors, custom staining to achieve a perfect colour match adds $200-$500.

New Brunswick's humidity cycles make proper wood acclimation critical for stair installations. Hardwood must sit in your home for 5-10 days before installation to reach moisture equilibrium. Installing wood straight from delivery in NB's variable humidity leads to gaps, squeaks, and movement issues within the first year. Winter installations require extra attention since heated indoor air drops humidity to 20-30%, causing wood to shrink more than expected.

Timing matters significantly in NB. Schedule stair installations for late summer through fall when humidity is most stable. Spring installations during snowmelt season risk moisture issues, while winter installations during peak heating season can cause excessive wood movement as humidity drops.

Most homeowners should hire a professional for stair work. Unlike flat flooring, stairs involve structural safety, precise angles, and building code compliance for riser height and tread depth. Mistakes create safety hazards and are expensive to correct. A poorly installed tread can separate from the stringer, creating a dangerous fall risk.

Get quotes from 3+ contractors since NB stair pricing varies significantly. Some specialists charge premium rates for complex work, while general carpenters may underbid and struggle with the precision required. Verify that your installer carries liability insurance and ideally WorkSafeNB coverage for this type of structural work.
