How do I install flooring on stairs in a New Brunswick home?

Stair flooring installation is one of the most technically demanding flooring projects and is almost always a job for a professional installer, regardless of the material you choose. Each step is a small, precise project involving exact measurements, custom cuts for treads and risers, proper nosing installation, and secure attachment — the consequences of poor stairway flooring include tripping hazards and premature wear.

Hardwood stair treads are the most popular choice in NB homes and deliver a beautiful, durable result that can last decades with proper care. Pre-made hardwood stair treads (red oak, white oak, or maple) run $30-$80 per tread in NB, with risers at $15-$30 each. Installation labour runs $40-$80 per step, so a standard 13-step staircase costs roughly $1,500-$3,000 fully installed with matching nosing. Each tread must be custom-fitted to the stringer width, glued and nailed with precision, and finished with a bullnose or flush nosing at the front edge.

In NB's Maritime climate, hardwood stair treads experience the same humidity-driven expansion and contraction as hardwood floors. Proper acclimation — 5-10 days in your home's living conditions — is just as critical for stair treads as for floor planks. During NB's winter heating season when indoor humidity drops to 20-30%, minor gaps may appear between treads and risers. A whole-home humidifier maintaining 35-45% relative humidity during heating season helps minimize this movement.

LVP on stairs is growing in popularity across NB for its durability, waterproof properties, and lower cost. LVP stair installations require each plank to be glued directly to the stair substrate — the click-lock floating method used on flat floors does not work on stairs. Specialty stair nosing pieces designed for LVP are essential for a safe, finished edge. Expect to pay $25-$50 per step for materials plus $30-$60 per step for professional installation.

Carpet on stairs remains a practical choice for NB homes, especially for noise reduction and warmth during long winters. Professional carpet installers use a waterfall or cap-and-band method, stretching and stapling carpet tightly around each tread and riser. Budget $15-$30 per step for materials and $20-$40 per step for installation. Carpet runners over finished hardwood stairs offer the best of both worlds — the beauty of hardwood with added traction and noise dampening.

Key considerations for NB stair installations. Many older NB homes — particularly pre-1970s houses in Saint John, Fredericton, and Moncton — have stairs with uneven riser heights or non-standard tread depths. A professional installer will measure every step individually because even small variations affect safety and appearance. Building code requires consistent riser heights within 3/8 inch across a staircase, so significant variations may need correction before new treads go on.

Safety is the overriding priority with stair flooring. Loose treads, inadequate nosing, and slippery finishes on stairs are genuine fall hazards, particularly in homes with young children or older adults. Any stair flooring material must be securely fastened (never floating), and the nosing must provide a visible, slip-resistant edge.

This is a project where hiring an experienced professional is strongly recommended. A poorly installed stair floor is not just unattractive — it is dangerous. New Brunswick Flooring can match you with local installers experienced in stairway flooring for a free estimate.
