In Quebec in 2026, a custom interior staircase costs between $3,000 and $25,000, including manufacturing and installation. A straight staircase in hardwood is typically between $3,000 and $7,000. A winder staircase goes up to $5,000 – $12,000. A Central Stringer steel suspended model with glass railing typically exceeds $15,000. Labor accounts for 30-50% of the bill, the railing 15-30%, and taxes add up to 14.975%.
These are general price ranges for the Quebec market. The actual price of your project depends on the height to be crossed, the number of treads, the chosen wood species, the structure and the access to the site. Here is how each item breaks down, so you can read a quote in knowledge of the facts.
Prices by type of staircase
| Type of staircase | Installed range | Explaining the difference |
|---|---|---|
| Straight | 3 000 $ – 7 000 $ | The simplest to manufacture: a single flight, no corner step |
| Quarter turn (in L) | 4 500 $ – 9 000 $ | winder treads to cut one by one |
| Half turn (in U) | 5 500 $ – 12 000 $ | Two direction changes, intermediate landing |
| To Central Stringer | 6 000 $ – 15 000 $ | Machined steel beam, but only one load-bearing structure |
| Suspended or floating | 9 000 $ – 22 000 $ | Reinforced structural anchors, engineering calculation |
| Helicoidal | 8 000 $ – 20 000 $ | Curved geometry: each step is unique |
| Luxury custom | $15,000 – $35,000 and above | Noble woods, crafted ironwork, composite curves |
A winder staircase costs 60-100% more than an equivalent straight staircase, and the reason for this is entirely due to the treads corners: each has its own geometry, must be plotted, cut and assembled individually, and these are workshop hours that don’t exist on a straight staircase.
An interesting case: the central-stringer staircase, which, despite its contemporary look, is often more affordable than a classic U-shaped staircase, because it rests on a single steel beam rather than two stringers of machined wood.
How much does a staircase step cost?
| Component | Unit price | Note |
|---|---|---|
| Walk in chipboard | 7 $ – 20 $ | Substrate to be coated |
| Walk in pine | 25 $ – 45 $ | Soft wood, easily marked |
| Walks in maple or birch | 45 $ – 80 $ | The Quebec standard |
| Step in oak white or walnut | 70 $ – 150 $ | Noble essence |
| Butcher Block 2 to 3″ Step | 150 $ – 350 $ | Lamellas glued on edge |
| Wooden stringers (pair) | 200 $ – 1 000 $ | According to the essence and profiling |
| Central Stringer in steel | 1 500 $ – 7 500 $ | Machined custom, powder finished |
On a 14 treads staircase, the only choice of gas represents a difference of more than $1,000 before even installation. It is the most effective adjustment lever when a budget is tight. Comparative of hardwoods details the hardness and behaviour of each species.
The most underestimated job: the railing
The railing and the railing are priced per linear foot, and often account for 15-30% of the total budget, but on a staircase with a railing on both sides, these amounts double.
| Type of railing | Price per linear foot | 12 ft. straight wing |
|---|---|---|
| handrail wall mounted alone | 10 $ – 50 $ | 120 $ – 600 $ |
| Classic wood, balusters turned | 80 $ – 200 $ | 960 $ – 2 400 $ |
| Wood and steel balusters | 120 $ – 250 $ | 1 440 $ – 3 000 $ |
| Stainless Steel Wire Rope | 130 $ – 300 $ | 1 560 $ – 3 600 $ |
| Tempered glass, steel poles | 150 $ – 400 $ | 1 800 $ – 4 800 $ |
| wrought iron working | 200 $ – 400 $ | 2 400 $ – 4 800 $ |
| Frameless glass, invisible fixings | 300 $ – 600 $ | 3 600 $ – 7 200 $ |
The Five Factors That Make a Budget Slip
1. Labour — 30-50% of the total
The manufacture and installation of a staircase requires a qualified carpenter or cabinetmaker. In Quebec, the hourly rate for residential renovation is generally between $65 and $95 per hour, and this is the heaviest job, and the least compressible without sacrificing quality.
2. The shape of the staircase
Each corner step adds workshop time. A straight staircase is produced in series; a turn is made piece by piece.
3. Access to the site
A basement staircase, a narrow cage, a floor without clearance to manoeuvre the stringers: each constraint prolongs the installation by several hours, a variable that only a site visit can evaluate.
4. Finishing
Raw wood that is dyed and varnished on site does not cost the same as wood that is pre-varnished in the workshop. Expect between $500 and $2,500 depending on the surface area and the number of coats.
5. Compliance
If the existing staircase is not compliant, the structural renovation is added to the invoice. This is common in houses built before 1980, whose staircase frames are often too short and the risers too high. staircase standards in Quebec.
Three ways to reduce the bill
- Redo only what is worn out. If the load-bearing structure is healthy, replacing treads, railing and finishing costs 40 to 60% less than a new staircase. New or refurbished staircase explains how to cut.
- Choose the fuel according to the use, not the catalogue. The maple offers a hardness close to the oak for a lower cost, and on a low-traffic staircase, the birch is more than enough.
- Keep a simple geometry. If space allows, a straight staircase with a neat railing costs less than a turn with a standard railing — for a often more elegant result.
Frequently Asked Questions
What is the price of an interior staircase in Quebec?
Between $3,000 and $25,000 installed depending on the type, a straight staircase in hardwood is around $3,000 – $7,000, a model suspended on stringer steel exceeds $15,000.
How much does a stair step in hardwood cost?
$45 to $80 for the maple or birch, $70 to $150 for the oak white or walnut, and a chipboard walkway costs $7 – $20.
How much does an stair railing cost in Quebec?
From $80 to $200 for a wooden linear base, from $150 to $400 for tempered glass, and up to $600 for glass without a frame.
Is it cheaper to redo a staircase than to replace it?
Yes, usually 40 to 60% less, provided the supporting structure is healthy.
Are taxes included in these prices?
No. Add 14.975% (GST and QST) to the amounts shown.
Why are the ranges so wide?
Because a custom staircase is never the same twice. The height to be crossed, the number of treads, the fuel, the shape and the access to the site vary the price from single to triple.
