Custom Stairs in the Niagara Region

Custom stairs, Niagara Region: parametric CAD design, CNC-cut joinery, and hand-finished treads — built to your specification. You decide the profile, species, railing material, and surface finish; we design, fabricate, and install across St. Catharines, Niagara Falls, Welland, Thorold, and the rest of the region.

What “custom” means in our shop

Off-the-shelf staircases are dimensioned for an idealized opening. Real Niagara homes — century homes in old St. Catharines, post-war bungalows in Welland, new builds in Niagara-on-the-Lake — almost never match the catalogue. Every staircase we deliver is modelled parametrically: each tread, riser, stringer and newel is computed from the actual rough-opening dimensions we measure on site, then cut on our CNC router with sub-millimetre repeatability.

That precision lets us specify joinery that lasts: housed stringers with wedged treads, mortise-and-tenon newels, and dovetailed risers that won't squeak through the first ten Ontario winters. Glue-ups happen in our climate-controlled shop on Lakeshore Road, not in your living room.

What you control at the outset is the form. A straight run is the most economical and the most common retrofit. A quarter-turn or half-turn landing redirects the climb and opens sight-lines on a split-level plan. A U-shaped return fits a tighter footprint; floating and cantilevered designs — with structural steel stringers and open treads — let light pass through the stair and make it the architectural centrepiece of the room. We model every configuration from your rough-opening dimensions, so you see the geometry in CAD before a single board is cut.

Materials we work in

You specify the species and grade; we source board-selected hardwood stock from regional suppliers and build to a moisture-content spec that accounts for Niagara's climate range. Red oak remains the most-specified choice — stable, hard (Janka 1290), and forgiving of humidity swings between a 70%+ RH summer near the lake and a 20% RH January. White oak reads more contemporary and resists tannin pull-out under modern matte finishes. Hard maple takes a glass-smooth surface for lighter palettes; black walnut and hickory dominate feature stairs where a single open run sets the tone of the room. For mixed-material designs you might specify steel stringers with glass guards, or aluminum balustrade with a wood cap rail — we work in all of them.

Ontario Building Code compliance — without compromise

Every set of drawings we produce honours OBC O. Reg. 332/12 Section 9.8: maximum rise 200 mm, minimum run 235 mm, minimum tread depth 254 mm with a maximum 25 mm nosing, headroom no less than 1950 mm, and a uniform variation tolerance of 5 mm across all risers. Handrails sit between 865 and 965 mm above the nosing line, and guards meet the 100 mm sphere rule for any opening below the rail. When a municipal inspector in St. Catharines or Niagara Falls asks for stamped drawings, we can produce them through our partner engineer. You choose your guard configuration — glass panel, aluminum picket, wood baluster, or a combination — and we confirm the compliant geometry before fabrication begins.

Recent regional projects

A floating white-oak stair with a 12 mm tempered-glass guard in a Ridley Heights new-build (St. Catharines, 2025) — the owners specified quarter-sawn oak for its straight grain and minimal figure. A curved walnut feature stair in a Niagara-on-the-Lake heritage renovation (2024), where the profile had to match existing Victorian millwork. A steel-and-oak split landing in a Welland multi-generational home (2024), engineered to redirect the climb without touching the existing floor structure. And a dozen straight oak runs across Thorold, Fonthill, and Grimsby for clients who needed their core staircase replaced without rebuilding the surrounding millwork. Each project began with an in-home measurement visit and ended with a staircase dimensioned to that specific rough opening.

Process and warranty

Every project follows the same five steps: free in-home consultation, parametric CAD design, CNC fabrication, hand-finishing, and installation by our own crew — no subcontracted installers. We serve St. Catharines, Niagara Falls, Welland, Thorold, Grimsby, and the surrounding communities — all within a short drive from our Lakeshore Road shop. Workmanship is guaranteed for ten years against squeaks, separation, and finish failure under normal residential use.

Frequently asked questions

How much do custom stairs cost in the Niagara Region?

A residential custom staircase in St. Catharines, Niagara Falls or Welland typically ranges from $6,500 for a straight stained-oak run to $25,000+ for floating, curved or mixed-material designs. Final price depends on rise/run, species, railing type and substructure work.

How long does a custom staircase take from measurement to install?

Allow 3 to 6 weeks. We dedicate the first week to in-home measurement and CAD modelling, 1–2 weeks to CNC fabrication and hand-finishing in our St. Catharines shop, and 1–3 days for on-site installation.

Which wood species hold up best for stairs in Ontario homes?

Red and white oak remain the regional favourites for their hardness (Janka 1290–1360) and stable behaviour through Niagara's humidity swings. Hard maple is a strong second; walnut, hickory and ash are common for feature stairs.

Do custom stairs comply with the Ontario Building Code?

Yes. Every stair we build follows OBC O. Reg. 332/12 Section 9.8: maximum rise 200 mm, minimum run 235 mm, headroom ≥ 1950 mm, handrail height 865–965 mm and a 100 mm sphere rule on guards. Drawings are stamped-ready when permits require it.

Can you replace an existing staircase without rebuilding the whole opening?

In most cases, yes. We retrofit new treads, risers, stringers and railings into the existing rough opening. We provide load calculations and structural notes for inspectors when load paths or guards change.
