Most Simcoe County homeowners who get a quote for a custom staircase don’t realise they’re often comparing two fundamentally different products: one built to the specific dimensions of their home in a dedicated fabrication workshop, and one assembled from manufacturer-supplied components on-site. Both companies call themselves custom staircase builders. The outcomes are not equivalent. Here is what in-house fabrication actually means — and why it matters for Simcoe County homeowners specifically.
Ontario homeowners can find registered staircase contractors through the Home Construction Regulatory Authority (HCRA) — C.O.R.S Designs is a fully compliant Ontario staircase company.
What “In-House Fabrication” Actually Means
In-house fabrication means the company that designs and installs your staircase also builds it — in their own workshop, using their own equipment, from raw material. For a C.O.R.S staircase, that means:
- A steel stringer is cut from structural steel stock to the exact length required by your floor-to-floor height and staircase configuration
- Tread brackets are welded to the stringer at the exact rise spacing from the design drawings — not at a standard spacing from a manufacturer’s template
- Every weld is ground flush and the entire assembly powder-coated in-house
- Hardwood tread blanks are milled to the exact depth, width, and thickness required by your opening — not cut from a pre-cut manufacturer standard tread
- Every tread is stained to the exact colour approved in your design consultation, not to a manufacturer’s catalogue option
- The full staircase — stringer, treads, railing posts, glass panels, handrail — is assembled in the workshop for a dry-fit confirmation before anything ships
What “Component Assembly” Means
The alternative model — which is common among general contractors and some staircase companies — involves sourcing pre-fabricated components from a staircase manufacturer:
- Steel stringers arrive as catalogue items in standard lengths, cut to approximate size on-site
- Tread brackets are pre-welded at standard spacing — adjustments are shimmed or field-modified
- Treads are manufacturer pre-cuts, available in a range of standard lengths and widths
- Finish options are the manufacturer’s catalogue — limited stain colours, standard thickness
- No workshop dry-fit is possible because the company doesn’t have a workshop — assembly is on-site only
This is not necessarily inferior for simple projects, but it has real limitations: you’re working within a manufacturer’s tolerances and options, not custom specifications. The visual result for a complex configuration — an L-shaped mono-stringer, a specific staircase width, a non-standard opening — is where the difference shows most clearly.
Why This Matters Specifically for Simcoe County
Most Ontario staircase manufacturers and component suppliers are based in the GTA. A company in Barrie, Innisfil, or Collingwood that sources components from a GTA manufacturer is adding transit time, freight cost, and a communication layer to every project. When a component arrives damaged or doesn’t fit correctly, the solution involves shipping it back to the manufacturer or ordering a replacement — both of which add days or weeks to your project.
C.O.R.S fabricates locally. A correction that would take a GTA-sourcing company 2 weeks to resolve through a manufacturer takes us 2 days to fabricate and redeliver. For Simcoe County homeowners — where “getting someone back out to the site” means a realistic travel round trip — this matters.
The Dry-Fit Standard (and Why Only In-House Fabricators Can Do It)
A workshop dry-fit — assembling the complete staircase in the workshop before delivery to confirm everything fits — is only possible if you have a workshop with the floor space to set up a full staircase. Most staircase component assemblers don’t have this capacity. The dry-fit is exclusively an in-house fabricator’s quality step.
What the dry-fit catches:
- Tread bracket alignment across the full flight — a 1 mm bracket misalignment at step 3 creates a visible tilt visible on every tread
- Glass panel width vs. channel opening — tempered glass cannot be trimmed on-site. A panel that is 5 mm too wide goes back to the glass supplier
- Handrail splice points — at a return from the staircase to a landing, the handrail must curve or splice cleanly. Confirmed in the dry-fit
- The visual line of the assembled staircase seen from the main floor — whether the treads project evenly, whether the stringer spine is centred, whether the glass panels are plumb

Frequently Asked Questions
How do I know if a Simcoe County staircase company fabricates in-house?
Ask directly: “Do you fabricate steel stringers and mill hardwood treads in your own workshop, or do you source components from a staircase manufacturer?” A legitimate in-house fabricator will answer this immediately and specifically — they’ll describe their equipment, their shop, and their process. A company that sources components will typically give a vague answer about “custom design” without describing fabrication specifics. Follow up: “Do you do a workshop dry-fit before delivery?”
Does in-house fabrication cost more?
For comparable quality, in-house fabricated staircases and high-quality component-sourced staircases typically land in similar price ranges. In-house fabrication’s premium is in outcomes: tighter tolerances, custom specifications that can’t be achieved with manufacturer components, and the dry-fit quality step. A very low-cost quote for a complex custom staircase in Simcoe County should raise the question of whether the outcome will match the design intent.
