How Long Does a Custom Staircase Take in Ontario? Complete Timeline Guide

One of the most common questions we receive at C.O.R.S Staircases in Barrie is: “How long is this going to take?” Whether you’re planning a floating staircase installation or a full traditional staircase renovation, the timeline from first consultation to move-in-ready staircase is longer than most homeowners expect — and for good reason. Here’s a realistic, honest breakdown of the custom staircase timeline in Ontario in 2026.

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.

Quick Summary: Custom Staircase Timeline in Ontario

• Tread-only upgrade (no permit required): 4–8 weeks total from consultation to installation
• Traditional staircase renovation (with permit): 10–16 weeks total
• Floating mono-stringer staircase (with permit): 12–20 weeks total

These timelines assume a normal project flow without significant design changes or permit delays. Major projects in Toronto and the GTA may run longer due to municipal permit processing times.

Phase 1: Initial Consultation and Design — 1–2 Weeks

After you contact us, the first step is scheduling an on-site consultation at your home. During this visit — typically 1–2 hours — we:

• Assess your existing staircase structure, dimensions, and condition
• Discuss design preferences: stringer finish, tread species, railing type
• Take precise measurements of the staircase opening and floor-to-floor height
• Discuss budget range and any structural considerations

Following the consultation, we prepare a detailed, fixed-price quote. Most clients receive their quote within 5–7 business days. Once you accept the quote and sign the contract, the project moves to engineering.

Phase 2: Engineering Drawings — 2–4 Weeks

For floating staircase projects, our P.Eng team prepares stamped engineering drawings. This phase takes 2–4 weeks depending on project complexity. Tread-only replacement projects (no structural changes) skip this phase.

Phase 3: Building Permit — 3–8 Weeks (if required)

Most structural staircase projects in Ontario require a building permit. We submit the permit application with engineering drawings on your behalf. Processing times vary by municipality:

• Simcoe County municipalities (Barrie, Bradford, Innisfil): Typically 3–6 weeks
• York Region (Newmarket, Aurora, Vaughan, Markham): Typically 4–8 weeks
• Toronto: Variable — can range from 6–12 weeks depending on current workload
• Tread replacement (no structural change): Permit may not be required — confirm with your local building department

Permit processing is the most variable phase of the timeline. We recommend starting the process as early as possible.

Phase 4: Fabrication — 3–6 Weeks

Once the permit is approved, fabrication begins at our Barrie facility. For a floating staircase, this includes:

• Steel stringer cutting, welding, grinding, and powder coating
• Hardwood tread milling, dimensioning, profiling, and pre-finishing
• Glass panel ordering and processing (lead time of 2–4 weeks from glass fabricators)
• All hardware, brackets, and connection components

Fabrication for a standard floating staircase takes 3–5 weeks. Complex multi-level or custom geometry projects may take longer.

Phase 5: Installation — 1–3 Days

Installation at your home is typically 1–3 days for a residential floating staircase — the shortest phase despite being the most visible. Our installation team works efficiently and leaves the site clean and ready for daily use. During installation, the existing staircase is temporarily inaccessible — plan accordingly if you have multiple floors.

Phase 6: Post-Installation Inspection — 1–2 Weeks

After installation, we coordinate with your local building department for the post-installation inspection. This typically happens within 1–2 weeks of installation completion. We handle the inspection coordination; you simply make the home available.

How to Avoid Timeline Delays

• Contact us early: The consultation-to-permit phase is the longest. Starting early gives you more control over your renovation timeline
• Finalize design decisions quickly: Design changes after permit submission restart the permit process
• Confirm permit requirements early: For tread-only replacements, confirm with your municipality whether a permit is required — this can save 6–8 weeks
• Schedule around your life: Discuss installation timing with us — we can often schedule to avoid family vacations, holidays, or major events at your home
