Why spiral staircase work in Coquitlam
Custom steel and aluminum spiral staircases for interior and exterior applications, engineered to BC Building Code for residential and commercial use.
Coquitlam spiral staircase work is mostly residential, secondary stairs, loft access, and rooftop deck access on Burke Mountain and Central Coquitlam custom homes. Occasional feature spirals appear on larger Burke Mountain architectural projects. Our Burnaby shop is 15 to 25 minutes up Lougheed Highway.
Coquitlam splits into two distinct metalwork markets. Burke Mountain and Westwood Plateau are active new-build custom home zones, mono stringer stairs, glass railings, and modern canopy structures going into the latest generation of architect-led homes. Meanwhile Maillardville, Ranch Park, and Eagle Ridge have 1950s, 80s housing stock cycling through railing and stair replacements. Our shop is 15 to 20 minutes up Lougheed Highway.

FAQs
Spiral Staircase questions from Coquitlam clients
Answers to the questions we hear most often from Coquitlam homeowners, architects, and GCs on spiral stairs projects.
Are spiral staircases common in Coquitlam custom homes?
As secondary stairs yes, loft access, rooftop access, and basement suite stairs are standard scopes in Burke Mountain, Westwood Plateau, and Central Coquitlam. As primary stairs, spirals are rare because code limits their use.
How much does a custom spiral staircase cost in Coquitlam?
Custom spiral staircase cost in Coquitlam depends on diameter (residential 48", 60" versus commercial egress 60"+), tread material, guard type, whether the application is interior or exterior, and finish spec. Exterior galvanized spirals for deck and rooftop access have different cost drivers than architectural feature spirals with premium materials and guards. <a href="/request-a-quote/">Request a quote</a> with your site dimensions and application and we'll follow up with project-specific pricing.
Can a spiral staircase be used as primary egress in BC?
Only in limited cases. BC Building Code allows spiral stairs as primary egress for a single occupant area and secondary stairs serving a limited number of occupants. Most residential spiral installations are secondary stairs (loft access, rooftop access, basement secondary stair) because the tread geometry doesn't meet standard egress dimensions. We confirm code compliance for your specific application during the design phase.
What opening diameter and headroom does a spiral staircase need?
A 48-inch diameter spiral needs a 50 to 52 inch rough opening; a 60-inch diameter spiral needs 62 to 64 inches. Headroom requirement is 6'-4" minimum for code-compliant installations, with 6'-8" preferred. Floor-to-floor height determines tread count and rise per tread. We verify these dimensions during the initial site visit.
Do you do exterior spirals for Burke Mountain rooftop decks?
Yes. Rooftop deck access via exterior galvanized spiral is common on Burke Mountain and Westwood Plateau custom homes with rooftop outdoor living spaces. Hot-dip galvanized steel and open-riser designs handle the climate.
Can you do feature spirals in Burke Mountain luxury custom homes?
Occasionally. Feature spirals for luxury custom homes on Burke Mountain typically use wood or stone treads, custom handrails, and glass or cable guards. Budgets reflect the custom scope.
What is the Coquitlam spiral project timeline?
6 to 10 weeks for standard residential projects. Feature spirals extend to 12 to 16 weeks with architectural coordination.
