Spiral Stairs, Squamish, BC
Custom spiral staircases for Squamish homes, Garibaldi Highlands, Eaglewind, Brackendale, and Downtown Squamish. Residential and rooftop access spirals.
Spiral Stairs, Squamish
Custom steel and aluminum spiral staircases for interior and exterior applications, engineered to BC Building Code for residential and commercial use.
Squamish spiral staircase work is primarily residential secondary stairs on Garibaldi Highlands, Eaglewind, and Brackendale homes. Rooftop access spirals on mountain-view lots are a growing scope. Our Burnaby shop is 1 hour from Squamish.
Squamish sits between the coast and the mountains with aggressive weather on both sides, heavy rain in the valley, higher snow loads at elevation, wind off the Howe Sound. Residential metalwork here leans into the 'timber-and-steel' alpine aesthetic: structural steel brackets, black powder-coated railings, cable systems on view lots in Garibaldi Highlands. Eaglewind and Newport Beach are active new-build areas; Downtown Squamish has ongoing density and commercial work.
Configurations we fabricate
Squamish context
Squamish's climate, building stock, and permit process shape every spiral stairs project we deliver here.
Climate
Design snow load for Squamish is roughly 3 kPa ground. Coastal exposure is moderate. Sea-to-Sky seismic zone, higher activity than Vancouver proper. These are the numbers the engineer pulls when sizing steel for a spiral stairs here.
Permits
District of Squamish permits 6 to 10 weeks standard. Higher snow load and wind exposure mean engineered drawings are almost always required on canopies and stair structures.
Local neighbourhoods
We work throughout Squamish, including Downtown Squamish, Garibaldi Highlands, Brackendale, Valleycliffe, Hospital Hill, Eaglewind, Newport Beach, Dentville. Most sites are a 1 hour drive from our Burnaby shop.

All figures include fabrication, finish, and installation. For a Squamish-specific project quote, request a quote.
Process
1. Site visit and opening check. Confirm the opening diameter, headroom clearance, and floor-to-floor height for code compliance.
2. Engineering. Sealed drawing sizing the central column, tread brackets, and guard system to code.
3. Shop drawings. Tread layout, column section, guard detail, and finish schedule.
4. Fabrication. Central column, tread brackets, and guard fabricated at our Burnaby shop.
5. Finishing. Powder coat for interior; hot-dip galv + powder coat for exterior applications.
6. Installation. 1 to 2 days for a residential spiral; longer for complex commercial applications.

FAQs
Answers to the questions we hear most often from Squamish homeowners, architects, and GCs on spiral stairs projects.
Squamish spiral staircase cost depends on diameter, tread material, guard type, interior versus exterior application, and whether the project is a residential secondary stair or a feature spiral in a Garibaldi Highlands custom home. Mobilization from our Burnaby shop (approximately 1 hour) is included in the project scope. <a href="/request-a-quote/">Request a quote</a> with your site dimensions and we'll follow up with project-specific pricing.
Custom spiral staircase cost in Squamish 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.
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.
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.
Yes, occasionally. Mountain-view properties with rooftop decks or observation platforms sometimes specify exterior spirals for access. We use hot-dip galvanized steel and open-riser designs to handle the climate.
For interior spirals, no direct effect. For exterior rooftop access spirals, snow accumulation on open-riser treads is generally not a major issue because the open-tread design lets snow fall through. Landing platforms require snow-load engineering similar to other exterior structures.
8 to 12 weeks for standard projects. Install is typically a 1 to 2 day crew visit from Burnaby.
