Why mono stringer staircase work in Coquitlam
Custom mono stringer staircases, a single central steel beam with cantilevered treads, engineered for residential and light commercial projects.
Coquitlam's mono stringer market breaks neatly into two halves. Burke Mountain and Westwood Plateau drive the new-build custom home demand, these are some of the most active custom home neighbourhoods in the Tri-Cities right now, and the homes going in on Burke Mountain almost always include a mono stringer or floating stair as the centrepiece of the open-concept main floor. Typical Burke Mountain projects target $22,000, $35,000 budgets with oak or walnut treads and cable railings. The other half of the market is the 1950s, 1980s housing stock in Maillardville, Ranch Park, and Eagle Ridge, where a mono stringer replacement is part of a broader renovation targeting the $18,000, $26,000 range. Our Burnaby shop is 15 to 25 minutes up Lougheed Highway from most Coquitlam sites, and we have been regular subcontractors on custom home projects for several Tri-Cities builders over the past decade. The coordination rhythm is similar to Burnaby, we work with the builder's framing crew to get the opening dimensions right and schedule the install to fit the sequence of trades on site.
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.

How a mono stringer project moves through our shop
1. Site visit and design review. Measurements, floor-to-floor height confirmation, opening-dimension planning, and review of structural connection points.
2. Structural engineering. Sealed drawing from a registered P.Eng., stringer section sizing, connection details, load calculations per NBC 2020.
3. Shop drawings. Fabrication drawings coordinating with the architect and GC. Opening dimensions, tread layout, railing integration, finish schedule.
4. Fabrication. Steel cut, welded, and jigged at our Burnaby shop under CWB supervision. Stringer section, tread brackets, and railing integration completed in the shop.
5. Finishing. Powder coat on a prepared substrate. Matte black (RAL 9005) is the default. Custom colours available. Clear-coat over raw steel for industrial looks.
6. Installation. Crane or hand-set depending on site access. Base plate bolted to slab or embedded in floor. Tread installation and railing integration complete the stair.

FAQs
Mono Stringer Staircase questions from Coquitlam clients
Answers to the questions we hear most often from Coquitlam homeowners, architects, and GCs on mono stringer projects.
How much does a mono stringer staircase cost in Coquitlam?
Mono stringer staircase cost in Coquitlam depends on configuration, tread material, railing type, and whether the project is a new build or a renovation into existing framing. New custom homes on Burke Mountain and Westwood Plateau typically spec oak treads and cable or steel railings; renovation projects in Maillardville, Ranch Park, and Eagle Ridge usually involve demolition of the original stair plus floor-connection reinforcement, which affects overall scope. Our Burnaby shop is 15 to 25 minutes up Lougheed Highway. <a href="/request-a-quote/">Request a quote</a> with your site dimensions and we'll follow up with project-specific pricing.
Do you work with Tri-Cities custom home builders on Burke Mountain projects?
Yes, we're regular subcontractors for several Tri-Cities builders active in Burke Mountain, Westwood Plateau, and Central Coquitlam. We coordinate shop drawings with the builder's framing package, schedule mono stringer installation to fit the main construction sequence, and handle structural engineering submittals on behalf of the builder. On multi-project builders we can stage fabrication across concurrent projects.
What permits are required for a mono stringer staircase in Coquitlam?
The City of Coquitlam requires a building permit for structural staircase work. A mono stringer is a structural element so the permit application includes a sealed drawing from a registered P.Eng. Permit processing at the City of Coquitlam runs 4 to 8 weeks for a standard residential scope. We coordinate the engineering and provide the drawings your permit application needs, this is our standard scope on all mono stringer projects.
Can you handle renovation mono stringer projects in Maillardville or Ranch Park character homes?
Yes. Many of our Coquitlam renovation projects are in the older Maillardville, Ranch Park, and Eagle Ridge neighbourhoods where homes from the 1950s, 1980s are getting full interior updates. The mono stringer is almost always replacing an original carriage stair, which means we also handle demolition of the existing structure and floor-connection reinforcement. Total project timeline for a renovation scope is 10 to 14 weeks from design meeting through install.
How long is the typical timeline for a Coquitlam mono stringer project?
From the initial design meeting to the finished installed stair, expect 10 to 14 weeks. Engineering and shop drawings run 3 to 5 weeks, fabrication takes 3 to 4 weeks, and installation is a 1 to 2 day on-site visit. For new-build custom home projects we schedule fabrication to match the builder's timeline, with the stair installed shortly after drywall is complete so floor framing and landing conditions are locked in.
What tread and railing combinations do Coquitlam custom home builders typically spec?
White oak treads with cable railings are by far the most common combination on Burke Mountain and Westwood Plateau projects, it's the modern-default spec for Metro Vancouver custom homes in this price range. Steel picket railings show up on more traditional designs in Maillardville and Ranch Park renovations. Walnut treads appear on the higher-end Burke Mountain builds where the interior design is skewing darker.
