Opening Geometry Control
Stair openings need the right length, width, trimmers, headers, and floor-edge support. Timberr frames the rough opening so finished stairs can meet the design without cutting back the floor later.

Why Timberr Framing
Stair Framing in Oshawa, done right
Landing Bearing Support
Intermediate landings and stair turns concentrate loads into walls, posts, or beams. We frame landings and supports so they do not rely on weak partitions or finish materials for structure.
Headroom And Clearance
Stairs fail functionally when beams, ducts, or openings steal headroom. Timberr coordinates stair framing with floor systems and bulkheads before those conflicts become expensive field changes.
Guard And Rail Backing
Guards, handrails, and newel posts need solid fastening points. We install backing and edge framing where railing hardware will land, not after drywall or finished treads are in place.
Our Process
Our Process
Stair framing creates the structural openings, landings, walls, stringer support, headers, guards, and backing required for interior or exterior stairs in homes, additions, suites, and commercial spaces. Timberr Framing coordinates with the engineer, architect, GC, stair supplier, and railing trades so stair geometry, bearing, headroom, and inspection details match the drawings and Ontario Building Code.
- 01 Send your inquiry, plans, drawings, or a description of the build.
- 02 We review the plans and assess the Oshawa site, then quote and schedule the crew.
- 03 Our crew frames the structure on site, to your drawings and the Ontario Building Code.
- 04 We leave it plumb, square, and ready for the framing inspection and the trades that follow.
Local Context
Stair Framing in Oshawa
What Affects Your Stair Framing Quote
Stair framing is unforgiving geometry: rise, run, headroom, and landing bearing all have to agree with the Ontario Building Code and with each other. Timberr Framing lays out the stair opening from the drawings before framing around it, confirms landing bearing points, and checks headroom clearance at every tread before the rest of the floor closes in around the stairwell.
Quotes shift with stair type (straight run, switchback, winder), floor-to-floor height, and how much guard and rail backing the design calls for. Timberr frames the opening geometry first so trim, guards, and finish stairs aren't fighting an out-of-tolerance rough opening later, and coordinates directly with the GC on when the stairwell needs to be inspection-ready.
Timberr Framing coordinates stair framing timing with the GC so the opening is ready exactly when the stair supplier or finish carpenter needs it, avoiding a rough opening that sits unfinished and exposed for weeks.
We also confirm tread and riser dimensions against the architectural drawings before framing the opening, so the finished stair meets Ontario Building Code rise-and-run requirements.
