Stair Framing GTA

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.
