New construction & renovations Straight, L-shape or spiral Fully framed & finished

Custom Staircase Building in Ottawa

A new straight staircase runs $1,900-$5,000, and an L- or U-shape with a landing runs $2,200-$5,700, depending on total rise and finish. A new staircase is a structural build, not just a railing job – stringers, rise and run all have to be cut correctly before a single tread goes down. We build new staircases from the framing up for new construction, additions and full home renovations across Ottawa. Free on-site estimates from Railing Experts Ottawa.

Framing a stairwell guard during a staircase build

Recent Project in Kemptville

In Kemptville we framed a new stairwell guard in dimensional lumber as part of a staircase build. Our carpenter drilled through the framing to fasten the rail to its posts while the treads were still bare plywood.

Custom Staircase Building Built to Last Through an Ottawa Winter

New stringers are cut with a small tolerance for seasonal wood movement, so the staircase stays solid and squeak-free as humidity shifts through the year.

What Affects Your Custom Staircase Building Price

A new straight-run staircase typically runs $1,900-$5,000, while an L-shape or U-shape staircase with a landing runs $2,200-$5,700 – the exact number depends on total rise, run and finish material.

Staircase Styles We Build

Straight-run staircases

The simplest and most economical layout, one flight between two floors.

L-shape & U-shape staircases

A landing and turn to fit a stairwell that isn't a straight shot floor to floor.

Basement staircases

Framed and finished basement access stairs, from unfinished utility stairs to fully finished living-space staircases.

Custom stringers

Cut-to-fit stringers where an existing stairwell opening or rise doesn't match a standard layout.

Why Choose Us for Custom Staircase Building

Structural work, done right

We cut stringers to consistent rise and run – an uneven staircase is a fall hazard, not just a cosmetic issue.

New construction & renovation both

From a framed addition to a basement finishing project, we build the staircase from scratch.

One crew for structure and finish

The same team frames the staircase and installs the finished railing, so nothing gets lost between trades.

Our Process

How Our Custom Staircase Building Process Works

1

Confirm rise & run

Total floor-to-floor height and available stairwell footprint determine the stringer layout.

2

Frame the stringers

Stringers are cut and set first, then checked for level and consistent rise before treads go on.

3

Install treads, risers & railing

Treads, risers and the finished railing are installed once the structure is confirmed sound.

4

Final inspection

We test the finished staircase for level, consistent rise and secure railing before calling the job done.

Do you handle both the structural framing and the finished railing?

Yes, we build the staircase from the stringers up through the finished treads, risers and railing.

What's a typical rise and run for a residential staircase?

Ontario Building Code sets maximum riser height and minimum tread depth for a private staircase – we calculate the exact rise and run for your specific floor-to-floor height on site.

Can you build a staircase for a basement finishing project?

Yes, including converting an unfinished utility staircase into a fully finished one with proper treads, risers and railing.

How long does building a new staircase take?

A straightforward straight-run staircase can often be framed in a day or two, with tread, riser and railing finishing to follow.

Is there a warranty on custom staircase building?

Warranty terms for any job are set out in your written quote, job by job – we don't make blanket guarantees on this website, but every quote spells out exactly what's covered.
