Quick answer

A staircase renovation in Ontario typically costs $2,500 to $12,000. Refinishing treads and installing new railings sits at the low end, replacing treads and risers with hardwood runs in the middle, and a full rebuild with new stringers, glass, or iron railings reaches the top. The building code sets the rules for rise, run, and railing height.

Staircase renovation cost by scope

A staircase can be updated at several levels, from a quick refinish to a full rebuild. Here is what each costs in Ontario.

Staircase renovation cost by scope (Ontario)
ScopeTypical cost
Refinish treads and paint risers$1,200 to $3,000
New railing and balusters only$2,500 to $6,000
New hardwood treads and risers$3,500 to $8,000
Add glass or iron railings$4,000 to $10,000
Full rebuild (new stringers and stairs)$8,000 to $18,000+

The biggest cost jumps come from replacing the structural stringers and from premium railings like frameless glass or custom iron.

Popular staircase upgrades

A staircase is often the first thing you see inside a home, so small changes have a big visual payoff. Popular Ontario upgrades include:

  • Stained hardwood treads with crisp white-painted risers
  • Iron or metal balusters in place of dated wood spindles
  • Frameless or framed glass railings for a modern, open look
  • Open risers to let light through
  • A new handrail profile and freshly painted stringers
  • A stair runner for warmth, comfort, and quiet

Ontario code rules for stairs

Stairs are a common cause of injury, so the Ontario Building Code sets firm rules. When stairs or railings are rebuilt, they generally must meet current requirements, which include:

  • Consistent rise and run within set limits, so steps are even
  • Guards and railings at a minimum height (commonly around 900 mm for interior stairs, higher for landings and drops)
  • Baluster spacing tight enough that a small child cannot pass through, generally under 100 mm
  • Adequate headroom above the stairs
Bringing stairs to code matters. Older homes often have stairs that no longer meet current rules. A renovation is the right time to make them safe as well as beautiful.

Do you need a permit for stair work?

Cosmetic work like refinishing treads, painting, or swapping balusters usually does not need a permit. Rebuilding the staircase, changing its configuration, or altering the structural stringers does require a building permit, because it is structural and safety-related. We confirm what your project needs and handle the permit if required. See our permit guide.

Do staircase updates add value?

Because the staircase is usually front and centre in the entry, updating it lifts the whole first impression of a home, which matters at resale. It pairs naturally with new flooring, so many homeowners do both together. See our flooring comparison and our guide to renovations that add the most value.
