Why it matters
Stairs appear in almost every listing photo set, sit in the middle of the house, and are almost never priced by buyers. They are also one of the loudest era tells we have: a stained oak handrail with turned oak spindles says 1990s as clearly as a date stamp. Replacing that package with painted risers, a squared newel, and iron or square spindles is one of the highest-visual-impact changes in a house, and it is not cheap. Stairs are also where flooring budgets quietly grow. Carrying hardwood up a staircase is priced per step, not per square foot, and it costs several times what the same area costs on a flat floor. Carpet on stairs runs $4 to $6 per sq ft in labour alone, against $1.50 to $3.50 on the flat.
How to spot it
Carpeted treads over what may be hardwood underneath (worth asking about, exactly as with carpet elsewhere); orange-toned oak handrails and turned spindles; a painted or mismatched newel; scuffed, worn, or dished treads down the middle; and a railing that has been repaired rather than replaced.
What it costs
Toronto, 2026: refinishing existing stairs runs $50 to $125 per step, so a typical 13-step run lands in the low four figures. A comprehensive package that includes new railings, newel posts, spindles, and custom finishing runs $3,000 to $8,000. Railing refinishing alone, if the wood is sound, is far cheaper than replacement and is the value play.
What to do
Monitor. Price it per step, not per house. Ask what is under the stair carpet before you budget anything.
Education and triage, not a home inspection. Casaroo prices the look of a staircase. It does not certify that one is safe.
