Hardwood stair refinishing cost depends on the number of stairs, tread condition, riser condition, railing work, landing work, repair needs, sanding difficulty, stain matching, finish type, access, drying time, and whether connected floors also need refinishing.
A simple stair refinish with limited wear may need a different plan than a staircase with deep scratches, chipped nosing, loose treads, old stain buildup, pet damage, water marks, or mismatched landings.
Stain matching can also affect the scope. Stairs often wear differently than floors because traffic concentrates in the centre of each tread. If the connected hardwood floors are older, faded, or previously stained, colour sampling and finish blending may be needed to create a better match.
Railing and handrail work can add another layer to the project. Some stair projects focus only on treads and landings. Others may include railings, posts, nosing, risers, or connected hallway flooring.
A final stair refinishing estimate depends on project details confirmed during review or an on-site visit.
