How this calculator works

Estimate sanding and refinishing cost for hardwood floors with finish and stair allowances.

Area model

The calculator starts with room square footage and applies a finish-type cost range.

Stair allowance

Stairs are modeled separately because treads require slower edge work and hand detail.

Scope control

Board replacement, stains, furniture moving, and dust containment can change a real bid substantially.

Assumptions

Scope: Sanding, staining/finish labor, and common materials are included as planning ranges.
Exclusions: Board replacement, pet stains, lead concerns, furniture moving, and dust-control upgrades vary by bid.

FAQ

Does this include staining?

The range can cover common finishing work, but custom stain, samples, and color changes may add cost.

Are stairs priced by square foot?

Usually not cleanly. This calculator uses a per-tread allowance so stairs do not disappear into the floor area.

Can engineered hardwood be refinished?

Sometimes. It depends on wear-layer thickness and manufacturer guidance.
