A low per-square-foot price can hide skipped repairs, weak dust control, or an unnamed finish. These five checks make floor-refinishing bids comparable before furniture moves.

What to verify first
The Floor Decides the Scope.
A dull finish may need only a recoat. Bare wood, deep staining, loose boards, or a thin engineered wear layer can require full sanding, repairs, or replacement. The honest price starts with that diagnosis—not a square-foot guess.

The checklist
Five Things to Settle Before You Sign for Floor Refinishing.
02
Decide Repair, Recoat, or Full Refinish.
Ask the contractor to identify whether the damage sits in the coating, stain, wood, or floor structure. Each answer requires a different scope and price.
03
Check How Much Wood Is Left.
Solid hardwood and engineered flooring have different sanding limits. The crew should inspect remaining wear layer before promising a full sand.
04
Put Dust Control and Sanding Steps in Writing.
Tool-connected extraction, room isolation, edge work, and a deliberate grit sequence are part of the job—not optional cleanup.
05
Name the Finish and Cure Schedule.
Get manufacturer, product line, sheen, coat count, and separate milestones for socks, furniture, rugs, pets, and full cure.
Take the Checklist With You.

Red flags
Be Careful When the Bid Is Only a Square-Foot Number.
A complete refinishing estimate names repairs, prep, finish chemistry, access, exclusions, and cure time.
!
No Floor Diagnosis
A recoat price cannot solve bare wood, movement, or deep damage.
!
No Named Finish
“Polyurethane” without a product and coat count is not a specification.
!
Instant Return Promise
Dry-to-touch is not the same as ready for furniture, rugs, pets, or water.

Common questions
Floor Refinishing Questions, Answered.
A practical Bay Area planning range is roughly $4,500 to $8,000 for straightforward full sanding and refinishing, before major repairs, stairs, furniture handling, or specialty finishes.
Sometimes. Enough real-wood wear layer must remain above the tongue. The product or an exposed edge should be inspected before sanding is promised.
No. Modern extraction captures most sanding dust, but edges and airborne residue still require isolation and cleanup.
Follow the named finish system. Sock traffic, furniture, rugs, pets, and full cure have different milestones.
