Refinish vs Replace: Should You Save Your Hardwood Floors?

If the boards are solid, have thickness left above the tongue, and the damage is surface-level — scratches, gray UV wear, old finish, light staining — refinishing restores them at a fraction of replacement cost. This is the common case for original oak floors in older homes, including ones found hiding under carpet.

Replace when the wood is too thin to sand again, has been over-sanded in the past, shows deep water damage or rot, or when you want to change species, plank width, or layout. Severe pet damage, subfloor problems, and large missing sections can also tip the scales toward new installation.

Original hardwood is a selling point, especially in character homes. Refinishing preserves that and typically returns more than its cost at resale. Even when replacement is unavoidable, knowing why — thickness, damage, or a design change — keeps the decision (and the budget) clear-eyed.
