Should You Refinish or Replace Your Hardwood Floors?
Your hardwood floors look tired, and you’re staring down a decision: sand and refinish, or tear out and replace? The answer usually comes down to three things. How much wood is left to work with, how deep the damage actually goes, and what you’re willing to spend. Here’s a guide to answer you if you should refinish or replace your hardwoods floors and figure out which side of that line your floor is on, with a checklist you can walk through room by room.
How Do You Know If Your Hardwood Floor Can Be Refinished?
Every refinish involves sanding off the old finish and a thin layer of wood underneath it. Solid 3/4″ hardwood can usually be refinished 4 to 6 times over its life. Engineered hardwood has a much thinner wear layer (often just 1 to 6mm) and can typically only be sanded once or twice. If your floors pass the test below, refinishing is almost always the better move, financially and aesthetically.
The quick test: Pull a floor register or a threshold and look at the board’s edge. You want at least 1/4″ of wood above the tongue for a safe refinish. If you can already see nail heads or the tongue itself anywhere on the surface, that floor has been sanded to its limit.
What Damage Can Be Fixed by Refinishing?
Most of what makes a floor look “done” is actually surface-level and disappears completely with a sand and refinish:
- Scratches and scuffs, even ones that catch a fingernail
- Dull, worn, or hazy finish, the most common reason people call us
- Minor staining from spills or plant pots
- Small gaps under 1/8″, which are just normal seasonal movement
- Worn-through finish in entryways and hallways, as long as the exposed wood hasn’t taken on moisture damage
If your floor’s problems live on this list, refinishing will bring it back to like-new condition for a fraction of the cost of replacement.
What Damage Means You Need to Replace Your Floors?
Some damage goes deeper than sanding can reach:
- Widespread water damage: If more than 30% of the floor shows staining, warping, or delamination, board-by-board repair stops making sense
- Structural issues: Sagging, bouncing, or uneven floors point to a subfloor problem that needs to be fixed before any new surface goes down
- Termite damage: Even if it looks fine on top, tap suspect boards; a hollow sound means the wood is compromised underneath
- Floors sanded past their limit: If nail heads or tongues are visible, sanding again isn’t an option
Localized water or pet damage often doesn’t require full replacement. If it’s confined to one area, we can cut out and replace individual boards, then blend and refinish the whole surface, a fraction of the cost of tearing out the room.

How Much Does It Cost to Refinish vs. Replace Hardwood Floors?
This is usually where the decision gets made.
| What You're Comparing | Refinishing | Replacement |
|---|---|---|
| Cost per sq. ft. | $3–$8 | $8–$15+ |
| 1,000 sq. ft. project | $3,000–$8,000 | $8,000–$15,000+ |
| Timeline | 2–5 days | 5–10 days |
| Keeps your original floor | Yes | No |
| Fixes structural/subfloor issues | No | Yes |
Take in consideration that these values are approximate and not final data or estimates.
Even if a few boards need replacing during a refinish, typically $10 to $20 per board, the total is still well below full replacement in most cases. Refinishing is also far less disruptive: less time out of the room, less dust, and no demolition.
Should You Refinish or Replace Self-Assessment
Walk through this checklist for the room in question. It won’t replace an in-person inspection, but it’ll tell you which direction to expect.
| Question | If Yes | If No |
|---|---|---|
| Is there at least 1/4" of wood above the tongue? | Continue below | Replace |
| Is the damage mostly scratches, dullness, or minor staining? | Refinish | Continue below |
| Are the gaps between boards under 1/8"? | Refinish | Continue below |
| Do any boards feel soft, spongy, or bounce underfoot? | Replace | Continue below |
| Is water or pet damage limited to one small area? | Repair + Refinish | Continue below |
| Does more than 30% of the floor show warping or deep staining? | Replace | Refinish |
If you land on “repair and refinish” or you’re still unsure, that’s exactly the kind of call worth having a contractor make in person, measuring wear layer and checking the subfloor takes the guesswork out of it.

Common Scenarios We See in St. Louis Homes
Original strip oak in older homes (Webster Groves, Kirkwood, the Hill):
Most of these floors have been refinished once or twice and still have plenty of wear layer left. Worn finish near entries and light pet scratching are typical. Verdict: refinish.
Worn-through traffic paths:
The floor looks fine overall, but the route between the kitchen and living room has worn through to bare wood. A full sand and refinish evens it all out. A screen-and-recoat won't cut it once bare wood is showing. Verdict: refinish.
Water exposure near kitchens and baths (common in Central West End and Lafayette Square older homes with older plumbing):
If a slow leak has affected boards within 2 to 3 feet of the source and the rest of the floor is solid, board replacement plus a full refinish handles it. Widespread staining beyond that area usually points to replacement.
Historic homes with narrow strip oak (Clayton, Ladue):
These floors carry character worth preserving. When boards are sound, refinishing including matching historic stain tones, keeps the original material intact.
