ServiCover📌 Key Takeaway: Refinishing hardwood typically costs $3-$5 per square foot and is usually needed every 7-10 years in active homes — a fraction of the $8-$15 per square foot for new solid hardwood.
Refinish vs. Recoat vs. Replace
| Option | What It Involves | When to Choose It |
|---|---|---|
| Screen and recoat | Light abrasion and a fresh topcoat — no sanding to bare wood | Dull finish, light surface scratches |
| Full refinish | Sand to bare wood, optional stain, multiple finish coats | Deep scratches, worn finish, color change |
| Replace | Remove and install new flooring | Water damage, heavy rot, too thin to sand again |
The Refinishing Process
- Clear the room and remove base shoe molding if needed.
- Sand in progressive grits to bare wood.
- Stain (optional) — test samples on the actual floor first.
- Apply finish coats — typically water-based or oil-based polyurethane.
- Cure — wait before replacing furniture and rugs, per the finish manufacturer.
Water-Based vs. Oil-Based Finish
| Water-Based | Oil-Based | |
|---|---|---|
| Color | Clear; little ambering | Warm amber tone that deepens over time |
| Odor | Lower | Stronger |
| Dry time between coats | Faster | Slower |
Can Engineered Hardwood Be Refinished?
Often, yes — but only as many times as the top wood layer allows. Thin wear layers may only handle a screen and recoat. Ask a flooring pro to check before booking a full sanding.
Frequently Asked Questions
How long does hardwood refinishing take?
Many rooms take a few days from sanding to final coat, plus additional curing time before heavy furniture and rugs go back.
Is dustless sanding really dustless?
Systems that connect sanders to vacuums greatly reduce dust but rarely eliminate it entirely.
