Hardwood Floor Restoration: When to Sand, When to Screen, and When to Call a Pro

Hardwood floors are one of the most durable and beautiful elements of a home — and one of the most frequently mishandled when it comes to restoration. The instinct when floors look tired is to sand them back to bare wood and start fresh. But a full sand is a significant undertaking, and in many cases it's more than what's needed. Understanding your options leads to better results and fewer unnecessary disruptions.

Screen and recoat: the lightest touch

A screen and recoat involves lightly abrading the existing finish with a floor buffer and applying a fresh coat of finish on top. No sanding to bare wood, no stain change — just a refreshed surface. This works well when the finish is dull, slightly scratched, or showing wear in high-traffic areas, but the floor isn't deeply damaged. It's fast (typically one day), affordable, and adds years of life to a floor that doesn't yet need more significant work. The key limitation is that it doesn't remove deep scratches, stains in the wood, or significant damage — it only works on surface-level finish wear.

Full sand and refinish: when it's necessary

A full sand means running a drum or orbital sander over the entire floor, removing all existing finish and a thin layer of wood, then staining (if desired) and applying fresh finish from scratch. This is the right approach when there are deep scratches, stains, gouges, or damage that goes into the wood itself; when the floor has been recoated multiple times and the finish has become thick and yellowed; or when you want to change the color or sheen of the floor. A properly maintained solid hardwood floor can typically be sanded 5 to 7 times over its lifetime before the boards become too thin. Engineered hardwood can usually be sanded once or twice, depending on the veneer thickness.

Spot repair vs. full-floor work

For localized damage — a stain from a pet, a burn mark, a deep gouge in one area — spot repair is sometimes possible. A skilled craftsperson can sand, fill, stain, and refinish a specific area and blend it with the surrounding floor. The challenge is color and sheen matching: an aged floor has a patina that's difficult to replicate exactly. In some cases, spot repairs are barely visible; in others, a difference remains. Our floor restoration team will tell you honestly which approach will give you the best result.

Preparing for floor restoration

Regardless of the approach, floor work requires clearing the room completely and, for full sanding, making arrangements to be out of the space for at least 24 to 48 hours while the finish cures. Oil-based finishes are more durable and have a warmer tone but require longer cure times and produce more fumes. Water-based finishes cure faster, have little odor, and dry clear. The National Wood Flooring Association publishes detailed installation and maintenance guidelines that are worth reading if you're planning a restoration project.

Maintaining restored floors

After restoration, hardwood floors should be swept or vacuumed regularly, cleaned with a pH-neutral wood floor cleaner, and protected with felt pads under furniture legs. Avoid wet mopping — water is wood's enemy. With proper care, a professionally refinished hardwood floor should look excellent for 8 to 12 years before another recoat is needed.
