Refinish Hardwood Floors or Replace Them?

Worn hardwood is not automatically a tear-out. It also is not automatically a cheap recoat. The honest split is: is the problem in the finish, in the wood, or in a wear layer that is already too thin to sand?

This page is general guidance. Wilke quotes sanding, staining, screen-and-recoat, and board repair when the floor can take it, and hardwood installation when it cannot. We do not promise that every worn floor can be refinished. Prices stay off this page on purpose.

Recoat, full sand, or replace

Screen-and-recoat (or buff-and-recoat)

If the finish is dull or lightly scratched but the wood itself is not damaged, a screen-and-recoat may be an option. Occupied rooms like this option because it is less dust and less downtime. It will not hide stains that went into the wood, deep scratches, or a color change.

Full sand and finish

The finish is gone in paths, the color is wrong, or the surface is rough. A sander cuts back to wood, then stain and clear coats go on. This only works if enough wear layer remains — especially on engineered floors.

Replace

Boards are loose, delaminated, rotten, or sanded so many times the tongue is the story. Moisture moved the floor and it has not come back. Or the product was a thin veneer that will not survive another pass. Replacement can be a room or a whole floor; it is still a different job from refinishing.

Solid versus engineered

Solid hardwood can often be refinished multiple times depending on its thickness and previous sanding. Engineered floors have a real-wood wear layer over a core. That wear layer is the whole budget.

The National Wood Flooring Association’s Sand and Finish Guidelines, as quoted in NWFA’s own write-up, generally treat remaining wear thickness of less than about 3/32 inch (2.5 mm) as a point below which sanding is not recommended. That is a common threshold, not a measurement of your floor. Manufacturer or product information and an on-site assessment control. We will not diagnose remaining wear from a phone photo alone.

Moisture and movement

Cupped or moisture-moved floors should not be sanded flat until the moisture problem is corrected and the wood and subfloor have had time to equalize. Sanding a wet, cupped floor flat is how you get a floor that dishes the other way when it dries. Leaks, slabs without a barrier, and rooms that were never climate-controlled belong in the assessment, not in a “we’ll make it look new” sentence.

What we need to quote

Photos of the field, the worst traffic lane, a close-up of a vent or threshold if you can pull the cover, stairs if they are in scope, and whether the house is occupied. Flooring work is quoted from that, then confirmed on site when the photos are not enough. Related make-ready work for rentals lives on the turnover checklist.
