Laminate vs. Solid Hardwood

It is if you will keep the floor long enough to refinish it. As planning ranges, laminate runs about $4–8 per sq ft installed and solid hardwood about $10–20. What the difference buys is a floor that can be sanded and refinished many times, per the NWFA, instead of replaced when its surface wears out. For a short ownership horizon or a rental, laminate is usually the better value.

Day to day, laminate's surface usually shows fewer fine scratches, and its AC class tells you how much abrasion it has proven it can take under NALFA LF 01. Hardwood scratches more readily, but the NWFA notes that most scratches sit in the finish, not the wood, and come out with a maintenance coat. A deep scratch in laminate is permanent until the plank is replaced; a deep scratch in hardwood can be sanded out.

No. Laminate's look is a printed decor under a clear surface layer, so there is no wood to sand. NALFA itself notes that, unlike hardwood, laminate does not require sanding or refinishing. A worn or damaged plank is replaced, so keep a box from the original run.

There is no fixed number. The NWFA says it depends on the skill of the contractor, the equipment, the thickness of the wear layer, and the flatness and condition of the floor. A professional removes generally 1/32 inch or less per sanding, while an untrained sander can remove much more and shorten the floor's life. Between sandings, a maintenance coat every 3–5 years, on the NWFA's schedule, puts off the next full sanding.

Both can work if spills are wiped up promptly, and neither tolerates a slow leak. Laminate edges swell where water sits in a joint, and LF 01's soak test allows up to 18% swelling at the residential level. Hardwood can cup, and the NWFA warns water can damage the finish and the wood. If the kitchen has a history of leaks, consider vinyl plank or tile instead of either.

On-grade, yes, with preparation. The NWFA says concrete must be moisture tested and moisture control in place before any solid wood floor is installed, and that solid wood should not go below grade unless the maker recommends it. In practice that often means a plywood subfloor over the slab or a glue-down product. Laminate floats over a slab with NALFA's 6-mil vapor barrier, and engineered wood is the usual choice for slabs and basements.

Wood takes on and gives off moisture with the air around it; the Wood Handbook calls it hygroscopic. When heat runs in winter, indoor air dries, boards shrink, and gaps open. The NWFA calls this normal and recommends keeping the home at 30–50% relative humidity and 60–80°F year-round, using a humidifier in winter to keep gaps small.

AC3 is the lowest class NALFA LF 01 certifies, at least 2,000 abrasion cycles, and it is fine for bedrooms and low-traffic rooms. For entries, hallways and family rooms, AC4 (at least 4,000 cycles) is the better pick. The AC class only rates surface wear. It does not make laminate refinishable or waterproof.

We cannot give you a reliable number, and you should be wary of anyone who does. What we can say is that buyers can see the difference: hardwood is real wood and can be refinished for the next owner, while worn laminate has to be replaced. If resale is the main goal, ask a local agent what comparable homes in your neighborhood have.
