One piece of timber, sandable for a century. Typical installed cost, durability, where it works and how to care for it.
Solid hardwood is exactly what it sounds like: 3/4" of a single species, tongue-and-grooved and nailed to a wood subfloor. Its defining advantage is renewability — a 3/4" floor can be sanded and refinished 5 to 8 times, meaning a well-maintained floor genuinely outlives the people who install it. Its defining limitation is moisture: wood moves seasonally with humidity, so solid plank is restricted to on- or above-grade installations over wood subfloors, and the NWFA calls for the interior to be held at 30–50% relative humidity and 60–80 °F.
A dent-resistance scale. Red oak = 1,290 and is the reference point. Hickory 1,820, hard maple 1,450, white oak 1,360, walnut 1,010, southern yellow pine 690, eastern white pine 380. Below ~1,000 expect visible denting in active households.
Plainsawn is standard and shows cathedral grain. Quartersawn and riftsawn cost 25–50% more, move roughly half as much seasonally and produce a tighter, straighter grain.
Prefinished uses aluminum-oxide UV-cured finish — harder and warrantied longer, with micro-bevels at each edge. Site finish gives a seamless, flat surface and lets you match stain exactly, but adds days and VOC exposure.
Wood must sit in the installed space, boxes opened, until its moisture content equilibrates. NWFA guidance is no more than 4% difference between flooring and subfloor for solid strip, and 2% for plank wider than 3 inches. Target 6–9% equilibrium moisture content, which corresponds to 30–50% RH at 60–80 °F. Skipping this is the number one cause of gapping and cupping.
Oil-modified polyurethane ambers over time and is easy to spot-repair. Water-based poly stays clear and cures fast. Hardwax oil penetrates rather than coating — repairable in place but needs periodic re-oiling.
| Thickness | 3/4" standard, 5/16" thin |
|---|---|
| Widths | 2¼"–7"+ (wider = more movement) |
| Refinishes | 5–8 over its life |
| Install | Nail/staple to wood subfloor |
Wide planks (6"+) look current but move more seasonally. In a dry climate, expect visible winter gaps unless you humidify.
Each feature paired with the benefit it delivers. A spec on its own tells you nothing about whether it is worth paying for.
Five to eight full sandings across its life. This is the only common floor that a new owner in 2075 could make look new again.
You can match the floor to the household: hickory at 1,820 for a busy family, walnut at 1,010 where looks lead and traffic is light.
The finish is applied after installation, so the surface is dead flat with no micro-bevels, and the stain can be matched to existing floors exactly.
Mechanically fastened rather than glued or floating, which is why it feels solid underfoot and stays silent when the room is walked across.
The only flooring category buyers consistently pay more for. Refinishing before a sale costs a fraction of replacement and shows as new.
Drawn from the same ratings used everywhere else on this site, so this cannot flatter the product beyond what the comparison table says.
The specifications below decide how this floor performs. Ask for them in writing — a sample board and a price per square foot do not tell you any of it.
Solid Hardwood runs $9.00–$22.00 per square foot installed in 2026 — $5.00 to $14.00 for material and $4.00 to $8.00 for professional labor. Spread across an expected 50 to 100 year service life that works out near $0.21 per square foot per year. Regional variation of 20 to 40% is normal, and demolition, subfloor prep and trim are extra.
50 to 100 years, assuming it went into an appropriate room over a properly prepared substrate and gets the maintenance it needs. Wide planks (6"+) look current but move more seasonally. In a dry climate, expect visible winter gaps unless you humidify.

Sweep or dust-mop daily in traffic areas — grit is what abrades finish. Damp-mop with a wood-specific cleaner, barely moist. Critically: never wet-mop or use a steam mop — steam drives moisture into the seams.
