Hardwood Flooring Cost: Solid vs. Engineered and What Drives the Price
Updated May 2026 · 8 min read · Sources: NWFA, HomeGuide, Angi, BLS, Hallmark Floors
Hardwood flooring costs $8–$28/sq ft installed — a range wide enough to be nearly useless without context. The number you land on depends on five decisions: solid vs. engineered, species, plank width, finish type, and installation method. This guide breaks down each one so you know exactly what you are paying for.

Solid vs. engineered hardwood: the core difference
Solid hardwood is a single piece of wood milled from top to bottom — typically 3/4" thick. Engineered hardwood is a plywood or HDF core with a real wood veneer on top, ranging from 3/8" to 3/4" total thickness. From the surface they are visually identical. The differences matter for where you install, how it reacts to moisture, and how many times it can be refinished.
| Factor | Solid Hardwood | Engineered Hardwood |
|---|---|---|
| Material cost | $3–$15 / sq ft | $4–$12 / sq ft |
| Installed total | $8–$28 / sq ft | $7–$22 / sq ft |
| Thickness | 3/4" (standard) | 3/8"–3/4" |
| Refinishable | Yes — 5–7 times | Yes — 1–3 times (thin veneer) |
| Lifespan | 50–100 years | 25–50 years |
| On concrete slab | Not recommended | Yes (glue-down or float) |
| Over radiant heat | Limited / risky | Yes (manufacturer-specific) |
| Basement install | Not recommended | Yes (with low moisture) |
| Humidity tolerance | Low — expands/contracts | Moderate — more stable |
| Installation methods | Nail-down, glue-down | Float, nail, staple, glue |
Cost by species — what you are actually paying for
Species drives material cost more than any other single factor. It also determines hardness (resistance to dents), color, and grain character. The Janka hardness rating measures the force required to embed a steel ball halfway into the wood — a useful proxy for scratch and dent resistance.
| Species | Material / sq ft | Installed avg | Janka | Character |
|---|---|---|---|---|
| Red oak | $3–$7 | $11–$15 | 1,290 | Warm pinkish tone; open grain; very widely stocked |
| White oak | $4–$10 | $13–$18 | 1,360 | Cooler, grey-tan tone; tighter grain; excellent for staining; trending strongly |
| Hard maple | $4–$10 | $13–$18 | 1,450 | Very hard; pale, minimal grain; preferred for light, Scandinavian looks |
| Hickory | $5–$11 | $14–$20 | 1,820 | Dramatic two-tone grain; hardest domestic species; hides wear well |
| American walnut | $7–$15 | $18–$26 | 1,010 | Dark chocolate tones; softer than oak but premium look; dents more easily |
| Brazilian cherry (Jatoba) | $6–$13 | $16–$24 | 2,820 | Extremely hard; reddish; darkens significantly with UV over 1–3 years |
| Ash | $4–$9 | $12–$18 | 1,320 | White oak alternative; open grain; good stainability; increasingly popular |
| Teak | $8–$20 | $20–$30 | 1,155 | Naturally water/oil resistant; premium pricing; difficult to glue-down |
For families with dogs: Choose a species with a Janka rating above 1,200 and a wire-brushed or hand-scraped surface texture. The texture hides micro-scratches from pet nails. High-gloss finishes on soft species (walnut, pine) show every mark — avoid this combination.
Plank width: how it affects both cost and look
Narrow strip hardwood (2.25"–3.25") is the traditional, most affordable option — faster to mill, fewer unusable boards, and faster to install. Wide-plank hardwood (5"–9"+) has become the dominant trend in new construction and renovation, but it adds meaningful cost in two directions: higher material price per square foot and more labor to keep it flat.
| Width | Material premium | Labor premium | Notes |
|---|---|---|---|
| 2.25"–3.25" (strip) | Base price | Base rate | Traditional; fastest install; most stable |
| 4"–5" (standard wide) | +10–20% | +5–10% | Most popular width in 2026; good balance of look and stability |
| 5"–7" (wide plank) | +20–40% | +10–20% | Open, modern feel; requires drier, more stable subfloor |
| 7"–9" (extra wide) | +40–70% | +15–25% | Maximum visual impact; needs glue assist even with nail-down; humidity-sensitive |
| 9"+ (reclaimed/custom) | +50–150% | +20–40% | Specialty product; often reclaimed barn wood; unique grain and character |
Wide-plank solid hardwood over 5" has a higher rate of cupping and gapping in humid climates. Most flooring contractors require documented moisture testing before installing wide-plank solid hardwood. Engineered hardwood handles wide widths significantly better due to its dimensionally stable core.
Prefinished vs. site-finished: a $2–$4/sq ft decision
Prefinished hardwood
No extra cost — finish is included in material price
Pros
- Walk on it the same day of installation
- Factory finish is highly durable (aluminum oxide coat)
- Faster installation = lower labor
- Predictable outcome; no fumes in your home
Cons
- Beveled micro-edges between planks collect dirt
- Cannot customize sheen level or stain on-site
- Color/sheen locked to manufacturer spec
- Hard to blend repairs seamlessly
Site-finished hardwood
Adds $2–$4/sq ft in labor (sanding + 3 finish coats)
Pros
- Seamless, bevel-free surface — boards look like one piece
- Custom stain color applied on-site
- Repairs and future refinishes blend perfectly
- Design standard for high-end projects
Cons
- Off the floor 2–3 extra days during finishing
- Fumes require ventilation and temporary exit
- Higher labor cost
- Finish durability slightly lower than factory aluminum oxide
Installation method cost differences
How the floor is fastened to the subfloor affects both labor cost and which products are even possible in your situation. Solid hardwood can only go on wood subfloors via nail-down or glue. Engineered hardwood opens up all three methods and can go over concrete.
| Method | Labor / sq ft | Sq ft / day | Works on concrete | Notes |
|---|---|---|---|---|
| Nail / staple down | $3.50–$6.50 | 80–150 | No | Standard for solid hardwood over plywood; pneumatic nailer required; very secure; slight hollow sound |
| Glue down | $5.50–$9.50 | 60–100 | Yes | Required on concrete; no hollow sound; most rigid feel; hardest removal; trowel + urethane adhesive |
| Floating (click-lock) | $3.00–$5.50 | 200–350 | Yes (with moisture barrier) | Easiest install; slight hollow sound underfoot; not recommended for solid HW wider than 3" |
| Glue + nail (combo) | $6.00–$10.00 | 60–90 | No | Used for wide-plank solid HW on plywood; glue stabilizes; nails hold ends; most secure method |

Add $2,000–$8,000 for old floor removal + subfloor leveling on a 1,500 sq ft project if needed. Add $1,400–$4,200 for a 14-step hardwood staircase.
Hidden costs most quotes omit
Acclimation (3–5 days before installation)
Solid hardwood must sit in your home — in its final room, stacked loosely, with HVAC running — for 3–5 days before installation. If the installer does not mention this, ask. Skipping it causes cupping, gapping, and squeaks within months. This adds nothing to material cost but affects scheduling: you need delivery 4–6 days before the install date.
Moisture testing ($75–$200)
A professional installer will test the moisture content of your subfloor (and the wood itself) with a moisture meter before installation. Acceptable range: wood at 6–9% MC; concrete slab below 3 lbs/1,000 sq ft (calcium chloride test). If subfloor moisture is too high, a moisture barrier or full remediation is required before any wood floor can go down.
Old floor removal ($2–$5/sq ft)
If you have glued-down vinyl, old hardwood secured with adhesive, or tile, removal costs $2–$5/sq ft and can add $3,000–$7,500 to a 1,500 sq ft project. Floating floors (LVP, laminate, old floating hardwood) come up faster at $1–$2.50/sq ft.
Subfloor repairs ($2–$7/sq ft)
Solid hardwood over plywood requires the subfloor to be flat within 3/16" over 10 feet. It also requires a minimum subfloor thickness of 3/4" (nail-down) or 1/2" (staple). If you have thinner subfloor panels or soft spots, repairs add $2–$7/sq ft — sometimes more for structural issues.
Stair installation ($100–$300 per step)
Stairs are almost always priced separately. A full 14-step hardwood staircase in a matching species with tread-only overlay runs $1,400–$2,800; full tread and riser replacement is $2,100–$4,200. Always confirm whether stairs are included in your quote.
