Hardwood Flooring Cost Guide: Installation, Species & Calculator

Hardwood Flooring Cost by Species

The wood species is the biggest driver of material cost. Here's what to expect for unfinished and pre-finished solid hardwood:

Red Oak: $3–$7/sqft — the most common hardwood floor in the US. Excellent hardness, takes stain well, widely available.
Maple: $4–$8/sqft — very hard (harder than oak), light in color, resists dents well. Popular in kitchens and high-traffic areas.
Hickory: $4–$8/sqft — the hardest domestic species, dramatic grain, excellent durability.
American Walnut: $8–$14/sqft — rich dark chocolate tones, softer than oak, premium appearance.
Brazilian Cherry (Jatoba): $8–$14/sqft — extremely hard exotic wood, deep reddish tones.
Exotic species (teak, tigerwood, santos mahogany): $10–$20+/sqft

Solid vs. Engineered Hardwood

Solid hardwood is milled from a single piece of wood, typically 3/4 inch thick. It can be sanded and refinished multiple times over its lifespan (50–100+ years). It cannot be installed below grade (basements) or directly over concrete due to moisture sensitivity.

Engineered hardwood consists of a real hardwood veneer over a plywood core. It's dimensionally stable, can be installed below grade, and works over radiant heat systems. It can typically be sanded 1–3 times depending on veneer thickness. Cost is similar to solid — roughly $4–$12/sqft — but installation is more flexible.

Installation Methods & Labor Cost

Nail-down: Traditional method for solid hardwood over wood subfloors. Requires a pneumatic flooring nailer. Most durable long-term. Labor: $3–$5/sqft.
Glue-down: Used for engineered hardwood over concrete. Requires full-spread adhesive. Labor: $4–$6/sqft.
Floating: Planks click together and float over the subfloor without adhesive or nails. Faster installation. Used for engineered hardwood. Labor: $2–$4/sqft.

Total Project Cost

For a 400 sq ft living room using mid-range red oak at $5/sqft with nail-down installation at $4/sqft: Materials = $2,000 + Labor = $1,600 + Subfloor prep ($0.50–$1.50/sqft) + underlayment + transitions = total roughly $4,000–$5,500. Add 10% waste to your material order (buy 440 sq ft for a 400 sq ft room).

Pre-Finished vs. Site-Finished

Pre-finished hardwood comes with a factory-applied aluminum oxide finish. It's ready to use immediately after installation — no sanding, staining, or finishing on-site. The finish is extremely durable. Beveled edges between planks collect some dirt but are easy to clean.

Site-finished hardwood is sanded, stained, and finished after installation. It allows for custom stain colors, a perfectly flush surface between planks, and a seamless look. It adds $3–$5/sqft in labor and requires 3–5 days of floor being unusable during finishing.

Acclimation Period

Solid hardwood must acclimate to your home's temperature and humidity before installation. Store the unopened boxes in the room where they'll be installed for 3–5 days minimum. Engineered hardwood typically needs 24–48 hours. Skipping acclimation can cause gapping (too dry) or buckling (too humid) after installation.

Frequently Asked Questions

How much does it cost to install hardwood floors per square foot?

Total installed cost (materials + labor) typically runs $8–$20 per sq ft for most hardwood species and installation methods. Budget-friendly options like red oak with floating engineered installation can come in at $6–$10/sqft all-in. Premium solid hardwood with site-finishing can reach $20–$30/sqft for high-end species.

What's the cheapest hardwood flooring?

Red oak is the most affordable domestic hardwood, typically $3–$5/sqft for unfinished solid. Engineered red oak is similarly priced. Bamboo flooring (technically a grass but sold as a hardwood alternative) can be found for $2–$5/sqft and is very hard. Avoid extremely cheap laminate marketed as 'wood' — it's not hardwood.

Should I get solid or engineered hardwood?

Choose solid hardwood if you want maximum longevity, plan to refinish it in 20–30 years, and are installing over a wood subfloor above grade. Choose engineered hardwood for basements, over concrete slabs, over radiant heat, or in humid climates. Both use real wood — the difference is structural, not cosmetic.

How long does hardwood floor installation take?

A professional crew can install 300–500 sq ft of nail-down hardwood per day. A typical 1,000 sq ft floor takes 2–3 days. If site-finishing is required, add 2–3 more days for sanding, staining, and multiple coats of finish with drying time between coats. Total time from start to walking on the floor: 4–7 days.

Can hardwood be installed over concrete?

Solid hardwood should not be installed directly over concrete — moisture vapor from concrete will cause warping and cupping. Engineered hardwood can be glued down over concrete with moisture-barrier adhesive. Alternatively, install a plywood subfloor over the concrete first (using sleepers or adhesive) and then nail down solid hardwood on top.
