"Hardwood flooring" covers an enormous range of products. The same room can look traditional or strikingly modern depending on species, plank width, grade, and finish. Understanding the main categories helps you make confident decisions — and get quotes that compare apples to apples.
Solid vs. engineered hardwood
This is the first and most important fork in the road. Both are real wood; they differ in how they're built.
- Solid hardwood — a single, solid piece of wood (typically 3/4" thick). It can be sanded and refinished many times, making it extremely long-lived, but it's more sensitive to humidity and is best installed above grade over a wood subfloor.
- Engineered hardwood — a real hardwood wear layer bonded to a multi-ply or HDF core. The cross-layered construction resists moisture-driven movement, so it can go over concrete slabs and in below-grade or humid spaces. A thicker wear layer means it can still be refinished, just fewer times than solid.
Popular wood species and their character
Species drives color, grain, hardness, and price. A few of the most common:
| Species | Look | Notes |
|---|---|---|
| White Oak | Cool, neutral, tight grain | Versatile, hard, takes stain beautifully — today's most popular choice |
| Red Oak | Warm, pinkish, strong grain | Classic, affordable, hides wear well |
| Hard Maple | Pale, smooth, subtle grain | Very hard; can be blotchy with dark stains |
| Hickory | High contrast, rustic | Among the hardest domestics; great with pets/kids |
| Walnut | Rich chocolate-brown | Softer but luxurious; stunning in formal spaces |
| Heart Pine | Amber, characterful | Reclaimed/antique looks; historic Charleston favorite |
Plank width and layout
Width changes the whole feel of a floor. Narrow strip flooring (under 3") reads traditional; wide planks (5"–8"+) feel current and show off the wood's grain. Mixed-width installs and patterns add character.
- Strip flooring: 1.5"–2.75" wide — classic, formal.
- Plank flooring: 3"+ wide — modern, popular, fewer seams.
- Patterns: herringbone and chevron for a high-end, designer statement.
Grades: how much character do you want?
Grade refers to the amount of natural variation — knots, color streaks, and mineral marks — allowed in the boards, not the quality of the wood.
- Clear / Select — minimal knots and color variation; clean and uniform.
- Common #1 / Character — moderate variation and small knots; warm and lived-in.
- Common #2 / Rustic — lots of character, color swings, and knots; great for farmhouse and reclaimed looks.
Prefinished vs. site-finished
- Prefinished — sanded, stained, and sealed at the factory under controlled conditions, often with very hard aluminum-oxide finishes. Faster install, no on-site dust or fumes, ready to walk on right away. Seams have small micro-bevels.
- Site-finished (unfinished) — installed raw, then sanded and finished in your home. Gives a perfectly smooth, seamless surface and total control over stain color, but takes longer and involves sanding dust and dry time.
Matching existing floors
If you're extending or repairing an existing floor, site-finishing usually produces the most seamless blend because we can custom-match the stain and sheen on-site.
Key Takeaways
- Solid wood lasts longest and refinishes most; engineered wood is more moisture-stable.
- Species sets the color, hardness, and price; White Oak is today's most popular.
- Wider planks feel modern; narrow strips feel traditional.
- Prefinished installs fast and clean; site-finished gives a seamless, fully custom result.
Frequently Asked Questions
Yes. Engineered hardwood has a genuine hardwood wear layer — the surface you see and walk on is real wood. The difference is the stable, multi-layer core beneath it, which resists humidity-driven movement better than solid wood.
