When Michigan homeowners walk into our Rochester Hills showroom asking for hardwood flooring, most start by saying they want solid over engineered. The assumption is that solid must be better — it's the real thing, after all. But once you understand how each floor is actually built, the choice becomes a lot more nuanced than that.
The honest answer is that both solid and engineered hardwood are real wood floors. The difference lies in how they're constructed, where they perform best, and what trade-offs you're willing to make. Here's everything you need to know before you decide.
What Is Solid Hardwood Flooring?
Solid hardwood is exactly what it sounds like — a single, solid piece of wood milled from top to bottom. The standard thickness is 3/4 inch, and the usable wear layer above the tongue-and-groove is roughly 1/4 inch. That's the wood you can sand and refinish multiple times over the life of the floor.
Because it's one continuous piece of wood, solid hardwood responds directly to changes in temperature and humidity. Wood expands when it absorbs moisture and contracts when it dries out. In Michigan, where we swing from humid summers to dry, heated winters, that movement is real and needs to be accounted for during installation.
Solid hardwood is typically nailed or stapled to a wood subfloor. It is not recommended for installation over concrete slabs or below grade — the moisture exposure is too unpredictable for a solid plank.
What Is Engineered Hardwood Flooring?
Engineered hardwood has a real wood veneer on top — the same species and grain you'd see in solid hardwood — bonded to a core made of multiple layers of plywood, HDF, or other engineered material. The cross-ply construction of those core layers is what gives engineered hardwood its dimensional stability.
Because the core layers run in alternating directions, they resist the expansion and contraction that affects solid wood. This makes engineered hardwood a better choice for concrete slabs, basements, and rooms with radiant heat — situations where solid hardwood would be risky.
The National Wood Flooring Association (NWFA) classifies engineered hardwood as real wood flooring. The wear surface is genuine hardwood, and it looks, feels, and sounds like wood underfoot.
The Veneer Thickness Question
Not all engineered hardwood is created equal, and the single most important spec to understand is veneer thickness. This determines how many times you can sand and refinish the floor over its lifetime.
- Under 2mm: Treat as a wear surface only — refinishing is not practical.
- 2–3mm: Limited refinishing potential; suitable for most homes.
- 4–4.5mm: One or two careful refinishes are possible; a solid long-term choice.
- 5–6mm: Premium tier — refinishing life approaches what solid hardwood offers.
A 6mm engineered floor and a 3/4-inch solid floor are much closer in refinishing potential than most people realize. The gap between cheap engineered and premium engineered is far wider than the gap between premium engineered and solid.
Side-by-Side: Engineered vs Solid Hardwood
| Factor | Solid Hardwood | Engineered Hardwood |
|---|---|---|
| Construction | Single piece of wood | Real wood veneer over engineered core |
| Typical thickness | 3/4" | 3/8" to 3/4" |
| Plank widths | Up to about 5" | 3" to 12"+ |
| Dimensional stability | Lower | Higher |
| Refinishing potential | Several sandings over decades | Depends on veneer thickness |
| Over concrete / below grade | Not recommended | Often approved |
| Radiant heat | Risky for most products | Better option; check specs |
| Resale perception | Strong | Strong for premium; weaker for thin veneer |
| Price range | Budget to premium | Budget to premium |
Where Each Floor Performs Best
Solid Hardwood Is the Right Choice When:
- You have an above-grade wood subfloor
- You want the longest possible refinishing life
- You prefer traditional plank widths (2.25" to 5")
- You plan to stay in the home for decades and want a floor that can be renewed
- You maintain stable indoor humidity year-round (30–50% relative humidity)
Engineered Hardwood Is the Right Choice When:
- You're installing over a concrete slab or in a basement
- You want wide planks (6" and above)
- You have radiant heat
- Your home experiences significant humidity swings
- You want more installation flexibility (floating, glue-down, nail-down)
Michigan Climate Considerations
Michigan's climate creates real challenges for hardwood flooring. Our winters are cold and dry — indoor heating pulls moisture out of the air, and wood floors shrink in response. Summers bring humidity that causes wood to expand. This seasonal cycle is normal, but it means your floor needs to be matched to the conditions.
For Michigan homes with wood subfloors and stable indoor humidity, solid hardwood is an excellent long-term investment. For homes with concrete slabs, finished basements, or radiant heat systems, engineered hardwood is the smarter choice. Either way, proper acclimation before installation is essential — the floor needs time to adjust to your home's specific temperature and humidity before it goes down.
Installation Methods
How your floor is installed affects how it feels and sounds underfoot. Solid hardwood is typically nailed or stapled to a wood subfloor — this creates a firm, solid feel. Engineered hardwood offers more options:
- Nail-down or staple-down: Same as solid; works on wood subfloors.
- Glue-down: Works over concrete or wood; eliminates the floating feel.
- Floating (click-lock): Fastest install; most sensitive to subfloor flatness.
- Glue-assist: Adhesive at strategic points reduces movement and hollow sound.
The hollow sound some people associate with engineered hardwood almost always comes from a floating installation over an uneven subfloor. A glued or nailed engineered floor feels just as solid as solid hardwood.
What About Resale Value?
Solid hardwood carries the strongest resale perception in most markets, including Michigan. Buyers recognize it as a premium feature. Premium engineered hardwood — particularly wide-plank white oak from respected manufacturers — also performs very well with buyers.
What can hurt resale value is thin-veneer engineered flooring that looks worn and signals an upcoming replacement cost. If you're buying engineered with resale in mind, invest in a product with at least a 4mm veneer.
Quick Verdict
The real question isn't "engineered or solid?" — it's which grade of engineered you're comparing, and whether the floor fits your room, your subfloor, and your timeline. A premium engineered floor and a quality solid floor are both excellent long-term investments. A budget engineered floor is a different product entirely.
At Quality Hardwoods of Michigan, we carry both solid and engineered hardwood from trusted brands including Mullican, Sheoga, Provenza, and Appalachian. Our team can walk you through the options for your specific situation — subfloor type, room conditions, budget, and design goals.

Frequently Asked Questions
Is engineered hardwood real wood?
Yes. The wear layer is genuine hardwood — the same species and grain as solid hardwood. The NWFA classifies engineered hardwood as real wood flooring.
Can engineered hardwood be refinished?
It depends on the veneer thickness. Under 2mm, refinishing is not practical. At 4mm or above, most products can handle at least one careful refinish. At 5–6mm, the refinishing options are close to what solid hardwood offers.
Which lasts longer, engineered or solid hardwood?
Solid hardwood has the longest proven track record. Premium engineered at 4mm or above lasts decades. Thin engineered is essentially replacement flooring.
Is engineered hardwood better for Michigan basements?
Generally yes. Engineered hardwood is more dimensionally stable over concrete and below grade. Not every engineered product is below-grade approved, so always check the manufacturer's spec sheet.
What's the best hardwood flooring for Michigan's climate?
For above-grade installations with wood subfloors and controlled humidity, solid hardwood is an excellent choice. For slabs, basements, or radiant heat, engineered hardwood is the better option. Either way, proper acclimation and humidity control are essential in Michigan's climate.
