Engineered vs. Solid Hardwood: What's the Difference?

What's the Actual Difference?

Solid hardwood is exactly what it sounds like: a plank of wood milled from a single piece of timber, typically 3/4" thick. Engineered hardwood has a real hardwood veneer on top — the part you see and walk on — bonded to multiple layers of plywood or high-density fibreboard underneath. Both products look identical from above. The difference is entirely in the construction.

Why Engineered Exists

Solid wood moves — a lot. It expands and contracts with changes in humidity and temperature, which is why it can't be glued or nailed directly to concrete, and why it's problematic below grade or in high-moisture rooms. Engineered hardwood was developed to solve this. The cross-ply construction of the base layers works against the movement of the wood veneer, resulting in a much more stable product.

In BC's climate — wet winters, dry summers — this stability matters. Engineered hardwood performs reliably in conditions that would cause solid wood to cup or gap.

Where Each Works Best

Solid hardwood is ideal for main floors and upper levels in homes with plywood subfloors. It can be nailed or stapled — never glued or floated — and needs at least 18" of ventilated crawl space below if installed over a crawl space. It's the better choice for homes where you want the option to refinish many times over a 50–80 year lifespan.

Engineered hardwood works almost everywhere: over concrete slabs, in basement level rooms (above grade only — not true basements with moisture issues), in condos and strata buildings, and in the Lower Mainland's humid coastal climate. It can be glued, nailed, stapled, or floated.

• Condos and strata: engineered only — floating install required to meet IIC sound ratings
• Basements above grade: engineered, with a moisture barrier
• True basements or below-grade rooms: vinyl plank — neither hardwood type is appropriate
• Heritage homes with original subfloor: solid hardwood, if the subfloor is sound

Can You Refinish Engineered Hardwood?

Yes — but fewer times than solid. A quality engineered floor with a 3–6mm hardwood layer can typically be sanded and refinished 2–4 times. A thin-veneer engineered floor (1–2mm) can be screen-and-recoated once or twice but not fully sanded.

For comparison, a 3/4" solid hardwood floor can be refinished 6–8 times over its lifetime. If longevity and the ability to change the stain colour decades from now matters to you, solid hardwood is worth the premium.
