Engineered vs Solid Hardwood

Both engineered and solid are real hardwood. Same wood, same look, same finish. The difference is structural - and it matters.

Construction

• Solid: one piece of hardwood, 3/4" thick, tongue-and-groove.
• Engineered: wear layer of real hardwood (1 – 6 mm) on a multi-ply plywood core. Total thickness 1/2" – 5/8".

Refinishability

• Solid: 4 – 7 full refinishes possible over the floor's lifetime.
• Engineered with 4 – 6 mm wear layer: 2 – 4 refinishes possible.
• Engineered with 1 – 2 mm wear layer: cannot be refinished; replaced at end of life.

Subfloor compatibility

• Solid: nail-down to plywood subfloor only. Cannot install over slab without significant prep.
• Engineered: floats, glues down, or nails. Works over slab - the dominant choice for post-1990 Inland Empire homes.

Plank widths

• Solid: stable up to about 4" – 5". Wider widths are prone to cupping in our climate.
• Engineered: stable at 6" – 9" wide planks. The reason wide-plank floors are almost always engineered.

Cost

• Solid: $9 – $16 per sq ft installed.
• Engineered: $9 – $18 per sq ft installed (wider range due to wear-layer variation).
• Winner: Comparable at similar quality tiers.

Lifespan

• Solid: 75 – 100+ years with refinishing.
• Engineered (premium): 30 – 50 years with refinishing.
• Engineered (budget): 15 – 20 years.

Climate stability in the Inland Empire

• Solid: more sensitive to humidity swings. Requires whole-house humidifier and tight humidity control.
• Engineered: plywood core resists movement. More forgiving of humidity variation.

When to choose solid

• Raised-foundation home.
• Long-term ownership (decades).
• Aesthetic priority on traditional 2-1/4" – 5" plank widths.
• Historic home where solid is appropriate.

When to choose engineered

• Slab subfloor (most newer Inland Empire homes).
• Want wider planks (5"+).
• Variable humidity rooms.
• Below-grade application.

What we install most

• Older raised-foundation homes: solid hardwood, refinish or new.
• Newer slab homes: wide-plank engineered hardwood.
• Custom and upper-tier homes: wide-plank European oak engineered.
