Why Humidity Decides Everything
Wood is hygroscopic — it absorbs and releases moisture with the air, and the dimension changes as it does.
Massachusetts homes swing from very dry in winter (heating drives indoor relative humidity into the 20–30% range) to humid in summer (often 50–60%+). Solid wood expands across that swing and contracts back, opening winter gaps between boards and risking summer cupping if moisture is high. Engineered wood, built as a thin real-wood veneer over a cross-laminated plywood core, moves far less. LVP, being plastic, does not absorb moisture and barely moves at all. The wider the humidity swing in a given home, the more that stability matters.
The Grade Level Rule
Where the floor sits relative to grade rules products in or out.
Solid hardwood is an above-grade only product — it cannot be installed below grade (basements) because ground moisture migrating up through a slab will destroy it. Engineered wood can sometimes go on or below grade if the slab is dry and a moisture barrier is used. LVP is the only one of the three that is genuinely at home over a basement slab, because it is waterproof and unaffected by slab moisture. This single rule eliminates options before appearance is even considered.
The Three Floors, Compared
Each trades refinishability and feel against stability and cost.
| Type | Grade level | Refinishing |
|---|---|---|
| Solid hardwood | Above grade only | Many times (3/4 in wear) |
| Engineered wood | On/above, some below | 1–2 times (thin veneer) |
| Luxury vinyl plank | Any, incl. basements | Not refinishable — replace |
Solid hardwood's advantage is longevity through refinishing: a 3/4-inch solid floor can be sanded and refinished several times over decades, effectively renewing it. Engineered wood's thin veneer allows only one or two refinishes. LVP cannot be refinished at all — when it wears, planks are swapped. That refinishing math is why solid hardwood remains the long-horizon choice in living spaces that stay above grade.
The Refinishing Advantage
Refinishing is the lever that makes solid wood last generations.
Sanding back to bare wood and re-staining removes scratches, dents, and dated colors, returning a floor to new — see our hardwood refinishing work. A solid 3/4-inch floor has enough wear layer for several cycles; many original New England floors are on their third or fourth refinish a century later. Engineered floors with a 4mm+ veneer can take one careful refinish; thinner veneers cannot. LVP's wear layer is a printed film that cannot be sanded.
How to Choose by Room
The decision is usually made room by room, not house-wide.
Above-grade living areas and bedrooms favor solid or engineered wood for warmth and refinishability. Basements, mudrooms, and slab-on-grade additions favor LVP for its waterproofing and stability. Kitchens and baths, where spills are routine, lean LVP or engineered. Matching the product to the room's moisture exposure and grade level — rather than picking one floor for the whole house — is what avoids the gapping, cupping, and slab-moisture failures that plague mismatched installs.
