Real hardwood flooring still tops resale value and design preference in Ottawa kitchens, living rooms, dining rooms, and bedrooms — but the choice between solid hardwood and engineered hardwood is more consequential than most homeowners realize. Ottawa's brutal humidity swing (15-25% RH in winter, 60-75% in summer) punishes solid hardwood more than almost any other Canadian climate zone. Basements, in-floor radiant heat installations, and concrete-on-slab installs all push the right answer toward engineered. This guide compares both products on the dimensions that matter for an Ottawa install ...
Solid hardwood is a single piece of solid wood (typically oak, maple, or hickory in Canadian production), 3/4" thick, tongue-and-groove edges, finished either pre-finished from the factory or site-finished after install. Engineered hardwood is a multi-layer composite: a real-wood top veneer (1.5-6 mm thick depending on product tier), bonded to a cross-laminated plywood or HDF core. The top veneer is the same species and can be the same visual quality as solid hardwood; the difference is what's u...
Solid hardwood expands and contracts seasonally with humidity. In Ottawa, the winter-to-summer humidity swing causes solid wood floors to gap noticeably in winter (1-3 mm between boards is normal for solid oak in unhumidified Ottawa homes) and tighten in summer. Engineered hardwood's cross-laminated core resists this expansion almost completely — gaps are minimal year-round, cupping and crowning are far less common. For homes without active humidification (most Ottawa homes), engineered hardwood...
Solid hardwood install methods: nail-down (only over plywood subfloor; cannot install over concrete slab). Site-finishing optional. Engineered hardwood install methods: nail-down (over plywood), glue-down (over plywood or concrete), or click-lock floating (over almost any flat surface including concrete with vapour barrier). For Ottawa basement installs, engineered is the only viable choice because solid wood cannot install over concrete. For main floors over plywood, both work — solid hardwood ...
Solid hardwood (red oak, maple, ash, ~3/4" thick): $5.50-$8.50/sq ft material + $3.50-$5.50/sq ft install = $9.00-$14.00/sq ft total. Premium solid (white oak, walnut, hickory, character grade): $8.50-$14.00/sq ft material + $4.00-$6.50/sq ft install = $12.50-$20.50/sq ft. Engineered hardwood (entry-level, 2 mm veneer): $4.50-$6.50/sq ft material + $3.00-$5.00/sq ft install = $7.50-$11.50/sq ft. Mid-range engineered (3-4 mm veneer): $6.50-$10.00/sq ft + $3.50-$5.50/sq ft = $10.00-$15.50/sq ft. P...
Solid hardwood can be sanded and refinished 5-10 times over its lifespan (60-100+ years total). Engineered hardwood refinishability depends entirely on veneer thickness: 1.5-2 mm veneer cannot be sanded (only screened-and-recoated); 3-4 mm veneer can be sanded once; 5-6 mm veneer can be sanded 2-3 times. For an Ottawa homeowner planning to stay 30+ years, solid hardwood's refinishability is a meaningful long-term cost advantage. For 10-15 year ownership windows, the difference rarely matters bec...
Solid hardwood is generally NOT recommended over in-floor radiant heat — the heating cycle accelerates expansion/contraction and most manufacturers void warranty. Engineered hardwood IS rated for radiant heat up to 27-28°C surface temperature (verify per manufacturer). Quarter-sawn or rift-sawn solid (more dimensionally stable than plain-sawn) is sometimes used over radiant heat with careful humidity control. For any Ottawa install over radiant heat, engineered hardwood is the default choice.
For appearance and feel underfoot, premium engineered hardwood (4-6 mm veneer) is essentially indistinguishable from solid hardwood. For refinishability and lifespan, solid hardwood is longer-lived (5-10 refinishes vs 1-3). For humidity stability in Ottawa's climate, engineered is materially better.
Yes — engineered hardwood is one of the few hardwood-style options rated for below-grade installation. Use the glue-down or floating click-lock method with a vapour barrier over concrete. Solid hardwood cannot install in basements because it requires nailing into a plywood subfloor.
Installed pricing in 2026: solid hardwood $9.00-$20.50/sq ft depending on species and grade. Engineered hardwood $7.50-$22.50/sq ft depending on veneer thickness and origin. Premium European wide-plank engineered tops the range; entry-level domestic engineered is the most affordable real-wood option.
Scratch resistance depends on the finish coating, not whether the floor is solid or engineered. UV-cured aluminum oxide finishes (standard on most pre-finished products) resist scratching well. The wood species also matters — hickory and maple are harder than oak; walnut is softer.
Yes if the top veneer is at least 3 mm thick. 3-4 mm veneer products allow one full sand-and-refinish. 5-6 mm veneer (premium European products) allow 2-3 refinishes. Entry-level engineered with 1.5-2 mm veneer cannot be sanded — only screened-and-recoated.
