Complete guide to engineered hardwood: solid vs engineered comparison, wear layer thickness, refinishing, installation for Canadian homes
Engineered hardwood flooring combines authentic real wood beauty with superior dimensional stability, making it the ideal choice for Canadian homes experiencing dramatic seasonal humidity swings. This multi-layer construction features a real hardwood wear layer bonded to a cross-grain plywood core, delivering genuine wood appearance while resisting the cupping, gapping, and warping that plague solid hardwood in our climate. Understanding the critical differences between solid and engineered hardwood, wear layer specifications, and proper installation methods ensures you make informed decisions for your $8-15 per square foot investment.
This fundamental choice impacts everything: installation costs, long-term stability, refinishing potential, and performance through Canadian winters. Most homeowners don't realize these are entirely different products with distinct advantages suited to different applications.
Milled from a single piece of solid wood, typically 3/4" (19mm) thick throughout the entire plank. Pure hardwood from top to bottom—what you see is what you get. Traditional flooring used for centuries in North American homes.
Multi-layer construction with real hardwood wear layer (2-6mm thick) bonded to plywood core (5-9 cross-grain layers). Top layer provides authentic wood appearance while engineered core delivers dimensional stability impossible with solid wood.
When buying engineered hardwood, wear layer thickness determines your floor's entire value proposition. This specification separates disposable flooring from products approaching solid hardwood's longevity. Always verify this before purchasing—manufacturers often obscure this critical detail.

Hardest Domestic Species: Nearly indestructible durability for extreme traffic and pet owners.
Characteristics: Dramatic grain variation and pronounced character marks. Extreme light-to-dark color variation even within single planks creates rustic, informal appearance.
Best For: Rustic/farmhouse aesthetics, large dogs, high-traffic commercial-residential spaces. Commercial-grade toughness makes it practically maintenance-free for typical residential use.
Traditional Canadian Favorite: Most economical domestic hardwood with excellent availability across Eastern Canada.
Characteristics: Prominent open grain with distinct cathedral patterns. Warm pinkish-tan to reddish-brown tones. Accepts stains beautifully allowing wide color customization.
Best For: Budget-conscious projects, traditional aesthetics, homeowners wanting stain flexibility. Balance of cost and performance makes it Canada's most popular hardwood species.
Yes, for most applications. Engineered hardwood's cross-grain plywood core resists expansion and contraction from Canadian humidity swings dramatically better than solid hardwood. This means minimal seasonal gapping, lower cupping risk, and stable year-round performance. Engineered works in basements and with radiant heating where solid fails. The only trade-off: solid hardwood can be refinished 4-7 times versus engineered's 0-3 times depending on wear layer thickness.
Minimum 4mm for any refinishing potential, but 5-6mm is strongly recommended for long-term value. Budget engineered with 2-3mm wear layers cannot be refinished and must be replaced when worn (typically 15-20 years). Premium 5-6mm wear layers support 2-3 full refinishings, extending lifespan to 40-60 years and approaching solid hardwood's longevity while maintaining superior dimensional stability.
Yes, when properly prepared. Engineered hardwood's dimensional stability handles below-grade installations far better than solid hardwood. Requirements: moisture testing showing less than 3 lbs/1000 sqft/24hr, 6-mil vapor barrier installation, dehumidifier maintaining 35-50% humidity year-round, and no previous flooding history. If basement has flooded or moisture tests fail, waterproof vinyl flooring is the safer choice.
Choose Hickory (Janka 1820) or Hard Maple (Janka 1450) for maximum durability with pets. Hickory is the hardest common domestic species, nearly indestructible against dog claws and dropped items. Hard Maple offers excellent durability with a cleaner contemporary appearance. Avoid soft species like Cherry (Janka 995) or Walnut (Janka 1010) with pets. Minimum 1200 Janka rating recommended for any household with animals.
Material costs range from $4-14 per square foot depending on quality. Budget engineered (2-3mm wear) costs $4-6/sqft, mid-grade (4mm wear) runs $6-9/sqft, and premium (5-6mm wear) costs $9-14/sqft. Installation adds $2-7/sqft: floating installation $2-4/sqft, glue-down $3-6/sqft, nail-down $4-7/sqft. Total project costs typically range $8-20/sqft installed depending on product quality and installation method.
It depends entirely on wear layer thickness. Engineered with 2mm wear layers cannot be refinished at all. 3mm allows light screening and recoating only. 4mm supports 1 light sanding. 5-6mm wear layers enable 2-3 full refinishings just like solid hardwood. Always verify wear layer specifications before purchasing, as this determines whether your floor is essentially disposable or can be restored multiple times over decades.
No, engineered hardwood is NOT waterproof despite being more moisture-stable than solid hardwood. It's real wood that will swell and damage from prolonged water exposure. Standing water from appliance leaks, pet accidents left overnight, or bathroom flooding causes permanent damage including staining, cupping, and core delamination. Not recommended for full bathrooms. For true waterproof flooring, choose WPC/SPC vinyl or porcelain tile instead.
Lifespan varies dramatically by wear layer thickness: Budget products with 2-3mm wear last 15-20 years until replacement required. Mid-grade 4mm wear extends to 25-35 years with one refinishing. Premium 5-6mm wear lasts 40-60 years with 2-3 refinishings. Actual longevity also depends on wood species hardness, traffic levels, maintenance quality, and moisture exposure. Premium engineered approaches solid hardwood's multi-generational lifespan.
Floating installation is genuinely DIY-friendly with basic skills. Click-lock planks install similarly to laminate requiring only saw, spacers, underlayment, and patience. First-timers average 4-6 hours per 100 sqft. However, glue-down and nail-down methods require professional expertise as mistakes are expensive and permanent. Hire professionals for stairs, complex layouts, large projects over 2000 sqft, or if lacking proper tools and time. Professional installation costs $3-7/sqft.
Yes, real hardwood flooring (solid or engineered) commands significant resale premiums. Buyers perceive hardwood as permanent, high-quality flooring worth paying for. Well-maintained engineered hardwood can recover 75-100% of installation costs at resale. Choose popular species like White Oak or Maple for broadest buyer appeal. Condition is critical: worn or damaged floors hurt value more than quality carpet or vinyl. Refinish before selling if showing wear.
