Metro Vancouver is full of beautiful homes with hardwood floors that have seen decades of use. Old-growth fir in pre-war Eastside bungalows. Oak in Burnaby split-levels from the 70s. Maple in Coquitlam homes built in the 90s. In most cases, those floors aren't at the end of their life — they just need refinishing.
The question homeowners most often ask us: is it worth refinishing, or should I just replace? The honest answer depends on what species you have, how thick the wear layer is, and what condition the boards are in. Here's how to think through it.
Signs Your Hardwood Needs Refinishing (Not Just Cleaning)
A lot of hardwood floors that look bad just need a deep clean and some screening — not a full sand. Others genuinely need the full refinishing treatment. Here's how to tell:
- Grey or white discolouration: This is oxidation — moisture has penetrated the finish and reached the wood. A full sand-and-refinish is required. Cleaning won't touch it.
- Deep scratches that catch a fingernail: Surface scratches can sometimes be screened and recoated. Deep scratches that go into the wood itself need sanding down past the damage.
- Finish peeling or flaking: The old finish has failed. You can't coat over failing finish — the new coat won't bond. Full refinish required.
- Cupping or crowning: Boards that are higher at the edges (cupping) or centre (crowning) indicate a moisture problem. The moisture issue must be resolved first, then the floor can be sanded flat and refinished.
- General dullness that doesn't respond to cleaning: Often just a screening and recoat — a lighter process that doesn't require full sanding.
Refinish vs. Replace: The Cost Comparison
For most solid hardwood floors in good structural condition, refinishing wins on cost — often by a significant margin. Here's a realistic comparison for a 500 sq ft main floor area in Metro Vancouver:
| Option | Estimated Cost (500 sq ft) | Timeline | Result |
|---|---|---|---|
| Screen and recoat | $750–$1,500 | 1–2 days | Restored sheen, minor scratch removal |
| Full sand and refinish | $2,500–$4,500 | 3–5 days | Like-new surface, colour change possible |
| Replace with engineered hardwood | $6,000–$10,000 | 2–4 days | New floor, modern profile, floating install |
| Replace with solid hardwood | $9,000–$16,000+ | 3–5 days + acclimation | New floor, refinishable for decades |
The calculus shifts toward replacement when boards are structurally damaged (rot, insect damage, extensive cupping that won't lie flat), when you've exhausted the refinishing cycles on engineered hardwood, or when you want a significant style change and the existing species or plank width doesn't suit your vision.
How the Refinishing Process Works
A full sand-and-refinish involves several distinct stages:
- Sanding (rough cut): A drum or belt sander removes the old finish and a thin layer of wood. This flattens the floor and removes all surface damage. The room needs to be clear of furniture — dust containment is set up to protect the rest of the home.
- Edge sanding: A smaller edger sands the perimeter within a few inches of the walls where the drum sander can't reach.
- Screening (fine cut): A buffer with a screen disk smooths the surface after rough sanding and between finish coats.
- Staining (optional): If you're changing the colour, stain is applied and allowed to penetrate before sealing. This is your opportunity to go lighter, darker, or more warm/cool.
- Finish coats: Typically two to three coats of polyurethane, oil-modified, or water-based finish. Water-based dries faster and has less odour; oil-modified is more durable and adds warmth to the colour.
The floor needs to cure before heavy use. We recommend keeping the space clear for 24 hours after the final coat, and avoiding rugs for 2–4 weeks while the finish fully hardens.
How Many Times Can You Refinish?
This is the most important technical question — and the answer depends entirely on whether you have solid hardwood or engineered hardwood:
- Solid hardwood (¾" thick): Can typically be refinished 5–8 times over its lifetime. Each full sand removes roughly 1/32" to 1/16" of wood. A 75-year-old fir floor in a Vancouver heritage home may have been refinished two or three times and still have plenty of life left.
- Engineered hardwood (2–6mm wear layer): Can be refinished 1–3 times depending on the wear layer thickness. A 2mm wear layer is at the low end — often only one light refinish is possible. A 4–6mm wear layer gives you more options. If you can't feel the groove between boards with your fingernail, you're likely at or near the minimum safe thickness.
If you're not sure what you have, we can assess during a free consultation. The species, thickness, and wear layer condition all factor into whether refinishing is viable.
Vancouver-Specific Considerations
BC's climate adds some complexity that homeowners elsewhere don't face to the same degree:
- Old-growth fir: Many pre-1950s Vancouver homes have old-growth Douglas fir floors. This wood is denser and harder than modern second-growth fir, takes stain beautifully, and is worth every effort to preserve. Don't replace it with engineered hardwood unless the structural condition genuinely leaves no alternative.
- Wet season timing: Vancouver's wet winters (Oct–March) bring elevated indoor humidity. Refinishing is best done in drier months (May–September) when indoor humidity is lower and finish cures more predictably. If refinishing in winter, ensure the home is properly heated and ventilated.
- Radiant heat and in-floor heating: If your home has radiant in-floor heating, inform your refinisher. Water-based finishes are generally preferred over oil-modified on heated floors as they're more flexible with temperature cycling.
- Heritage and strata restrictions: Some heritage buildings and strata corporations restrict the type of finish allowed or require specific sound ratings. Check your strata bylaws if applicable.
When Replacement Makes More Sense
There are situations where we'll recommend replacement over refinishing — and we'll tell you honestly:
- The wear layer is too thin to safely sand (especially engineered hardwood that's been refinished before)
- Structural damage — rot, significant cupping that won't flatten, broken boards in more than isolated areas
- You want a significantly different style that the existing species can't achieve (e.g., a wide-plank light oak look from a narrow-strip dark walnut floor)
- You're doing a full renovation where the subfloor needs work anyway
In those cases, engineered hardwood is often the most practical replacement — it handles BC's humidity better than solid hardwood, can float over radiant heat, and is available in wide planks that read as premium in listing photos and real life.
